+;;; Commentary:
+;;
+;; This file provides a graphical user interface to setting arguments
+;; to gnuplot commands. Positioning point near a command and invoking
+;; `gnuplot-gui-set-options-and-insert' (C-c C-c or shift-mouse-2)
+;; will pop open a frame with widgets for setting the various
+;; arguments appropriate the the item that was near point. The goal
+;; is to provide point-and-click functionality to gnuplot-mode.
+;;
+;; gnuplot-gui is designed for gnuplot 3.7, but since much of 3.7 is
+;; backward compatible to 3.5, it will work well for that version
+;; also.
+;;
+;; gnuplot-gui.el was developed using Emacs 19.34 and is known to work
+;; on Emacs 20.x and XEmacs 20.x. I do not know what is the earliest
+;; version for which it will work, but I make no guarantees for
+;; versions before 19.34. Note that this makes heavy use of the
+;; widget package, so this will not work on Emacs 19.34 unless you
+;; install the widget package separately.
+;;
+;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
+;;
+;;; To do:
+;;
+;; Widgets I need:
+;; -- 'position: two or three comma separated numbers used to denote a
+;; position or a tic start/end/increment (see arrow,
+;; need a prefix)
+;; -- 'modifier: colon separated fields used for datafile modifiers
+;;
+;; command types which are currently unsupported or contain mistakes
+;; -- unsupported: cntrparam
+;; -- plot, splot, fit: rather lame
+;; -- label: position information missing
+;; -- label: font string handled in overly simple manner
+;; -- hidden3d: not really suited to 'list, but all options are exclusive...
+;; -- pointstyle argument to "set label"
+;;
+;; overall:
+;; -- continuation lines (ugh!)
+;; -- multiple frames end up displaying same window after setting options
+;;

+
+Each entry in the list is a cons cell of the form

+where OPTION is one of the recognized options in Gnuplot, either a
+command, something that is set, or a terminal type. Only those
+commands, set options, and terminal types that actually take arguments
+are in this associated list.
+
+ALIST is itself an associated list where each entry is of the form:
+
+ (TAG TYPE DEFAULT REST)
+
+TAG is the name used on the widget and indicates one of the options
+for this command, set option, or terminal type.
+
+TYPE is one of
+ 'list a menu-list of strings
+ 'list* a menu-list of strings with a prefix
+ 'number a number with an optional prefix
+ 'tag like number but must be the first argument
+ 'fontsize like number but must be the last argument
+ 'range a pair of numbers like [#,#] or [#:#]
+ 'pair a pair of numbers with no punctuation and a prefix
+ 'file a quoted string and a file browser
+ 'string a quoted string with an optional prefix
+ 'string* an unquoted string with a prefix
+ 'format a quoted string and an info-link to (gnuplot)format
+ 'labels an array as needed for xtics, ytics, etc
+ 'position 2 or 3 comma separated numbers with an optional prefix
+
+DEFAULT is the default value for this option. Note that the default
+for 'range and 'pair is a cons cell and the default for 'labels is a
+list. For most things, the best choice of DEFAULT is a string of
+white space or a cons cell of two strings of white space. Strings of
+white space are better defaults than empty strings or nil.
+
+The value of REST depends upon TYPE:
+
+ For 'list & REST is the list of options that will go into the
+ 'list* menu-button. This can also be a symbol which
+ evaluates to a list containing the options to go into
+ the menu-button. This list variable must contain the
+ DEFAULT.
+ For 'number REST is the prefix string (if it exists) for that number.
+ For 'range REST is the separator, \":\" for plot ranges and
+ \",\" for plot dimensions (see for example the tgif
+ terminal type)
+ For 'string & REST may a number denoting the width of the editable-text
+ 'string* field or it may be a string denoting a prefix. By
+ default, the width is half the width of the frame
+ and there is no prefix. It may be useful to
+ specify \"1\" when the input is a single character
+ as in 'set missing'.
+ For 'file REST determines the label placed before the file insertion
+ field. If non-nil, then TAG is used. If nil, then
+ the default \"File\" is used.
+ For 'position REST is the prefix and the number of comma separated numbers
+ For others REST is not used.
+
+Here is an example entry for the png terminal type:
+
+ (cons \"png\"
+ '((\"SIZE\" 'list \" \" \"small\" \"medium\" \"large\")
+ (\"COLOR\" 'list \" \" \"monochrome\" \"gray\" \"color\")))

