One of: + +* "Compile" - treat the file as source code: compile and run it +* "Embed" - embed the file into the target binary as a resource +* "Copy" - copy the file to the target directory +* "None" - do nothing with this file + +#### Examples +Embed all PNGs into the target binary + +```lua +configuration "**.png" + buildaction "Embed" +``` + +[Back to top](#table-of-contents) + +--- +### buildoptions({_options_...}) +Passes arguments direction to the compiler command line.

+ +<p> +Lua is an extension programming language designed to support +general procedural programming with data description +facilities. +Lua also offers good support for object-oriented programming, +functional programming, and data-driven programming. +Lua is intended to be used as a powerful, lightweight, +embeddable scripting language for any program that needs one. +Lua is implemented as a library, written in <em>clean C</em>, +the common subset of Standard C and C++. + + +<p> +As an extension language, Lua has no notion of a "main" program: +it only works <em>embedded</em> in a host client, +called the <em>embedding program</em> or simply the <em>host</em>. +The host program can invoke functions to execute a piece of Lua code, +can write and read Lua variables, +and can register C functions to be called by Lua code. +Through the use of C functions, Lua can be augmented to cope with +a wide range of different domains, +thus creating customized programming languages sharing a syntactical framework. +The Lua distribution includes a sample host program called <code>lua</code>, +which uses the Lua library to offer a complete, standalone Lua interpreter, +for interactive or batch use. + + +<p> +Lua is free software, +and is provided as usual with no guarantees, +as stated in its license. +The implementation described in this manual is available +at Lua's official web site, <code>www.lua.org</code>. + + +<p> +Like any other reference manual, +this document is dry in places. +For a discussion of the decisions behind the design of Lua, +see the technical papers available at Lua's web site. +For a detailed introduction to programming in Lua, +see Roberto's book, <em>Programming in Lua</em>. + + + +<h1>2 – <a name="2">Basic Concepts</a></h1> + +<p> +This section describes the basic concepts of the language. + + + +<h2>2.1 – <a name="2.1">Values and Types</a></h2> + +<p> +Lua is a <em>dynamically typed language</em>. +This means that +variables do not have types; only values do. +There are no type definitions in the language. +All values carry their own type. + + +<p> +All values in Lua are <em>first-class values</em>. +This means that all values can be stored in variables, +passed as arguments to other functions, and returned as results. + + +<p> +There are eight basic types in Lua: +<em>nil</em>, <em>boolean</em>, <em>number</em>, +<em>string</em>, <em>function</em>, <em>userdata</em>, +<em>thread</em>, and <em>table</em>. +<em>Nil</em> is the type of the value <b>nil</b>, +whose main property is to be different from any other value; +it usually represents the absence of a useful value. +<em>Boolean</em> is the type of the values <b>false</b> and <b>true</b>. +Both <b>nil</b> and <b>false</b> make a condition false; +any other value makes it true. +<em>Number</em> represents both +integer numbers and real (floating-point) numbers. +<em>String</em> represents immutable sequences of bytes. + +Lua is 8-bit clean: +strings can contain any 8-bit value, +including embedded zeros ('<code>\0</code>'). +Lua is also encoding-agnostic; +it makes no assumptions about the contents of a string. + + +<p> +The type <em>number</em> uses two internal representations, +one called <em>integer</em> and the other called <em>float</em>. +Lua has explicit rules about when each representation is used, +but it also converts between them automatically as needed (see <a href="#3.4.3">§3.4.3</a>). +Therefore, +the programmer may choose to mostly ignore the difference +between integers and floats +or to assume complete control over the representation of each number. +Standard Lua uses 64-bit integers and double-precision (64-bit) floats, +but you can also compile Lua so that it +uses 32-bit integers and/or single-precision (32-bit) floats. +The option with 32 bits for both integers and floats +is particularly attractive +for small machines and embedded systems. +(See macro <code>LUA_32BITS</code> in file <code>luaconf.h</code>.) + + +<p> +Lua can call (and manipulate) functions written in Lua and +functions written in C (see <a href="#3.4.10">§3.4.10</a>). +Both are represented by the type <em>function</em>. + + +<p> +The type <em>userdata</em> is provided to allow arbitrary C data to +be stored in Lua variables. +A userdata value represents a block of raw memory. +There are two kinds of userdata: +<em>full userdata</em>, +which is an object with a block of memory managed by Lua, +and <em>light userdata</em>, +which is simply a C pointer value. +Userdata has no predefined operations in Lua, +except assignment and identity test. +By using <em>metatables</em>, +the programmer can define operations for full userdata values +(see <a href="#2.4">§2.4</a>). +Userdata values cannot be created or modified in Lua, +only through the C API. +This guarantees the integrity of data owned by the host program. + + +<p> +The type <em>thread</em> represents independent threads of execution +and it is used to implement coroutines (see <a href="#2.6">§2.6</a>). +Lua threads are not related to operating-system threads. +Lua supports coroutines on all systems, +even those that do not support threads natively. + + +<p> +The type <em>table</em> implements associative arrays, +that is, arrays that can be indexed not only with numbers, +but with any Lua value except <b>nil</b> and NaN. +(<em>Not a Number</em> is a special numeric value used to represent +undefined or unrepresentable results, such as <code>0/0</code>.) +Tables can be <em>heterogeneous</em>; +that is, they can contain values of all types (except <b>nil</b>). +Any key with value <b>nil</b> is not considered part of the table. +Conversely, any key that is not part of a table has +an associated value <b>nil</b>. + + +<p> +Tables are the sole data-structuring mechanism in Lua; +they can be used to represent ordinary arrays, sequences, +symbol tables, sets, records, graphs, trees, etc. +To represent records, Lua uses the field name as an index. +The language supports this representation by +providing <code>a.name</code> as syntactic sugar for <code>a["name"]</code>. +There are several convenient ways to create tables in Lua +(see <a href="#3.4.9">§3.4.9</a>). + + +<p> +We use the term <em>sequence</em> to denote a table where +the set of all positive numeric keys is equal to {1..<em>n</em>} +for some non-negative integer <em>n</em>, +which is called the length of the sequence (see <a href="#3.4.7">§3.4.7</a>). + + +<p> +Like indices, +the values of table fields can be of any type. +In particular, +because functions are first-class values, +table fields can contain functions. +Thus tables can also carry <em>methods</em> (see <a href="#3.4.11">§3.4.11</a>). + + +<p> +The indexing of tables follows +the definition of raw equality in the language. +The expressions <code>a[i]</code> and <code>a[j]</code> +denote the same table element +if and only if <code>i</code> and <code>j</code> are raw equal +(that is, equal without metamethods). +In particular, floats with integral values +are equal to their respective integers +(e.g., <code>1.0 == 1</code>). +To avoid ambiguities, +any float with integral value used as a key +is converted to its respective integer. +For instance, if you write <code>a[2.0] = true</code>, +the actual key inserted into the table will be the +integer <code>2</code>. +(On the other hand, +2 and "<code>2</code>" are different Lua values and therefore +denote different table entries.) + + +<p> +Tables, functions, threads, and (full) userdata values are <em>objects</em>: +variables do not actually <em>contain</em> these values, +only <em>references</em> to them. +Assignment, parameter passing, and function returns +always manipulate references to such values; +these operations do not imply any kind of copy. + + +<p> +The library function <a href="#pdf-type"><code>type</code></a> returns a string describing the type +of a given value (see <a href="#6.1">§6.1</a>). + + + + + +<h2>2.2 – <a name="2.2">Environments and the Global Environment</a></h2> + +<p> +As will be discussed in <a href="#3.2">§3.2</a> and <a href="#3.3.3">§3.3.3</a>, +any reference to a free name +(that is, a name not bound to any declaration) <code>var</code> +is syntactically translated to <code>_ENV.var</code>. +Moreover, every chunk is compiled in the scope of +an external local variable named <code>_ENV</code> (see <a href="#3.3.2">§3.3.2</a>), +so <code>_ENV</code> itself is never a free name in a chunk. + + +<p> +Despite the existence of this external <code>_ENV</code> variable and +the translation of free names, +<code>_ENV</code> is a completely regular name. +In particular, +you can define new variables and parameters with that name. +Each reference to a free name uses the <code>_ENV</code> that is +visible at that point in the program, +following the usual visibility rules of Lua (see <a href="#3.5">§3.5</a>). + + +<p> +Any table used as the value of <code>_ENV</code> is called an <em>environment</em>. + + +<p> +Lua keeps a distinguished environment called the <em>global environment</em>. +This value is kept at a special index in the C registry (see <a href="#4.5">§4.5</a>). +In Lua, the global variable <a href="#pdf-_G"><code>_G</code></a> is initialized with this same value. +(<a href="#pdf-_G"><code>_G</code></a> is never used internally.) + + +<p> +When Lua loads a chunk, +the default value for its <code>_ENV</code> upvalue +is the global environment (see <a href="#pdf-load"><code>load</code></a>). +Therefore, by default, +free names in Lua code refer to entries in the global environment +(and, therefore, they are also called <em>global variables</em>). +Moreover, all standard libraries are loaded in the global environment +and some functions there operate on that environment. +You can use <a href="#pdf-load"><code>load</code></a> (or <a href="#pdf-loadfile"><code>loadfile</code></a>) +to load a chunk with a different environment. +(In C, you have to load the chunk and then change the value +of its first upvalue.) + + + + + +<h2>2.3 – <a name="2.3">Error Handling</a></h2> + +<p> +Because Lua is an embedded extension language, +all Lua actions start from C code in the host program +calling a function from the Lua library. +(When you use Lua standalone, +the <code>lua</code> application is the host program.) +Whenever an error occurs during +the compilation or execution of a Lua chunk, +control returns to the host, +which can take appropriate measures +(such as printing an error message). + + +<p> +Lua code can explicitly generate an error by calling the +<a href="#pdf-error"><code>error</code></a> function. +If you need to catch errors in Lua, +you can use <a href="#pdf-pcall"><code>pcall</code></a> or <a href="#pdf-xpcall"><code>xpcall</code></a> +to call a given function in <em>protected mode</em>. + + +<p> +Whenever there is an error, +an <em>error object</em> (also called an <em>error message</em>) +is propagated with information about the error. +Lua itself only generates errors whose error object is a string, +but programs may generate errors with +any value as the error object. +It is up to the Lua program or its host to handle such error objects. + + +<p> +When you use <a href="#pdf-xpcall"><code>xpcall</code></a> or <a href="#lua_pcall"><code>lua_pcall</code></a>, +you may give a <em>message handler</em> +to be called in case of errors. +This function is called with the original error message +and returns a new error message. +It is called before the error unwinds the stack, +so that it can gather more information about the error, +for instance by inspecting the stack and creating a stack traceback. +This message handler is still protected by the protected call; +so, an error inside the message handler +will call the message handler again. +If this loop goes on for too long, +Lua breaks it and returns an appropriate message. + + + + + +<h2>2.4 – <a name="2.4">Metatables and Metamethods</a></h2> + +<p> +Every value in Lua can have a <em>metatable</em>. +This <em>metatable</em> is an ordinary Lua table +that defines the behavior of the original value +under certain special operations. +You can change several aspects of the behavior +of operations over a value by setting specific fields in its metatable. +For instance, when a non-numeric value is the operand of an addition, +Lua checks for a function in the field "<code>__add</code>" of the value's metatable. +If it finds one, +Lua calls this function to perform the addition. + + +<p> +The keys in a metatable are derived from the <em>event</em> names; +the corresponding values are called <em>metamethods</em>. +In the previous example, the event is <code>"add"</code> +and the metamethod is the function that performs the addition. + + +<p> +You can query the metatable of any value +using the <a href="#pdf-getmetatable"><code>getmetatable</code></a> function. + + +<p> +You can replace the metatable of tables +using the <a href="#pdf-setmetatable"><code>setmetatable</code></a> function. +You cannot change the metatable of other types from Lua +(except by using the debug library (<a href="#6.10">§6.10</a>)); +you must use the C API for that. + + +<p> +Tables and full userdata have individual metatables +(although multiple tables and userdata can share their metatables). +Values of all other types share one single metatable per type; +that is, there is one single metatable for all numbers, +one for all strings, etc. +By default, a value has no metatable, +but the string library sets a metatable for the string type (see <a href="#6.4">§6.4</a>). + + +<p> +A metatable controls how an object behaves in +arithmetic operations, bitwise operations, +order comparisons, concatenation, length operation, calls, and indexing. +A metatable also can define a function to be called +when a userdata or a table is garbage collected (<a href="#2.5">§2.5</a>). + + +<p> +A detailed list of events controlled by metatables is given next. +Each operation is identified by its corresponding event name. +The key for each event is a string with its name prefixed by +two underscores, '<code>__</code>'; +for instance, the key for operation "add" is the +string "<code>__add</code>". +Note that queries for metamethods are always raw; +the access to a metamethod does not invoke other metamethods. +You can emulate how Lua queries a metamethod for an object <code>obj</code> +with the following code: + +<pre> + rawget(getmetatable(obj) or {}, "__" .. event_name) +</pre> + +<p> +For the unary operators (negation, length, and bitwise not), +the metamethod is computed and called with a dummy second operand, +equal to the first one. +This extra operand is only to simplify Lua's internals +(by making these operators behave like a binary operation) +and may be removed in future versions. +(For most uses this extra operand is irrelevant.) + + + +<ul> + +<li><b>"add": </b> +the <code>+</code> operation. + +If any operand for an addition is not a number +(nor a string coercible to a number), +Lua will try to call a metamethod. +First, Lua will check the first operand (even if it is valid). +If that operand does not define a metamethod for the "<code>__add</code>" event, +then Lua will check the second operand. +If Lua can find a metamethod, +it calls the metamethod with the two operands as arguments, +and the result of the call +(adjusted to one value) +is the result of the operation. +Otherwise, +it raises an error. +</li> + +<li><b>"sub": </b> +the <code>-</code> operation. + +Behavior similar to the "add" operation. +</li> +

