These utilities, most of which operate on files, are +summarized later in this document. A general discussion of files in +the IRAF system follows. The reader is assumed to have some familiarity +with the IRAF command language (CL). + + +.sh +Virtual File Names + + File names may be specified in a machine independent fashion, or with +OS dependent pathnames. A Virtual File Name (VFN) has the following form: + + +.nf + ldir$root.extn + +where + + ldir logical directory or device name + root root or base file name + extn extension denoting the type of file +.fi + + +The LDIR and EXTN fields are optional. The ROOT and EXTN fields may contain +up to 20 characters selected from the set [a-zA-Z0-9_.+-#]. The EXTN field +may not exceed three characters. The EXTN field is separated from the ROOT +by the character "." (dot). If the ROOT field contains one or more occurrences +of the dot character, the final dot delimited field is understood to be +the extension. + +Logical directories are defined in the CL, using the SET command to associate +an OS dependent pathname with a keyword in the environment table. Logical +directory prefixes are recursively expanded. + +A number of standard logical directories and devices are defined by the CL +at startup time. Additional logical directories are defined by applications +packages upon entry, and become undefined when dictionary space is reclaimed +on exit from the package. The user may override environment definitions at +will, by issuing SET commands to redefine environment variables. + + +.sh +File List Templates + + Whenever it makes sense, the IRAF utilities are set up to process a list +of files, rather than a single file. In the descriptions of the standard +utilities in the next section, "files" is a template or pattern specifying +a list of files to be processed in some way. The template is a string type +parameter to the CL, which is expanded by a procedure (CLGFIL) in the +compiled systems or applications task into an EOF terminated list of files. + +A template may consist of one or more file names, directory names, +list file names, or patterns. List elements are delimited by commas. +A list file is denoted by prepending the character "@" to the pathname +of the list file. A pattern may be applied to the contents of either +a list file or a directory. The pattern is separated from the list file +or directory name by the character "$". A pattern all by itself is +applied to the current directory. Either logical or OS dependent +pathnames may be used. + +A list element may refer only to a single directory. Thus, one cannot +specify a pattern such as "*/*.x", as is possible in UNIX. + +Some examples of templates follow: + +.nf + file + "file1, file2" + "*.x" + "[A-Z]*, *.com, ../$, ../fio/$*.x, lib$*.h, file, @list$*.vs" + "sia1:[iraf.lib]$*.h, uparm$cl_*.par" +.fi + +The magic filenames "STDIN", "STDOUT", and "STDERR" have a special +meaning. Passing one of these special filenames to a task causes +the named stream to be "reopened", transparently to the applications +program. Thus, for example, one can reference "STDIN" in a template, +and the applications program will read from the standard input when +it opens the corresponding file in the template. + +For example, + + cl> concat "file1, @STDIN, STDIN, file2", > ofile + +concatenates the file "file1", the contents of the files named in the +standard input (until the first EOF), the contents of the standard input +itself (until the second EOF), and the contents of the file "file2", +placing the output in the file "ofile". + + +.sh +File Protection and Clobber + + The IRAF file interface (FIO) provides file protection and synchronization +facilities, under control of user definable environment variables. + +File "clobber" refers to the overwriting of an existing file when a new +file of the same name is created as an output file. If "clobber" is +defined as "no" in the environment, an IRAF task will abort if a new file +would clobber an existing file. If file clobber is enabled, FIO will try +to overwrite the old file, and will abort if it cannot do so. + + cl> set clobber = "yes" + +More explicit file protection is provided by the CL commands PROTECT and +UNPROTECT. A protected file cannot be deleted, accidentally or otherwise, +until the protection has been removed with the UNPROTECT command or system +call. + +A final form of file protection is provided to prevent a file from being +clobbered which is already open by a task. Thus, "COPY file,file" will +abort when FIO discovers that "file" is already opened for reading. This +holds even if file clobber is enabled. + + +.sh +File Synchronization + + File synchronization is useful when a process requires exclusive access +to a file which is already open for exclusive access by another process. +When this situation occurs, the second task may abort with a message stating +that it cannot access the file, or the task may wait for the file to become +available. File waiting is especially important for batch processes. + + cl> set file_wait = "yes" + +The file wait option is controlled by the "file_wait" variable in the +environment. If file waiting is enabled, and a process finds that it +has to wait to access a file, a warning message will be printed on the +standard error output before the affected process goes to sleep. +.endhelp diff --git a/pkg/system/doc/allocate.hlp b/pkg/system/doc/allocate.hlp new file mode 100644 index 00000000..66d3353f --- /dev/null +++ b/pkg/system/doc/allocate.hlp @@ -0,0 +1,52 @@ +.help allocate Jan86 system +.ih +NAME +allocate -- allocate a device +.ih +USAGE +allocate device +.ih +PARAMETERS +.ls device +The device to be allocated. +.le +.ih +DESCRIPTION +\fBAllocate\fR allocates a device for exclusive access by one user, and +readies the device for i/o by some other program.