+
+;;; Commentary:
+
+;;
+;; This is a major mode for composing gnuplot scripts and displaying
+;; their results using gnuplot. It is optimized for use with gnuplot
+;; 3.7 or one of the later patchlevels of "version 3.6". It should
+;; also work very handily with version 3.5. This mode offers several
+;; tools to help you compose your scripts, including syntax
+;; colorization using either font-lock or hilit19, 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.
+;;
+;; 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-h 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
+;; M-tab or M-ret complete keyword before point
+;; ret newline and indent
+;; tab indent current line
+;;
+;; Gnuplot-mode adds two key bindings to the comint buffer:
+;; M-C-p plot the current script buffer line-by-line
+;; M-C-f save the current script buffer and load that file
+;;
+;; 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
+;;
+;; ---------------------------------------------------------------------
+;;
+;; Other lisp files used by gnuplot.el
+;;
+;; info-look.el (comes with GNU Emacs 20):
+;; This provides the interface to the gnuplot-info file and provides
+;; on-line help and keyword completion functionality. The version
+;; of info-look.el that comes with version 20.2 of Emacs contains a
+;; bug that will impede its interaction with the gnuplot info file.
+;; You should use the version from the gnuplot-mode homepage
+;; instead. info-look is not distributed with XEmacs and so should
+;; be installed along with gnuplot-mode when using XEmacs.
+;;
+;; gnuplot-gui.el (written by Bruce):
+;; Defines the GUI interface for setting setting arguments to
+;; gnuplot options. This uses the widget package extensively.
+;;
+;; ---------------------------------------------------------------------
+;;
+;; 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
+;; http://github.com/bruceravel/gnuplot-mode/
+;;
+;; 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 had been tested extensively with Emacs 19.34 and 20.2 and
+;; XEmacs 20.3 and in a limited manner with Emacs 19.30 and XEmacs
+;; 19.14.