+Unlike other operations, +The less-equal operation can use two different events. +First, Lua looks for the "<code>__le</code>" metamethod in both operands, +like in the "lt" operation. +If it cannot find such a metamethod, +then it will try the "<code>__lt</code>" event, +assuming that <code>a <= b</code> is equivalent to <code>not (b < a)</code>. +As with the other comparison operators, +the

this event can be either a function or a table. +If it is a function, +it is called with <code>table</code>, <code>key</code>, and <code>value</code> as arguments. +If it is a table, +Lua does an indexing assignment to this table with the same key and value. +(This assignment is regular, not raw, +and therefore can trigger another metamethod.) + + +<p> +Whenever there is a "newindex"

+</ul> + + + + +<h2>2.5 – <a name="2.5">Garbage Collection</a></h2> + +<p> +Lua performs automatic memory management. +This means that +you do not have to worry about allocating memory for new objects +or freeing it when the objects are no longer needed. +Lua manages memory automatically by running +a <em>garbage collector</em> to collect all <em>dead objects</em> +(that is, objects that are no longer accessible from Lua). +All memory used by Lua is subject to automatic management: +strings, tables, userdata, functions, threads, internal structures, etc. + + +<p> +Lua implements an incremental mark-and-sweep collector. +It uses two numbers to control its garbage-collection cycles: +the <em>garbage-collector pause</em> and +the <em>garbage-collector step multiplier</em>. +Both use percentage points as units +(e.g., a value of 100 means an internal value of 1). + + +<p> +The garbage-collector pause +controls how long the collector waits before starting a new cycle. +Larger values make the collector less aggressive. +Values smaller than 100 mean the collector will not wait to +start a new cycle. +A value of 200 means that the collector waits for the total memory in use +to double before starting a new cycle. + + +<p> +The garbage-collector step multiplier +controls the relative speed of the collector relative to +memory allocation. +Larger values make the collector more aggressive but also increase +the size of each incremental step. +You should not use values smaller than 100, +because they make the collector too slow and +can result in the collector never finishing a cycle. +The default is 200, +which means that the collector runs at "twice" +the speed of memory allocation. + + +<p> +If you set the step multiplier to a very large number +(larger than 10% of the maximum number of +bytes that the program may use), +the collector behaves like a stop-the-world collector. +If you then set the pause to 200, +the collector behaves as in old Lua versions, +doing a complete collection every time Lua doubles its +memory usage. + + +<p> +You can change these numbers by calling <a href="#lua_gc"><code>lua_gc</code></a> in C +or <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> in Lua. +You can also use these functions to control +the collector directly (e.g., stop and restart it). + + + +<h3>2.5.1 – <a name="2.5.1">Garbage-Collection Metamethods</a></h3> + +<p> +You can set garbage-collector metamethods for tables +and, using the C API, +for full userdata (see <a href="#2.4">§2.4</a>). +These metamethods are also called <em>finalizers</em>. +Finalizers allow you to coordinate Lua's garbage collection +with external resource management +(such as closing files, network or database connections, +or freeing your own memory). + + +<p> +For an object (table or userdata) to be finalized when collected, +you must <em>mark</em> it for finalization. + +You mark an object for finalization when you set its metatable +and the metatable has a field indexed by the string "<code>__gc</code>". +Note that if you set a metatable without a <code>__gc</code> field +and later create that field in the metatable, +the object will not be marked for finalization. +However, after an object has been marked, +you can freely change the <code>__gc</code> field of its metatable. + + +<p> +When a marked object becomes garbage, +it is not collected immediately by the garbage collector. +Instead, Lua puts it in a list. +After the collection, +Lua goes through that list. +For each object in the list, +it checks the object's <code>__gc</code> metamethod: +If it is a function, +Lua calls it with the object as its single argument; +if the metamethod is not a function, +Lua simply ignores it. + + +<p> +At the end of each garbage-collection cycle, +the finalizers for objects are called in +the reverse order that the objects were marked for finalization, +among those collected in that cycle; +that is, the first finalizer to be called is the one associated +with the object marked last in the program. +The execution of each finalizer may occur at any point during +the execution of the regular code. + + +<p> +Because the object being collected must still be used by the finalizer, +that object (and other objects accessible only through it) +must be <em>resurrected</em> by Lua. +Usually, this resurrection is transient, +and the object memory is freed in the next garbage-collection cycle. +However, if the finalizer stores the object in some global place +(e.g., a global variable), +then the resurrection is permanent. +Moreover, if the finalizer marks a finalizing object for finalization again, +its finalizer will be called again in the next cycle where the +object is unreachable. +In any case, +the object memory is freed only in the GC cycle where +the object is unreachable and not marked for finalization. + + +<p> +When you close a state (see <a href="#lua_close"><code>lua_close</code></a>), +Lua calls the finalizers of all objects marked for finalization, +following the reverse order that they were marked. +If any finalizer marks objects for collection during that phase, +these marks have no effect. + + + + + +<h3>2.5.2 – <a name="2.5.2">Weak Tables</a></h3> + +<p> +A <em>weak table</em> is a table whose elements are +<em>weak references</em>. +A weak reference is ignored by the garbage collector. +In other words, +if the only references to an object are weak references, +then the garbage collector will collect that object. + + +<p> +A weak table can have weak keys, weak values, or both. +A table with weak keys allows the collection of its keys, +but prevents the collection of its values. +A table with both weak keys and weak values allows the collection of +both keys and values. +In any case, if either the key or the value is collected, +the whole pair is removed from the table. +The weakness of a table is controlled by the +<code>__mode</code> field of its metatable. +If the <code>__mode</code> field is a string containing the character '<code>k</code>', +the keys in the table are weak. +If <code>__mode</code> contains '<code>v</code>', +the values in the table are weak. + + +<p> +A table with weak keys and strong values +is also called an <em>ephemeron table</em>. +In an ephemeron table, +a value is considered reachable only if its key is reachable. +In particular, +if the only reference to a key comes through its value, +the pair is removed. + + +<p> +Any change in the weakness of a table may take effect only +at the next collect cycle. +In particular, if you change the weakness to a stronger mode, +Lua may still collect some items from that table +before the change takes effect. + + +<p> +Only objects that have an explicit construction +are removed from weak tables. +Values, such as numbers and light C functions, +are not subject to garbage collection, +and therefore are not removed from weak tables +(unless their associated values are collected). +Although strings are subject to garbage collection, +they do not have an explicit construction, +and therefore are not removed from weak tables. + + +<p> +Resurrected objects +(that is, objects being finalized +and objects accessible only through objects being finalized) +have a special behavior in weak tables. +They are removed from weak values before running their finalizers, +but are removed from weak keys only in the next collection +after running their finalizers, when such objects are actually freed. +This behavior allows the finalizer to access properties +associated with the object through weak tables. + + +<p> +If a weak table is among the resurrected objects in a collection cycle, +it may not be properly cleared until the next cycle. + + + + + + + +<h2>2.6 – <a name="2.6">Coroutines</a></h2> + +<p> +Lua supports coroutines, +also called <em>collaborative multithreading</em>. +A coroutine in Lua represents an independent thread of execution. +Unlike threads in multithread systems, however, +a coroutine only suspends its execution by explicitly calling +a yield function. + + +<p> +You create a coroutine by calling <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>. +Its sole argument is a function +that is the main function of the coroutine. +The <code>create</code> function only creates a new coroutine and +returns a handle to it (an object of type <em>thread</em>); +it does not start the coroutine. + + +<p> +You execute a coroutine by calling <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>. +When you first call <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>, +passing as its first argument +a thread returned by <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>, +the coroutine starts its execution, +at the first line of its main function. +Extra arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> are passed +as arguments to the coroutine's main function. +After the coroutine starts running, +it runs until it terminates or <em>yields</em>. + + +<p> +A coroutine can terminate its execution in two ways: +normally, when its main function returns +(explicitly or implicitly, after the last instruction); +and abnormally, if there is an unprotected error. +In case of normal termination, +<a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>true</b>, +plus any values returned by the coroutine main function. +In case of errors, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>false</b> +plus an error message. + + +<p> +A coroutine yields by calling <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>. +When a coroutine yields, +the corresponding <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns immediately, +even if the yield happens inside nested function calls +(that is, not in the main function, +but in a function directly or indirectly called by the main function). +In the case of a yield, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> also returns <b>true</b>, +plus any values passed to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>. +The next time you resume the same coroutine, +it continues its execution from the point where it yielded, +with the call to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a> returning any extra +arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>. + + +<p> +Like <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>, +the <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> function also creates a coroutine, +but instead of returning the coroutine itself, +it returns a function that, when called, resumes the coroutine. +Any arguments passed to this function +go as extra arguments to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>. +<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> returns all the values returned by <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>, +except the first one (the boolean error code). +Unlike <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>, +<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> does not catch errors; +any error is propagated to the caller. + + +<p> +As an example of how coroutines work, +consider the following code: + +<pre> + function foo (a) + print("foo", a) + return coroutine.yield(2*a) + end + + co = coroutine.create(function (a,b) + print("co-body", a, b) + local r = foo(a+1) + print("co-body", r) + local r, s = coroutine.yield(a+b, a-b) + print("co-body", r, s) + return b, "end" + end) + + print("main", coroutine.resume(co, 1, 10)) + print("main", coroutine.resume(co, "r")) + print("main", coroutine.resume(co, "x", "y")) + print("main", coroutine.resume(co, "x", "y")) +</pre><p> +When you run it, it produces the following output: + +<pre> + co-body 1 10 + foo 2 + main true 4 + co-body r + main true 11 -9 + co-body x y + main true 10 end + main false cannot resume dead coroutine +</pre> + +<p> +You can also create and manipulate coroutines through the C API: +see functions <a href="#lua_newthread"><code>lua_newthread</code></a>, <a