To get a hardcopy of the manual page on the printer, the output +may be redirected to the line printer, as follows: + + pl> help graph | lprint +.ih +DESCRIPTION +The function of the \fBhelp\fR program is to perform a depth first search +of the help database \fIhelpdb\fR, printing help for all packages and modules +matching the template. By default the standard IRAF help database is searched, +but any other help database may be searched if desired. A help database is +precompiled with the \fBmkhelpdb\fR program to speed up runtime searches for +help modules. The standard IRAF help database contains the documentation and +source for all CL programs and system and math library procedures installed +in IRAF. + +A help template is a string type parameter to the CL. The form of a template +is a list of patterns delimited by commas, i.e., + + "pattern1, pattern2, ..., patternN" + +The form of a pattern is + + package_pattern.module_pattern + +If the "." is omitted \fImodule_pattern\fR is assumed. The standard pattern +matching meta-characters, i.e., "*?[]", are permitted in patterns. +Simple patterns are assumed to be abbreviations. + +.ih +GUI OPERATION + +The GUI component of the task is a front-end to the IRAF +.hr system.help \fBhelp\fR +task which provides on-the-fly conversion of help documents to HTML for +presentation in the GUI or formatted PostScript for hardcopy. +The GUI is started by setting the +.hr #l_device \fIdevice\fR +parameter to the special value \fIgui\fR, it is only available when using +an XGterm window to start IRAF and assuming the \fIstdgraph\fR environment +variable is set to \fRxgterm\fR. + +Help pages may be loaded on the command line, through use of a +file browser, or by navigating the help databases using a familiar CL +package menu scheme. It also features a search capability similar to the +.hr system.references \fBreferences\fR +task and a complete history mechanism. + +When invoked with no command line arguments the task starts as a browser +and the user is presented with a GUI that has the toplevel CL package menu +in the upper navigation window. The main display window below will contain +any help page specified in the +.hr #l_template template +parameter or loaded on +the command line by specifying the +.hr #l_template template +and +.hr #l_file_template file_template +parameters. If the +.hr #l_search search +parameter is enabled the +.hr #l_template template +is taken to be a search phrase and the database is searched for tasks +matching the keyword and the GUI will appear with the search panel mapped +so the user can select the task help to +view. When no +.hr #l_template template +is given the main display window will start with the page specified by the +.hr #l_home home +parameter, this can be a user-defined HTML file giving links to specific tasks +(see below for details) or if +.hr #l_home home +is empty the display will contain the online help for the task. + +The first time the task is run, or whenever the help database is updated, +a quick reference file (specified by the task +.hr #l_quickref quickref +parameter) and package menu file will be created in the user's \fIuparm\fR +directory to speed up help searching and subsequent startups of the task. + +.ih +NAVIGATING THE HELP SYSTEM +When run as a GUI browser \fIHELP\fR works very much like any WWW browser. +The top panel is a list widget that will always contain a CL package listing, +at startup this will be the toplevel \fI"Home"\fR package menu one would see +when first logging into the CL containing the core system packages, NOAO +package, and any site-specific external package, or in the case of starting +with a specific task it will be the parent package for the task. Additionally, +system documents for the +.hr os \fBos\fR +HSI routines and the +.hr sys.imfort \fBimfort\fR +and +.hr math \fBmath\fR +interfaces will be available in the \fIHome\fR package although +these are programmatic interfaces and not tasks which can be executed. + +New packages or task help pages are loaded by selecting an item from the +package menu list using the left mouse button. If the requested item is a +package, the menu listing will change as though the package were loaded in +the CL, and the help display panel will contain a listing of the package +tasks with a one-line description for each task such as would be seen with +a \fI"help <package>"\fR command using the standard task. New items may then +be selected using either the menu list or links in the display panel. If the +item is a task, the help page for the task will appear in the display panel. +In either case new pages may be selected from the menu listing. + +Specific help documents may also be requested by entering the task/package +name in the \fBTopic\fR text widget above the menu list. As when selecting +from the package menu list, items selected this way will cause the