+
+;;; 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. No
+;; change to gnuplot-mode user interface, but cleaner code.
+;; With info-look, the help funcion works regardless of the
+;; version number of gnuplot. 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. Also fixed
+;; font-lock rules so that things in quotes get highlighted
+;; correctly and the surrounding text is unhighlighted. Fixed
+;; up font-lock rules for plot and splot. Added
+;; `gnuplot-send-line-and-forward' as suggested by <MD>.
+;; 0.4b Nov 21 1998 <BR> added toolbar for xemacs -- see file
+;; gnuplot-toolbar.el. fixed error message in plot line
+;; function when line is empty. option added to display the
+;; comint buffer showing the gnuplot process in a separate
+;; frame
+;; 0.4c Minor stuff: Nov 30 1998 <BR> fixed highlighting in comint
+;; buffer. fixed frame behavior. added "[:]" to range
+;; insertions. added :link to defgroup. Dec 1 1998 <BR> fixed
+;; some mismatched defcustoms. added a few lines to suppress
+;; some compile-time warnings. Dec 3 1998 <BR> Fixed behavior
+;; of filename insertion function. Added more :links to
+;; defgroup.
+;; 0.4d Dec 6 1998 <BR> Added function gnuplot-setup-info-look and
+;; variable gnuplot-info-hook to handle various versions of the
+;; gnuplot info file.
+;; 0.4e Dec 12 1998 <BR> Split up gnuplot-insertions-menu for ease of
+;; custimization, put menubar initialization in a function.
+;; 0.4f Dec 14 1998 <BR> defcustom the insertions submenus, add
+;; gnuplot-insertion-menu-flag, intelligent Makefile knows
+;; which info-look to compile
+;; 0.5 Dec 27 1998 <BR> wrote initial draft of gnuplot-gui.el,
+;; included it in insertions menu and in `gnuplot-insert'.
+;; Negate option function, bound to C-c C-n. Dec 29 1998 <BR>
+;; C-c C-h with no response goes to Commands menu. Transparent
+;; toolbar icons. Replace kw-compl with a simple completion
+;; function. Put gnuplot-toolbar code in gnuplot.el.
+;; 0.5a Jan 23 1999 <BR> send file uses the load command. add
+;; gnuplot-plot-from-comint and
+;; gnuplot-save-and-plot-from-comint and keybindings in the
+;; comint buffer. do (process-kill-without-query
+;; gnuplot-process nil). `gnuplot-negate-option' checks if set
+;; option has a negated form.
+;; 0.5b `gnuplot-kill-gnuplot-buffer' made more robust. fixed a bug
+;; in `gnuplot-plot-from-comint'. fixed description of
+;; gnuplot-faces group.
+;; 0.5c update copyright information, update gpelcard
+;; 0.5d Mar 20 1999 <BR> adopt installation materials from <LH>. Add
+;; some support for hidden3d. Use constants in types alists in
+;; gui. Various other minor improvements to the types alists.
+;; 0.5e Apr 6 1999 <BR> at the suggestion of <SE> I did away with the
+;; gnuplot-which-highlight variable and revamped how
+;; colorization gets turned on. This is a bit tricky since I
+;; want it to work with font-lock under emacs and xemacs and
+;; with hilit19. Apr 11 1999 <BR> insert space at end of
+;; unique completion. add a few GUI types, rewrite some stuff
+;; in the GUI interface. primitive support for plot, splot,
+;; and fit. Fixed completion in file widget.
+;; 0.5f May 15 1999 <BR> Add pgnuplot.c and Win9x install instructions
+;; to the distribution. Fixed a defface bug. Added
+;; `gnuplot-keywords-when' allowing deferral of parsing the
+;; info file.
+;; 0.5g May 27 1999 <BR> Fixed font-locking of strings and
+;; comments. Figure out gnuplot-version number from startup
+;; message and set `gnuplot-echo-command-line-flag'
+;; accordingly. Added `gnuplot-program-version' variable.
+;; Check that font-lock is actually a feature, as suggested by
+;; <KL>
+;; 0.5h Aug 15 1999 <BR> Added `gnuplot-determine-gnuplot-version' so
+;; that the gnuplot version number and `comint-process-echos'
+;; actually get set correctly. Actually, the first time
+;; something is plotted, the echoing might not work, but the
+;; second time it will.
+;; 0.5i Sep 2 1999 <BR> Once again changed how
+;; `comint-process-echos' gets set. Maybe I got it right this
+;; time? Also fixed certain situations where the info file
+;; did notget properly loaded (insertion with info toggle on
+;; and info button in GUI).
+;; 0.5j Sep 9 1999 <BR> Do a more robust check for the gnuplot
+;; process before killing the gnuplot buffer, as suggested by
+;; <SE>.
+;; 0.5k Sep 22 1999 <BR> make `gnuplot-send-line-and-forward' skip
+;; over blank and comment lines as suggested by <SE>. Jan 10
+;; 2000 Bound C-c C-j to `gnuplot-forward-script-line'.
+;; 0.5l Nov 16 2000 <BR> support for pm3d in gnuplot-gui and in plot
+;; options insertions menu. mentioned pm3d in gpelcard. gui
+;; support for x11 pm3d and vgagl terms.
+;; `gnuplot-negate-option' works with new syntax.
+;; 0.5m Nov 17 2000 <BR> add colorization and gui support for new
+;; commands in 3.8. gui support for emf term. gui support for
+;; new "set style" syntax. much better scheme for determining
+;; gnuplot version number + make better use of it.
+;; 0.5n Jan 4 2001 <BR> corrected a serious problem interacting with
+;; speedbar
+;; 0.5o skipped
+;; 0.5p Mar 14 2001 <BR> fixed problem with toolbar creation and
+;; speedbar clicking
+;; 0.5q May 30 2001 <BR> added font-lock bindings for words associated
+;; with plotting
+;; 0.5r Oct 17 2001 <BR> Incorporate two suggestions by <RF>, bind
+;; C-c C-c to comment-region and C-c C-o to the GUI, also make
+;; C-c C-l respect continuation lines
+;; April 12, 2002 <BR> added feature to trim length of gnuplot
+;; process buffer
+;; 0.5s Jun 7 2002 <BR> Yet again changed how `comint-process-echos'
+;; gets set. It really needs to be nil on NTEmacs 21.1 or
+;; comint gets stuck in an infinate loop.
+;; 0.5t Sep 16 2002 <BR> Fixed a problem with C-c C-v jumping
+;; forward 2 lines at a time
+;; 0.6.0 Dec 13 2002 <BR> Changed numbering scheme to accommodate
+;; gnuplot packaging requirements
+;; 0.6.1 Sep 13 2011 <BR> Moved to github, updated contact info