explained using the usual extended BNF notation, +in which +{<em>a</em>} means 0 or more <em>a</em>'s, and +[<em>a</em>] means an optional <em>a</em>. +Non-terminals are shown like non-terminal, +keywords are shown like <b>kword</b>, +and other terminal symbols are shown like ‘<b>=</b>’. +The complete syntax of Lua can be found in <a href="#9">§9</a> +at the end of this manual. + + + +<h2>3.1 – <a name="3.1">Lexical Conventions</a></h2> + +<p> +Lua is a free-form language. +It ignores spaces (including new lines) and comments +between lexical elements (tokens), +except as delimiters between names and keywords. + + +<p> +<em>Names</em> +(also called <em>identifiers</em>) +in Lua can be any string of letters, +digits, and underscores, +not beginning with a digit. +Identifiers are used to name variables, table fields, and labels. + + +<p> +The following <em>keywords</em> are reserved +and cannot be used as names: + + +<pre> + and break do else elseif end + false for function goto if in + local nil not or repeat return + then true until while +</pre> + +<p> +Lua is a case-sensitive language: +<code>and</code> is a reserved word, but <code>And</code> and <code>AND</code> +are two different, valid names. +As a convention, +programs should avoid creating +names that start with an underscore followed by +one or more uppercase letters (such as <a href="#pdf-_VERSION"><code>_VERSION</code></a>). + + +<p> +The following strings denote other tokens: + +<pre> + + - * / % ^ # + & ~ | << >> // + == ~= <= >= < > = + ( ) { } [ ] :: + ; : , . .. ... +</pre> + +<p> +<em>Literal strings</em> +can be delimited by matching single or double quotes, +and can contain the following C-like escape sequences: +'<code>\a</code>' (bell), +'<code>\b</code>' (backspace), +'<code>\f</code>' (form feed), +'<code>\n</code>' (newline), +'<code>\r</code>' (carriage return), +'<code>\t</code>' (horizontal tab), +'<code>\v</code>' (vertical tab), +'<code>\\</code>' (backslash), +'<code>\"</code>' (quotation mark [double quote]), +and '<code>\'</code>' (apostrophe [single quote]). +A backslash followed by a real newline +results in a newline in the string. +The escape sequence '<code>\z</code>' skips the following span +of white-space characters, +including line breaks; +it is particularly useful to break and indent a long literal string +into multiple lines without adding the newlines and spaces +into the string contents. + + +<p> +Strings in Lua can contain any 8-bit value, including embedded zeros, +which can be specified as '<code>\0</code>'. +More generally, +we can specify any byte in a literal string by its numerical value. +This can be done +with the escape sequence <code>\x<em>XX</em></code>, +where <em>XX</em> is a sequence of exactly two hexadecimal digits, +or with the escape sequence <code>\<em>ddd</em></code>, +where <em>ddd</em> is a sequence of up to three decimal digits. +(Note that if a decimal escape sequence is to be followed by a digit, +it must be expressed using exactly three digits.) + + +<p> +The UTF-8 encoding of a Unicode character +can be inserted in a literal string with +the escape sequence <code>\u{<em>XXX</em>}</code> +(note the mandatory enclosing brackets), +where <em>XXX</em> is a sequence of one or more hexadecimal digits +representing the character code point. + + +<p> +Literal strings can also be defined using a long format +enclosed by <em>long brackets</em>. +We define an <em>opening long bracket of level <em>n</em></em> as an opening +square bracket followed by <em>n</em> equal signs followed by another +opening square bracket. +So, an opening long bracket of level 0 is written as <code>[[</code>, +an opening long bracket of level 1 is written as <code>[=[</code>, +and so on. +A <em>closing long bracket</em> is defined similarly; +for instance, +a closing long bracket of level 4 is written as <code>]====]</code>. +A <em>long literal</em> starts with an opening long bracket of any level and +ends at the first closing long bracket of the same level. +It can contain any text except a closing bracket of the same level. +Literals in this bracketed form can run for several lines, +do not interpret any escape sequences, +and ignore long brackets of any other level. +Any kind of end-of-line sequence +(carriage return, newline, carriage return followed by newline, +or newline followed by carriage return) +is converted to a simple newline. + + +<p> +Any byte in a literal string not +explicitly affected by the previous rules represents itself. +However, Lua opens files for parsing in text mode, +and the system file functions may have problems with +some control characters. +So, it is safer to represent +non-text data as a quoted literal with +explicit escape sequences for non-text characters. + + +<p> +For convenience, +when the opening long bracket is immediately followed by a newline, +the newline is not included in the string. +As an example, in a system using ASCII +(in which '<code>a</code>' is coded as 97, +newline is coded as 10, and '<code>1</code>' is coded as 49), +the five literal strings below denote the same string: + +<pre> + a = 'alo\n123"' + a = "alo\n123\"" + a = '\97lo\10\04923"' + a = [[alo + 123"]] + a = [==[ + alo + 123"]==] +</pre> + +<p> +A <em>numerical constant</em> (or <em>numeral</em>) +can be written with an optional fractional part +and an optional decimal exponent, +marked by a letter '<code>e</code>' or '<code>E</code>'. +Lua also accepts hexadecimal constants, +which start with <code>0x</code> or <code>0X</code>. +Hexadecimal constants also accept an optional fractional part +plus an optional binary exponent, +marked by a letter '<code>p</code>' or '<code>P</code>'. +A numeric constant with a fractional dot or an exponent +denotes a float; +otherwise it denotes an integer. +Examples of valid integer constants are + +<pre> + 3 345 0xff 0xBEBADA +</pre><p> +Examples of valid float constants are + +<pre> + 3.0 3.1416 314.16e-2 0.31416E1 34e1 + 0x0.1E 0xA23p-4 0X1.921FB54442D18P+1 +</pre> + +<p> +A <em>comment</em> starts with a double hyphen (<code>--</code>) +anywhere outside a string. +If the text immediately after <code>--</code> is not an opening long bracket, +the comment is a <em>short comment</em>, +which runs until the end of the line. +Otherwise, it is a <em>long comment</em>, +which runs until the corresponding closing long bracket. +Long comments are frequently used to disable code temporarily. + + + + + +<h2>3.2 – <a name="3.2">Variables</a></h2> + +<p> +Variables are places that store values. +There are three kinds of variables in Lua: +global variables, local variables, and table fields. + + +<p> +A single name can denote a global variable or a local variable +(or a function's formal parameter, +which is a particular kind of local variable): + +<pre> + var ::= Name +</pre><p> +Name denotes identifiers, as defined in <a href="#3.1">§3.1</a>. + + +<p> +Any variable name is assumed to be global unless explicitly declared +as a local (see <a href="#3.3.7">§3.3.7</a>). +Local variables are <em>lexically scoped</em>: +local variables can be freely accessed by functions +defined inside their scope (see <a href="#3.5">§3.5</a>). + + +<p> +Before the first assignment to a variable, its value is <b>nil</b>. + + +<p> +Square brackets are used to index a table: + +<pre> + var ::= prefixexp ‘<b>[</b>’ exp ‘<b>]</b>’ +</pre><p> +The meaning of accesses to table fields can be changed via metatables. +An access to an indexed variable <code>t[i]</code> is equivalent to +a call <code>gettable_event(t,i)</code>. +(See <a href="#2.4">§2.4</a> for a complete description of the +<code>gettable_event</code> function. +This function is not defined or callable in Lua. +We use it here only for explanatory purposes.) + + +<p> +The syntax <code>var.Name</code> is just syntactic sugar for +<code>var["Name"]</code>: + +<pre> + var ::= prefixexp ‘<b>.</b>’ Name +</pre> + +<p> +An access to a global variable <code>x</code> +is equivalent to <code>_ENV.x</code>. +Due to the way that chunks are compiled, +<code>_ENV</code> is never a global name (see <a href="#2.2">§2.2</a>). + + + + + +<h2>3.3 – <a name="3.3">Statements</a></h2> + +<p> +Lua supports an almost conventional set of statements, +similar to those in Pascal or C. +This set includes +assignments, control structures, function calls, +and variable declarations. + + + +<h3>3.3.1 – <a name="3.3.1">Blocks</a></h3> + +<p> +A block is a list of statements, +which are executed sequentially: + +<pre> + block ::= {stat} +</pre><p> +Lua has <em>empty statements</em> +that allow you to separate statements with semicolons, +start a block with a semicolon +or write two semicolons in sequence: + +<pre> + stat ::= ‘<b>;</b>’ +</pre> + +<p> +Function calls and assignments +can start with an open parenthesis. +This possibility leads to an ambiguity in Lua's grammar. +Consider the following fragment: + +<pre> + a = b + c + (print or io.write)('done') +</pre><p> +The grammar could see it in two ways: + +<pre> + a = b + c(print or io.write)('done') + + a = b + c; (print or io.write)('done') +</pre><p> +The current parser always sees such constructions +in the first way, +interpreting the open parenthesis +as the start of the arguments to a call. +To avoid this ambiguity, +it is a good practice to always precede with a semicolon +statements that start with a parenthesis: + +<pre> + ;(print or io.write)('done') +</pre> + +<p> +A block can be explicitly delimited to produce a single statement: + +<pre> + stat ::= <b>do</b> block <b>end</b> +</pre><p> +Explicit blocks are useful +to control the scope of variable declarations. +Explicit blocks are also sometimes used to +add a <b>return</b> statement in the middle +of another block (see <a href="#3.3.4">§3.3.4</a>). + + + + + +<h3>3.3.2 – <a name="3.3.2">Chunks</a></h3> + +<p> +The unit of compilation of Lua is called a <em>chunk</em>. +Syntactically, +a chunk is simply a block: + +<pre> + chunk ::= block +</pre> + +<p> +Lua handles a chunk as the body of an anonymous function +with a variable number of arguments +(see <a href="#3.4.11">§3.4.11</a>). +As such, chunks can define local variables, +receive arguments, and return values. +Moreover, such anonymous function is compiled as in the +scope of an external local variable called <code>_ENV</code> (see <a href="#2.2">§2.2</a>). +The resulting function always has <code>_ENV</code> as its only upvalue, +even if it does not use that variable. + + +<p> +A chunk can be stored in a file or in a string inside the host program. +To execute a chunk, +Lua first <em>loads</em> it, +precompiling the chunk's code into instructions for a virtual machine, +and then Lua executes the compiled code +with an interpreter for the virtual machine. + + +<p> +Chunks can also be precompiled into binary form; +see program <code>luac</code> and function <a href="#pdf-string.dump"><code>string.dump</code></a> for details. +Programs in source and compiled forms are interchangeable; +Lua automatically detects the file type and acts accordingly (see <a href="#pdf-load"><code>load</code></a>). + + + + + +<h3>3.3.3 – <a name="3.3.3">Assignment</a></h3> + +<p> +Lua allows multiple assignments. +Therefore, the syntax for assignment +defines a list of variables on the left side +and a list of expressions on the right side. +The elements in both lists are separated by commas: + +<pre> + stat ::= varlist ‘<b>=</b>’ explist + varlist ::= var {‘<b>,</b>’ var} + explist ::= exp {‘<b>,</b>’ exp} +</pre><p> +Expressions are discussed in <a href="#3.4">§3.4</a>. + + +<p> +Before the assignment, +the list of values is <em>adjusted</em> to the length of +the list of variables. +If there are more values than needed, +the excess values are thrown away. +If there are fewer values than needed, +the list is extended with as many <b>nil</b>'s as needed. +If the list of expressions ends with a function call, +then all values returned by that call enter the list of values, +before the adjustment +(except when the call is enclosed in parentheses; see <a href="#3.4">§3.4</a>). + + +<p> +The assignment statement first evaluates all its expressions +and only then the assignments are performed. +Thus the code + +<pre> + i = 3 + i, a[i] = i+1, 20 +</pre><p> +sets <code>a[3]</code> to 20, without affecting <code>a[4]</code> +because the <code>i</code> in <code>a[i]</code> is evaluated (to 3) +before it is assigned 4. +Similarly, the line + +<pre> + x, y = y, x +</pre><p> +exchanges the values of <code>x</code> and <code>y</code>, +and + +<pre> + x, y, z = y, z, x +</pre><p> +cyclically permutes the values of <code>x</code>, <code>y</code>, and <code>z</code>. + + +<p> +The meaning of assignments to global variables +and table fields can be changed via metatables. +An assignment to an indexed variable <code>t[i] = val</code> is equivalent to +<code>settable_event(t,i,val)</code>. +(See <a href="#2.4">§2.4</a> for a complete description of the +<code>settable_event</code> function. +This function is not defined or callable in Lua. +We use it here only for explanatory purposes.) + + +<p> +An assignment to a global name <code>x = val</code> +is equivalent to the assignment +<code>_ENV.x = val</code> (see <a href="#2.2">§2.2</a>). + + + + + +<h3>3.3.4 – <a name="3.3.4">Control Structures</a></h3><p> +The control structures +<b>if</b>, <b>while</b>, and <b>repeat</b> have the usual meaning and +familiar syntax: + + + + +<pre> + stat ::= <b>while</b> exp <b>do</b> block <b>end</b> + stat ::= <b>repeat</b> block <b>until</b> exp + stat ::= <b>if</b> exp <b>then</b> block {<b>elseif</b> exp <b>then</b> block} [<b>else</b> block] <b>end</b> +</pre><p> +Lua also has a <b>for</b> statement, in two flavors (see <a href="#3.3.5">§3.3.5</a>). + + +<p> +The condition expression of a +control structure can return any value. +Both <b>false</b> and <b>nil</b> are considered false. +All values different from <b>nil</b> and <b>false</b> are considered true +(in particular, the number 0 and the empty string are also true). + + +<p> +In the <b>repeat</b>–<b>until</b> loop, +the inner block does not end at the <b>until</b> keyword, +but only after the condition. +So, the condition can refer to local variables +declared inside the loop block. + + +<p> +The <b>goto</b> statement transfers the program control to a label. +For syntactical reasons, +labels in Lua are considered statements too: + + + +<pre> + stat ::= <b>goto</b> Name + stat ::= label + label ::= ‘<b>::</b>’ Name ‘<b>::</b>’ +</pre> + +<p> +A label is visible in the entire block where it is defined, +except +inside nested blocks where a label with the same name is defined and +inside nested functions. +A goto may jump to any visible label as long as it does not +enter into the scope of a local variable. + + +<p> +Labels and empty statements are called <em>void statements</em>, +as they perform no actions. + + +<p> +The <b>break</b> statement terminates the execution of a +<b>while</b>, <b>repeat</b>, or <b>for</b> loop, +skipping to the next statement after the loop: + + +<pre> + stat ::= <b>break</b> +</pre><p> +A <b>break</b> ends the innermost enclosing loop. + + +<p> +The <b>return</b> statement is used to return values +from a function or a chunk +(which is an anonymous function). + +Functions can return more than one value, +so the syntax for the <b>return</b> statement is + +<pre> + stat ::= <b>return</b> [explist] [‘<b>;</b>’] +</pre> + +<p> +The <b>return</b> statement can only be written +as the last statement of a block. +If it is really necessary to <b>return</b> in the middle of a block, +then an explicit inner block can be used, +as in the idiom <code>do return end</code>, +because now <b>return</b> is the last statement in its (inner) block. + + + + + +<h3>3.3.5 – <a name="3.3.5">For Statement</a></h3> + +<p> + +The <b>for</b> statement has two forms: +one numeric and one generic. + + +<p> +The numeric <b>for</b> loop repeats a block of code while a +control variable runs through an arithmetic progression. +It has the following syntax: + +<pre> + stat ::= <b>for</b> Name ‘<b>=</b>’ exp ‘<b>,</b>’ exp [‘<b>,</b>’ exp] <b>do</b> block <b>end</b> +</pre><p> +The <em>block</em> is repeated for <em>name</em> starting at the value of +the first <em>exp</em>, until it passes the second <em>exp</em> by steps of the +third <em>exp</em>. +More precisely, a <b>for</b> statement like + +<pre> + for v = <em>e1</em>, <em>e2</em>, <em>e3</em> do <em>block</em> end +</pre><p> +is equivalent to the code: + +<pre> + do + local <em>var</em>, <em>limit</em>, <em>step</em> = tonumber(<em>e1</em>), tonumber(<em>e2</em>), tonumber(<em>e3</em>) + if not (<em>var</em> and <em>limit</em> and <em>step</em>) then error() end + <em>var</em> = <em>var</em> - <em>step</em> + while true do + <em>var</em> = <em>var</em> + <em>step</em> + if (<em>step</em> >= 0 and <em>var</em> > <em>limit</em>) or (<em>step</em> < 0 and <em>var</em> < <em>limit</em>) then + break + end + local v = <em>var</em> + <em>block</em> + end + end +</pre> + +<p> +Note the following: + +<ul> + +<li> +All three control expressions are evaluated only once, +before the loop starts. +They must all result in numbers. +</li> + +<li> +<code><em>var</em></code>, <code><em>limit</em></code>, and <code><em>step</em></code> are invisible variables. +The names shown here are for explanatory purposes only. +</li> + +<li> +If the third expression (the step) is absent, +then a step of 1 is used. +</li> + +<li> +You can use <b>break</b> and <b>goto</b> to exit a <b>for</b> loop. +</li> + +<li> +The loop variable <code>v</code> is local to the loop body. +If you need its value after the loop, +assign it to another variable before exiting the loop. +</li> + +</ul> + +<p> +The generic <b>for</b> statement works over functions, +called <em>iterators</em>. +On each iteration, the iterator function is called to produce a new value, +stopping when this new value is <b>nil</b>. +The generic <b>for</b> loop has the following syntax: + +<pre> + stat ::= <b>for</b> namelist <b>in</b> explist <b>do</b> block <b>end</b> + namelist ::= Name {‘<b>,</b>’ Name} +</pre><p> +A <b>for</b> statement like + +<pre> + for <em>var_1</em>, ···, <em>var_n</em> in <em>explist</em> do <em>block</em> end +</pre><p> +is equivalent to the code: + +<pre> + do + local <em>f</em>, <em>s</em>, <em>var</em> = <em>explist</em> + while true do + local <em>var_1</em>, ···, <em>var_n</em> = <em>f</em>(<em>s</em>, <em>var</em>) + if <em>var_1</em> == nil then break end + <em>var</em> = <em>var_1</em> + <em>block</em> + end + end +</pre><p> +Note the following: + +<ul> + +<li> +<code><em>explist</em></code> is evaluated only once. +Its results are an <em>iterator</em> function, +a <em>state</em>, +and an initial value for the first <em>iterator variable</em>. +</li> + +<li> +<code><em>f</em></code>, <code><em>s</em></code>, and <code><em>var</em></code> are invisible variables. +The names are here for explanatory purposes only. +</li> + +<li> +You can use <b>break</b> to exit a <b>for</b> loop. +</li> + +<li> +The loop variables <code><em>var_i</em></code> are local to the loop; +you cannot use their values after the <b>for</b> ends. +If you need these values, +then assign them to other variables before breaking or exiting the loop. +</li> + +</ul> + + + + +<h3>3.3.6 – <a name="3.3.6">Function Calls as Statements</a></h3><p> +To allow possible side-effects, +function calls can be executed as statements: + +<pre> + stat ::= functioncall +</pre><p> +In this case, all returned values are thrown away. +Function calls are explained in <a href="#3.4.10">§3.4.10</a>. + + + + + +<h3>3.3.7 – <a name="3.3.7">Local Declarations</a></h3><p> +Local variables can be declared anywhere inside a block. +The declaration can include an initial assignment: + +<pre> + stat ::= <b>local</b> namelist [‘<b>=</b>’ explist] +</pre><p> +If present, an initial assignment has the same semantics +of a multiple assignment (see <a href="#3.3.3">§3.3.3</a>). +Otherwise, all variables are initialized with <b>nil</b>. + + +<p> +A chunk is also a block (see <a href="#3.3.2">§3.3.2</a>), +and so local variables can be declared in a chunk outside any explicit block. + + +<p> +The visibility rules for local variables are explained in <a href="#3.5">§3.5</a>. + + + + + + + +<h2>3.4 – <a name="3.4">Expressions</a></h2> + +<p> +The basic expressions in Lua are the following: + +<pre> + exp ::= prefixexp + exp ::= <b>nil</b> | <b>false</b> | <b>true</b> + exp ::= Numeral + exp ::= LiteralString + exp ::= functiondef + exp ::= tableconstructor + exp ::= ‘<b>...</b>’ + exp ::= exp binop exp + exp ::= unop exp + prefixexp ::= var | functioncall | ‘<b>(</b>’ exp ‘<b>)</b>’ +</pre> + +<p> +Numerals and literal strings are

