93 ;; CUSTOMIZATION:
94 ;; =============
95 ;;
96 ;; IDLWAVE has extensive customize support - so if you want to learn
97 ;; about the variables which control the behavior of the mode, use
98 ;; `M-x idlwave-customize'.
99 ;;
100 ;; You can set your own preferred values with Customize, or with Lisp
101 ;; code in .emacs. For an example of what to put into .emacs, check
102 ;; the TexInfo documentation or see a complete .emacs at
103 ;; http://idlwave.org.
104 ;;
105 ;; KNOWN PROBLEMS:
106 ;; ==============
107 ;;
108 ;; IDLWAVE support for the IDL-derived PV-WAVE CL language of Visual
109 ;; Numerics, Inc. is growing less and less complete as the two
110 ;; languages grow increasingly apart. The mode probably shouldn't
111 ;; even have "WAVE" in it's title, but it's catchy, and required to
112 ;; avoid conflict with the CORBA idl.el mode. Caveat WAVEor.
113 ;;
114 ;; Moving the point backwards in conjunction with abbrev expansion
115 ;; does not work as I would like it, but this is a problem with
116 ;; emacs abbrev expansion done by the self-insert-command. It ends
117 ;; up inserting the character that expanded the abbrev after moving
118 ;; point backward, e.g., "\cl" expanded with a space becomes
119 ;; "LONG( )" with point before the close paren. This is solved by
120 ;; using a temporary function in `post-command-hook' - not pretty,
121 ;; but it works.
122 ;;
123 ;; Tabs and spaces are treated equally as whitespace when filling a
124 ;; comment paragraph. To accomplish this, tabs are permanently
125 ;; replaced by spaces in the text surrounding the paragraph, which
126 ;; may be an undesirable side-effect. Replacing tabs with spaces is
127 ;; limited to comments only and occurs only when a comment
128 ;; paragraph is filled via `idlwave-fill-paragraph'.
129 ;;
130 ;; Avoid muti-statement lines (using "&") on block begin and end
131 ;; lines. Multi-statement lines can mess up the formatting, for
132 ;; example, multiple end statements on a line: endif & endif.
133 ;; Using "&" outside of block begin/end lines should be okay.
134 ;;
135 ;; Determining the expression at point for printing and other
136 ;; examination commands is somewhat rough: currently only fairly
137 ;; simple entities are found. You can always drag-select or examine
138 ;; a region.
139 ;;
140 ;; When forcing completion of method keywords, the initial
141 ;; query for a method has multiple entries for some methods. Would
142 ;; be too difficult to fix this hardly used case.
143 ;;
144 \f
145 ;;; Code:
150 ;; Kludge to allow `defcustom' for Emacs 19.
153 nil ;; We've got what we needed
154 ;; We have the old or no custom-library, hack around it!
160 "Major mode for editing IDL .pro files"
171 ;;; Variables for indentation behavior ---------------------------------------
174 "Indentation and formatting options for IDLWAVE mode."
178 "*Extra indentation for the main block of code.
179 That is the block between the FUNCTION/PRO statement and the END
180 statement for that program unit."
185 "*Extra indentation applied to block lines.
186 If you change this, you probably also want to change `idlwave-end-offset'."
191 "*Extra indentation applied to block END lines.
192 A value equal to negative `idlwave-block-indent' will make END lines
193 line up with the block BEGIN lines."
198 "*Extra indentation applied to continuation lines.
199 This extra offset applies to the first of a set of continuation lines.
200 The following lines receive the same indentation as the first."
205 "*Maximum additional indentation for special continuation indent.
206 Several special indentations are tried to help line up continuation
207 lines in routine calls or definitions, other statements with
208 parentheses, or assignment statements. This variable specifies a
209 maximum amount by which this special indentation can exceed the
210 standard continuation indentation, otherwise defaulting to a fixed
211 offset. Set to 0 to effectively disable all special continuation
212 indentation, or to a large number (like 100) to enable it in all
213 cases. See also `idlwave-indent-top-open-paren', which can override
214 this variable."
219 "*Non-nil means, indent continuation lines to innermost open
220 parenthesis. This indentation occurs even if otherwise disallowed by
221 `idlwave-max-extra-continuation-indent'. Matching parens and the
222 interleaving args are lined up. Example:
224 x = function_a(function_b(function_c( a, b, [1,2,3, $
225 4,5,6 $
226 ], $
227 c, d $
228 )))
230 When this variable is nil, paren alignment may still occur, based on
231 the value of `max-extra-continuation-indent', which, if zero, would
232 yield:
234 x = function_a(function_b(function_c( a, b, [1,2,3, $
235 4,5,6 $
236 ], $
237 c, d $
238 )))"
243 "*If set non-nil then comment paragraphs are indented under the
244 hanging indent given by `idlwave-hang-indent-regexp' match in the first line
245 of the paragraph."
