Colon separated datafile modifiers (used + for plot, splot, and fit) are not supported either. Arguments + not yet supported by the GUI generate messages printed in grey + text. + 5.

On recent Emacs (>= 23), +;; you may also want to turn on `gnuplot-tab-completion' so that the +;; TAB key does auto-completion on lines which are already +;; indented. (This just sets the Emacs variable `tab-always-indent' to +;; `complete' in Gnuplot buffers). +;; +;; If you need to turn context sensitivity on or off from Lisp code +;; for some reason, call the function +;; `gnuplot-context-sensitive-mode', which behaves like a minor mode. +;; +;; With `eldoc-mode' support, gnuplot-mode will show one-line syntax +;; hints automatically in the echo area. Whether eldoc-mode is active +;; or not, you can always pop up a longer description of syntax using +;; `gnuplot-help-function' (C-c C-/ or C-c M-h). ElDoc support also +;; requires an additional file of help strings, `gnuplot-eldoc.el', +;; which should be included in recent Gnuplot releases. If it didn't +;; come with your Gnuplot installation, you'll need to grab a recent +;; source distribution of Gnuplot from http://gnuplot.info, and use +;; the `doc2texi.el' program in the docs/ directory to create it. So +;; long as the file is on your Emacs load path somewhere it will be +;; loaded automatically when needed. +;; +;; You can customize gnuplot-mode to turn on eldoc mode automatically +;; using variable `gnuplot-eldoc-mode'. Simply calling `eldoc-mode' +;; will also work. +;; +;; Internal details +;; ================ +;; +;; Gnuplot's command language has a fair amount of syntactic +;; complexity, and the only way I could think of to support these +;; features was to do a complete parse of the command line. So that's +;; what this package does. Instead of building a parse tree, it +;; matches up until the token at point, and then either makes a list +;; of possible completions, or sets the variables `gnuplot-eldoc' and +;; `gnuplot-info-at-point' based on where it is in the grammar at that +;; point. +;; +;; The parsing/matching process happens in two phases: tokenizing +;; (`gnuplot-tokenize') and matching (`gnuplot-match-pattern'). In +;; order to be able to construct a full list of possible completions +;; via backtracking, the matching algorithm simulates a simple stack +;; machine with continuations. At byte-compile time, the PEG-like +;; grammar in S-expression notation (`gnuplot-grammar') is compiled +;; down into a vector of "machine code" for the parsing machine (see +;; `gnuplot-compile-pattern', `gnuplot-compile-grammar' and +;; `gnuplot-compiled-grammar'). This is complicated, but it seems to +;; work well enough, and it saves on the Emacs call stack. +;; +;; Compiling the grammar does require increasing `max-lisp-eval-depth' +;; modestly. This shouldn't cause any problems on modern machines, and +;; it only needs to be done once, at byte-compilation time. +;; +;; The parsing machine and compiler are partially based on the +;; description in Medeiros and Ierusalimschy 2008, "A Parsing Machine +;; for PEGs" (http://dl.acm.org/citation.cfm?doid=1408681.1408683). +;; +;; The pattern-matching language +;; ============================= +;; +;; The gnuplot-mode grammar (see `gnuplot-compiled-grammar') is a list +;; of rules (RULE PATTERN), with each pattern written in S-expression +;; notation as follows: +;; +;; any +;; Match any token +;; +;; name, number, string, separator +;; Match a token of the given type. "Separator" is semicolon, the +;; statement separator. +;; +;; Any other symbol +;; Match another named rule in the grammar. May be recursive. +;; +;; "STRING" +;; Match literally: a token with exactly the text "STRING". +;; +;; (kw KEYWORD ALIASES ...) +;; Match abbreviated Gnuplot keywords. KEYWORD can be a string or +;; a cons (PREFIX . SUFFIX). In the latter case, this pattern +;; will match PREFIX plus any number of characters from the +;; beginning of SUFFIX. Any literal string from ALIASES will +;; also match. The token-id of the matching token is mutated to +;; the canonical value of KEYWORD. +;; Example: +;; (kw ("linew" ."idth") "lw") matches "linew", "linewi", +;; ... "linewidth" as well as "lw". Any of these tokens will +;; appear as "linewidth" in subsequent processing. (This is +;; important for the "info-keyword" form, see below). +;; +;; The other pattern forms combine simpler patterns, much like regular +;; expressions or PEGs (parsing expression grammars): +;; +;; (sequence { (:eldoc "eldoc string") } +;; { (:info "info page") } +;; { (:no-info) } +;; PATTERN PATTERN... ) +;; Match all the PATTERNs in sequence or fail. Sequences can also +;; have optional ElDoc strings and info pages associated with +;; them; the innermost ElDoc or info page around point is the one +;; shown to the user. Alternatively, either property may be a +;; symbol, which should be a function to be called to get the +;; real value. Finally, if no ElDoc string is specified but the +;; variable `gnuplot-eldoc-hash' contains a value for the name of +;; the info page at point, that value is used as the ElDoc string +;; instead. +;; +;; For better readability, sequence forms can also be written as +;; a vector, omitting the `sequence': [PATTERN PATTERN ...] +;; +;; (either PATTERN PATTERN...) +;; Match the first PATTERN to succeed, or fail if none +;; matches. Like regexp `|'. +;; +;; (many PATTERN) +;; Match PATTERN zero or more times, greedily; like regexp +;; `*'. Unlike a regular expression matcher, the parsing machine +;; will not backtrack and try to match fewer times if a later +;; part of the pattern fails. This applies equally to the other +;; non-deterministic forms "either" and "maybe". +;; +;; (maybe PATTERN) +;; Match PATTERN zero or one times, like regexp `?'. +;; +;; (capture NAME PATTERN) +;; Match PATTERN, capturing the tokens in a capture group named +;; NAME. Capture groups are stored in `gnuplot-captures' +;; and can be retrieved using `gnuplot-capture-group'. This is +;; used to store the plotting style, which we need in order to +;; give the correct ElDoc string for "using" clauses, and for +;; info keywords (see below) +;; +;; (info-keyword PATTERN) +;; Match PATTERN, and use whatever the value of the first token +;; it matches is to look up info pages for this pattern. Most +;; Gnuplot info pages have the same name as the keyword they +;; document, so by using this we only have to put :info +;; properties on the few that don't, such as "set". +;; +;; For convenience, "many", "maybe", "capture" and "info-keyword" +;; wrap the rest of their arguments in an implicit "sequence" form, +;; so we can write (maybe "," expression) instead of +;; (maybe (sequence "," expression)) +;; +;; (delimited-list PATTERN SEPARATOR) +;; Match a list of PATTERNs separated by SEPARATOR. Sugar for: +;; (sequence PATTERN (many (sequence SEPARATOR PATTERN))) +;; +;; (assert LISP-FORM) +;; Evaluate LISP-FORM and fail if it returns NIL. We need this in +;; the patterns for "plot" and "splot" to check whether the +;; command at point should be parsed in parametric mode or +;; not. See `gnuplot-guess-parametric-p'. +;; +;; +;; Bugs, TODOs, etc. +;; ======================= +;; +;; It would be useful to complete on user-defined functions and +;; variables as well as built-ins. +;; +;; Completion probably will not work in continuation lines entered +;; into the gnuplot interaction buffer. +;; +;; It would be better to pop up longer syntax descriptions in a +;; temporary window, rather than making the echo area grow to fit +;; many lines. +;; +;; In ElDoc mode, we parse the whole line every time the user stops +;; typing. This is wasteful; should cache things in text properties +;; instead. +;; +;; The pattern matching engine uses backtracking, which can take +;; exponential time. So far it seems "fast enough" in actual use. +;; +;; The patterns don't really distinguish between "plot" and "splot" +;; for things like plot styles, binary arguments, etc. +;; +;; Some other the patterns are probably not quite right, especially for +;; things like abbreviated keywords, and features that I don't use +;; myself like "fit". Hopefully anyone bothered by this will submit +;; patches ;-) +;; +;; It would be possible to provide more helpful ElDoc strings for +;; sub-parts of complicated options like "cntrparam".

It supports features of recent +;; Gnuplot versions (4.4 and up), but should also work fine with older +;; versions. +;; +;; This version of gnuplot-mode has been tested mostly on GNU Emacs 23 +;; and 24, but should also work with older GNU Emacs versions back to +;; Emacs 21, and XEmacs 21. +;; +;; This mode offers several tools to help you compose your scripts, +;; including font-lock syntax colorization, a syntax table appropriate +;; to gnuplot, key bindings, pull-down menus, indentation, keyword +;; completions and variable customization using the Custom package. +;; Once the script is composed, there are several function for sending +;; some or all of the script to gnuplot. The interaction with the +;; gnuplot process is within a comint buffer. Plots can optionally be +;; displayed within Emacs. +;; +;; C-c C-l send current line to gnuplot +;; C-c C-v send current line to gnuplot and move forward 1 line +;; C-c C-r send current region to gnuplot +;; C-c C-b send entire buffer to gnuplot +;; C-c C-f send a file to gnuplot +;; C-c C-i insert filename at point +;; C-c C-n negate set option on current line +;; C-c C-c comment region +;; C-c C-o set arguments for command at point +;; S-mouse-2 set arguments for command under mouse cursor +;; C-c C-d read the gnuplot info file +;; C-c C-e show-gnuplot-buffer +;; C-c C-k kill gnuplot process +;; C-c C-u submit a bug report about gnuplot-mode +;; C-c C-z customize gnuplot-mode +;; M-tab or M-ret complete keyword before point +;; ret newline and indent +;; tab indent current line +;; C-c M-i toggle inline plot display in comint buffer +;; +;; With the exception of the commands for sending