href="#3.4.10">§3.4.10</a>; +table constructors are explained in <a href="#3.4.9">§3.4.9</a>. +Vararg expressions, +denoted by three dots ('<code>...</code>'), can only be used when +directly inside a vararg function; +they are explained in <a href="#3.4.11">§3.4.11</a>. + + +<p> +Binary operators comprise arithmetic operators (see <a href="#3.4.1">§3.4.1</a>), +bitwise operators (see <a href="#3.4.2">§3.4.2</a>), +relational operators (see <a href="#3.4.4">§3.4.4</a>), logical operators (see <a href="#3.4.5">§3.4.5</a>), +and the concatenation operator (see <a href="#3.4.6">§3.4.6</a>). +Unary operators comprise the unary minus (see <a href="#3.4.1">§3.4.1</a>), +the unary bitwise not (see <a href="#3.4.2">§3.4.2</a>), +the unary logical <b>not</b> (see <a href="#3.4.5">§3.4.5</a>), +and the unary <em>length operator</em> (see <a href="#3.4.7">§3.4.7</a>). + + +<p> +Both function calls and vararg expressions can result in multiple values. +If a function call is used as a statement (see <a href="#3.3.6">§3.3.6</a>), +then its return list is adjusted to zero elements, +thus discarding all returned values. +If an expression is used as the last (or the only) element +of a list of expressions, +then no adjustment is made +(unless the expression is enclosed in parentheses). +In all other contexts, +Lua adjusts the result list to one element, +either discarding all values except the first one +or adding a single <b>nil</b> if there are no values. + + +<p> +Here are some examples: + +<pre> + f() -- adjusted to 0 results + g(f(), x) -- f() is adjusted to 1 result + g(x, f()) -- g gets x plus all results from f() + a,b,c = f(), x -- f() is adjusted to 1 result (c gets nil) + a,b = ... -- a gets the first vararg parameter, b gets + -- the second (both a and b can get nil if there + -- is no corresponding vararg parameter) + + a,b,c = x, f() -- f() is adjusted to 2 results + a,b,c = f() -- f() is adjusted to 3 results + return f() -- returns all results from f() + return ... -- returns all received vararg parameters + return x,y,f() -- returns x, y, and all results from f() + {f()} -- creates a list with all results from f() + {...} -- creates a list with all vararg parameters + {f(), nil} -- f() is adjusted to 1 result +</pre> + +<p> +Any expression enclosed in parentheses always results in only one value. +Thus, +<code>(f(x,y,z))</code> is always a single value, +even if <code>f</code> returns several values. +(The value of <code>(f(x,y,z))</code> is the first value returned by <code>f</code> +or <b>nil</b> if <code>f</code> does not return any values.) + + + +<h3>3.4.1 – <a name="3.4.1">Arithmetic Operators</a></h3><p> +Lua supports the following arithmetic operators: + +<ul> +<li><b><code>+</code>:

and float division, +the arithmetic operators work as follows: +If both operands are integers, +the operation is performed over integers and the result is an integer. +Otherwise, if both operands are numbers +or strings that can be converted to +numbers (see <a href="#3.4.3">§3.4.3</a>), +then they are converted to floats, +the operation is performed following the usual rules +for floating-point arithmetic +(usually the IEEE 754 standard), +and the result is a float. + + +<p> +Exponentiation and float division (<code>/</code>) +always convert their operands to floats +and the result is always a float. +Exponentiation uses the ISO C function <code>pow</code>, +so that it works for non-integer exponents too. + + +<p> +Floor division (<code>//</code>) is a division +that rounds the quotient towards minus infinite, +that is, the floor of the division of its operands. + + +<p> +Modulo is defined as the remainder of a division +that rounds the quotient towards minus infinite (floor division). + + +<p> +In case of overflows in integer arithmetic, +all operations <em>wrap around</em>, +according to the usual rules of two-complement arithmetic. +(In other words, +they return the unique representable integer +that is equal modulo <em>2<sup>64</sup></em> to the mathematical result.) + + + +<h3>3.4.2 – <a name="3.4.2">Bitwise Operators</a></h3><p> +Lua supports the following bitwise operators: + +<ul> +<li><b><code>&</code>: </b>bitwise and</li> +<li><b><code>|</code>: </b>bitwise or</li> +<li><b><code>~</code>: </b>bitwise exclusive or</li> +<li><b><code>>></code>:

a float; +this is called the <em>usual rule</em>. +The C API also converts both integers to floats and +floats to integers, as needed. +Moreover, string concatenation accepts numbers as arguments, +besides strings. + + +<p> +Lua also converts strings to numbers, +whenever a number is expected. + + +<p> +In a conversion from integer to float, +if the integer value has an exact representation as a float, +that is the result. +Otherwise, +the conversion gets the nearest higher or +the nearest lower representable value. +This kind of conversion never fails. + + +<p> +The conversion from float to integer +checks whether the float has an exact representation as an integer +(that is, the float has an integral value and +it is in the range of integer representation). +If it does, that representation is the result. +Otherwise, the conversion fails. + + +<p> +The conversion from strings to numbers goes as follows: +First, the string is converted to an integer or a float, +following its syntax and the rules of the Lua lexer. +(The string may have also leading and trailing spaces and a sign.) +Then, the resulting number is converted to the required type +(float or integer) according to the previous rules. + + +<p> +The conversion from numbers to strings uses a +non-specified human-readable format. +For complete control over how numbers are converted to strings, +use the <code>format</code> function from the string library +(see <a href="#pdf-string.format"><code>string.format</code></a>). + + + + + +<h3>3.4.4 – <a name="3.4.4">Relational Operators</a></h3><p> +Lua supports the following relational operators: + +<ul> +<li><b><code>==</code>: </b>equality</li> +<li><b><code>~=</code>: </b>inequality</li> +<li><b><code><</code>: </b>less than</li> +<li><b><code>></code>: </b>greater than</li> +<li><b><code><=</code>: </b>less or equal</li> +<li><b><code>>=</code>: </b>greater or equal</li> +</ul><p> +These operators always result in <b>false</b> or <b>true</b>. + + +<p> +Equality (<code>==</code>) first compares the type of its operands. +If the types are different, then the result is <b>false</b>. +Otherwise, the values of the operands are compared. +Strings are compared in the obvious way. +Numbers follow the usual rule for binary operations: +if both operands are integers, +they are compared as integers; +otherwise, they are converted to floats +and compared as such. + + +<p> +Tables, userdata, and threads +are compared by reference: +two objects are considered equal only if they are the same object. +Every time you create a new object +(a table, userdata, or thread), +this new object is different from any previously existing object. +Closures with the same reference are always equal. +Closures with any detectable difference +(different behavior, different definition) are always different. + + +<p> +You can change the way that Lua compares tables and userdata +by using the "eq" metamethod (see <a href="#2.4">§2.4</a>). + + +<p> +Equality comparisons do not convert strings to numbers +or vice versa. +Thus, <code>"0"==0</code> evaluates to <b>false</b>, +and <code>t[0]</code> and <code>t["0"]</code> denote different +entries in a table. + + +<p> +The operator <code>~=</code> is exactly the negation of equality (<code>==</code>). + + +<p> +The order operators work as follows. +If both arguments are numbers, +then they are compared following +the usual rule for binary operations. +Otherwise, if both arguments are strings, +then their values are compared according to the current locale. +Otherwise, Lua tries to call the "lt" or the "le" +metamethod (see <a href="#2.4">§2.4</a>). +A comparison <code>a > b</code> is translated to <code>b < a</code> +and <code>a >= b</code> is translated to <code>b <= a</code>. + + + + + +<h3>3.4.5 – <a name="3.4.5">Logical Operators</a></h3><p> +The logical operators in Lua are +<b>and</b>, <b>or</b>, and <b>not</b>. +Like the control structures (see <a href="#3.3.4">§3.3.4</a>), +all logical operators consider both <b>false</b> and <b>nil</b> as false +and anything else as true. + + +<p> +The negation operator <b>not</b> always returns <b>false</b> or <b>true</b>. +The conjunction operator <b>and</b> returns its first argument +if this value is <b>false</b> or <b>nil</b>; +otherwise, <b>and</b> returns its second argument. +The disjunction operator <b>or</b> returns its first argument +if this value is different from <b>nil</b> and <b>false</b>; +otherwise, <b>or</b> returns its second argument. +Both <b>and</b> and <b>or</b> use short-circuit evaluation; +that is, +the second operand is evaluated only if necessary. +Here are some examples: + +<pre> + 10 or 20 --> 10 + 10 or error() --> 10 + nil or "a" --> "a" + nil and 10 --> nil + false and error() --> false + false and nil --> false + false or nil --> nil + 10 and 20 --> 20 +</pre><p> +(In this manual, +<code>--></code> indicates the result of the preceding expression.) + + + + + +<h3>3.4.6 – <a name="3.4.6">Concatenation</a></h3><p> +The string concatenation operator in Lua is +denoted by two dots ('<code>..</code>'). +If both operands are strings or numbers, then they are converted to +strings according to the rules described in <a href="#3.4.3">§3.4.3</a>. +Otherwise, the <code>__concat</code> metamethod is called (see <a href="#2.4">§2.4</a>). + + + + + +<h3>3.4.7 – <a name="3.4.7">The Length Operator</a></h3> + +<p> +The length operator is denoted by the unary prefix operator <code>#</code>. +The length of a string is its number of bytes +(that is, the usual meaning of string length when each +character is one byte). + + +<p> +A program can modify the behavior of the length operator for +any value but strings through the <code>__len</code> metamethod (see <a href="#2.4">§2.4</a>). + + +<p> +Unless a <code>__len</code> metamethod is given, +the length of a table <code>t</code> is only defined if the +table is a <em>sequence</em>, +that is, +the set of its positive numeric keys is equal to <em>{1..n}</em> +for some non-negative integer <em>n</em>. +In that case, <em>n</em> is its length. +Note that a table like + +<pre> + {10, 20, nil, 40} +</pre><p> +is not a sequence, because it has the key <code>4</code> +but does not have the key <code>3</code>. +(So, there is no <em>n</em> such that the set <em>{1..n}</em> is equal +to the set of positive numeric keys of that table.) +Note, however, that non-numeric keys do not interfere +with whether a table is a sequence. + + + + + +<h3>3.4.8 – <a name="3.4.8">Precedence</a></h3><p> +Operator precedence in Lua follows the table below, +from lower to higher priority: + +<pre> + or + and + < > <= >= ~= == + | + ~ + & + << >> + .. + + - + * / // % + unary operators (not # - ~) + ^ +</pre><p> +As usual, +you can use parentheses to change the precedences of an expression. +The concatenation ('<code>..</code>') and exponentiation ('<code>^</code>') +operators are right associative. +All other binary operators are left associative. + + + + + +<h3>3.4.9 – <a name="3.4.9">Table Constructors</a></h3><p> +Table constructors are expressions that create tables. +Every time a constructor is evaluated, a new table is created. +A constructor can be used to create an empty table +or to create a table and initialize some of its fields. +The general syntax for constructors is + +<pre> + tableconstructor ::= ‘<b>{</b>’ [fieldlist] ‘<b>}</b>’ + fieldlist ::= field {fieldsep field} [fieldsep] + field ::= ‘<b>[</b>’ exp ‘<b>]</b>’ ‘<b>=</b>’ exp | Name ‘<b>=</b>’ exp | exp + fieldsep ::= ‘<b>,</b>’ | ‘<b>;</b>’ +</pre> + +<p> +Each field of the form <code>[exp1] = exp2</code> adds to the new table an entry +with key <code>exp1</code> and value <code>exp2</code>. +A field of the form <code>name = exp</code> is equivalent to +<code>["name"] = exp</code>. +Finally, fields of the form <code>exp</code> are equivalent to +<code>[i] = exp</code>, where <code>i</code> are consecutive integers +starting with 1. +Fields in the other formats do not affect this counting. +For example, + +<pre> + a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 } +</pre><p> +is equivalent to + +<pre> + do + local t = {} + t[f(1)] = g + t[1] = "x" -- 1st exp + t[2] = "y" -- 2nd exp + t.x = 1 -- t["x"] = 1 + t[3] = f(x) -- 3rd exp + t[30] = 23 + t[4] = 45 -- 4th exp + a = t + end +</pre> + +<p> +The order of the assignments in a constructor is undefined. +(This order would be relevant only when there are repeated keys.) + + +<p> +If the last field in the list has the form <code>exp</code> +and the expression is a function call or a vararg expression, +then all values returned by this expression enter the list consecutively +(see <a href="#3.4.10">§3.4.10</a>). + + +<p> +The field list can have an optional trailing separator, +as a convenience for machine-generated code. + + + + + +<h3>3.4.10 – <a name="3.4.10">Function Calls</a></h3><p> +A function call in Lua has the following syntax: + +<pre> + functioncall ::= prefixexp args +</pre><p> +In a function call, +first prefixexp and args are evaluated. +If the value of prefixexp has type <em>function</em>, +then this function is called +with the given arguments. +Otherwise, the prefixexp "call" metamethod is called, +having as first parameter the value of prefixexp, +followed by the original call arguments +(see <a href="#2.4">§2.4</a>). + + +<p> +The form + +<pre> + functioncall ::= prefixexp ‘<b>:</b>’ Name args +</pre><p> +can be used to call "methods". +A call <code>v:name(<em>args</em>)</code> +is syntactic sugar for <code>v.name(v,<em>args</em>)</code>, +except that <code>v</code> is evaluated only once. + + +<p> +Arguments have the following syntax: + +<pre> + args ::= ‘<b>(</b>’ [explist] ‘<b>)</b>’ + args ::= tableconstructor + args ::= LiteralString +</pre><p> +All argument expressions are evaluated before the call. +A call of the form <code>f{<em>fields</em>}</code> is +syntactic sugar for <code>f({<em>fields</em>})</code>; +that is, the argument list is a single new table. +A call of the form <code>f'<em>string</em>'</code> +(or <code>f"<em>string</em>"</code> or <code>f[[<em>string</em>]]</code>) +is syntactic sugar for <code>f('<em>string</em>')</code>; +that is, the argument list is a single literal string. + + +<p> +A call of the form <code>return <em>functioncall</em></code> is called +a <em>tail call</em>. +Lua implements <em>proper tail calls</em> +(or <em>proper tail recursion</em>): +in a tail call, +the called function reuses the stack entry of the calling function. +Therefore, there is no limit on the number of nested tail calls that +a program can execute. +However, a tail call erases any debug information about the +calling function. +Note that a tail call only happens with a particular syntax, +where the <b>return</b> has one single function call as argument; +this syntax makes the calling function return exactly +the returns of the called function. +So, none of the following examples are tail calls: + +<pre> + return (f(x)) -- results adjusted to 1 + return 2 * f(x) + return x, f(x) -- additional results + f(x); return -- results discarded + return x or f(x) -- results adjusted to 1 +</pre> + + + + +<h3>3.4.11 – <a name="3.4.11">Function Definitions</a></h3> + +<p> +The syntax for function definition is + +<pre> + functiondef ::= <b>function</b> funcbody + funcbody ::= ‘<b>(</b>’ [parlist] ‘<b>)</b>’ block <b>end</b> +</pre> + +<p> +The following syntactic sugar simplifies function definitions: + +<pre> + stat ::= <b>function</b> funcname funcbody + stat ::= <b>local</b> <b>function</b> Name funcbody + funcname ::= Name {‘<b>.</b>’ Name} [‘<b>:</b>’ Name] +</pre><p> +The statement + +<pre> + function f () <em>body</em> end +</pre><p> +translates to + +<pre> + f = function () <em>body</em> end +</pre><p> +The statement + +<pre> + function t.a.b.c.f () <em>body</em> end +</pre><p> +translates to + +<pre> + t.a.b.c.f = function () <em>body</em> end +</pre><p> +The statement + +<pre> + local function f () <em>body</em> end +</pre><p> +translates to + +<pre> + local f; f = function () <em>body</em> end +</pre><p> +not to + +<pre> + local f = function () <em>body</em> end +</pre><p> +(This only makes a difference when the body of the function +contains references to <code>f</code>.) + + +<p> +A function definition is an executable expression, +whose value has type <em>function</em>. +When Lua precompiles a chunk, +all its function bodies are precompiled too. +Then, whenever Lua executes the function definition, +the function is <em>instantiated</em> (or <em>closed</em>). +This function instance (or <em>closure</em>) +is the final value of the expression. + + +<p> +Parameters act as local variables that are +initialized with the argument values: + +<pre> + parlist ::= namelist [‘<b>,</b>’ ‘<b>...</b>’] | ‘<b>...</b>’ +</pre><p> +When a function is called, +the list of arguments is adjusted to +the length of the list of parameters, +unless the function is a <em>vararg function</em>, +which is indicated by three dots ('<code>...