menu +list to change to the package menu for the parent package if the item is a +task (displaying the help page in the display panel) or the package menu +if the item is a package (displaying the one-liner package listing in the +display panel). + +Using the \fBBack\fR button will revert to the previous page in the history +list which will either be the previously loaded package or help page. +Similarly, selecting the \fBForward\fR button will move the next page further +down in the history list, either button will become insensitive when the +end of the list on either end is reached. Selecting the \fBUp\fR button will +cause the browser to immediately jump up the previous package, skipping +over any help pages that were loaded in between. The \fBHome\fR button will +cause the default homepage (either the user-defined page if specified by the +task \fIhome\fR parameter or the online help) to be displayed. Browsing +in this way can also be done using the navigation menu created by hitting +the right mouse button while in the main display panel. + +Users can also jump to specific pages in the history list using the +\fBHistory\fR button on the main menubar. The right column of the menu +will indicate whether the item is a task, package, internal link or a text +file. The history list is truncated at about 40 entries in the menu but +the user may work back incrementally by selecting the last item of the +menu, after which the History button will display the previous 40 entries. +The history list may be cleared except for the current page by selecting +the \fIClear History\fR menu item. + +.ih +BROWSING A HELP DOCUMENT +Once a help page is loaded the middle menubar above the display panel +will change to activate widgets based on the position within the history +list and options available for a particular page. The left-most group +of buttons are the standard navigation buttons described above. +The middle group of buttons contains the \fBSections\fR and +\fBParameters\fR buttons which are used to browse within a help document. +The \fISections\fR button is a menu listing all of the sections found +within a help page, allowing the user to jump to a specific section +rather than scrolling through the entire document. The \fISections\fR +menu is also available using the middle mouse button from the +main display area. The \fIParameters\fR button is similarly a menu +listing of all task parameter help sections found within the document. +Both or either of these buttons will become insensitive when no section +or parameter information is found in the document. + +The right-most group of buttons represent the various help options available +for each page. The default is to get the task help, however help pages +may have an associated \fBsource\fR file or \fBsysdoc\fR (e.g. if the task is +a CL script there may be a pointer to the script source itself, or a package +may have a general overview document listed as the system document). Once +a help page is loaded these buttons will change become sensitive if that option +is available, simply select the button to view the option. Selecting the +\fBFiles\fR button will bring up a panel listing all the files associated +with a particular help topic. When a help topic is selected and an option is +defined but the file does not exist, the options button will display a yellow +diamond icon even if the button is insensitive, a green icon indicates the +currently selected option. This feature may be disabled by selecting the +"Show missing files" item from the main menubar \fBOptions\fR menu. + +.ih +SEARCHING +Searching the help database is done by selecting the \fBSearch\fR button +from the main menubar to bring up the search panel. Users may then enter +one or more keywords into the \fBTopic\fR field at the bottom of the panel +and initiate the search with either a carriage return or hitting the +\fISearch\fR button just beside it. The panel will then show a list of all +tasks and packages which match the search phrase along with a one-line +description of the task. Help pages may be displayed by selecting either the +task or package link with the left mouse button, in both case the package +menu list on the main help window will be updated to list the package +contents allowing other tasks from that package to be selected in the normal +way. + +By default the exact phrase entered in the topic window will be used for the +search. This can be relaxed by toggling the "Require exact match" button +at the top of the panel. For example, to search for all tasks matching +\fIeither\fR the keyword "flat" or "field" turn off the exact match +toggle and the search will return not only tasks matching "flat field" but +also any task description containing only one of the words such as the +VELVECT task which plots velocity \fIfield\fRs. + +Within a help document itself one can search for a string