30 ;;; Commentary:
32 ;; IDLWAVE enables feature-rich development and interaction with IDL,
33 ;; the Interactive Data Language. It provides a compelling,
34 ;; full-featured alternative to the IDLDE development environment
35 ;; bundled with IDL.
37 ;; In the remotely distant past, based on pascal.el, though bears
38 ;; little resemblance to it now.
40 ;; Incorporates many ideas, such as abbrevs, action routines, and
41 ;; continuation line indenting, from wave.el.
42 ;; wave.el original written by Lubos Pochman, Precision Visuals, Boulder.
44 ;; See the mode description ("C-h m" in idlwave-mode or "C-h f idlwave-mode")
45 ;; for features, key bindings, and info.
46 ;; Also, Info format documentation is available with `M-x idlwave-info'
48 ;; New versions of IDLWAVE, documentation, and more information

102 ;; CUSTOMIZATION:
103 ;; =============
105 ;; IDLWAVE has extensive customize support; to learn about the
106 ;; variables which control the mode's behavior, use `M-x
107 ;; idlwave-customize'.
109 ;; You can set your own preferred values with Customize, or with Lisp
110 ;; code in .emacs. For an example of what to put into .emacs, check
111 ;; the TexInfo documentation or see a complete .emacs available at the
112 ;; website.
114 ;; KNOWN PROBLEMS:
115 ;; ==============
117 ;; IDLWAVE support for the IDL-derived PV-WAVE CL language of Visual
118 ;; Numerics, Inc. is growing less and less complete as the two
119 ;; languages grow increasingly apart. The mode probably shouldn't
120 ;; even have "WAVE" in its title, but it's catchy, and was required
121 ;; to avoid conflict with the CORBA idl.el mode. Caveat WAVEor.
123 ;; Moving the point backwards in conjunction with abbrev expansion
124 ;; does not work as I would like it, but this is a problem with
125 ;; emacs abbrev expansion done by the self-insert-command. It ends
126 ;; up inserting the character that expanded the abbrev after moving
127 ;; point backward, e.g., "\cl" expanded with a space becomes
128 ;; "LONG( )" with point before the close paren. This is solved by
129 ;; using a temporary function in `post-command-hook' - not pretty,
130 ;; but it works.
132 ;; Tabs and spaces are treated equally as whitespace when filling a
133 ;; comment paragraph. To accomplish this, tabs are permanently
134 ;; replaced by spaces in the text surrounding the paragraph, which
135 ;; may be an undesirable side-effect. Replacing tabs with spaces is
136 ;; limited to comments only and occurs only when a comment
137 ;; paragraph is filled via `idlwave-fill-paragraph'.
139 ;; Muti-statement lines (using "&") on block begin and end lines can
140 ;; ruin the formatting. For example, multiple end statements on a
141 ;; line: endif & endif. Using "&" outside of block begin/end lines
142 ;; should be okay.
144 ;; Determining the expression at point for printing and other
145 ;; examination commands is somewhat rough: currently only fairly
146 ;; simple entities are found. You can always drag-select or examine
147 ;; a pre-selected region.
149 ;; When forcing completion of method keywords, the initial
150 ;; query for a method has multiple entries for some methods. Would
151 ;; be too difficult to fix this hardly used case.

