Changes to Readline + +a. Fixes to avoid core dumps because of null pointer references in the + multibyte character code. + +b. Fix to avoid infinite recursion caused by certain key combinations. + +c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly. + +d. Readline no longer tries to read ahead more than one line of input, even + when more is available. + +e. Fixed the code that adjusts the point to not mishandle null wide + characters. + +f. Fixed a bug in the history expansion `g' modifier that caused it to skip + every other match. + +g. Fixed a bug that caused the prompt to overwrite previous output when the + output doesn't contain a newline and the locale supports multibyte + characters. This same change fixes the problem of readline redisplay + slowing down dramatically as the line gets longer in multibyte locales. + +h. History traversal with arrow keys in vi insertion mode causes the cursor + to be placed at the end of the new line, like in emacs mode. + +i. The locale initialization code does a better job of using the right + precedence and defaulting when checking the appropriate environment + variables. + +j. Fixed the history word tokenizer to handle <( and >( better when used as + part of bash. + +k. The overwrite mode code received several bug fixes to improve undo. + +l. Many speedups to the multibyte character redisplay code. + +m. The callback character reading interface should not hang waiting to read + keyboard input. + +n. Fixed a bug with redoing vi-mode `s' command. + +o. The code that initializes the terminal tracks changes made to the terminal + special characters with stty(1) (or equivalent), so that these changes + are reflected in the readline bindings. New application-callable function + to make it work: rl_tty_unset_default_bindings(). + +p. Fixed a bug that could cause garbage to be inserted in the buffer when + changing character case in vi mode when using a multibyte locale. + +q. Fixed a bug in the redisplay code that caused problems on systems + supporting multibyte characters when moving between history lines when the + new line has more glyphs but fewer bytes. + +r. Undo and redo now work better after exiting vi insertion mode. + +s. Make sure system calls are restarted after a SIGWINCH is received using + SA_RESTART. + +t. Improvements to the code that displays possible completions when using + multibyte characters. + +u. Fixed a problem when parsing nested if statements in inputrc files. + +v. The completer now takes multibyte characters into account when looking for + quoted substrings on which to perform completion. + +w. The history search functions now perform better bounds checking on the + history list. + +x. Change to history expansion functions to treat `^' as equivalent to word + one, as the documention states. + +y. Some changes to the display code to improve display and redisplay of + multibyte characters. + +z. Changes to speed up the multibyte character redisplay code. + +aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the + last character of a word if invoked while point was on the word's + next-to-last character. + +bb. Fixed a bug that could cause incorrect filename quoting when + case-insensitive completion was enabled and the word being completed + contained backslashes quoting word break characters. + +cc. Fixed a bug in redisplay triggered when the prompt string contains + invisible characters. + +dd. Fixed some display (and other) bugs encountered in multibyte locales + when a non-ascii character was the last character on a line. + +ee. Fixed some display bugs caused by multibyte characters in prompt strings. + +ff. Fixed a problem with history expansion caused by non-whitespace characters + used as history word delimiters. + +gg. Fixed a problem that could cause readline to refer to freed memory when + moving between history lines while doing searches. + +hh. Improvements to the code that expands and displays prompt strings + containing multibyte characters. + +ii. Fixed a problem with vi-mode not correctly remembering the numeric argument + to the last `c'hange command for later use with `.'. + +jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work + incorrectly. + +kk. Fixed a problem in vi-mode that caused the last text modification command + to not be remembered across different command lines. + +ll. Fixed problems with changing characters and changing case at the end of + the line. + +mm. Fixed a problem with readline saving the contents of the current line + before beginning a non-interactive search. + +nn. Fixed a problem with EOF detection when using rl_event_hook. + +oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric + arguments. + +2. New Features in Readline + +a. History expansion has a new `a' modifier equivalent to the `g' modifier + for compatibility with the BSD csh. + +b. History expansion has a new `G' modifier equivalent to the BSD csh `g' + modifier, which performs a substitution once per word. + +c. All non-incremental search operations may now undo the operation of + replacing the current line with the history line. + +d. The text inserted by an `a' command in vi mode can be reinserted with + `.'. + +e. New bindable variable, `show-all-if-unmodified'. If set, the readline + completer will list possible completions immediately if there is more + than one completion and partial completion cannot be performed. + +f. There is a new application-callable `free_history_entry()' function. + +g. History list entries now contain timestamp information; the history file + functions know how to read and write timestamp information associated + with each entry. + +h. Four new key binding functions have been added: + + rl_bind_key_if_unbound() + rl_bind_key_if_unbound_in_map() + rl_bind_keyseq_if_unbound() + rl_bind_keyseq_if_unbound_in_map() + +i. New application variable, rl_completion_quote_character, set to any + quote character readline finds before it calls the application completion + function. + +j. New application variable, rl_completion_suppress_quote, settable by an + application completion function. If set to non-zero, readline does not + attempt to append a closing quote to a completed word. + +k. New application variable, rl_completion_found_quote, set to a non-zero + value if readline determines that the word to be completed is quoted. + Set before readline calls any application completion function. + +l. New function hook, rl_completion_word_break_hook, called when readline + needs to break a line into words when completion is attempted. Allows + the word break characters to vary based on position in the line. + +m. New bindable command: unix-filename-rubout. Does the same thing as + unix-word-rubout, but adds `/' to the set of word delimiters. + +n. When listing completions, directories have a `/' appended if the + `mark-directories' option has been enabled. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.3, +and the previous version, readline-4.2a. + +1. Changes to Readline + +a. Fixed output of comment-begin character when listing variable values. + +b. Added some default key bindings for common escape sequences produced by + HOME and END keys. + +c. Fixed the mark handling code to be more emacs-compatible. + +d. A bug was fixed in the code that prints possible completions to keep it + from printing empty strings in certain circumstances. + +e. Change the key sequence printing code to print ESC as M\- if ESC is a + meta-prefix character -- it's easier for users to understand than \e. + +f. Fixed unstifle_history() to return values that match the documentation. + +g. Fixed the event loop (rl_event_hook) to handle the case where the input + file descriptor is invalidated. + +h. Fixed the prompt display code to work better when the application has a + custom redisplay function. + +i. Changes to make reading and writing the history file a little faster, and + to cope with huge history files without calling abort(3) from xmalloc. + +j. The vi-mode `S' and `s' commands are now undone correctly. + +k. Fixed a problem which caused the display to be messed up when the last + line of a multi-line prompt (possibly containing invisible characters) + was longer than the screen width. + +2. New Features in Readline + +a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both + be bound to readline functions. Now the arrow keys may be used in vi + insert mode. + +b. When listing completions, and the number of lines displayed is more than + the screen length, readline uses an internal pager to display the results. + This is controlled by the `page-completions' variable (default on). + +c. New code to handle editing and displaying multibyte characters. + +d. The behavior introduced in bash-2.05a of deciding whether or not to + append a slash to a completed name that is a symlink to a directory has + been made optional, controlled by the `mark-symlinked-directories' + variable (default is the 2.05a behavior). + +e. The `insert-comment' command now acts as a toggle if given a numeric + argument: if the first characters on the line don't specify a + comment, insert one; if they do, delete the comment text + +f. New application-settable completion variable: + rl_completion_mark_symlink_dirs, allows an application's completion + function to temporarily override the user's preference for appending + slashes to names which are symlinks to directories. + +g. New function available to application completion functions: + rl_completion_mode, to tell how the completion function was invoked + and decide which argument to supply to rl_complete_internal (to list + completions, etc.). + +h. Readline now has an overwrite mode, toggled by the `overwrite-mode' + bindable command, which could be bound to `Insert'. + +i. New application-settable completion variable: + rl_completion_suppress_append, inhibits appending of + rl_completion_append_character to completed words. + +j. New key bindings when reading an incremental search string: ^W yanks + the currently-matched word out of the current line into the search + string; ^Y yanks the rest of the current line into the search string, + DEL or ^H deletes characters from the search string. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.2a, +and the previous version, readline-4.2. + +1. Changes to Readline + +a. More `const' and type casting fixes. + +b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer + overflow problems. + +c. The completion code no longer appends a `/' or ` ' to a match when + completing a symbolic link that resolves to a directory name, unless + the match does not add anything to the word being completed. This + means that a tab will complete the word up to the full name, but not + add anything, and a subsequent tab will add a slash. + +d. Fixed a trivial typo that made the vi-mode `dT' command not work. + +e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert. + +f. Fixed the tty code so that ^V works more than once. + +g. Changed the use of __P((...)) for function prototypes to PARAMS((...)) + because the use of __P in typedefs conflicted g++ and glibc. + +h. The completion code now attempts to do a better job of preserving the + case of the word the user typed if ignoring case in completions. + +i. Readline defaults to not echoing the input and lets the terminal + initialization code enable echoing if there is a controlling terminal. + +j. The key binding code now processes only two hex digits after a `\x' + escape sequence, and the documentation was changed to note that the + octal and hex escape sequences result in an eight-bit value rather + than strict ASCII. + +k. Fixed a few places where negative array subscripts could have occurred. + +l. Fixed the vi-mode code to use a better method to determine the bounds of + the array used to hold the marks, and to avoid out-of-bounds references. + +m. Fixed the defines in chardefs.h to work better when chars are signed. + +n. Fixed configure.in to use the new names for bash autoconf macros. + +o. Readline no longer attempts to define its own versions of some ctype + macros if they are implemented as functions in libc but not as macros in + <ctype.h>. + +p. Fixed a problem where rl_backward could possibly set point to before + the beginning of the line. + +q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause + include file problems. + +2. New Features in Readline + +a. Added extern declaration for rl_get_termcap to readline.h, making it a + public function (it was always there, just not in readline.h). + +b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402, + RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2. + +c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION. + +d. New bindable boolean readline variable: match-hidden-files. Controls + completion of files beginning with a `.' (on Unix). Enabled by default. + +e. The history expansion code now allows any character to terminate a + `:first-' modifier, like csh. + +f. The incremental search code remembers the last search string and uses + it if ^R^R is typed without a search string. + +h. New bindable variable `history-preserve-point'. If set, the history + code attempts to place the user at the same location on each history + line retrived with previous-history or next-history. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.2, +and the previous version, readline-4.1. + +1. Changes to Readline + +a. When setting the terminal attributes on systems using `struct termio', + readline waits for output to drain before changing the attributes. + +b. A fix was made to the history word tokenization code to avoid attempts to + dereference a null pointer. + +c. Readline now defaults rl_terminal_name to $TERM if the calling application + has left it unset, and tries to initialize with the resultant value. + +d. Instead of calling (*rl_getc_function)() directly to get input in certain + places, readline now calls rl_read_key() consistently. + +e. Fixed a bug in the completion code that allowed a backslash to quote a + single quote inside a single-quoted string. + +f. rl_prompt is no longer assigned directly from the argument to readline(), + but uses memory allocated by readline. This allows constant strings to + be passed to readline without problems arising when the prompt processing + code wants to modify the string. + +g. Fixed a bug that caused non-interactive history searches to return the + wrong line when performing multiple searches backward for the same string. + +h. Many variables, function arguments, and function return values are now + declared `const' where appropriate, to improve behavior when linking with + C++ code. + +i. The control character detection code now works better on systems where + `char' is unsigned by default. + +j. The vi-mode numeric argument is now capped at 999999, just like emacs mode. + +k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been + replaced with a set of specific prototyped typedefs, though they are + still in the readline header files for backwards compatibility. + +m. Nearly all of the (undocumented) internal global variables in the library + now have an _rl_ prefix -- there were a number that did not, like + screenheight, screenwidth, alphabetic, etc. + +n. The ding() convenience function has been renamed to rl_ding(), though the + old function is still defined for backwards compatibility. + +o. The completion convenience functions filename_completion_function, + username_completion_function, and completion_matches now have an rl_ + prefix, though the old names are still defined for backwards compatibility. + +p. The functions shared by readline and bash (linkage is satisfied from bash + when compiling with bash, and internally otherwise) now have an sh_ prefix. + +q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so + that the `soname' contains only the major version number rather than the + major and minor numbers. + +r. Fixed a redisplay bug that occurred when the prompt spanned more than one + physical line and contained invisible characters. + +s. Added