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

99 ;; CUSTOMIZATION:
100 ;; =============
102 ;; IDLWAVE has extensive customize support; to learn about the
103 ;; variables which control the mode's behavior, use `M-x
104 ;; idlwave-customize'.
106 ;; You can set your own preferred values with Customize, or with Lisp
107 ;; code in .emacs. For an example of what to put into .emacs, check
108 ;; the TexInfo documentation or see a complete .emacs available at the
109 ;; website.
111 ;; KNOWN PROBLEMS:
112 ;; ==============
114 ;; IDLWAVE support for the IDL-derived PV-WAVE CL language of Visual
115 ;; Numerics, Inc. is growing less and less complete as the two
116 ;; languages grow increasingly apart. The mode probably shouldn't
117 ;; even have "WAVE" in its title, but it's catchy, and was required
118 ;; to avoid conflict with the CORBA idl.el mode. Caveat WAVEor.
120 ;; Moving the point backwards in conjunction with abbrev expansion
121 ;; does not work as I would like it, but this is a problem with
122 ;; emacs abbrev expansion done by the self-insert-command. It ends
123 ;; up inserting the character that expanded the abbrev after moving
124 ;; point backward, e.g., "\cl" expanded with a space becomes
125 ;; "LONG( )" with point before the close paren. This is solved by
126 ;; using a temporary function in `post-command-hook' - not pretty,
127 ;; but it works.
129 ;; Tabs and spaces are treated equally as whitespace when filling a
130 ;; comment paragraph. To accomplish this, tabs are permanently
131 ;; replaced by spaces in the text surrounding the paragraph, which
132 ;; may be an undesirable side-effect. Replacing tabs with spaces is
133 ;; limited to comments only and occurs only when a comment
134 ;; paragraph is filled via `idlwave-fill-paragraph'.
136 ;; Muti-statement lines (using "&") on block begin and end lines can
137 ;; ruin the formatting. For example, multiple end statements on a
138 ;; line: endif & endif. Using "&" outside of block begin/end lines
139 ;; should be okay.
141 ;; Determining the expression at point for printing and other
142 ;; examination commands is somewhat rough: currently only fairly
143 ;; simple entities are found. You can always drag-select or examine
144 ;; a pre-selected region.
146 ;; When forcing completion of method keywords, the initial
147 ;; query for a method has multiple entries for some methods. Would
148 ;; be too difficult to fix this hardly used case.