+The insertions menu is composed of several sub-menus. The variables

+ `gnuplot-insertions-adornments'
+ `gnuplot-insertions-plot-options'
+ `gnuplot-insertions-terminal'
+ `gnuplot-insertions-x-axis'

+ `gnuplot-insertions-parametric-plots'
+ `gnuplot-insertions-polar-plots'

+These variables can be customized by the user. For example, there are
+many terminal types which are not in the terminal submenu but which
+may be compiled into a user's copy of gnuplot.
+
+Each of these variables is a list whose first element is a string and
+all the rest are vectors as described in the document string for
+`easy-menu-define'. The callback used throughout these menus is
+`gnuplot-insert' which inserts the appropriate set expression and,
+optionally, looks up that item in the gnuplot info file.
+
+The easiest way to customize the submenus is to use the custom
+package. Just type \\[gnuplot-customize] and follow your nose.
+
+You can also add new items to any of these sub-menus by adding to the
+`gnuplot-load-hook' in your .emacs file. Here is an example of adding
+the \"regis\" terminal type to the terminal sub-menu:
+

+ "Major mode for editing and executing GNUPLOT scripts.
+This was written with version 3.7 of gnuplot in mind but it should
+work fine with version 3.5 and the various 3.6 beta versions.
+
+Report bugs in `gnuplot-mode' using \\[gnuplot-bug-report].
+
+ ------O------
+
+The help functions, keyword completion, and several other features
+depend upon having the info file properly installed. The info file
+can be made in the document directory of the gnuplot distribution or
+is available at the `gnuplot-mode' web page:
+ http://github.com/bruceravel/gnuplot-mode/
+
+If the help function does not work properly, you may have an older
+version of the gnuplot info file. Try the suggestion in the document
+string for the variable `gnuplot-info-hook'. See the `gnuplot-mode'
+web page for more details.
+
+ ------O------
+
+There are several known shortcomings of `gnuplot-mode', version 0.5g
+and up. Many of the shortcomings involve the graphical interface
+\(refered to as the GUI) to setting arguments to plot options. Here is
+a list:
+
+ 1. Currently there is no way for `gnuplot-mode' to know if information
+ sent to gnuplot was correctly plotted.
+ 2. Indentation is sometimes a bit flaky.
+ 3. \"plot\", \"splot\", and \"fit\" are handled in the GUI, but are
+ a bit flaky. Their arguments may not be read correctly from
+ existing text, and continuation lines (common for plot and splot)
+ are not supported.
+ 4. The GUI does not know how to read from continuation lines.
+ 5. Comma separated position arguments to plot options are
+ unsupported in the GUI. 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.
+ 6. The GUI handling of \"hidden3d\" is flaky and \"cntrparam\" is
+ unsupported.