a missing `includedir' variable to the Makefile. + +t. When installing the shared libraries, make sure symbolic links are relative. + +u. Added configure test so that it can set `${MAKE}' appropriately. + +v. Fixed a bug in rl_forward that could cause the point to be set to before + the beginning of the line in vi mode. + +w. Fixed a bug in the callback read-char interface to make it work when a + readline function pushes some input onto the input stream with + rl_execute_next (like the incremental search functions). + +x. Fixed a file descriptor leak in the history file manipulation code that + was tripped when attempting to truncate a non-regular file (like + /dev/null). + +y. Changes to make all of the exported readline functions declared in + readline.h have an rl_ prefix (rltty_set_default_bindings is now + rl_tty_set_default_bindings, crlf is now rl_crlf, etc.) + +z. The formatted documentation included in the base readline distribution + is no longer removed on a `make distclean'. + +aa. Some changes were made to avoid gcc warnings with -Wall. + +bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so + `set keymap EMACS' works. + +cc. The history file writing and truncation functions now return a useful + status on error. + +dd. Fixed a bug that could cause applications to dereference a NULL pointer + if a NULL second argument was passed to history_expand(). + +ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero + value, rl_read_key() now immediately returns '\n' (which is assumed to + be bound to accept-line). + +2. New Features in Readline + +a. The blink timeout for paren matching is now settable by applications, + via the rl_set_paren_blink_timeout() function. + +b. _rl_executing_macro has been renamed to rl_executing_macro, which means + it's now part of the public interface. + +c. Readline has a new variable, rl_readline_state, which is a bitmap that + encapsulates the current state of the library; intended for use by + callbacks and hook functions. + +d. rlfe has a new -l option to log input and output (-a appends to logfile), + a new -n option to set the readline application name, and -v and -h + options for version and help information. + +e. rlfe can now perform filename completion for the inferior process if the + OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the + inferior's current working directory. + +f. A new file, rltypedefs.h, contains the new typedefs for function pointers + and is installed by `make install'. + +g. New application-callable function rl_set_prompt(const char *prompt): + expands its prompt string argument and sets rl_prompt to the result. + +h. New application-callable function rl_set_screen_size(int rows, int cols): + public method for applications to set readline's idea of the screen + dimensions. + +i. The history example program (examples/histexamp.c) is now built as one + of the examples. + +j. The documentation has been updated to cover nearly all of the public + functions and variables declared in readline.h. + +k. New function, rl_get_screen_size (int *rows, int *columns), returns + readline's idea of the screen dimensions. + +l. The timeout in rl_gather_tyi (readline keyboard input polling function) + is now settable via a function (rl_set_keyboard_input_timeout()). + +m. Renamed the max_input_history variable to history_max_entries; the old + variable is maintained for backwards compatibility. + +n. The list of characters that separate words for the history tokenizer is + now settable with a variable: history_word_delimiters. The default + value is as before. + +o. There is a new history.3 manual page documenting the history library. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.1, +and the previous version, readline-4.0. + +1. Changes to Readline + +a. Changed the HTML documents so that the table-of-contents is no longer + a separate file. + +b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x, + OSF/1. + +c. The shared library major and minor versions are now constructed + automatically by configure and substituted into the makefiles. + +d. It's now possible to install the shared libraries separately from the + static libraries. + +e. The history library tries to truncate the history file only if it is a + regular file. + +f. A bug that caused _rl_dispatch to address negative array indices on + systems with signed chars was fixed. + +g. rl-yank-nth-arg now leaves the history position the same as when it was + called. + +h. Changes to the completion code to handle MS-DOS drive-letter:pathname + filenames. + +i. Completion is now case-insensitive by default on MS-DOS. + +j. Fixes to the history file manipulation code for MS-DOS. + +k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS. + +l. Some fixes were made to the redisplay code for better operation on MS-DOS. + +m. The quoted-insert code will now insert tty special chars like ^C. + +n. A bug was fixed that caused the display code to reference memory before + the start of the prompt string. + +o. More support for __EMX__ (OS/2). + +p. A bug was fixed in readline's signal handling that could cause infinite + recursion in signal handlers. + +q. A bug was fixed that caused the point to be less than zero when rl_forward + was given a very large numeric argument. + +r. The vi-mode code now gets characters via the application-settable value + of rl_getc_function rather than calling rl_getc directly. + +s. The history file code now uses O_BINARY mode when reading and writing + the history file on cygwin32. + +t. Fixed a bug in the redisplay code for lines with more than 256 line + breaks. + +u. A bug was fixed which caused invisible character markers to not be + stripped from the prompt string if the terminal was in no-echo mode. + +v. Readline no longer tries to get the variables it needs for redisplay + from the termcap entry if the calling application has specified its + own redisplay function. Readline treats the terminal as `dumb' in + this case. + +w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape + sequences is redrawn correctly. + +x. Changes to the install and install-shared targets so that the libraries + and header files are installed separately. + +2. New Features in Readline + +a. A new Readline `user manual' is in doc/rluserman.texinfo. + +b. Parentheses matching is now always compiled into readline, and enabled + or disabled when the value of the `blink-matching-paren' variable is + changed. + +c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename. + +d. MS-DOS systems now use ~/_history as the default history file. + +e. history-search-{forward,backward} now leave the point at the end of the + line when the string to search for is empty, like + {reverse,forward}-search-history. + +f. history-search-{forward,backward} now leave the last history line found + in the readline buffer if the second or subsequent search fails. + +g. New function for use by applications: rl_on_new_line_with_prompt, used + when an application displays the prompt itself before calling readline(). + +h. New variable for use by applications: rl_already_prompted. An application + that displays the prompt itself before calling readline() must set this to + a non-zero value. + +i. A new variable, rl_gnu_readline_p, always 1. The intent is that an + application can verify whether or not it is linked with the `real' + readline library or some substitute. + +j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program + is included in the examples subdirectory, though it is not built + by default. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.0, +and the previous version, readline-2.2. + +1. Changes to Readline + +a. The version number is now 4.0, to match the major and minor version + numbers on the shared readline and history libraries. Future + releases will maintain the identical numbering. + +b. Fixed a typo in the `make install' recipe that copied libreadline.a + to libhistory.old right after installing it. + +c. The readline and history info files are now installed out of the source + directory if they are not found in the build directory. + +d. The library no longer exports a function named `savestring' -- backwards + compatibility be damned. + +e. There is no longer any #ifdef SHELL code in the source files. + +f. Some changes were made to the key binding code to fix memory leaks and + better support Win32 systems. + +g. Fixed a silly typo in the paren matching code -- it's microseconds, not + milliseconds. + +h. The readline library should be compilable by C++ compilers. + +i. The readline.h public header file now includes function prototypes for + all readline functions, and some changes were made to fix errors in the + source files uncovered by the use of prototypes. + +j. The maximum numeric argument is now clamped at 1000000. + +k. Fixes to rl_yank_last_arg to make it behave better. + +l. Fixed a bug in the display code that caused core dumps if the prompt + string length exceeded 1024 characters. + +m. The menu completion code was fixed to properly insert a single completion + if there is only one match. + +n. A bug was fixed that caused the display code to improperly display tabs + after newlines. + +o. A fix was made to the completion code in which a typo caused the wrong + value to be passed to the function that computed the longest common + prefix of the list of matches. + +p. The completion code now checks the value of rl_filename_completion_desired, + which is set by application-supplied completion functions to indicate + that filename completion is being performed, to decide whether or not to + call an application-supplied `ignore completions' function. + +q. Code was added to the history library to catch history substitutions + using `&' without a previous history substitution or search having been + performed. + + +2. New Features in Readline + +a. There is a new script, support/shobj-conf, to do system-specific shared + object and library configuration. It generates variables for configure + to substitute into makefiles. The README file provides a detailed + explanation of the shared library creation process. + +b. Shared libraries and objects are now built in the `shlib' subdirectory. + There is a shlib/Makefile.in to control the build process. `make shared' + from the top-level directory is still the right way to build shared + versions of the libraries. + +c. rlconf.h is now installed, so applications can find out which features + have been compiled into the installed readline and history libraries. + +d. rlstdc.h is now an installed header file. + +e. Many changes to the signal handling: + o Readline now catches SIGQUIT and cleans up the tty before returning; + o A new variable, rl_catch_signals, is available to application writers + to indicate to readline whether or not it should install its own + signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP, + SIGTTIN, and SIGTTOU; + o A new variable, rl_catch_sigwinch, is available to application + writers to indicate to readline whether or not it should install its + own signal handler for SIGWINCH, which will chain to the calling + applications's SIGWINCH handler, if one is installed; + o There is a new function, rl_free_line_state, for application signal + handlers to call to free up the state associated with the current + line after receiving a signal; + o There is a new function, rl_cleanup_after_signal, to clean up the + display and terminal state after receiving a signal; + o There is a new function, rl_reset_after_signal, to reinitialize the + terminal and display state after an application signal handler + returns and readline continues + +f. There is a new function, rl_resize_terminal, to reset readline's idea of + the screen size after a SIGWINCH. + +g. New public functions: rl_save_prompt and rl_restore_prompt. These were + previously private functions with a `_' prefix. These functions are + used when an application wants to write a message to the `message area' + with rl_message and have the prompt restored correctly when the message + is erased. + +h. New function hook: rl_pre_input_hook, called just before readline starts + reading input, after initialization. + +i. New function hook: rl_display_matches_hook, called when readline would + display the list of completion matches. The new function + rl_display_match_list is what readline uses internally, and is available + for use by application functions called via this hook. + +j. New bindable function, delete-char-or-list, like tcsh. + +k. A new variable, rl_erase_empty_line, which, if set by an application using + readline, will cause readline to erase, prompt and all, lines on which the + only thing typed was a newline. + +l. There is a new script, support/shlib-install, to install and uninstall + the shared readline and history libraries. + +m. A new bindable variable, `isearch-terminators', which is a string + containing the set of characters that should terminate an incremental + search without being executed as a command. + +n. A new bindable function, forward-backward-delete-char. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-2.2, +and the previous version, readline-2.1. + +1. Changes to Readline + +a. Added a missing `extern' to a declaration in readline.h that kept + readline from compiling cleanly on some systems. + +b. The history file is now opened with mode 0600 when it is written for + better security. + +c. Changes were made to the SIGWINCH handling code so that prompt redisplay + is done better. + +d. ^G now interrupts incremental searches correctly. + +e. A bug that caused a core dump when the set of characters to be quoted + when completing words was empty was fixed. + +f. Fixed a problem in the readline test program rltest.c that caused a core + dump. + +g. The code that handles parser directives in inputrc files now displays + more error messages. + +h. The history expansion code was fixed so that the appearance of the + history comment character at the beginning of a word inhibits history + expansion for that word and the rest of the input line. + +i. The code that prints completion listings now behaves better if one or + more of the filenames contains non-printable characters. + +j. The time delay when showing matching parentheses is now 0.5 seconds. + + +2. New Features in Readline + +a. There is now an option for `iterative' yank-last-arg handline, so a user + can keep entering `M-.', yanking the last argument of successive history + lines. + +b. New variable, `print-completions-horizontally', which causes completion + matches to be displayed across the screen (like `ls -x') rather than up + and down the screen (like `ls'). + +c. New variable, `completion-ignore-case', which causes filename completion + and matching to be performed case-insensitively. + +d. There is a new bindable command, `magic-space', which causes history + expansion to be performed on the current readline buffer and a space to + be inserted into the result. + +e. There is a new bindable command, `menu-complete', which enables tcsh-like + menu completion (successive executions of menu-complete insert a single + completion match, cycling through the list of possible completions). + +f. There is a new bindable command, `paste-from-clipboard', for use on Win32 + systems, to insert the text from the Win32 clipboard into the editing + buffer. + +g. The key sequence translation code now understands printf-style backslash + escape sequences, including \NNN octal escapes. These escape sequences + may be used in key sequence definitions or macro values. + +h. An `$include' inputrc file parser directive has been added. diff --git a/vendor/readline/COPYING b/vendor/readline/COPYING new file mode 100644 index 00000000..1bf15263 --- /dev/null +++ b/vendor/readline/COPYING @@ -0,0 +1,339 @@ + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 Free Software Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it.

The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2.

(This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11.