</code>') +at the end of its parameter list. +A vararg function does not adjust its argument list; +instead, it collects all extra arguments and supplies them +to the function through a <em>vararg expression</em>, +which is also written as three dots. +The value of this expression is a list of all actual extra arguments, +similar to a function with multiple results. +If a vararg expression is used inside another expression +or in the middle of a list of expressions, +then its return list is adjusted to one element. +If the expression is used as the last element of a list of expressions, +then no adjustment is made +(unless that last expression is enclosed in parentheses). + + +<p> +As an example, consider the following definitions: + +<pre> + function f(a, b) end + function g(a, b, ...) end + function r() return 1,2,3 end +</pre><p> +Then, we have the following mapping from arguments to parameters and +to the vararg expression: + +<pre> + CALL PARAMETERS + + f(3) a=3, b=nil + f(3, 4) a=3, b=4 + f(3, 4, 5) a=3, b=4 + f(r(), 10) a=1, b=10 + f(r()) a=1, b=2 + + g(3) a=3, b=nil, ... --> (nothing) + g(3, 4) a=3, b=4, ... --> (nothing) + g(3, 4, 5, 8) a=3, b=4, ... --> 5 8 + g(5, r()) a=5, b=1, ... --> 2 3 +</pre> + +<p> +Results are returned using the <b>return</b> statement (see <a href="#3.3.4">§3.3.4</a>). +If control reaches the end of a function +without encountering a <b>return</b> statement, +then the function returns with no results. + + +<p> + +There is a system-dependent limit on the number of values +that a function may return. +This limit is guaranteed to be larger than 1000. + + +<p> +The <em>colon</em> syntax +is used for defining <em>methods</em>, +that is, functions that have an implicit extra parameter <code>self</code>. +Thus, the statement + +<pre> + function t.a.b.c:f (<em>params</em>) <em>body</em> end +</pre><p> +is syntactic sugar for + +<pre> + t.a.b.c.f = function (self, <em>params</em>) <em>body</em> end +</pre> + + + + + + +<h2>3.5 – <a name="3.5">Visibility Rules</a></h2> + +<p> + +Lua is a lexically scoped language. +The scope of a local variable begins at the first statement after +its declaration and lasts until the last non-void statement +of the innermost block that includes the declaration. +Consider the following example: + +<pre> + x = 10 -- global variable + do -- new block + local x = x -- new 'x', with value 10 + print(x) --> 10 + x = x+1 + do -- another block + local x = x+1 -- another 'x' + print(x) --> 12 + end + print(x) --> 11 + end + print(x) --> 10 (the global one) +</pre> + +<p> +Notice that, in a declaration like <code>local x = x</code>, +the new <code>x</code> being declared is not in scope yet, +and so the second <code>x</code> refers to the outside variable. + + +<p> +Because of the lexical scoping rules, +local variables can be freely accessed by functions +defined inside their scope. +A local variable used by an inner function is called +an <em>upvalue</em>, or <em>external local variable</em>, +inside the inner function. + + +<p> +Notice that each execution of a <b>local</b> statement +defines new local variables. +Consider the following example: + +<pre> + a = {} + local x = 20 + for i=1,10 do + local y = 0 + a[i] = function () y=y+1; return x+y end + end +</pre><p> +The loop creates ten closures +(that is, ten instances of the anonymous function). +Each of these closures uses a different <code>y</code> variable, +while all of them share the same <code>x</code>. + + + + + +<h1>4 – <a name="4">The Application Program Interface</a></h1> + +<p> + +This section describes the C API for Lua, that is, +the set of C functions available to the host program to communicate +with Lua. +All API functions and related types and constants +are declared in the header file <a name="pdf-lua.h"><code>lua.h</code></a>. + + +<p> +Even when we use the term "function", +any facility in the API may be provided as a macro instead. +Except where stated otherwise, +all such macros use each of their arguments exactly once +(except for the first argument, which is always a Lua state), +and so do not generate any hidden side-effects. + + +<p> +As in most C libraries, +the Lua API functions do not check their arguments for validity or consistency. +However, you can change this behavior by compiling Lua +with the macro <a name="pdf-LUA_USE_APICHECK"><code>LUA_USE_APICHECK</code></a> defined. + + + +<h2>4.1 – <a name="4.1">The Stack</a></h2> + +<p> +Lua uses a <em>virtual stack</em> to pass values to and from C. +Each element in this stack represents a Lua value +(<b>nil</b>, number, string, etc.). + + +<p> +Whenever Lua calls C, the called function gets a new stack, +which is independent of previous stacks and of stacks of +C functions that are still active. +This stack initially contains any arguments to the C function +and it is where the C function pushes its results +to be returned to the caller (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>). + + +<p> +For convenience, +most query operations in the API do not follow a strict stack discipline. +Instead, they can refer to any element in the stack +by using an <em>index</em>: +A positive index represents an absolute stack position +(starting at 1); +a negative index represents an offset relative to the top of the stack. +More specifically, if the stack has <em>n</em> elements, +then index 1 represents the first element +(that is, the element that was pushed onto the stack first) +and +index <em>n</em> represents the last element; +index -1 also represents the last element +(that is, the element at the top) +and index <em>-n</em> represents the first element. + + + + + +<h2>4.2 – <a name="4.2">Stack Size</a></h2> + +<p> +When you interact with the Lua API, +you are responsible for ensuring consistency. +In particular, +<em>you are responsible for controlling stack overflow</em>. +You can use the function <a href="#lua_checkstack"><code>lua_checkstack</code></a> +to ensure that the stack has enough space for pushing new elements. + + +<p> +Whenever Lua calls C, +it ensures that the stack has space for +at least <a name="pdf-LUA_MINSTACK"><code>LUA_MINSTACK</code></a> extra slots. +<code>LUA_MINSTACK</code> is defined as 20, +so that usually you do not have to worry about stack space +unless your code has loops pushing elements onto the stack. + + +<p> +When you call a Lua function +without a fixed number of results (see <a href="#lua_call"><code>lua_call</code></a>), +Lua ensures that the stack has enough space for all results, +but it does not ensure any extra space. +So, before pushing anything in the stack after such a call +you should use <a href="#lua_checkstack"><code>lua_checkstack</code></a>. + + + + + +<h2>4.3 – <a name="4.3">Valid and Acceptable Indices</a></h2> + +<p> +Any function in the API that receives stack indices +works only with <em>valid indices</em> or <em>acceptable indices</em>. + + +<p> +A <em>valid index</em> is an index that refers to a +real position within the stack, that is, +its position lies between 1 and the stack top +(<code>1 ≤ abs(index) ≤ top</code>). + +Usually, functions that can modify the value at an index +require valid indices. + + +<p> +Unless otherwise noted, +any function that accepts valid indices also accepts <em>pseudo-indices</em>, +which represent some Lua values that are accessible to C code +but which are not in the stack. +Pseudo-indices are used to access the registry +and the upvalues of a C function (see <a href="#4.4">§4.4</a>). + + +<p> +Functions that do not need a specific stack position, +but only a value in the stack (e.g., query functions), +can be called with acceptable indices. +An <em>acceptable index</em> can be any valid index, +including the pseudo-indices, +but it also can be any positive index after the stack top +within the space allocated for the stack, +that is, indices up to the stack size. +(Note that 0 is never an acceptable index.) +Except when noted otherwise, +functions in the API work with acceptable indices. + + +<p> +Acceptable indices serve to avoid extra tests +against the stack top when querying the stack. +For instance, a C function can query its third argument +without the need to first check whether there is a third argument, +that is, without the need to check whether 3 is a valid index. + + +<p> +For functions that can be called with acceptable indices, +any non-valid index is treated as if it +contains a value of a virtual type <a name="pdf-LUA_TNONE"><code>LUA_TNONE</code></a>, +which behaves like a nil value. + + + + + +<h2>4.4 – <a name="4.4">C Closures</a></h2> + +<p> +When a C function is created, +it is possible to associate some values with it, +thus creating a <em>C closure</em> +(see <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>); +these values are called <em>upvalues</em> and are +accessible to the function whenever it is called. + + +<p> +Whenever a C function is called, +its upvalues are located at specific pseudo-indices. +These pseudo-indices are produced by the macro +<a href="#lua_upvalueindex"><code>lua_upvalueindex</code></a>. +The first value associated with a function is at position +<code>lua_upvalueindex(1)</code>, and so on. +Any access to <code>lua_upvalueindex(<em>n</em>)</code>, +where <em>n</em> is greater than the number of upvalues of the +current function (but not greater than 256), +produces an acceptable but invalid index. + + + + + +<h2>4.5 – <a name="4.5">Registry</a></h2> + +<p> +Lua provides a <em>registry</em>, +a predefined table that can be used by any C code to +store whatever Lua values it needs to store. +The registry table is always located at pseudo-index +<a name="pdf-LUA_REGISTRYINDEX"><code>LUA_REGISTRYINDEX</code></a>, +which is a valid index. +Any C library can store data into this table, +but it must take care to choose keys +that are different from those used +by other libraries, to avoid collisions. +Typically, you should use as key a string containing your library name, +or a light userdata with the address of a C object in your code, +or any Lua object created by your code. +As with variable names, +string keys starting with an underscore followed by +uppercase letters are reserved for Lua. + + +<p> +The integer keys in the registry are used +by the reference mechanism (see <a href="#luaL_ref"><code>luaL_ref</code></a>) +and by some predefined values. +Therefore, integer keys must not be used for other purposes. + + +<p> +When you create a new Lua state, +its registry comes with some predefined values. +These predefined values are indexed with integer keys +defined as constants in <code>lua.h</code>. +The following constants are defined: + +<ul> +<li><b><a name="pdf-LUA_RIDX_MAINTHREAD"><code>LUA_RIDX_MAINTHREAD</code></a>: </b> At this index the registry has +the main thread of the state. +(The main thread is the one created together with the state.) +</li> + +<li><b><a name="pdf-LUA_RIDX_GLOBALS"><code>LUA_RIDX_GLOBALS</code></a>: </b> At this index the registry has +the global environment. +</li> +</ul> + + + + +<h2>4.6 – <a name="4.6">Error Handling in C</a></h2> + +<p> +Internally, Lua uses the C <code>longjmp</code> facility to handle errors. +(Lua will use exceptions if you compile it as C++; +search for <code>LUAI_THROW</code> in the source code for details.) +When Lua faces any error +(such as a memory allocation error, type errors, syntax errors, +and runtime errors) +it <em>raises</em> an error; +that is, it does a long jump. +A <em>protected environment</em> uses <code>setjmp</code> +to set a recovery point; +any error jumps to the most recent active recovery point. + + +<p> +If an error happens outside any protected environment, +Lua calls a <em>panic function</em> (see <a href="#lua_atpanic"><code>lua_atpanic</code></a>) +and then calls <code>abort</code>, +thus exiting the host application. +Your panic function can avoid this exit by +never returning +(e.g., doing a long jump to your own recovery point outside Lua). + + +<p> +The panic function runs as if it were a message handler (see <a href="#2.3">§2.3</a>); +in particular, the error message is at the top of the stack. +However, there is no guarantee about stack space. +To push anything on the stack, +the panic function must first check the available space (see <a href="#4.2">§4.2</a>). + + +<p> +Most functions in the API can raise an error, +for instance due to a memory allocation error. +The documentation for each function indicates whether +it can raise errors. + + +<p> +Inside a C function you can raise an error by calling <a href="#lua_error"><code>lua_error</code></a>. + + + + + +<h2>4.7 – <a name="4.7">Handling Yields in C</a></h2> + +<p> +Internally, Lua uses the C <code>longjmp</code> facility to yield a coroutine. +Therefore, if a C function <code>foo</code> calls an API function +and this API function yields +(directly or indirectly by calling another function that yields), +Lua cannot return to <code>foo</code> any more, +because the <code>longjmp</code> removes its frame from the C stack. + + +<p> +To avoid this kind of problem, +Lua raises an error whenever it tries to yield across an API call, +except for three functions: +<a href="#lua_yieldk"><code>lua_yieldk</code></a>, <a href="#lua_callk"><code>lua_callk</code></a>, and <a href="#lua_pcallk"><code>lua_pcallk</code></a>. +All those functions receive a <em>continuation function</em> +(as a parameter named <code>k</code>) to continue execution after a yield. + + +<p> +We need to set some terminology to explain continuations. +We have a C function called from Lua which we will call +the <em>original function</em>. +This original function then calls one of those three functions in the C API, +which we will call the <em>callee function</em>, +that then yields the current thread. +(This can happen when the callee function is <a href="#lua_yieldk"><code>lua_yieldk</code></a>, +or when the callee function is either <a href="#lua_callk"><code>lua_callk</code></a> or <a href="#lua_pcallk"><code>lua_pcallk</code></a> +and the function called by them yields.) + + +<p> +Suppose the running thread yields while executing the callee function. +After the thread resumes, +it eventually will finish running the callee function. +However, +the callee function cannot return to the original function, +because its frame in the C stack was destroyed by the yield. +Instead, Lua calls a <em>continuation function</em>, +which was given as an argument to the callee function. +As the name implies, +the continuation function should continue the task +of the original function. + + +<p> +As an illustration, consider the following

