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.

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

1780 "Major mode for editing IDL source files (version 6.1_em22).
1782 The main features of this mode are
1784 1. Indentation and Formatting
1785 --------------------------
1786 Like other Emacs programming modes, C-j inserts a newline and indents.
1787 TAB is used for explicit indentation of the current line.
1789 To start a continuation line, use \\[idlwave-split-line]. This
1790 function can also be used in the middle of a line to split the line
1791 at that point. When used inside a long constant string, the string
1792 is split at that point with the `+' concatenation operator.
1794 Comments are indented as follows:
1796 `;;;' Indentation remains unchanged.
1797 `;;' Indent like the surrounding code
1798 `;' Indent to a minimum column.
1800 The indentation of comments starting in column 0 is never changed.
1802 Use \\[idlwave-fill-paragraph] to refill a paragraph inside a
1803 comment. The indentation of the second line of the paragraph
1804 relative to the first will be retained. Use
1805 \\[idlwave-auto-fill-mode] to toggle auto-fill mode for these
1806 comments. When the variable `idlwave-fill-comment-line-only' is
1807 nil, code can also be auto-filled and auto-indented.
1809 To convert pre-existing IDL code to your formatting style, mark the
1810 entire buffer with \\[mark-whole-buffer] and execute
1811 \\[idlwave-expand-region-abbrevs]. Then mark the entire buffer
1812 again followed by \\[indent-region] (`indent-region').
1814 2. Routine Info
1815 ------------
1816 IDLWAVE displays information about the calling sequence and the
1817 accepted keyword parameters of a procedure or function with
1818 \\[idlwave-routine-info]. \\[idlwave-find-module] jumps to the
1819 source file of a module. These commands know about system
1820 routines, all routines in idlwave-mode buffers and (when the
1821 idlwave-shell is active) about all modules currently compiled under
1822 this shell. It also makes use of pre-compiled or custom-scanned
1823 user and library catalogs many popular libraries ship with by
1824 default. Use \\[idlwave-update-routine-info] to update this
1825 information, which is also used for completion (see item 4).
1827 3. Online IDL Help
1828 ---------------
1830 \\[idlwave-context-help] displays the IDL documentation relevant
1831 for the system variable, keyword, or routines at point. A single
1832 key stroke gets you directly to the right place in the docs. See
1833 the manual to configure where and how the HTML help is displayed.
1835 4. Completion
1836 ----------
1837 \\[idlwave-complete] completes the names of procedures, functions
1838 class names, keyword parameters, system variables and tags, class
1839 tags, structure tags, filenames and much more. It is context
1840 sensitive and figures out what is expected at point. Lower case
1841 strings are completed in lower case, other strings in mixed or
1842 upper case.
1844 5. Code Templates and Abbreviations
1845 --------------------------------
1846 Many Abbreviations are predefined to expand to code fragments and templates.
1847 The abbreviations start generally with a `\\`. Some examples
1849 \\pr PROCEDURE template
1850 \\fu FUNCTION template
1851 \\c CASE statement template
1852 \\sw SWITCH statement template
1853 \\f FOR loop template
1854 \\r REPEAT Loop template
1855 \\w WHILE loop template
1856 \\i IF statement template
1857 \\elif IF-ELSE statement template
1858 \\b BEGIN
1860 For a full list, use \\[idlwave-list-abbrevs]. Some templates also
1861 have direct keybindings - see the list of keybindings below.
1863 \\[idlwave-doc-header] inserts a documentation header at the
1864 beginning of the current program unit (pro, function or main).
1865 Change log entries can be added to the current program unit with
1866 \\[idlwave-doc-modification].
1868 6. Automatic Case Conversion
1869 -------------------------
1870 The case of reserved words and some abbrevs is controlled by
1871 `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
1873 7. Automatic END completion
1874 ------------------------
1875 If the variable `idlwave-expand-generic-end' is non-nil, each END typed
1876 will be converted to the specific version, like ENDIF, ENDFOR, etc.
1878 8. Hooks
1879 -----
1880 Loading idlwave.el runs `idlwave-load-hook'.
1881 Turning on `idlwave-mode' runs `idlwave-mode-hook'.
1883 9. Documentation and Customization
1884 -------------------------------
1885 Info documentation for this package is available. Use
1886 \\[idlwave-info] to display (complain to your sysadmin if that does
1887 not work). For Postscript, PDF, and HTML versions of the
1888 documentation, check IDLWAVE's homepage at `http://idlwave.org'.
1889 IDLWAVE has customize support - see the group `idlwave'.
1891 10.Keybindings
1892 -----------
1893 Here is a list of all keybindings of this mode.
1894 If some of the key bindings below show with ??, use \\[describe-key]
1895 followed by the key sequence to see what the key sequence does.

4114 ;; For the completion and routine info function, we want to normalize
4115 ;; the case of procedure names etc. We do this by "interning" these
4116 ;; string is a hand-crafted way. Hashes are used to map the downcase
4117 ;; version of the strings to the cased versions. Most *-sint-*
4118 ;; variables consist of *two* hashes, a buffer+shell, followed by a
4119 ;; system hash. The former is re-scanned, and the latter takes case
4120 ;; precedence.
4122 ;; Since these cased versions are really lisp objects, we can use `eq'
4123 ;; to search, which is a large performance boost. All new strings
4124 ;; need to be "sinterned". We do this as early as possible after
4125 ;; getting these strings from completion or buffer substrings. So
4126 ;; most of the code can simply assume to deal with "sinterned"
4127 ;; strings. The only exception is that the functions which scan whole
4128 ;; buffers for routine information do not intern the grabbed strings.
4129 ;; This is only done afterwards. Therefore in these functions it is
4130 ;; *not* safe to assume the strings can be compared with `eq' and be
4131 ;; fed into the routine assq functions.

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
5902 1 <=> 'procedure
5903 2 <=> 'procedure-keyword
5904 3 <=> 'function
5905 4 <=> 'function-keyword
5906 5 <=> 'procedure-method
5907 6 <=> 'procedure-method-keyword
5908 7 <=> 'function-method
5909 8 <=> 'function-method-keyword
5910 9 <=> 'class
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
5916 completion.
5918 For Lisp programmers only:
5919 When we force a keyword, optional argument MODULE can contain the module name.
5920 When we force a method or a method keyword, CLASS can specify the class."