If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes some time. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile readline and build the static readline + and history libraries. If supported, the shared readline and history + libraries will be built also. See below for instructions on compiling + the other parts of the distribution. Typing `make everything' will + cause the static and shared libraries (if supported) and the example + programs to be built. + + 3. Type `make install' to install the static readline and history + libraries, the readline include files, the documentation, and, if + supported, the shared readline and history libraries. + + 4. You can remove the created libraries and object files from the + build directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile readline for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the readline developers, and should be used with care. + +The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It +uses those values to create a `Makefile' in the build directory, +and Makefiles in the `doc', `shlib', and `examples' +subdirectories. It also creates a `config.h' file containing +system-dependent definitions. Finally, it creates a shell script +`config.status' that you can run in the future to recreate the +current configuration, a file `config.cache' that saves the +results of its tests to speed up reconfiguring, and a file +`config.log' containing compiler output (useful mainly for +debugging `configure'). + +If you need to do unusual things to compile readline, please try +to figure out how `configure' could check whether to do them, and +mail diffs or instructions to <bug-readline@gnu.org> so they can +be considered for the next release. If at some point +`config.cache' contains results you don't want to keep, you may +remove or edit it. + +The file `configure.in' is used to create `configure' by a +program called `autoconf'. You only need `configure.in' if you +want to change it or regenerate `configure' using a newer version +of `autoconf'. The readline `configure.in' requires autoconf +version 2.50 or newer. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + +You can compile readline for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + +If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile readline for one architecture at a +time in the source code directory. After you have installed +readline for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' will install the readline libraries in +`/usr/local/lib', the include files in +`/usr/local/include/readline', the man pages in `/usr/local/man', +and the info files in `/usr/local/info'. You can specify an +installation prefix other than `/usr/local' by giving `configure' +the option `--prefix=PATH' or by supplying a value for the +DESTDIR variable when running `make install'. + +You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. +If you give `configure' the option `--exec-prefix=PATH', the +readline Makefiles will use PATH as the prefix for installing the +libraries. Documentation and other data files will still use the +regular prefix. + +Specifying the System Type +========================== + +There may be some features `configure' can not figure out +automatically, but need to determine by the type of host readline +will run on. Usually `configure' can figure that out, but if it +prints a message saying it can not guess the host type, give it +the `--host=TYPE' option. TYPE can either be a short name for +the system type, such as `sun4', or a canonical name with three +fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). + +See the file `config.sub' for the possible values of each field. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: the readline `configure' looks for a site script, but not +all `configure' scripts do. + +Operation Controls +================== + +`configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. + +Optional Features +================= + +The readline `configure' recognizes a single `--with-PACKAGE' option: + +`--with-curses' + This tells readline that it can find the termcap library functions + (tgetent, et al.) in the curses library, rather than a separate + termcap library. Readline uses the termcap functions, but does not + link with the termcap or curses library itself, allowing applications + which link with readline the to choose an appropriate library. + This option tells readline to link the example programs with the + curses library rather than libtermcap. + +`configure' also recognizes two `--enable-FEATURE' options: + +`--enable-shared' + Build the shared libraries by default on supported platforms. The + default is `yes'. + +`--enable-static' + Build the static libraries by default. The default is `yes'. + +Shared Libraries +================ + +There is support for building shared versions of the readline and +history libraries. The configure script creates a Makefile in +the `shlib' subdirectory, and typing `make shared' will cause +shared versions of the readline and history libraries to be built +on supported platforms. + +If `configure' is given the `--enable-shared' option, it will attempt +to build the shared libraries by default on supported platforms. + +Configure calls the script support/shobj-conf to test whether or +not shared library creation is supported and to generate the values +of variables that are substituted into shlib/Makefile. If you +try to build shared libraries on an unsupported platform, `make' +will display a message asking you to update support/shobj-conf for +your platform. + +If you need to update support/shobj-conf, you will need to create +a `stanza' for your operating system and compiler. The script uses +the value of host_os and ${CC} as determined by configure. For +instance, FreeBSD 4.2 with any version of gcc is identified as +`freebsd4.2-gcc*'. + +In the stanza for your operating system-compiler pair, you will need to +define several variables. They are: + +SHOBJ_CC The C compiler used to compile source files into shareable + object files. This is normally set to the value of ${CC} + by configure, and should not need to be changed. + +SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create + position-independent code. If you are using gcc, this + should probably be set to `-fpic'. + +SHOBJ_LD The link editor to be used to create the shared library from + the object files created by $SHOBJ_CC. If you are using + gcc, a value of `gcc' will probably work. + +SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation. + If you are using gcc, `-shared' may be all that is necessary. + These should be the flags needed for generic shared object + creation. + +SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library + creation. Many systems use the -R option to the link + editor to embed a path within the library for run-time + library searches. A reasonable value for such systems would + be `-R$(libdir)'. + +SHLIB_LIBS Any additional libraries that shared libraries should be + linked against when they are created. + +SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when + generating the filename of the shared library. Many systems + use `so'; HP-UX uses `sl'. + +SHLIB_LIBVERSION The string to append to the filename to indicate the version + of the shared library. It should begin with $(SHLIB_LIBSUFF), + and possibly include version information that allows the + run-time