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'
45 ;; New versions of IDLWAVE, documentation, and more information
46 ;; available from:

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.

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

678 variable is non-nil, IDLWAVE will store and reuse the class information.
679 The class stored can be checked and removed with `\\[idlwave-routine-info]'

1772 "Major mode for editing IDL source files (version 6.1_em22).
1774 The main features of this mode are
1776 1. Indentation and Formatting
1777 --------------------------
1778 Like other Emacs programming modes, C-j inserts a newline and indents.
1779 TAB is used for explicit indentation of the current line.
1781 To start a continuation line, use \\[idlwave-split-line]. This
1782 function can also be used in the middle of a line to split the line
1783 at that point. When used inside a long constant string, the string
1784 is split at that point with the `+' concatenation operator.
1786 Comments are indented as follows:
1788 `;;;' Indentation remains unchanged.
1789 `;;' Indent like the surrounding code
1790 `;' Indent to a minimum column.
1792 The indentation of comments starting in column 0 is never changed.
1794 Use \\[idlwave-fill-paragraph] to refill a paragraph inside a
1795 comment. The indentation of the second line of the paragraph
1796 relative to the first will be retained. Use
1797 \\[idlwave-auto-fill-mode] to toggle auto-fill mode for these
1798 comments. When the variable `idlwave-fill-comment-line-only' is
1799 nil, code can also be auto-filled and auto-indented.
1801 To convert pre-existing IDL code to your formatting style, mark the
1802 entire buffer with \\[mark-whole-buffer] and execute
1803 \\[idlwave-expand-region-abbrevs]. Then mark the entire buffer
1804 again followed by \\[indent-region] (`indent-region').
1806 2. Routine Info
1807 ------------
1808 IDLWAVE displays information about the calling sequence and the
1809 accepted keyword parameters of a procedure or function with
1810 \\[idlwave-routine-info]. \\[idlwave-find-module] jumps to the
1811 source file of a module. These commands know about system
1812 routines, all routines in idlwave-mode buffers and (when the
1813 idlwave-shell is active) about all modules currently compiled under
1814 this shell. It also makes use of pre-compiled or custom-scanned
1815 user and library catalogs many popular libraries ship with by
1816 default. Use \\[idlwave-update-routine-info] to update this
1817 information, which is also used for completion (see item 4).
1819 3. Online IDL Help
1820 ---------------
1822 \\[idlwave-context-help] displays the IDL documentation relevant
1823 for the system variable, keyword, or routines at point. A single
1824 key stroke gets you directly to the right place in the docs. See
1825 the manual to configure where and how the HTML help is displayed.
1827 4. Completion
1828 ----------
1829 \\[idlwave-complete] completes the names of procedures, functions
1830 class names, keyword parameters, system variables and tags, class
1831 tags, structure tags, filenames and much more. It is context
1832 sensitive and figures out what is expected at point. Lower case
1833 strings are completed in lower case, other strings in mixed or
1834 upper case.
1836 5. Code Templates and Abbreviations
1837 --------------------------------
1838 Many Abbreviations are predefined to expand to code fragments and templates.
1839 The abbreviations start generally with a `\\`. Some examples:
1841 \\pr PROCEDURE template
1842 \\fu FUNCTION template
1843 \\c CASE statement template
1844 \\sw SWITCH statement template
1845 \\f FOR loop template
1846 \\r REPEAT Loop template
1847 \\w WHILE loop template
1848 \\i IF statement template
1849 \\elif IF-ELSE statement template
1850 \\b BEGIN
1852 For a full list, use \\[idlwave-list-abbrevs]. Some templates also
1853 have direct keybindings - see the list of keybindings below.
1855 \\[idlwave-doc-header] inserts a documentation header at the
1856 beginning of the current program unit (pro, function or main).
1857 Change log entries can be added to the current program unit with
1858 \\[idlwave-doc-modification].
1860 6. Automatic Case Conversion
1861 -------------------------
1862 The case of reserved words and some abbrevs is controlled by
1863 `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
1865 7. Automatic END completion
1866 ------------------------
1867 If the variable `idlwave-expand-generic-end' is non-nil, each END typed
1868 will be converted to the specific version, like ENDIF, ENDFOR, etc.
1870 8. Hooks
1871 -----
1872 Loading idlwave.el runs `idlwave-load-hook'.
1873 Turning on `idlwave-mode' runs `idlwave-mode-hook'.
1875 9. Documentation and Customization
1876 -------------------------------
1877 Info documentation for this package is available. Use
1878 \\[idlwave-info] to display (complain to your sysadmin if that does
1879 not work). For Postscript, PDF, and HTML versions of the
1880 documentation, check IDLWAVE's homepage at URL `http://idlwave.org'.
1881 IDLWAVE has customize support - see the group `idlwave'.
1883 10.Keybindings
1884 -----------
1885 Here is a list of all keybindings of this mode.
1886 If some of the key bindings below show with ??, use \\[describe-key]
1887 followed by the key sequence to see what the key sequence does.

5822 This function is smart and figures out what can be completed

5824 - At the beginning of a statement it completes procedure names.
5825 - In the middle of a statement it completes function names.
5826 - After a `(' or `,' in the argument list of a function or procedure,
5827 it completes a keyword of the relevant function or procedure.
5828 - In the first arg of `OBJ_NEW', it completes a class name.
5830 When several completions are possible, a list will be displayed in
5831 the *Completions* buffer. If this list is too long to fit into the
5832 window, scrolling can be achieved by repeatedly pressing
5833 \\[idlwave-complete].
5835 The function also knows about object methods. When it needs a class
5836 name, the action depends upon `idlwave-query-class', which see. You
5837 can force IDLWAVE to ask you for a class name with a
5838 \\[universal-argument] prefix argument to this command.
5840 See also the variables `idlwave-keyword-completion-adds-equal' and
5841 `idlwave-function-completion-adds-paren'.
5843 The optional ARG can be used to specify the completion type in order
5844 to override IDLWAVE's idea of what should be completed at point.
5845 Possible values are:
5847 0 <=> query for the completion type
5848 1 <=> 'procedure
5849 2 <=> 'procedure-keyword
5850 3 <=> 'function
5851 4 <=> 'function-keyword
5852 5 <=> 'procedure-method
5853 6 <=> 'procedure-method-keyword
5854 7 <=> 'function-method
5855 8 <=> 'function-method-keyword
5856 9 <=> 'class
5858 As a special case, the universal argument C-u forces completion of
5859 function names in places where the default would be a keyword.
5861 Two prefix argument, C-u C-u, prompts for a regexp by which to limit
5862 completion.
5864 For Lisp programmers only:
5865 When we force a keyword, optional argument MODULE can contain the module name.
