31 ;; IDLWAVE enables feature-rich development and interaction with IDL,
32 ;; the Interactive Data Language. It provides a compelling,
33 ;; full-featured alternative to the IDLDE development environment
36 ;; In the remotely distant past, based on pascal.el, though bears
37 ;; little resemblance to it now.
39 ;; Incorporates many ideas, such as abbrevs, action routines, and
40 ;; continuation line indenting, from wave.el.

104 ;; IDLWAVE has extensive customize support; to learn about the
105 ;; variables which control the mode's behavior, use `M-x
106 ;; idlwave-customize'.
108 ;; You can set your own preferred values with Customize, or with Lisp
109 ;; code in .emacs. For an example of what to put into .emacs, check
110 ;; the TexInfo documentation or see a complete .emacs available at the
116 ;; IDLWAVE support for the IDL-derived PV-WAVE CL language of Visual
117 ;; Numerics, Inc. is growing less and less complete as the two
118 ;; languages grow increasingly apart. The mode probably shouldn't
119 ;; even have "WAVE" in its title, but it's catchy, and was required
120 ;; to avoid conflict with the CORBA idl.el mode. Caveat WAVEor.
122 ;; Moving the point backwards in conjunction with abbrev expansion
123 ;; does not work as I would like it, but this is a problem with
124 ;; emacs abbrev expansion done by the self-insert-command. It ends
125 ;; up inserting the character that expanded the abbrev after moving
126 ;; point backward, e.g., "\cl" expanded with a space becomes
127 ;; "LONG( )" with point before the close paren. This is solved by
128 ;; using a temporary function in `post-command-hook' - not pretty,
131 ;; Tabs and spaces are treated equally as whitespace when filling a
132 ;; comment paragraph. To accomplish this, tabs are permanently
133 ;; replaced by spaces in the text surrounding the paragraph, which
134 ;; may be an undesirable side-effect. Replacing tabs with spaces is
135 ;; limited to comments only and occurs only when a comment
136 ;; paragraph is filled via `idlwave-fill-paragraph'.
138 ;; Muti-statement lines (using "&") on block begin and end lines can
139 ;; ruin the formatting. For example, multiple end statements on a
140 ;; line: endif & endif. Using "&" outside of block begin/end lines
143 ;; Determining the expression at point for printing and other
144 ;; examination commands is somewhat rough: currently only fairly
145 ;; simple entities are found. You can always drag-select or examine
146 ;; a pre-selected region.
148 ;; When forcing completion of method keywords, the initial
149 ;; query for a method has multiple entries for some methods. Would
150 ;; be too difficult to fix this hardly used case.

636 needs to determine the appropriate class. IDLWAVE has two ways of
637 doing this (well, three ways if you count the shell... see
638 `idlwave-shell-query-for-class'):
640 1. Combine the items of all available classes which contain this
641 method for the purpose of completion. So when completing a method,
642 all methods of all known classes are available, and when completing
643 a keyword, all keywords allowed for this method in any class are
644 shown. This behavior is very much like normal completion and is
645 therefore the default. It works much better than one might think -
646 only for the INIT, GETPROPERTY and SETPROPERTY the keyword lists
647 become uncomfortably long. See also
648 `idlwave-completion-show-classes'.
650 2. The second possibility is to ask the user on each occasion. To
651 make this less interruptive, IDLWAVE can store the class as a text
652 property on the object operator `->'. For a given object in the
653 source code, class selection will then be needed only once
654 - for example to complete the method. Keywords to the method can
655 then be completed directly, because the class is already known.
656 You will have to turn on the storage of the selected class
657 explicitly with the variable `idlwave-store-inquired-class'.
659 This variable allows you to configure IDLWAVE's method and
660 method-keyword completion behavior. Its value is an alist, which
661 should contain at least two elements: (method-default . VALUE) and
662 \(keyword-default . VALUE), where VALUE is either t or nil. These
663 specify if the class should be found during method and keyword
664 completion, respectively.
666 The alist may have additional entries specifying exceptions from the
667 keyword completion rule for specific methods, like INIT or
668 GETPROPERTY. In order to turn on class specification for the INIT
669 method, add an entry (\"INIT\" . t). The method name must be ALL-CAPS."

686 `idlwave-routine-info' and `idlwave-complete', depending upon the
687 value of the variable `idlwave-query-class'.
689 When you specify a class, this information can be stored as a text
690 property on the `->' arrow in the source code, so that during the same
691 editing session, IDLWAVE will not have to ask again. When this
692 variable is non-nil, IDLWAVE will store and reuse the class information.