+ } + + int original_function (lua_State *L) { + ... /* code 1 */ + return k(L, lua_pcall(L, n, m, h), ctx); + } +</pre><p> +In the above code, +the new function <code>k</code> is a +<em>continuation function</em> (with type <a href="#lua_KFunction"><code>lua_KFunction</code></a>), +which should do all the work that the original function +was doing after calling <a

interrupted in some way +(errors or yielding), +so we rewrite the code as here, +replacing <a href="#lua_pcall"><code>lua_pcall</code></a> by <a href="#lua_pcallk"><code>lua_pcallk</code></a>: + +<pre> + int original_function (lua_State *L) { + ... /* code 1 */ + return k(L, lua_pcallk(L, n, m, h, ctx2, k), ctx1); + } +</pre><p> +Note the external, explicit call to the continuation: +Lua will call the continuation only if needed, that is, +in case of errors or resuming after a yield. +If the called function returns normally without ever yielding, +<a href="#lua_pcallk"><code>lua_pcallk</code></a> (and <a href="#lua_callk"><code>lua_callk</code></a>) will also return normally. +(Of course, instead of calling the continuation in that case, +you can do the equivalent work directly inside the original function.) + + +<p> +Besides the Lua state, +the continuation function has two other parameters: +the final status of the call plus the context value (<code>ctx</code>) that +was passed originally to <a href="#lua_pcallk"><code>lua_pcallk</code></a>. +(Lua does not use this context value; +it only passes this value from the original function to the +continuation function.) +For <a href="#lua_pcallk"><code>lua_pcallk</code></a>, +the status is the same value that would be returned by <a href="#lua_pcallk"><code>lua_pcallk</code></a>, +except that it is <a href="#pdf-LUA_YIELD"><code>LUA_YIELD</code></a> when being executed after a yield +(instead of <a href="#pdf-LUA_OK"><code>LUA_OK</code></a>). +For <a href="#lua_yieldk"><code>lua_yieldk</code></a> and <a href="#lua_callk"><code>lua_callk</code></a>, +the status is always <a href="#pdf-LUA_YIELD"><code>LUA_YIELD</code></a> when Lua calls the continuation. +(For these two functions, +Lua will not call the continuation in case of errors, +because they do not handle errors.) +Similarly, when using <a href="#lua_callk"><code>lua_callk</code></a>, +you should call the continuation function +with <a href="#pdf-LUA_OK"><code>LUA_OK</code></a> as the status. +(For <a href="#lua_yieldk"><code>lua_yieldk</code></a>, there is not much point in calling +directly the continuation function, +because <a href="#lua_yieldk"><code>lua_yieldk</code></a> usually does not return.) + + +<p> +Lua treats the continuation function as if it were the original function. +The continuation function receives the same Lua stack +from the original function, +in the same state it would be if the callee function had returned. +(For instance, +after a <a href="#lua_callk"><code>lua_callk</code></a> the function and its arguments are +removed from the stack and replaced by the results from the call.) +It also has the same upvalues. +Whatever it returns is handled by Lua as if it were the return +of the original function. + + + + + +<h2>4.8 – <a name="4.8">Functions and

situation; +an interrogation mark '<code>?</code>' means that +we cannot know how many elements the function pops/pushes +by looking only at its arguments +(e.g., they may depend on what is on the

for specific modules +(see <a href="#pdf-require"><code>require</code></a>). + + +<p> +This variable is only a reference to the real table; +assignments to this variable do not change the +table used by <a href="#pdf-require"><code>require</code></a>. + + + + +<p> +<hr><h3><a name="pdf-package.searchers"><code>package.searchers</code></a></h3> + + +<p> +A table used by <a href="#pdf-require"><code>require</code></a> to control how to load modules. + + +<p> +Each entry in this table is a <em>searcher function</em>. +When looking for a module, +<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order, +with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its +sole parameter. +The function can return another function (the module <em>loader</em>) +plus an extra value that will be passed to that loader, +or a string explaining why it did not find that module +(or <b>nil</b> if it has nothing to say). + + +<p> +Lua initializes this table with four searcher functions. + + +<p> +The first searcher simply looks for a loader in the +<a href="#pdf-package.preload"><code>package.preload</code></a> table. + + +<p> +The second searcher looks for a loader as a Lua library, +using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>. +The search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>. + + +<p> +The third searcher looks for a loader as a C library, +using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>. +Again, +the search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>. +For instance, +if the C path is the string + +<pre> + "./?.so;./?.dll;/usr/local/?/init.so" +</pre><p> +the searcher for module <code>foo</code> +will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>, +and <code>/usr/local/foo/init.so</code>, in that order. +Once it finds a C library, +this searcher first uses a dynamic link facility to link the +application with the library. +Then it tries to find a C function inside the library to +be used as the loader. +The name of this C function is the string "<code>luaopen_</code>" +concatenated with a copy of the module name where each dot +is replaced by an underscore. +Moreover, if the module name has a hyphen, +its suffix after (and including) the first hyphen is removed. +For instance, if the module name is <code>a.b.c-v2.1</code>, +the function name will be <code>luaopen_a_b_c</code>. + + +<p> +The fourth searcher tries an <em>all-in-one loader</em>. +It searches the C path for a library for +the root name of the given module. +For instance, when requiring <code>a.b.c</code>, +it will search for a C library for <code>a</code>. +If found, it looks into it for an open function for +the submodule; +in our example, that would be <code>luaopen_a_b_c</code>. +With this facility, a package can pack several C submodules +into one single library, +with each submodule keeping its original open function. + + +<p> +All searchers except the first one (preload) return as the extra value +the file name where the module was found, +as returned by <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>. +The first searcher returns no extra value. + + + + +<p> +<hr><h3><a

<code>name</code> +wherein all occurrences of <code>sep</code> +(a dot, by default) +were replaced by <code>rep</code> +(the system's directory separator, by default), +and then tries to open the

Manipulation</a></h2> + +<p> +This library provides generic functions for string manipulation, +such as finding and extracting substrings, and pattern matching. +When indexing a string in Lua, the first character is at position 1 +(not at 0, as in C). +Indices are allowed to be negative and are interpreted as indexing backwards, +from the end of the string. +Thus, the last character is at position -1, and so on. + + +<p> +The string library provides all its functions inside the table +<a name="pdf-string"><code>string</code></a>. +It also sets a metatable for strings +where the <code>__index</code> field points to the <code>string</code> table. +Therefore, you can use the string functions in object-oriented style. +For instance, <code>string.byte(s,i)</code> +can be written as <code>s:byte(i)</code>. + + +<p> +The string library assumes one-byte character encodings. + + +<p> +<hr><h3><a name="pdf-string.byte"><code>string.byte (s [, i [, j]])</code></a></h3> +Returns the internal numerical codes of the characters <code>s[i]</code>, +<code>s[i+1]</code>, ..., <code>s[j]</code>. +The default value for <code>i</code> is 1; +the default value for <code>j</code> is <code>i</code>. +These indices are corrected +following the same rules of function <a href="#pdf-string.sub"><code>string.sub</code></a>. + + +<p> +Numerical codes are not necessarily portable across platforms. + + + + +<p> +<hr><h3><a name="pdf-string.char"><code>string.char (···)</code></a></h3> +Receives zero or more integers. +Returns a string with length equal to the number of arguments, +in which each character has the internal numerical code equal +to its corresponding argument. + + +<p> +Numerical codes are not necessarily portable across platforms. + + + + +<p> +<hr><h3><a name="pdf-string.dump"><code>string.dump (function [, strip])</code></a></h3> + + +<p> +Returns a string containing a binary representation +(a <em>binary chunk</em>) +of the given function, +so that a later <a href="#pdf-load"><code>load</code></a> on this string returns +a copy of the function (but with new upvalues). +If <code>strip</code> is a true value, +the binary representation is created without debug information +about the function +(local variable names, lines, etc.). + + +<p> +Functions with upvalues have only their number of upvalues saved. +When (re)loaded, +those upvalues receive fresh instances containing <b>nil</b>. +(You can use the debug library to serialize +and reload the upvalues of a function +in a way adequate to your needs.) + + + + +<p> +<hr><h3><a

<code>s</code>. +If it finds a match, then <code>find</code> returns the indices of <code>s</code> +where this occurrence starts and ends; +otherwise, it returns <b>nil</b>. +A third, optional numerical argument <code>init</code> specifies +where to start the search; +its default value is 1 and can be negative. +A value of <b>true</b> as a fourth, optional argument <code>plain</code> +turns off the pattern matching facilities, +so the function does a plain "find substring" operation, +with no characters in <code>pattern</code> being considered magic. +Note that if <code>plain</code> is given, then <code>init</code> must be given as well. + + +<p> +If the pattern has captures, +then in a successful match +the captured values are also returned, +after the two indices. + + + + +<p> +<hr><h3><a name="pdf-string.format"><code>string.format (formatstring, ···)</code></a></h3> + + +<p> +Returns a formatted version of its variable number of arguments +following the description given in its first argument (which must be a string). +The format string follows the same rules as the ISO C function <code>sprintf</code>. +The only differences are that the options/modifiers +<code>*</code>, <code>h</code>, <code>L</code>, <code>l</code>, <code>n</code>, +and <code>p</code> are not supported +and that there is an extra option, <code>q</code>. +The <code>q</code> option formats a string between double quotes, +using escape sequences when necessary to ensure that +it can safely be read back by the Lua interpreter. +For instance, the call + +<pre> + string.format('%q', 'a string with "quotes" and \n new line') +</pre><p> +may produce the string: + +<pre> + "a string with \"quotes\" and \ + new line" +</pre> + +<p> +Options +<code>A</code> and <code>a</code> (when available), +<code>E</code>, <code>e</code>, <code>f</code>, +<code>G</code>, and <code>g</code> all expect a number as argument. +Options <code>c</code>, <code>d</code>, +<code>i</code>, <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code> +expect an integer. +Option <code>q</code> expects a string; +option <code>s</code> expects a string without embedded zeros. +If the

also returns, as its second value, +the total number of matches that occurred. +The name <code>gsub</code> comes from <em>Global SUBstitution</em>. + + +<p> +If <code>repl</code> is a string, then its value is used for replacement. +The character <code>%</code> works as an escape character: +any sequence in <code>repl</code> of the form <code>%<em>d</em></code>, +with <em>d</em> between 1 and 9, +stands for the value of the <em>d</em>-th captured substring. +The sequence <code>%0</code> stands for the whole match. +The sequence <code>%%</code> stands for a single <code>%</code>. + + +<p> +If <code>repl</code> is a table, then the table is queried for every match, +using the first capture as the key. + + +<p> +If <code>repl</code> is a function, then this function is called every time a +match occurs, with all captured substrings passed as arguments, +in order. + + +<p> +In any case, +if the pattern specifies no captures, +then it behaves as if the whole pattern was inside a capture. + + +<p> +If the value returned by the table query or by the function call +is a string or a number, +then it is used as the replacement string; +otherwise, if it is <b>false</b> or <b>nil</b>, +then there is no replacement +(that is, the original match is kept in the string). + + +<p> +Here are some examples: + +<pre> + x = string.gsub("hello world", "(%w+)", "%1 %1") + --> x="hello hello world