250 "*Regular expression matching the position of the hanging indent
251 in the first line of a comment paragraph. The size of the indent
252 extends to the end of the match for the regular expression."
257 "*If non-nil then use last match on line for `idlwave-indent-regexp'."
262 "*If non-nil then auto fill will only operate on comment lines."
267 "*If non-nil then auto fill will split strings with the IDL `+' operator.
268 When the line end falls within a string, string concatenation with the
269 '+' operator will be used to distribute a long string over lines.
270 If nil and a string is split then a terminal beep and warning are issued.
272 This variable is ignored when `idlwave-fill-comment-line-only' is
273 non-nil, since in this case code is not auto-filled."
278 "*If non-nil then `idlwave-split-line' will split strings with `+'.
279 When the splitting point of a line falls inside a string, split the string
280 using the `+' string concatenation operator. If nil and a string is
281 split then a terminal beep and warning are issued."
286 "*The indentation of a comment that starts with this regular
287 expression will not be changed. Note that the indentation of a comment
288 at the beginning of a line is never changed."
293 "*A comment anchored at the beginning of line.
294 A comment matching this regular expression will not have its
303 "*A comment that starts with this regular expression on a line by
304 itself is indented as if it is a part of IDL code. As a result if
305 the comment is not preceded by whitespace it is unchanged."
309 ;; Comments not matching any of the above will be indented as a
310 ;; right-margin comment, i.e., to a minimum of `comment-column'.
313 ;;; Routine Info and Completion ---------------------------------------
316 "Routine Info options for IDLWAVE mode."
321 "*Seconds of idle time before routine info is automatically initialized.
322 Initializing the routine info can take long, in particular if a large
323 library catalog is involved. When Emacs is idle for more than the number
324 of seconds specified by this variable, it starts the initialization.
325 The process is split into five steps, in order to keep possible work
326 interruption as short as possible. If one of the steps finishes, and no
327 user input has arrived in the mean time, initialization proceeds immediately
328 to the next step.
329 A good value for this variable is about 1/3 of the time initialization
330 take in you setup. So if you have a fast machine and no problems with a slow network connection, don't hesitate to set this to 2 seconds.
331 A Value of 0 means, don't initialize automatically."
336 "*Non-nil means, scan buffers for IDL programs when updating info.
337 The scanning is done by the command `idlwave-update-routine-info'.
338 The following values are allowed:
340 nil Don't scan any buffers.
341 t Scan all idlwave-mode buffers in the current editing session.
342 current Scan only the current buffer, but no other buffers."
350 "*Non-nil means query the shell for info about compiled routines.
351 Querying the shell is useful to get information about compiled modules,
352 and it is turned on by default. However, when you have a complete library
353 scan, this is not necessary."
359 "*Controls under what circumstances routine info is updated automatically.
360 Possible values:
361 nil Never
362 t All available
363 \(...) A list of circumstances. Allowed members are:
364 find-file Add info for new IDLWAVE buffers.
365 save-buffer Update buffer info when buffer is saved
366 kill-buffer Remove buffer info when buffer gets killed
367 compile-buffer Update shell info after `idlwave-shell-save-and...'"
379 "*Maximum number of source files displayed in the Routine Info window.
380 When an integer, it is the maximum number of source files displayed.
381 t means to show all source files."
386 "Library path for Windows and MacOS. Not needed under Unix.
387 When selecting the directories to scan for IDL library routine info,
388 IDLWAVE can under UNIX query the shell for the exact search path.
389 However, under Windows and MacOS, the IDLWAVE shell does not work. In this
390 case, this variable specifies the path where IDLWAVE can find library files.
391 The shell will only be asked when this variable is nil.
392 The value is a list of directories. A directory preceeded by a `+' will
393 be searched recursively. If you set this variable on a UNIX system, the shell
394 will not be asked.
395 See also `idlwave-system-directory'."
400 "The IDL system directory for Windows and MacOS. Not needed under UNIX.
401 Set this to the value of the `!DIR' system variable in IDL. IDLWAVE uses
402 this to find out which of the library routines belong to the official system
403 library. All files inside the `lib' subdirectory are considered system
404 library files - so don't install private stuff in this directory.