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

1779 "Major mode for editing IDL source files (version 6.1_em22).
1781 The main features of this mode are
1783 1. Indentation and Formatting
1784 --------------------------
1785 Like other Emacs programming modes, C-j inserts a newline and indents.
1786 TAB is used for explicit indentation of the current line.
1788 To start a continuation line, use \\[idlwave-split-line]. This
1789 function can also be used in the middle of a line to split the line
1790 at that point. When used inside a long constant string, the string
1791 is split at that point with the `+' concatenation operator.
1793 Comments are indented as follows:
1795 `;;;' Indentation remains unchanged.
1796 `;;' Indent like the surrounding code
1797 `;' Indent to a minimum column.
1799 The indentation of comments starting in column 0 is never changed.
1801 Use \\[idlwave-fill-paragraph] to refill a paragraph inside a
1802 comment. The indentation of the second line of the paragraph
1803 relative to the first will be retained. Use
1804 \\[idlwave-auto-fill-mode] to toggle auto-fill mode for these
1805 comments. When the variable `idlwave-fill-comment-line-only' is
1806 nil, code can also be auto-filled and auto-indented.
1808 To convert pre-existing IDL code to your formatting style, mark the
1809 entire buffer with \\[mark-whole-buffer] and execute
1810 \\[idlwave-expand-region-abbrevs]. Then mark the entire buffer
1811 again followed by \\[indent-region] (`indent-region').
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
1817 \\[idlwave-routine-info]. \\[idlwave-find-module] jumps to the
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
1821 this shell. It also makes use of pre-compiled or custom-scanned
1822 user and library catalogs many popular libraries ship with by
1823 default. Use \\[idlwave-update-routine-info] to update this
1824 information, which is also used for completion (see item 4).
1826 3. Online IDL Help
1827 ---------------
1829 \\[idlwave-context-help] displays the IDL documentation relevant
1830 for the system variable, keyword, or routines at point. A single
1831 key stroke gets you directly to the right place in the docs. See
1832 the manual to configure where and how the HTML help is displayed.
1834 4. Completion
1835 ----------
1836 \\[idlwave-complete] completes the names of procedures, functions
1837 class names, keyword parameters, system variables and tags, class
1838 tags, structure tags, filenames and much more. It is context
1839 sensitive and figures out what is expected at point. Lower case
1840 strings are completed in lower case, other strings in mixed or
1841 upper case.
1843 5. Code Templates and Abbreviations
1844 --------------------------------
1845 Many Abbreviations are predefined to expand to code fragments and templates.
1846 The abbreviations start generally with a `\\`. Some examples:
1848 \\pr PROCEDURE template
1849 \\fu FUNCTION template
1850 \\c CASE statement template
1851 \\sw SWITCH statement template
1852 \\f FOR loop template
1853 \\r REPEAT Loop template
1854 \\w WHILE loop template
1855 \\i IF statement template
1856 \\elif IF-ELSE statement template
1857 \\b BEGIN
1859 For a full list, use \\[idlwave-list-abbrevs]. Some templates also
1860 have direct keybindings - see the list of keybindings below.
1862 \\[idlwave-doc-header] inserts a documentation header at the
1863 beginning of the current program unit (pro, function or main).
1864 Change log entries can be added to the current program unit with
1865 \\[idlwave-doc-modification].
1867 6. Automatic Case Conversion
1868 -------------------------
1869 The case of reserved words and some abbrevs is controlled by
1870 `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
1872 7. Automatic END completion
1873 ------------------------
1874 If the variable `idlwave-expand-generic-end' is non-nil, each END typed
1875 will be converted to the specific version, like ENDIF, ENDFOR, etc.
1877 8. Hooks
1878 -----
1879 Loading idlwave.el runs `idlwave-load-hook'.
1880 Turning on `idlwave-mode' runs `idlwave-mode-hook'.
1882 9. Documentation and Customization
1883 -------------------------------
1884 Info documentation for this package is available. Use
1885 \\[idlwave-info] to display (complain to your sysadmin if that does
1886 not work). For Postscript, PDF, and HTML versions of the
1887 documentation, check IDLWAVE's homepage at URL `http://idlwave.org'.
1888 IDLWAVE has customize support - see the group `idlwave'.
1890 10.Keybindings
1891 -----------
1892 Here is a list of all keybindings of this mode.
1893 If some of the key bindings below show with ??, use \\[describe-key]
1894 followed by the key sequence to see what the key sequence does.

5833 This function is smart and figures out what can be completed

5835 - At the beginning of a statement it completes procedure names.
5836 - In the middle of a statement it completes function names.
5837 - After a `(' or `,' in the argument list of a function or procedure,
5838 it completes a keyword of the relevant function or procedure.
5839 - In the first arg of `OBJ_NEW', it completes a class name.
5841 When several completions are possible, a list will be displayed in
5842 the *Completions* buffer. If this list is too long to fit into the
5843 window, scrolling can be achieved by repeatedly pressing
5844 \\[idlwave-complete].
5846 The function also knows about object methods. When it needs a class
5847 name, the action depends upon `idlwave-query-class', which see. You
5848 can force IDLWAVE to ask you for a class name with a
5849 \\[universal-argument] prefix argument to this command.
5851 See also the variables `idlwave-keyword-completion-adds-equal' and
5852 `idlwave-function-completion-adds-paren'.
5854 The optional ARG can be used to specify the completion type in order
5855 to override IDLWAVE's idea of what should be completed at point.
5856 Possible values are:
5858 0 <=> query for the completion type
5859 1 <=> 'procedure
5860 2 <=> 'procedure-keyword
5861 3 <=> 'function
5862 4 <=> 'function-keyword
5863 5 <=> 'procedure-method
5864 6 <=> 'procedure-method-keyword
5865 7 <=> 'function-method
5866 8 <=> 'function-method-keyword
5867 9 <=> 'class
5869 As a special case, the universal argument C-u forces completion of
5870 function names in places where the default would be a keyword.
5872 Two prefix argument, C-u C-u, prompts for a regexp by which to limit
5873 completion.
5875 For Lisp programmers only:
5876 When we force a keyword, optional argument MODULE can contain the module name.
5877 When we force a method or a method keyword, CLASS can specify the class."