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

1784 "Major mode for editing IDL source files (version 6.1_em22).
1786 The main features of this mode are
1788 1. Indentation and Formatting
1789 --------------------------
1790 Like other Emacs programming modes, C-j inserts a newline and indents.
1791 TAB is used for explicit indentation of the current line.
1793 To start a continuation line, use \\[idlwave-split-line]. This
1794 function can also be used in the middle of a line to split the line
1795 at that point. When used inside a long constant string, the string
1796 is split at that point with the `+' concatenation operator.
1798 Comments are indented as follows:
1800 `;;;' Indentation remains unchanged.
1801 `;;' Indent like the surrounding code
1802 `;' Indent to a minimum column.
1804 The indentation of comments starting in column 0 is never changed.
1806 Use \\[idlwave-fill-paragraph] to refill a paragraph inside a
1807 comment. The indentation of the second line of the paragraph
1808 relative to the first will be retained. Use
1809 \\[idlwave-auto-fill-mode] to toggle auto-fill mode for these
1810 comments. When the variable `idlwave-fill-comment-line-only' is
1811 nil, code can also be auto-filled and auto-indented.
1813 To convert pre-existing IDL code to your formatting style, mark the
1814 entire buffer with \\[mark-whole-buffer] and execute
1815 \\[idlwave-expand-region-abbrevs]. Then mark the entire buffer
1816 again followed by \\[indent-region] (`indent-region').
1818 2. Routine Info
1819 ------------
1820 IDLWAVE displays information about the calling sequence and the
1821 accepted keyword parameters of a procedure or function with
1822 \\[idlwave-routine-info]. \\[idlwave-find-module] jumps to the
1823 source file of a module. These commands know about system
1824 routines, all routines in idlwave-mode buffers and (when the
1825 idlwave-shell is active) about all modules currently compiled under
1826 this shell. It also makes use of pre-compiled or custom-scanned
1827 user and library catalogs many popular libraries ship with by
1828 default. Use \\[idlwave-update-routine-info] to update this
1829 information, which is also used for completion (see item 4).
1831 3. Online IDL Help
1832 ---------------
1834 \\[idlwave-context-help] displays the IDL documentation relevant
1835 for the system variable, keyword, or routines at point. A single
1836 key stroke gets you directly to the right place in the docs. See
1837 the manual to configure where and how the HTML help is displayed.
1839 4. Completion
1840 ----------
1841 \\[idlwave-complete] completes the names of procedures, functions
1842 class names, keyword parameters, system variables and tags, class
1843 tags, structure tags, filenames and much more. It is context
1844 sensitive and figures out what is expected at point. Lower case
1845 strings are completed in lower case, other strings in mixed or
1846 upper case.
1848 5. Code Templates and Abbreviations
1849 --------------------------------
1850 Many Abbreviations are predefined to expand to code fragments and templates.
1851 The abbreviations start generally with a `\\`. Some examples
1853 \\pr PROCEDURE template
1854 \\fu FUNCTION template
1855 \\c CASE statement template
1856 \\sw SWITCH statement template
1857 \\f FOR loop template
1858 \\r REPEAT Loop template
1859 \\w WHILE loop template
1860 \\i IF statement template
1861 \\elif IF-ELSE statement template
1862 \\b BEGIN
1864 For a full list, use \\[idlwave-list-abbrevs]. Some templates also
1865 have direct keybindings - see the list of keybindings below.
1867 \\[idlwave-doc-header] inserts a documentation header at the
1868 beginning of the current program unit (pro, function or main).
1869 Change log entries can be added to the current program unit with
1870 \\[idlwave-doc-modification].
1872 6. Automatic Case Conversion
1873 -------------------------
1874 The case of reserved words and some abbrevs is controlled by
1875 `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
1877 7. Automatic END completion
1878 ------------------------
1879 If the variable `idlwave-expand-generic-end' is non-nil, each END typed
1880 will be converted to the specific version, like ENDIF, ENDFOR, etc.
1882 8. Hooks
1883 -----
1884 Loading idlwave.el runs `idlwave-load-hook'.
1885 Turning on `idlwave-mode' runs `idlwave-mode-hook'.
1887 9. Documentation and Customization
1888 -------------------------------
1889 Info documentation for this package is available. Use
1890 \\[idlwave-info] to display (complain to your sysadmin if that does
1891 not work). For Postscript, PDF, and HTML versions of the
1892 documentation, check IDLWAVE's homepage at `http://idlwave.org'.
1893 IDLWAVE has customize support - see the group `idlwave'.
1895 10.Keybindings
1896 -----------
1897 Here is a list of all keybindings of this mode.
1898 If some of the key bindings below show with ??, use \\[describe-key]
1899 followed by the key sequence to see what the key sequence does.

4120 ;; For the completion and routine info function, we want to normalize
4121 ;; the case of procedure names etc. We do this by "interning" these
4122 ;; string is a hand-crafted way. Hashes are used to map the downcase
4123 ;; version of the strings to the cased versions. Most *-sint-*
4124 ;; variables consist of *two* hashes, a buffer+shell, followed by a
4125 ;; system hash. The former is re-scanned, and the latter takes case
4126 ;; precedence.
4128 ;; Since these cased versions are really lisp objects, we can use `eq'
4129 ;; to search, which is a large performance boost. All new strings
4130 ;; need to be "sinterned". We do this as early as possible after
4131 ;; getting these strings from completion or buffer substrings. So
4132 ;; most of the code can simply assume to deal with "sinterned"
4133 ;; strings. The only exception is that the functions which scan whole
4134 ;; buffers for routine information do not intern the grabbed strings.
4135 ;; This is only done afterwards. Therefore in these functions it is
4136 ;; *not* safe to assume the strings can be compared with `eq' and be

5886 - In the middle of a statement it completes function names.
5887 - after a `(' or `,' in the argument list of a function or procedure,
5888 it completes a keyword of the relevant function or procedure.
5889 - In the first arg of `OBJ_NEW', it completes a class name.
5891 When several completions are possible, a list will be displayed in the
5892 *Completions* buffer. If this list is too long to fit into the
5893 window, scrolling can be achieved by repeatedly pressing
5894 \\[idlwave-complete].
5896 The function also knows about object methods. When it needs a class
5897 name, the action depends upon `idlwave-query-class', which see. You
5898 can force IDLWAVE to ask you for a class name with a
5899 \\[universal-argument] prefix argument to this command.
5901 See also the variables `idlwave-keyword-completion-adds-equal' and
5902 `idlwave-function-completion-adds-paren'.
5904 The optional ARG can be used to specify the completion type in order
5905 to override IDLWAVE's idea of what should be completed at point.
5906 Possible values are:
5908 0 <=> query for the completion type
5909 1 <=> 'procedure
5910 2 <=> 'procedure-keyword
5911 3 <=> 'function
5912 4 <=> 'function-keyword
5913 5 <=> 'procedure-method
5914 6 <=> 'procedure-method-keyword
5915 7 <=> 'function-method
5916 8 <=> 'function-method-keyword
5917 9 <=> 'class
5919 As a special case, the universal argument C-u forces completion of
5920 function names in places where the default would be a keyword.
5922 Two prefix argument, C-u C-u, prompts for a regexp by which to limit
5923 completion.
5925 For Lisp programmers only:
5926 When we force a keyword, optional argument MODULE can contain the module name.
5927 When we force a method or a method keyword, CLASS can specify the class."