loader to load the version of the shared library + appropriate for a particular program. Systems using shared + libraries similar to SunOS 4.x use major and minor library + version numbers; for those systems a value of + `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate. + Systems based on System V Release 4 don't use minor version + numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems. + Other Unix versions use different schemes. + +SHLIB_STATUS Set this to `supported' when you have defined the other + necessary variables. Make uses this to determine whether + or not shared library creation should be attempted. If + shared libraries are not supported, this will be set to + `unsupported'. + +You should look at the existing stanzas in support/shobj-conf for ideas. + +Once you have updated support/shobj-conf, re-run configure and type +`make shared' or `make'. The shared libraries will be created in the +shlib subdirectory. + +If shared libraries are created, `make install' will install them. +You may install only the shared libraries by running `make +install-shared' from the top-level build directory. Running `make +install' in the shlib subdirectory will also work. If you don't want +to install any created shared libraries, run `make install-static'. diff --git a/vendor/readline/MANIFEST b/vendor/readline/MANIFEST new file mode 100644 index 00000000..5b023405 --- /dev/null +++ b/vendor/readline/MANIFEST @@ -0,0 +1,134 @@ +# +# Master distribution manifest for the standalone readline distribution +# +doc d +examples d +support d +shlib d +COPYING f +README f +MANIFEST f +INSTALL f +CHANGELOG f +CHANGES f +NEWS f +USAGE f +aclocal.m4 f +config.h.in f +configure f +configure.in f +Makefile.in f +ansi_stdlib.h f +chardefs.h f +history.h f +histlib.h f +keymaps.h f +posixdir.h f +posixjmp.h f +posixstat.h f +readline.h f +rlconf.h f +rldefs.h f +rlmbutil.h f +rlprivate.h f +rlshell.h f +rlstdc.h f +rltty.h f +rltypedefs.h f +rlwinsize.h f +tcap.h f +tilde.h f +xmalloc.h f +bind.c f +callback.c f +compat.c f +complete.c f +display.c f +emacs_keymap.c f +funmap.c f +input.c f +isearch.c f +keymaps.c f +kill.c f +macro.c f +mbutil.c f +misc.c f +nls.c f +parens.c f +readline.c f +rltty.c f +savestring.c f +search.c f +shell.c f +signals.c f +terminal.c f +text.c f +tilde.c f +undo.c f +util.c f +vi_keymap.c f +vi_mode.c f +xmalloc.c f +history.c f +histexpand.c f +histfile.c f +histsearch.c f +shlib/Makefile.in f +support/config.guess f +support/config.rpath f +support/config.sub f +support/install.sh f +support/mkdirs f +support/mkdist f +support/mkinstalldirs f +support/shobj-conf f +support/shlib-install f +support/wcwidth.c f +doc/Makefile.in f +doc/texinfo.tex f +doc/version.texi f +doc/fdl.texi f +doc/rlman.texi f +doc/rltech.texi f +doc/rluser.texi f +doc/rluserman.texi f +doc/history.texi f +doc/hstech.texi f +doc/hsuser.texi f +doc/readline.3 f +doc/history.3 f +doc/texi2dvi f +doc/texi2html f +examples/Makefile.in f +examples/excallback.c f +examples/fileman.c f +examples/manexamp.c f +examples/readlinebuf.h f +examples/rl-fgets.c f +examples/rlcat.c f +examples/rlfe.c f +examples/rltest.c f +examples/rl.c f +examples/rlversion.c f +examples/histexamp.c f +examples/Inputrc f +# formatted documentation, from MANIFEST.doc +doc/readline.ps f +doc/history.ps f +doc/rluserman.ps f +doc/readline.dvi f +doc/history.dvi f +doc/rluserman.dvi f +doc/readline.info f +doc/history.info f +doc/rluserman.info f +doc/readline.html f +doc/history.html f +doc/rluserman.html f +doc/readline.0 f +doc/history.0 f +doc/readline_3.ps f +doc/history_3.ps f +doc/history.pdf f +doc/readline.pdf f +doc/rluserman.pdf f diff --git a/vendor/readline/Makefile b/vendor/readline/Makefile new file mode 100644 index 00000000..cd35509d --- /dev/null +++ b/vendor/readline/Makefile @@ -0,0 +1,559 @@ +## -*- text -*- ## +# Master Makefile for the GNU readline library. +# Copyright (C) 1994-2004 Free Software Foundation, Inc. + +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Both +Emacs and vi editing modes are available. The Readline library includes +additional functions to maintain a list of previously-entered command +lines, to recall and perhaps reedit those lines, and perform csh-like +history expansion on previous commands. + +The history facilites are also placed into a separate library, the +History library, as part of the build process. The History library +may be used without Readline in applications which desire its +capabilities. + +The Readline library is free software, distributed under the terms of +the [GNU] General Public License, version 2. For more information, see +the file COPYING. + +To build the library, try typing `./configure', then `make'. The +configuration process is automated, so no further intervention should +be necessary. Readline builds with `gcc' by default if it is +available. If you want to use `cc' instead, type + + CC=cc ./configure + +if you are using a Bourne-style shell. If you are not, the following +may work: + + env CC=cc ./configure + +Read the file INSTALL in this directory for more information about how +to customize and control the build process. + +The file rlconf.h contains C preprocessor defines that enable and disable +certain Readline features. + +The special make target `everything' will build the static and shared +libraries (if the target platform supports them) and the examples. + +Examples +======== + +There are several example programs that use Readline features in the +examples directory. The `rl' program is of particular interest. It +is a command-line interface to Readline, suitable for use in shell +scripts in place of `read'. + +Shared Libraries +================ + +There is skeletal support for building shared versions of the +Readline and History libraries. The configure script creates +a Makefile in the `shlib' subdirectory, and typing `make shared' +will cause shared versions of the Readline and History libraries +to be built on supported platforms. + +If `configure' is given the `--enable-shared' option, it will attempt +to build the shared libraries by default on supported platforms. + +Configure calls the script support/shobj-conf to test whether or +not shared library creation is supported and to generate the values +of variables that are substituted into shlib/Makefile. If you +try to build shared libraries on an unsupported platform, `make' +will display a message asking you to update support/shobj-conf for +your platform. + +If you need to update support/shobj-conf, you will need to create +a `stanza' for your operating system and compiler. The script uses +the value of host_os and ${CC} as determined by configure. For +instance, FreeBSD 4.2 with any version of gcc is identified as +`freebsd4.2-gcc*'. + +In the stanza for your operating system-compiler pair, you will need to +define several variables. They are: + +SHOBJ_CC The C compiler used to compile source files into shareable + object files. This is normally set to the value of ${CC} + by configure, and should not need to be changed. + +SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create + position-independent code. If you are using gcc, this + should probably be set to `-fpic'. + +SHOBJ_LD The link editor to be used to create the shared library from + the object files created by $SHOBJ_CC. If you are using + gcc, a value of `gcc' will probably work. + +SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation. + If