405 On UNIX systems, IDLWAVE queries the shell for the value of `!DIR'.
406 See also `idlwave-library-path'."
411 "*File for routine information of the IDL library.
412 When this points to a file, the file will be loaded when IDLWAVE first
413 accesses routine info (or does completion).
414 When you scan the library with `idlwave-create-libinfo-file', this file
415 will be used to store the result."
420 "Alist of regular expressions matching special library directories.
421 When listing routine source locations, IDLWAVE gives a short hint where
422 the file defining the routine is located. By default it lists `SystemLib'
423 for routines in the system library `!DIR/lib' and `Library' for anything
424 else. This variable can define additional types. The car of each entry
425 is a regular expression matching the file name (they normally will match
426 on the path). The cdr is the string to be used as identifier. Max 10
427 chars are allowed."
433 "Online Help options for IDLWAVE mode."
437 "The directory where idlw-help.txt and idlw-help.el are stored."
442 "*Non-nil means, use a separate frame for Online Help if possible."
448 "The frame parameters for the special Online Help frame.
449 See also `idlwave-help-use-dedicated-frame'.
450 If you do not set the frame width here, the value specified in
451 `idlw-help.el' will be used."
457 "Maximum number of items per pane in popup menus.
458 Currently only used for class selection during completion help."
463 "The function to call for online help if the normal help fails.
464 Online help works only for system routines which are described in the
465 IDL manuals. A function may be specified to access help from other sources.
467 The function must accept four arguments: NAME, TYPE, CLASS, KEYWORD.
468 The Help buffer is current when this function is called, and the help
469 text should be loaded into this buffer. If help is found, the function
470 should return the buffer position which should be used as `window-start'
471 in the help window. Also, the variable `idlwave-help-mode-line-indicator'
472 should be set to a useful string, which will be displayed in the mode line
473 of the help window. If should also set the variable `idlwave-min-frame-width'
474 to a positive integer. IDLWAVE will ensure that the help frame is at
475 least that many columns wide.
476 Failure to find help should be indicated by throwing an error.
478 When this variable is non-nil, IDLWAVE will allow the mouse-3 help click
479 for every routine and keyword, even though the item may not be highlighted
480 in blue (indicating the availability of system documentation).
482 The default value for this function is `idlwave-help-with-source' which
483 loads the routine source file into the help buffer. If you try to write
484 a different function which accesses a special help file or so, it is
485 probably a good idea to still call this function as a fallback."
490 "*Non-nil means, fontify source code displayed as help like normal code."
495 "*Non-nil means, try to find help in routine header when displaying source.
496 Routines which are not documented in the system manual use their source as
497 help text. When this variable is non-nil, we try to find a description of
498 the help item in the first routine doclib header above the routine definition.
499 If the variable is nil, or if we cannot find/parse the header, the routine
500 definition is displayed instead."
507 "Face for highlighting links into IDLWAVE online help."
511 "*Non-nil means, make all possible links in help active.
512 This just activates all words which are also a help topic - some links may
513 be misleading."
519 "Completion options for IDLWAVE mode."
536 "Association list setting the case of completed words.
538 This variable determines the case (UPPER/lower/Capitalized...) of
539 words inserted into the buffer by completion. The preferred case can
540 be specified separately for routine names, keywords, classes and
541 methods.
542 This alist should therefore have entries for `routine' (normal
543 functions and procedures, i.e. non-methods), `keyword', `class', and
544 `method'. Plausible values are
546 upcase upcase whole word, like `BOX_CURSOR'
547 downcase downcase whole word, like `read_ppm'
548 capitalize capitalize each part, like `Widget_Control'
549 preserve preserve case as is, like `IDLgrView'
551 The value can also be any Emacs Lisp function which transforms the
552 case of characters in a string.
554 A value of `preserve' means that the case of the completed word is
555 identical to the way it was written in the definition statement of the
556 routine. This was implemented to allow for mixed-case completion, in
557 particular of object classes and methods.
558 If a completable word is defined in multiple locations, the meaning of
559 `preserve' is not unique since the different definitions might be
560 cased differently. Therefore IDLWAVE always takes the case of the
561 *first* definition it encounters during routine info collection and
562 uses the case derived from it consistently.
564 Note that a lowercase-only string in the buffer will always be completed in
565 lower case (but see the variable `idlwave-completion-force-default-case').
567 After changing this variable, you need to either restart Emacs or press
568 `C-u C-c C-i' to update the internal lists."