by selecting +the \fBFind\fR button from the main menubar to bring up a panel used to +enter the search string. When the text is entered the main display +window will reposition itself and highlight the text found within the +document. Searches can be repeated and will wrap around the document +automatically, searches can be done either forward or backward through +the text and may be case insensitive. + +.ih +USER_DEFINED HOME PAGES +By default the \fIhelp\fR GUI will start with the online help page displayed +in the main help window. The user can change this by setting the task +\fBhome\fR parameter to be a path to any valid file. This file may be plain +text, a help document in LROFF format which will be converted to HTML for +display, or a native HTML document. + +HTML files may contain URLs of the form +.nf + \fB<a href=\fI[package.]task\fB>\fIurl_text\fB</a> +.fi + +where \fIurl_text\fR is the text to appear in the window and the URL itself +consists of an optional package and task name delimited by a period. For +example, to create a link to the +.hr onedspec.splot \fBsplot\fR +task in a document one would use the URL +.nf + \fB<a href=onedspec.splot>splot</a>\fR +.fi + +In this way users can create a homepage which serves as a \fI"bookmark"\fR +file or index of shortcuts to the most commonly accessed help pages. + +.ih +LOADING FILES +Text files may be loaded on the command line when starting the task by +specifying the filename and setting the +.hr #l_file_template file_template +task parameter. The named file +will be searched for a \fI.help\fR LROFF directing indicating it contains +a help block that will be converted to HTML for display. If no help +block is found the file will be displayed as-is, meaning existing +HTML documents can be loaded and will be formatted correctly. + +Once the task is running users may load a file by selecting the \fBOpen +File...\fR menu item from the main menubar \fBFile\fR menu or the +right-mouse-button menu from within the main display area. This will +open a file browser allowing users to change directories by using the +navigation buttons at the top of the panel, or selecting items from the +leftmost directory listing. Selecting a file on the rightmost list will +cause it to be loaded and automatically formatted if it contains a help +block. The file list may be filtered to select only those files matching +a particular template by changing the \fBFilter\fR box at the top of +the panel. Filenames or directories may be entered directly using the +\fBSelection\fR box at the bottom of the panel. + +.ih +SAVING FILES +Once a file has been loaded in the browser it may be saved to disk as +either \fIsource\fR (i.e. the original LROFF file if that was converted +for the display, or whatever file is currently displayed regardless of +format), \fItext\fR to save formatted plain text such as that produced +by the standard \fBhelp\fR task, \fIHTML\fR to save the converted HTML +used in the display, or \fIPostScript\fR to save formatted PostScript of +the document such as that sent to the printer using the \fBPrint\fR +button. Not all options will be available depending on the format of the +input text, unavailable options will be insensitive in the GUI. + +The \fBSave\fR panel is opened by selecting the \fBSave As...\fR menu +item from the main menubar \fBFile\fR menu or the right-mouse-button +menu from within the main display area. The file browser operates the +same as when loading images, the only difference is that file selection +simply defines the filename to be used and does not cause the save to +occur automatically. Users can overwrite existing files by selecting the +\fIOptions\fR toggle at the bottom of the panel. + +.ih +HARDCOPY OUTPUT AND SAVING DISK FILES. +Help pages may be output to any configured IRAF printer by selecting the +main menubar \fBPrint\fR button to bring up the print panel. Task help pages +will be converted to formatted PostScript and may be sent to either a +printer or saved to disk depending on the selection made in the printer +panel. If the printer name is set to the special value \fI"printer"\fR then +the device named by the CL \fIprinter\fR environment variable will be used. +When saving to disk files the default action is to save to a filename whose +name is the task name plus a ".ps" extension. Either of these are changeable +within the GUI as is the default page size to be used when generating the +PostScript. + +The main menubar \fBFile\fR button can also be used to bring up the file +browser in order to save the current document to disk. Help pages may be +saved as either the origin LROFF source for the file, formatted text as you +would get from the standard help task, HTML as is displayed in the GUI, or +formatted PostScript. The choice of formats is dictated by the type of file +being displayed (e.g. you cannot save PostScript of a program