you are using gcc, `-shared' may be all that is necessary. + These should be the flags needed for generic shared object + creation. + +SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library + creation. Many systems use the -R option to the link + editor to embed a path within the library for run-time + library searches. A reasonable value for such systems would + be `-R$(libdir)'. + +SHLIB_LIBS Any additional libraries that shared libraries should be + linked against when they are created. + +SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when + generating the filename of the shared library. Many systems + use `so'; HP-UX uses `sl'. + +SHLIB_LIBVERSION The string to append to the filename to indicate the version + of the shared library. It should begin with $(SHLIB_LIBSUFF), + and possibly include version information that allows the + run-time loader to load the version of the shared library + appropriate for a particular program. Systems using shared + libraries similar to SunOS 4.x use major and minor library + version numbers; for those systems a value of + `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate. + Systems based on System V Release 4 don't use minor version + numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems. + Other Unix versions use different schemes. + +SHLIB_STATUS Set this to `supported' when you have defined the other + necessary variables. Make uses this to determine whether + or not shared library creation should be attempted. + +You should look at the existing stanzas in support/shobj-conf for ideas. + +Once you have updated support/shobj-conf, re-run configure and type +`make shared'. The shared libraries will be created in the shlib +subdirectory. + +If shared libraries are created, `make install' will install them. +You may install only the shared libraries by running `make +install-shared' from the top-level build directory. Running `make +install' in the shlib subdirectory will also work. If you don't want +to install any created shared libraries, run `make install-static'. + +Documentation +============= + +The documentation for the Readline and History libraries appears in +the `doc' subdirectory. There are three texinfo files and a +Unix-style manual page describing the facilities available in the +Readline library. The texinfo files include both user and +programmer's manuals. HTML versions of the manuals appear in the +`doc' subdirectory as well. + +Reporting Bugs +============== + +Bug reports for Readline should be sent to: + + bug-readline@gnu.org + +When reporting a bug, please include the following information: + + * the version number and release status of Readline (e.g., 4.2-release) + * the machine and OS that it is running on + * a list of the compilation flags or the contents of `config.h', if + appropriate + * a description of the bug + * a recipe for recreating the bug reliably + * a fix for the bug if you have one! + +If you would like to contact the Readline maintainer directly, send mail +to bash-maintainers@gnu.org. + +Since Readline is developed along with bash, the bug-bash@gnu.org mailing +list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains +Readline bug reports and fixes. + +Chet Ramey +chet@po.cwru.edu diff --git a/vendor/readline/USAGE b/vendor/readline/USAGE new file mode 100644 index 00000000..edc9f541 --- /dev/null +++ b/vendor/readline/USAGE @@ -0,0 +1,37 @@ +From rms@gnu.org Thu Jul 22 20:37:55 1999 +Flags: 10 +Return-Path: rms@gnu.org +Received: from arthur.INS.CWRU.Edu (root@arthur.INS.CWRU.Edu [129.22.8.215]) by odin.INS.CWRU.Edu with ESMTP (8.8.6+cwru/CWRU-2.4-ins) + id UAA25349; Thu, 22 Jul 1999 20:37:54 -0400 (EDT) (from rms@gnu.org for <chet@odin.INS.CWRU.Edu>) +Received: from nike.ins.cwru.edu (root@nike.INS.CWRU.Edu [129.22.8.219]) by arthur.INS.CWRU.Edu with ESMTP (8.8.8+cwru/CWRU-3.6) + id UAA05311; Thu, 22 Jul 1999 20:37:51 -0400 (EDT) (from rms@gnu.org for <chet@po.cwru.edu>) +Received: from pele.santafe.edu (pele.santafe.edu [192.12.12.119]) by nike.ins.cwru.edu with ESMTP (8.8.7/CWRU-2.5-bsdi) + id UAA13350; Thu, 22 Jul 1999 20:37:50 -0400 (EDT) (from rms@gnu.org for <chet@nike.ins.cwru.edu>) +Received: from wijiji.santafe.edu (wijiji [192.12.12.5]) + by pele.santafe.edu (8.9.1/8.9.1) with ESMTP id SAA10831 + for <chet@nike.ins.cwru.edu>; Thu, 22 Jul 1999 18:37:47 -0600 (MDT) +Received: (from rms@localhost) + by wijiji.santafe.edu (8.9.1b+Sun/8.9.1) id SAA01089; + Thu, 22 Jul 1999 18:37:46 -0600 (MDT) +Date: Thu, 22 Jul 1999 18:37:46 -0600 (MDT) +Message-Id: <199907230037.SAA01089@wijiji.santafe.edu> +X-Authentication-Warning: wijiji.santafe.edu: rms set sender to rms@gnu.org using -f +From: Richard Stallman <rms@gnu.org> +To: chet@nike.ins.cwru.edu +Subject: Use of Readline +Reply-to: rms@gnu.org + +I think Allbery's suggestion is a good one.

The +dnl default (if it is not specified or empty) is 'no-libtool'. +dnl INTLSYMBOL should be 'external' for packages with no intl directory, +dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. +dnl If INTLSYMBOL is 'use-libtool', then a libtool library +dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, +dnl depending on --{enable,disable}-{shared,static} and on the presence of +dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library +dnl $(top_builddir)/intl/libintl.a will be created. +dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext +dnl implementations (in libc or libintl) without the ngettext() function +dnl will be ignored. If NEEDSYMBOL is specified and is +dnl 'need-formatstring-macros', then GNU gettext implementations that don't +dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. +dnl INTLDIR is used to find the intl libraries. If empty, +dnl the value `$(top_builddir)/intl/' is used. +dnl +dnl The result of the configuration is one of three cases: +dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled +dnl and used. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 2) GNU gettext has been found in the system's C library. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 3) No internationalization, always use English msgid. +dnl Catalog format: none +dnl Catalog extension: none +dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. +dnl The use of .gmo is historical (it was needed to avoid overwriting the +dnl GNU format catalogs when building on a platform with an X/Open gettext), +dnl but we keep it in order not to force irrelevant filename changes on the +dnl maintainers. +dnl +AC_DEFUN([AM_GNU_GETTEXT], +[ + dnl Argument checking. + ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , + [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT +])])])])]) + ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , + [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT +])])])]) + define(gt_included_intl, ifelse([$1], [external], [no], [yes])) + define(gt_libtool_suffix_prefix, ifelse([$1], [use-libtool], [l], [])) + + AC_REQUIRE([AM_PO_SUBDIRS])dnl + ifelse(gt_included_intl, yes, [ + AC_REQUIRE([AM_INTL_SUBDIR])dnl + ]) + + dnl Prerequisites of AC_LIB_LINKFLAGS_BODY. + AC_REQUIRE([AC_LIB_PREPARE_PREFIX]) + AC_REQUIRE([AC_LIB_RPATH]) + + dnl Sometimes libintl requires libiconv, so first search for libiconv. + dnl Ideally we would do this search only after the + dnl if test "$USE_NLS" = "yes"; then + dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then + dnl tests.