1783 "Major mode for editing IDL source files (version 6.1_em22).
1785 The main features of this mode are
1787 1. Indentation and Formatting
1788 --------------------------
1789 Like other Emacs programming modes, C-j inserts a newline and indents.
1790 TAB is used for explicit indentation of the current line.
1792 To start a continuation line, use \\[idlwave-split-line]. This
1793 function can also be used in the middle of a line to split the line
1794 at that point. When used inside a long constant string, the string
1795 is split at that point with the `+' concatenation operator.
1797 Comments are indented as follows:
1799 `;;;' Indentation remains unchanged.
1800 `;;' Indent like the surrounding code
1801 `;' Indent to a minimum column.
1803 The indentation of comments starting in column 0 is never changed.
1805 Use \\[idlwave-fill-paragraph] to refill a paragraph inside a
1806 comment. The indentation of the second line of the paragraph
1807 relative to the first will be retained. Use
1808 \\[idlwave-auto-fill-mode] to toggle auto-fill mode for these
1809 comments. When the variable `idlwave-fill-comment-line-only' is
1810 nil, code can also be auto-filled and auto-indented.
1812 To convert pre-existing IDL code to your formatting style, mark the
1813 entire buffer with \\[mark-whole-buffer] and execute
1814 \\[idlwave-expand-region-abbrevs]. Then mark the entire buffer
1815 again followed by \\[indent-region] (`indent-region').
1819 IDLWAVE displays information about the calling sequence and the
1820 accepted keyword parameters of a procedure or function with
1821 \\[idlwave-routine-info]. \\[idlwave-find-module] jumps to the
1822 source file of a module. These commands know about system
1823 routines, all routines in idlwave-mode buffers and (when the
1824 idlwave-shell is active) about all modules currently compiled under
1825 this shell. It also makes use of pre-compiled or custom-scanned
1826 user and library catalogs many popular libraries ship with by
1827 default. Use \\[idlwave-update-routine-info] to update this
1828 information, which is also used for completion (see item 4).
1833 \\[idlwave-context-help] displays the IDL documentation relevant
1834 for the system variable, keyword, or routines at point. A single
1835 key stroke gets you directly to the right place in the docs. See
1836 the manual to configure where and how the HTML help is displayed.
1840 \\[idlwave-complete] completes the names of procedures, functions
1841 class names, keyword parameters, system variables and tags, class
1842 tags, structure tags, filenames and much more. It is context
1843 sensitive and figures out what is expected at point. Lower case
1844 strings are completed in lower case, other strings in mixed or
1847 5. Code Templates and Abbreviations
1848 --------------------------------
1849 Many Abbreviations are predefined to expand to code fragments and templates.
1850 The abbreviations start generally with a `\\`. Some examples
1852 \\pr PROCEDURE template
1853 \\fu FUNCTION template
1854 \\c CASE statement template
1855 \\sw SWITCH statement template
1856 \\f FOR loop template
1857 \\r REPEAT Loop template
1858 \\w WHILE loop template
1859 \\i IF statement template
1860 \\elif IF-ELSE statement template
1863 For a full list, use \\[idlwave-list-abbrevs]. Some templates also
1864 have direct keybindings - see the list of keybindings below.
1866 \\[idlwave-doc-header] inserts a documentation header at the
1867 beginning of the current program unit (pro, function or main).
1868 Change log entries can be added to the current program unit with
1869 \\[idlwave-doc-modification].
1871 6. Automatic Case Conversion
1872 -------------------------
1873 The case of reserved words and some abbrevs is controlled by
1874 `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
1876 7. Automatic END completion
1877 ------------------------
1878 If the variable `idlwave-expand-generic-end' is non-nil, each END typed
1879 will be converted to the specific version, like ENDIF, ENDFOR, etc.
1883 Loading idlwave.el runs `idlwave-load-hook'.
1884 Turning on `idlwave-mode' runs `idlwave-mode-hook'.
1886 9. Documentation and Customization
1887 -------------------------------
1888 Info documentation for this package is available. Use
1889 \\[idlwave-info] to display (complain to your sysadmin if that does
1890 not work). For Postscript, PDF, and HTML versions of the
1891 documentation, check IDLWAVE's homepage at `http://idlwave.org'.
1892 IDLWAVE has customize support - see the group `idlwave'.
1896 Here is a list of all keybindings of this mode.
1897 If some of the key bindings below show with ??, use \\[describe-key]
1898 followed by the key sequence to see what the key sequence does.

4121 ;; string is a hand-crafted way. Hashes are used to map the downcase
4122 ;; version of the strings to the cased versions. Most *-sint-*
4123 ;; variables consist of *two* hashes, a buffer+shell, followed by a
4124 ;; system hash. The former is re-scanned, and the latter takes case
4127 ;; Since these cased versions are really lisp objects, we can use `eq'

4129 ;; need to be "sinterned". We do this as early as possible after
4130 ;; getting these strings from completion or buffer substrings. So
4131 ;; most of the code can simply assume to deal with "sinterned"
4132 ;; strings. The only exception is that the functions which scan whole
4133 ;; buffers for routine information do not intern the grabbed strings.
4134 ;; This is only done afterwards. Therefore in these functions it is
4135 ;; *not* safe to assume the strings can be compared with `eq' and be
4136 ;; fed into the routine assq functions.

5876 This function is smart and figures out what can be completed
5878 - At the beginning of a statement it completes procedure names.
5879 - In the middle of a statement it completes function names.
5880 - after a `(' or `,' in the argument list of a function or procedure,
5881 it completes a keyword of the relevant function or procedure.
5882 - In the first arg of `OBJ_NEW', it completes a class name.
5884 When several completions are possible, a list will be displayed in the
5885 *Completions* buffer. If this list is too long to fit into the
5886 window, scrolling can be achieved by repeatedly pressing
5887 \\[idlwave-complete].
5889 The function also knows about object methods. When it needs a class
5890 name, the action depends upon `idlwave-query-class', which see. You
5891 can force IDLWAVE to ask you for a class name with a
5892 \\[universal-argument] prefix argument to this command.
5894 See also the variables `idlwave-keyword-completion-adds-equal' and
5895 `idlwave-function-completion-adds-paren'.
5897 The optional ARG can be used to specify the completion type in order
5898 to override IDLWAVE's idea of what should be completed at point.
5899 Possible values are:
5901 0 <=> query for the completion type
5903 2 <=> 'procedure-keyword
5905 4 <=> 'function-keyword
5906 5 <=> 'procedure-method
5907 6 <=> 'procedure-method-keyword
5908 7 <=> 'function-method
5909 8 <=> 'function-method-keyword
5912 As a special case, the universal argument C-u forces completion of
5913 function names in places where the default would be a keyword.
5915 Two prefix argument, C-u C-u, prompts for a regexp by which to limit
5918 For Lisp programmers only:
5919 When we force a keyword, optional argument MODULE can contain the module name.