+ + + + +<h3>6.4.1 – <a name="6.4.1">Patterns</a></h3> + +<p> +Patterns in Lua are described by regular strings, +which are interpreted as patterns by the pattern-matching functions +<a href="#pdf-string.find"><code>string.find</code></a>, +<a href="#pdf-string.gmatch"><code>string.gmatch</code></a>, +<a href="#pdf-string.gsub"><code>string.gsub</code></a>, +and <a href="#pdf-string.match"><code>string.match</code></a>. +This section describes the syntax and the meaning +(that is, what they match) of these strings. + + + +<h4>Character Class:</h4><p> +A <em>character class</em> is used to represent a set of characters. +The following combinations are allowed in describing a character class: + +<ul> + +<li><b><em>x</em>: </b> +(where <em>x</em> is not one of the <em>magic characters</em> +<code>^$()%.[]*+-?</code>) +represents the character <em>x</em> itself. +</li> + +<li><b><code>.</code>: </b> (a dot) represents all characters.</li> + +<li><b><code>%a</code>: </b> represents all letters.</li> + +<li><b><code>%c</code>: </b> represents all control characters.</li> + +<li><b><code>%d</code>: </b> represents all digits.</li> + +<li><b><code>%g</code>: </b> represents all printable characters except space.</li> + +<li><b><code>%l</code>: </b> represents all lowercase letters.</li> + +<li><b><code>%p</code>: </b> represents all punctuation characters.</li> + +<li><b><code>%s</code>: </b> represents all space characters.</li> + +<li><b><code>%u</code>: </b> represents all uppercase letters.</li> + +<li><b><code>%w</code>: </b> represents all alphanumeric characters.</li> + +<li><b><code>%x</code>: </b> represents all hexadecimal digits.</li> + +<li><b><code>%<em>x</em></code>: </b> (where <em>x</em> is any non-alphanumeric character) +represents the character <em>x</em>. +This is the standard way to escape the magic characters. +Any non-alphanumeric character +(including all punctuations, even the non-magical) +can be preceded by a '<code>%</code>' +when used to represent itself in a pattern. +</li> + +<li><b><code>[<em>set</em>]</code>: </b> +represents the class which is the union of all +characters in <em>set</em>. +A range of characters can be specified by +separating the end characters of the range, +in ascending order, with a '<code>-</code>'. +All classes <code>%</code><em>x</em> described above can also be used as +components in <em>set</em>. +All other characters in <em>set</em> represent themselves. +For example, <code>[%w_]</code> (or <code>[_%w]</code>) +represents all alphanumeric characters plus the underscore, +<code>[0-7]</code> represents the octal digits, +and <code>[0-7%l%-]</code> represents the octal digits plus +the lowercase letters plus the '<code>-</code>' character. + + +<p> +The interaction between ranges and classes is not defined. +Therefore, patterns like <code>[%a-z]</code> or <code>[a-%%]</code> +have no meaning. +</li> + +<li><b><code>[^<em>set</em>]</code>: </b> +represents the complement of <em>set</em>, +where <em>set</em> is interpreted as above. +</li> + +</ul><p> +For all classes represented by single letters (<code>%a</code>, <code>%c</code>, etc.), +the corresponding uppercase letter represents the complement of the class. +For instance, <code>%S</code> represents all non-space characters. + + +<p> +The definitions of letter, space, and other character groups +depend on the current locale. +In particular, the class <code>[a-z]</code> may not be equivalent to <code>%l</code>. + + + + + +<h4>Pattern Item:</h4><p> +A <em>pattern item</em> can be + +<ul> + +<li> +a single character class, +which matches any single character in the class; +</li> + +<li> +a single character class followed by '<code>*</code>', +which matches zero or more repetitions of characters in the class. +These repetition items will always match the longest possible sequence; +</li> + +<li> +a single character class followed by '<code>+</code>', +which matches one or more repetitions of characters in the class. +These repetition items will always match the longest possible sequence; +</li> + +<li> +a single character class followed by '<code>-</code>', +which also matches zero or more repetitions of characters in the class. +Unlike '<code>*</code>', +these repetition items will always match the shortest possible sequence; +</li> + +<li> +a single character class followed by '<code>?</code>', +which matches zero or one occurrence of a character in the class. +It always matches one occurrence if possible; +</li> + +<li> +<code>%<em>n</em></code>, for <em>n</em> between 1 and 9; +such item matches a substring equal to the <em>n</em>-th captured string +(see below); +</li> + +<li> +<code>%b<em>xy</em></code>, where <em>x</em> and <em>y</em> are two distinct characters; +such item matches strings that start with <em>x</em>, end with <em>y</em>, +and where the <em>x</em> and <em>y</em> are <em>balanced</em>. +This means that, if one reads the string from left to right, +counting <em>+1</em> for an <em>x</em> and <em>-1</em> for a <em>y</em>, +the ending <em>y</em> is the first <em>y</em> where the count reaches 0. +For instance, the item <code>%b()</code> matches expressions with +balanced parentheses. +</li> + +<li> +<code>%f[<em>set</em>]</code>, a <em>frontier pattern</em>; +such item matches an empty string at any position such that +the next character belongs to <em>set</em> +and the previous character does not belong to <em>set</em>. +The set <em>set</em> is interpreted as previously described. +The beginning and the end of the subject are handled as if +they were the character '<code>\0</code>'. +</li> + +</ul> + + + + +<h4>Pattern:</h4><p> +A <em>pattern</em> is a sequence of pattern items. +A caret '<code>^</code>' at the beginning of a pattern anchors the match at the +beginning of the subject string. +A '<code>$</code>' at the end of a pattern anchors the match at the +end of the subject string. +At other positions, +'<code>^</code>' and '<code>$</code>' have no special meaning and represent themselves. + + + + + +<h4>Captures:</h4><p> +A pattern can contain sub-patterns enclosed in parentheses; +they describe <em>captures</em>. +When a match succeeds, the substrings of the subject string +that match captures are stored (<em>captured</em>) for future use. +Captures are numbered according to their left parentheses. +For instance, in the pattern <code>"(a*(.)%w(%s*))"</code>, +the part of the string matching <code>"a*(.)%w(%s*)"</code> is +stored as the first capture (and therefore has number 1); +the character matching "<code>.</code>" is captured with number 2, +and the part matching "<code>%s*</code>" has number 3. + + +<p> +As a special case, the empty capture <code>()</code> captures +the current string position (a number). +For instance, if we apply the pattern <code>"()aa()"</code> on the +string <code>"flaaap"</code>, there will be two captures: 3 and 5. + + + + + + + +<h3>6.4.2 – <a name="6.4.2">Format Strings for Pack and Unpack</a></h3> + +<p> +The

</b> ignores environment variables;</li> +<li><b><code>--</code>: </b> stops handling options;</li> +<li><b><code>-</code>: </b> executes <code>stdin</code> as a file and stops handling options.</li> +</ul><p> +After handling its options, <code>lua</code> runs the given <em>script</em>. +When called without arguments, +<code>lua</code> behaves as <code>lua -v -i</code> +when the standard input (<code>stdin</code>) is a terminal, +and as <code>lua -</code> otherwise. + + +<p> +When called without option <code>-E</code>, +the interpreter checks for an environment variable <a name="pdf-LUA_INIT_5_3"><code>LUA_INIT_5_3</code></a> +(or <a name="pdf-LUA_INIT"><code>LUA_INIT</code></a> if the versioned name is not defined) +before running any argument. +If the variable content has the format <code>@<em>filename</em></code>, +then <code>lua</code> executes the file. +Otherwise, <code>lua</code> executes the string itself. + + +<p> +When called with option <code>-E</code>,

then print the value of <code>a</code>, +and finally run the file <code>script.lua</code> with no arguments. +(Here <code>$</code> is the shell prompt. Your prompt may be different.) + + +<p> +Before running any code, +<code>lua</code> collects all command-line arguments +in a global table called <code>arg</code>. +The script name goes to index 0, +the first argument after the script name goes to index 1, +and so on. +Any arguments before the script name +(that is, the interpreter name plus its options) +go to negative indices. +For instance, in the call + +<pre> + $ lua -la b.lua t1 t2 +</pre><p> +the table is like this: + +<pre> + arg = { [-2] = "lua", [-1] = "-la", + [0] = "b.lua", + [1] = "t1", [2] = "t2" } +</pre><p> +If there is no script in the call, +the interpreter name goes to index 0, +followed by the other arguments. +For instance, the call + +<pre> + $ lua -e "print(arg[1])" +</pre><p> +will print "<code>-e</code>". +If there is a script, +the script is called with parameters +<code>arg[1]</code>, ···, <code>arg[#arg]</code>. +(Like all chunks in Lua, +the script is compiled as a vararg function.) + + +<p> +In interactive mode, +Lua repeatedly prompts and waits for a line. +After reading a line, +Lua first try to interpret the line as an expression. +If it succeeds, it prints its value. +Otherwise, it interprets the line as a statement. +If you write an incomplete statement, +the interpreter waits for its completion +by issuing a different prompt. + + +<p> +In case of unprotected errors in the script, +the interpreter reports the error to the standard error stream. +If the error object is not a string but +has a metamethod <code>__tostring</code>, +the interpreter calls this metamethod to produce the final message. +Otherwise, the interpreter converts the error object to a string +and adds a stack traceback to it. + + +<p> +When finishing normally, +the interpreter closes its main Lua state +(see <a href="#lua_close"><code>lua_close</code></a>). +The script can avoid this step by +calling <a href="#pdf-os.exit"><code>os.exit</code></a> to terminate. + + +<p> +To allow the use of Lua as a +script interpreter in Unix systems, +the standalone interpreter skips +the first line of a chunk if it starts with <code>#</code>. +Therefore, Lua scripts can be made into executable programs +by using <code>chmod +x</code> and the <code>#!</code> form, +as in + +<pre> + #!/usr/local/bin/lua +</pre><p> +(Of course, +the location of the Lua interpreter may be different in your machine. +If <code>lua</code> is in your <code>PATH</code>, +then + +<pre> + #!/usr/bin/env lua +</pre><p> +is a more portable solution.) + + + +<h1>8 – <a name="8">Incompatibilities with the Previous Version</a></h1> + +<p> +Here we list the incompatibilities that you may find when moving a program +from Lua 5.2 to Lua 5.3. +You can avoid some incompatibilities by compiling Lua with +appropriate options (see file <code>luaconf.h</code>). +However, +all these compatibility options will be removed in the future. + + +<p> +Lua versions can always change the C API in ways that +do not imply source-code changes in a program, +such as the numeric values for constants +or the implementation of functions as macros. +Therefore, +you should not assume that binaries are compatible between +different Lua versions. +Always recompile clients of the Lua API when +using a new version. + + +<p> +Similarly, Lua versions can always change the internal representation +of precompiled chunks;