Specifically, I've been using the perl +version Term::ReadLine::Gnu. It works great. + +Anyway, I've been playing around the alternate interface and I wanted +to contribute a little C program, callback.c, to you that you could +use as an example of the alternate interface in the /examples +directory of the readline distribution. + +My example shows how, using the alternate interface, you can +interactively change the prompt (which is very nice imo). Also, I +point out that you must roll your own terminal setting when using the +alternate interface because readline depreps (using your parlance) the +terminal while in the user callback. I try to demostrate what I mean +with an example. I've included the program below. + +To compile, I just put the program in the examples directory and made +the appropriate changes to the EXECUTABLES and OBJECTS line and added +an additional target 'callback'. + +I compiled on my Sun Solaris2.6 box using Sun's cc. + +Let me know what you think. + +Jeff +*/ + +#if defined (HAVE_CONFIG_H) +#include <config.h> +#endif + +#include <stdio.h> +#include <sys/types.h> + +#ifdef HAVE_UNISTD_H +#include <unistd.h> +#endif + +#include <termios.h> /* xxx - should make this more general */ + +#ifdef READLINE_LIBRARY +# include "readline.h" +#else +# include <readline/readline.h> +#endif + +/* This little examples demonstrates the alternate interface to using readline. + * In the alternate interface, the user maintains control over program flow and + * only calls readline when STDIN is readable. Using the alternate interface, + * you can do anything else while still using readline (like talking to a + * network or another program) without blocking. + * + * Specifically, this program highlights two importants features of the + * alternate interface. The first is the ability to interactively change the + * prompt, which can't be done using the regular interface since rl_prompt is + * read-only. + * + * The second feature really highlights a subtle point when using the alternate + * interface. That is, readline will not alter the terminal when inside your + * callback handler. So let's so, your callback executes a user command that + * takes a non-trivial amount of time to complete (seconds). While your + * executing the command, the user continues to type keystrokes and expects them + * to be re-echoed on the new prompt when it returns. Unfortunately, the default + * terminal configuration doesn't do this. After the prompt returns, the user + * must hit one additional keystroke and then will see all of his previous + * keystrokes. To illustrate this, compile and run this program. Type "sleep" at + * the prompt and then type "bar" before the prompt returns (you have 3 + * seconds). Notice how "bar" is re-echoed on the prompt after the prompt + * returns? This is what you expect to happen. Now comment out the 4 lines below + * the line that says COMMENT LINE BELOW. Recompile and rerun the program and do + * the same thing. When the prompt returns, you should not see "bar". Now type + * "f", see how "barf" magically appears?

It is a shared library that redirects calls to fgets(stdin) +to readline() via LD_PRELOAD, and it supports a custom prompt and list of +command names. Many people have asked me for this file, so I thought I'd +pass it your way in hope of just including it with readline to begin with. + +Best Regards, + +-Harold +*/ + +/****************************************************************************** +******************************************************************************* + + FILE NAME: fgets.c TARGET: libfgets.so + AUTHOR: Harold Levy VERSION: 1.0 + hlevy@synopsys.com + + ABSTRACT: Customize fgets() behavior via LD_PRELOAD in the following ways: + + -- If fgets(stdin) is called, redirect to GNU readline() to obtain + command-line editing, file-name completion, history, etc. + + -- A list of commands for command-name completion can be configured by + setting the environment-variable FGETS_COMMAND_FILE to a file containing + the list of commands to be used. + + -- Command-line editing with readline() works best when the prompt string + is known; you can set this with the FGETS_PROMPT environment variable. + + -- There special strings that libfgets will interpret as internal commands: + + _fgets_reset_ reset the command list + + _fgets_dump_ dump status + + _fgets_debug_ toggle debug messages + + HOW TO BUILD: Here are examples of how to build libfgets.so on various + platforms; you will have to add -I and -L flags to configure access to + the readline header and library files. + + (32-bit builds with gcc) + AIX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline -ltermcap + HP-UX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldld -lreadline + Linux: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline + SunOS: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lgen -lreadline + + (64-bit builds without gcc) + SunOS: SUNWspro/bin/cc -D_LARGEFILE64_SOURCE=1 -xtarget=ultra -xarch=v9 \ + -KPIC fgets.c -Bdynamic -lc -ldl -lgen -ltermcap -lreadline + + HOW TO USE: Different operating systems have different levels of support + for the LD_PRELOAD concept. The generic method for 32-bit platforms is to + put libtermcap.so, libfgets.so, and libreadline.so (with absolute paths) + in the LD_PRELOAD environment variable, and to put their parent directories + in the LD_LIBRARY_PATH environment variable. Unfortunately there is no + generic method for 64-bit platforms; e.g. for 64-bit SunOS, you would have + to build both 32-bit and 64-bit libfgets and libreadline libraries, and + use the LD_FLAGS_32 and LD_FLAGS_64 environment variables with preload and + library_path configurations (a mix of 32-bit and 64-bit calls are made under + 64-bit SunOS). + + EXAMPLE WRAPPER: Here is an example shell script wrapper around the + program "foo" that uses fgets() for command-line input: + + #!/bin/csh + #### replace this with the libtermcap.so directory: + set dir1 = "/usr/lib" + #### replace this with the libfgets.so directory: + set dir2 = "/usr/fgets" + #### replace this with the libreadline.so directory: + set dir3 = "/usr/local/lib" + set lib1 = "${dir1}/libtermcap.so" + set lib2 = "${dir2}/libfgets.so" + set lib3 = "${dir3}/libreadline.so" + if ( "${?LD_PRELOAD}" ) then + setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}:${LD_PRELOAD}" + else + setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}" + endif + if ( "${?LD_LIBRARY_PATH}" ) then + setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}:${LD_LIBRARY_PATH}" + else + setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}" + endif + setenv FGETS_COMMAND_FILE "${dir2}/foo.commands" + setenv FGETS_PROMPT "foo> " + exec "foo" $* + + Copyright (C)©2003-2004 Harold Levy. + + This code links to the GNU readline library, and as such is bound by the + terms of the GNU General Public License as published by the Free Software + Foundation, either version 2 or (at your option) any later version. + + The GNU General Public License is often shipped with GNU software, and is + generally kept in a file called COPYING or LICENSE.