575 "*Non-nil means, completion will always honor `idlwave-completion-case'.
576 When nil, only the completion of a mixed case or upper case string
577 will honor the default settings in `idlwave-completion-case', while
578 the completion of lower case strings will be completed entirely in
579 lower case."
584 "*Non-nil means, the empty string is considered downcase for completion.
585 The case of what is already in the buffer determines the case of completions.
586 When this variable is non-nil, the empty string is considered to be downcase.
587 Completing on the empty string then offers downcase versions of the possible
588 completions."
593 "Obsolete variable. See `idlwave-complete-empty-string-as-lower-case' and
597 "*Non-nil means, the case of tokens in buffers dominates over system stuff.
598 To make this possible, we need to re-case everything each time we update
599 the routine info from the buffers. This is slow.
600 The default is to consider the case given in the system and library files
601 first which makes updating much faster."
606 "*Non-nil means, highlight completions for which system help is available.
607 Help can then be accessed with mouse-3.
608 This option is only effective when the online help system is installed."
613 "Non-nil means, treat inheritance with completion, online help etc.
614 When nil, IDLWAVE only knows about the native methods and tags of a class,
615 not about inherited ones."
620 "List of regular expressions for class-driven keyword inheritance.
622 up the class tree. While it cannot be assumed that the presence of an
623 _EXTRA or _REF_EXTRA symbol guarantees such chaining will occur, for
624 certain methods this assumption is almost always true. The methods
625 for which to assume this can be set here."
631 "*Number of classes to show when completing object methods and keywords.
632 When completing methods or keywords for an object with unknown class,
633 the *Completions* buffer will show the legal classes for each completion
634 like this:
636 MyMethod <Class1,Class2,Class3>
638 The value of this variable may be nil to inhibit display, or an integer to
639 indicate the maximum number of classes to display.
641 On XEmacs, a full list of classes will also be placed into a `help-echo'
642 property on the competion items, so that the list of classes for the current
643 item is displayed in the echo area. If the value of this variable is a
644 negative integer, the `help-echo' property will be suppressed."
650 "*Non-nil means, fontify the classes in completions buffer.
651 This makes it easier to distinguish the completion items from the extra
652 class info listed. See `idlwave-completion-show-classes'."
658 "Association list governing specification of object classes for completion.
660 When IDLWAVE tries to complete object-oriented methods, it usually
661 cannot determine the class of a given object from context. In order
662 to provide the user with a correct list of methods or keywords, it
663 needs to determine the appropriate class. IDLWAVE has two ways of
664 doing this (well, three ways if you count the shell... see
665 `idlwave-shell-query-for-class'):
667 1. Combine the items of all available classes which contain this
668 method for the purpose of completion. So when completing a method,
669 all methods of all known classes are available, and when completing
670 a keyword, all keywords allowed for this method in any class are
671 shown. This behavior is very much like normal completion and is
672 therefore the default. It works much better than one might think -
673 only for the INIT, GETPROPERTY and SETPROPERTY the keyword lists
674 become uncomfortably long. See also
675 `idlwave-completion-show-classes'.
677 2. The second possibility is to ask the user on each occasion. To
678 make this less interruptive, IDLWAVE can store the class as a text
679 property on the object operator `->'. For a given object in the
680 source code, class selection will then be needed only once
681 - for example to complete the method. Keywords to the method can
682 then be completed directly, because the class is already known.
683 You will have to turn on the storage of the selected class
684 explicitly with the variable `idlwave-store-inquired-class'.
686 This variable allows you to configure IDLWAVE's method and
687 method-keyword completion behavior. Its value is an alist, which
688 should contain at least two elements: (method-default . VALUE) and
689 \(keyword-default . VALUE), where VALUE is either t or nil. These
690 specify if the class should be found during method and keyword
691 completion, respectively.
693 The alist may have additional entries specifying exceptions from the
694 keyword completion rule for specific methods, like INIT or
695 GETPROPERTY. In order to turn on class specification for the INIT
705 :inline t
710 "*Non-nil means, store class of a method call as text property on `->'.
711 IDLWAVE sometimes has to ask the user for the class associated with a
712 particular object method call. This happens during the commands
713 `idlwave-routine-info' and `idlwave-complete', depending upon the
714 value of the variable `idlwave-query-class'.
716 When you specify a class, this information can be stored as a text
717 property on the `->' arrow in the source code, so that during the same
718 editing session, IDLWAVE will not have to ask again. When this
719 variable is non-nil, IDLWAVE will store and reuse the class information.