commands to Gnuplot, +;; most of the above commands also work in the Gnuplot comint buffer, +;; in addition to the following: +;; M-C-p plot the most recent script buffer line-by-line +;; M-C-f save the current script buffer and load that file +;; C-c C-e pop back to most recent script buffer +;; +;; These two functions are useful for starting up gnuplot-mode: +;; +;; M-x gnuplot-mode +;; start gnuplot-mode in the current buffer +;; +;; M-x gnuplot-make-buffer +;; open a new buffer (which is not visiting a file) and start +;; gnuplot-mode in that buffer +;; +;; Gnuplot-mode now includes context-sensitive support for keyword +;; completion and, optionally, eldoc-mode help text. See the +;; commentary in gnuplot-context.el for more information. If you +;; don't find it useful, it can be turned off by customizing +;; `gnuplot-context-sensitive-mode'. +;; +;; +;; --------------------------------------------------------------------- +;; +;; Other Lisp files used by gnuplot.el +;; +;; gnuplot-gui.el (written by Bruce): +;; Defines the GUI interface for setting setting arguments to +;; gnuplot options. This uses the widget package extensively. +;; +;; gnuplot-context.el (written by Jonathan, j.j.oddie@gmail.com) +;; Context-sensitive completion, help lookup and eldoc +;; strings for gnuplot buffers. Should be byte-compiled before +;; using. +;; +;; --------------------------------------------------------------------- +;; +;; This mode was inspired by the original gnu-plot-mode by Gershon +;; Elber, which is distributed with gnuplot itself and which dates +;; back to the early 90's. Although this mode encompasses the +;; functionality of the original, the two share no code and the +;; current implementation takes advantage of many features of modern +;; versions of Emacs and adheres (or so I intend) to the major mode +;; conventions described in the emacs-lisp reference for version 19 +;; and later. +;; +;; --------------------------------------------------------------------- +;; +;; Installation +;; ============ +;; +;; A recent version of this file can be found at +;; https://github.com/emacsorphanage/gnuplot/ +;; +;; To autoload gnuplot-mode on any file with gp extension, put this in +;; your .emacs file +;; (autoload 'gnuplot-mode "gnuplot" "gnuplot major mode" t) +;; (autoload 'gnuplot-make-buffer "gnuplot" "open a buffer in gnuplot-mode" t) +;; +;; Something like +;; (setq auto-mode-alist (append '(("\\.gp$" . gnuplot-mode)) +;; auto-mode-alist)) +;; is useful for having files ending in .gp start up in gnuplot-mode. +;; +;; Something like +;; (global-set-key [(f9)] 'gnuplot-make-buffer) +;; may be useful. This binds f9 to the function that opens a scratch +;; buffer (i.e. one that is not visiting a file) in gnuplot-mode. +;; This is handy for your quick 'n' dirty plotting chores. +;; +;; To use the `gnuplot-info-lookup-symbol' function, the file +;; gnuplot.info MUST be installed somewhere that info can find it. +;; This means you must either: +;; 1. Copy gnuplot.info to the normal info directory or +;; 2. Make sure info can find gnuplot.info by putting this in your +;; .emacs file: +;; (setenv "INFOPATH" +;; (concat (getenv "INFOPATH") ":" +;; (expand-file-name "/path/to/file"))) +;; where "/path/to/file" is the location of gnuplot.info +;; +;; This mode has been tested extensively with GNU Emacs 23 and 24, and +;; in a limited manner with GNU Emacs 22 and XEmacs 21. +;; +;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; + +;;; History: + +;; +;; 0.1 Jun 25 1998 Finished with initial release. +;; 0.2 Sep 4 1998 Added filename insertion, indentation, and +;; colorization/completion in comint buffer. <BR> +;; 0.2a Sep 11 1998 made `indent-line-function' buffer-local (whoops!) +;; and fixed some stuff in the installation script <BR> +;; 0.3 Sep 12 1998 include insertions menu <BR> +;; 0.3a Sep 14 1998 fixed bug finding info file if missing, fixed bug +;; starting font-lock, fixed bug re overwriting files in +;; installation script <BR> +;; 0.3b Sep 15 1998 Added (require 'info) to `(eval-and-compile' +;; clause, Added (kill-all-local-variables) to `gnuplot-mode', +;; altered order of:- +;; (provide 'gnuplot) +;; (run-hooks 'gnuplot-load-hook) +;; at the end of the file in case something in the load hook +;; requires gnuplot (oh not that old one again...), added +;; `gnuplot-comint-setup-hook', corrected `gnuplot-mark-active' +;; which caused an error to be raised by (mark) when the mark +;; was inactive <DB> Some changes to font-lock rules <LB>&<BR> +;; 0.4 Nov 14 1998 <BR> Use info-look for info interface.

Also, `gnuplot-keywords' (used +;; for help, keyword-completion, and hilit19 highlighting) is +;; now generated automatically. +;; 0.4a Nov 18 1998 <BR> info-look leaves a couple of really useless +;; buffers lying around so I cleaned them up.

Colon separated datafile modifiers (used + for plot, splot, and fit) are not supported either. Arguments + not yet supported by the GUI generate messages printed in grey + text. + 5.