source). + +.ih +LROFF DIRECTIVE EXTENSIONS FOR HTML +To better support HTML links within documents and to other help pages two +new directives have been added to the LROFF text formatter. These are +\fB.hr\fR to specify a link (an HTML \fIHREF\fR directive) and \fB.hn\fR +to specify a name (an HTML \fINAME\fR directive). The syntax for these are +as follows: +.nf + + \fB.hn\fI <name>\fR + \fB.hr\fI <link> <text> \fR +.fi + +where \fI<name>\fR is the destination name of an internal link, \fI<link>\fR +is the URL of the link to be created, and \fI<text>\fR is the text to be +displayed in the HTML. The URL syntax is either a '#' character followed +by a destination name, a simple \fItask\fR name or \fIpackage\fR name, +or a \fIpackage.task\fR pair giving a more precise task. For internal links +the current document is repositioned so the name is at the top of the display, +for task help links new help pages will be loaded in the browser. + +These directives are ignored when converting the LROFF to either formatted +plain text or PostScript. + +.hn examples_target +.ih +GUI EXAMPLES +1) Start \fIhelp\fR as a GUI browser: +.nf + + cl> help dev=gui +.fi + +2) Begin by searching for the phrase 'gauss', tasks and packages may be +selected from the search panel which will appear when the task starts: +.nf + + cl> help gauss dev=gui search+ +.fi + +3) Load an LROFF help page in the browser at startup +.nf + + cl> help mytask.hlp dev=gui file+ +.fi + +.ih +EXAMPLES + +1.

Pages are normally broken when the screen fills, but may also +be delimited by form feed characters embedded in the input text. +A prompt is printed after each page of text naming the current file, +showing the percentage of the file which has been displayed, and the numeric +order of the file within the file list if a file template was given. + +When the end of page prompt is displayed any of the following command +keystrokes may be entered.

For example, ":!cl" will temporarily suspend the +pager, allowing CL commands to be entered until the command "bye" is entered, +causing execution of the pager to resume. Note that since the \fIpage\fR +task resides in the system process \fIx_system.e\fR, it will be necessary +for the CL to connect a second system process if the command issued calls +another task in the system package, since the first system process will +still be running, i.e., executing the \fIpage\fR task. This is harmless, +but the second process may be removed from the process cache with +\fIflprcache\fR if desired, after exiting the original \fIpage\fR task. + +The sequence ":/" followed by a pattern will cause the current input stream +to be searched for the next occurrence of the pattern given. A pattern once +entered is retained indefinitely and may be used in subsequent searches by +typing the single keystroke `n', without need to reenter the pattern. +Searching stops at the end of the current file, requiring a `.' to wrap back +around to the beginning of the file, or a `N' to advance to the next file. + +The \fI:file\fR command is used to change the current position within the +file list specified by \fIfiles\fR, and may not be used to page a file not +specified in the initial template. Note that the filename may be abbreviated, +and that searching stops with the first file lexically greater than or equal +to the given string (hence ":file x" might return file "y"). + +The \fI:line N\fR command may be used to randomly position to the indicated line +within the current file. If the line number argument N is preceded by a plus +or minus the argument is taken to be an offset from the current position. + +The \fI:spool\fR command is used to spool output to a file. Each time a +file line is printed on the screen, it is appended to the named file as well. +One can interactively position to the desired line of the file and then turn +on spooling to extract a portion of the file or stream being displayed. +A subsequent \fI:spool\fR command with no filename will turn spooling off. +Issuing a \fI:spool\fR to begin spooling on a new file when already spooling +to some other file will cause the old spool file to be closed. +.ih +EXAMPLES + +1.

If no \fIfname\fR is given, +a filename is constructed from the last part of the URL (i.e. +characters trailing any of the '?', '/', or '&' delimiters). Because +the URL may not point to a static file, use of the \fIfname\fR parameter +is recommended. + +If the \fIuse_cache\fR parameter is set, the URL will only be downloaded if +it does not already exist in the file cache pointed to by the \fIcache\fR +parameter, otherwise the cached file will be copied to the output filename. +The \fIextn\fR parameter may be to used to force a specific file extension +to be appended to the filename in the cache, this allows a URL to be passed +to a task and treated as if it were a file of a specific type. + +.ih +EXAMPLES + +1.