721 on the arrow.
723 The default of this variable is nil, since the result of commands then
724 is more predictable. However, if you know what you are doing, it can
725 be nice to turn this on.
727 An arrow which knows the class will be highlighted with
729 displays (with prefix arg: deletes) the class stored on the arrow
730 at point."
735 "*Face to highlight object operator arrows `->' which carry a class property.
736 When IDLWAVE stores a class name as text property on an object arrow
737 \(see variable `idlwave-store-inquired-class', it highlights the arrow
738 with this font in order to remind the user that this arrow is special."
743 "*Non-nil means, resize the Routine-info *Help* window to fit the content."
748 "*Non-nil means, completion automatically adds `=' after completed keywords."
753 "*Non-nil means, completion automatically adds `(' after completed function.
754 nil means, don't add anything.
755 A value of `2' means, also add the closing parenthesis and position cursor
756 between the two."
763 "*Non-nil means, try to restore the window configuration after completion.
764 When completion is not unique, Emacs displays a list of completions.
765 This messes up your window configuration. With this variable set, IDLWAVE
766 restores the old configuration after successful completion."
770 ;;; Variables for abbrev and action behavior -----------------------------
773 "IDLWAVE performs actions when expanding abbreviations or indenting lines.
774 The variables in this group govern this."
778 "*Non-nil means performs actions when indenting.
779 The actions that can be performed are listed in `idlwave-indent-action-table'."
784 "*A single character string used to start abbreviations in abbrev mode.
785 Possible characters to chose from: ~`\%
786 or even '?'. '.' is not a good choice because it can make structure

1780 The main features of this mode are
1782 1. Indentation and Formatting
1783 --------------------------
1784 Like other Emacs programming modes, C-j inserts a newline and indents.
1785 TAB is used for explicit indentation of the current line.
1788 function can also be used in the middle of a line to split the line
1789 at that point. When used inside a long constant string, the string
1790 is split at that point with the `+' concatenation operator.
1792 Comments are indented as follows:
1794 `;;;' Indentation remains unchanged.
1795 `;;' Indent like the surrounding code
1796 `;' Indent to a minimum column.
1798 The indentation of comments starting in column 0 is never changed.
1801 comment. The indentation of the second line of the paragraph
1802 relative to the first will be retained. Use
1804 comments. When the variable `idlwave-fill-comment-line-only' is
1805 nil, code can also be auto-filled and auto-indented (not
1806 recommended).
1808 To convert pre-existing IDL code to your formatting style, mark the
1813 2. Routine Info
1814 ------------
1815 IDLWAVE displays information about the calling sequence and the
1816 accepted keyword parameters of a procedure or function with
1818 source file of a module. These commands know about system
1819 routines, all routines in idlwave-mode buffers and (when the
1820 idlwave-shell is active) about all modules currently compiled under
1822 information, which is also used for completion (see item 4).
1824 3. Online IDL Help
1825 ---------------
1827 for the system variable, keyword, or routine at point. A single key
1828 stroke gets you directly to the right place in the docs. Two additional
1829 files (an ASCII version of the IDL documentation and a topics file) must
1830 be installed for this - check the IDLWAVE webpage for these files.
1832 4. Completion
1833 ----------
1835 class names and keyword parameters. It is context sensitive and
1836 figures out what is expected at point (procedure/function/keyword).
1837 Lower case strings are completed in lower case, other strings in
1838 mixed or upper case.
1840 5. Code Templates and Abbreviations
1841 --------------------------------
1842 Many Abbreviations are predefined to expand to code fragments and templates.
1857 direct keybindings - see the list of keybindings below.
1860 current program unit (pro, function or main). Change log entries
1863 6. Automatic Case Conversion
1864 -------------------------
1865 The case of reserved words and some abbrevs is controlled by
1866 `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
1868 7. Automatic END completion
1869 ------------------------
1870 If the variable `idlwave-expand-generic-end' is non-nil, each END typed
1871 will be converted to the specific version, like ENDIF, ENDFOR, etc.
1873 8. Hooks
1874 -----
1875 Loading idlwave.el runs `idlwave-load-hook'.
1876 Turning on `idlwave-mode' runs `idlwave-mode-hook'.
1878 9. Documentation and Customization
1879 -------------------------------
1880 Info documentation for this package is available. Use
1882 not work). For Postscript, PDF, and HTML versions of the
1883 documentation, check IDLWAVE's homepage at `http://idlwave.org'.
1884 IDLWAVE has customize support - see the group `idlwave'.
