31 | ;; IDLWAVE enables feature-rich development and interaction with IDL. |
32 | ||
52a244eb S |
33 | ;; In the remotely distant past, based on pascal.el, though bears |
34 | ;; little resemblance to it now. | |
f32b3b91 CD |
35 | ;; |
36 | ;; Incorporates many ideas, such as abbrevs, action routines, and | |
37 | ;; continuation line indenting, from wave.el. | |
38 | ;; wave.el original written by Lubos Pochman, Precision Visuals, Boulder. | |
39 | ;; | |
40 | ;; See the mode description ("C-h m" in idlwave-mode or "C-h f idlwave-mode") | |
41 | ;; for features, key bindings, and info. | |
42 | ;; Also, Info format documentation is available with `M-x idlwave-info' | |

98 | ;; CUSTOMIZATION: | |
99 | ;; ============= | |
100 | ;; | |
52a244eb S |
101 | ;; IDLWAVE has extensive customize support; to learn about the |
102 | ;; variables which control the mode's behavior, use `M-x | |
103 | ;; idlwave-customize'. | |
f32b3b91 CD |
104 | ;; |
105 | ;; You can set your own preferred values with Customize, or with Lisp | |
106 | ;; code in .emacs. For an example of what to put into .emacs, check | |
52a244eb S |
107 | ;; the TexInfo documentation or see a complete .emacs available at the |
108 | ;; website. | |
f32b3b91 CD |
109 | ;; |
110 | ;; KNOWN PROBLEMS: | |
111 | ;; ============== | |
112 | ;; | |
76959b77 S |
113 | ;; IDLWAVE support for the IDL-derived PV-WAVE CL language of Visual |
114 | ;; Numerics, Inc. is growing less and less complete as the two | |
115 | ;; languages grow increasingly apart. The mode probably shouldn't | |
3938cb82 | 116 | ;; even have "WAVE" in its title, but it's catchy, and was required |
52a244eb | 117 | ;; to avoid conflict with the CORBA idl.el mode. Caveat WAVEor. |
76959b77 | 118 | ;; |
f32b3b91 CD |
119 | ;; Moving the point backwards in conjunction with abbrev expansion |
120 | ;; does not work as I would like it, but this is a problem with | |
121 | ;; emacs abbrev expansion done by the self-insert-command. It ends | |
122 | ;; up inserting the character that expanded the abbrev after moving | |
123 | ;; point backward, e.g., "\cl" expanded with a space becomes | |
124 | ;; "LONG( )" with point before the close paren. This is solved by | |
31b58798 | 125 | ;; using a temporary function in `post-command-hook' - not pretty, |
595ab50b | 126 | ;; but it works. |
f32b3b91 CD |
127 | ;; |
128 | ;; Tabs and spaces are treated equally as whitespace when filling a | |
129 | ;; comment paragraph. To accomplish this, tabs are permanently | |
130 | ;; replaced by spaces in the text surrounding the paragraph, which | |
131 | ;; may be an undesirable side-effect. Replacing tabs with spaces is | |
132 | ;; limited to comments only and occurs only when a comment | |
133 | ;; paragraph is filled via `idlwave-fill-paragraph'. | |
134 | ;; | |
52a244eb S |
135 | ;; Muti-statement lines (using "&") on block begin and end lines can |
136 | ;; ruin the formatting. For example, multiple end statements on a | |
137 | ;; line: endif & endif. Using "&" outside of block begin/end lines | |
138 | ;; should be okay. | |
f32b3b91 | 139 | ;; |
76959b77 S |
140 | ;; Determining the expression at point for printing and other |
141 | ;; examination commands is somewhat rough: currently only fairly | |
142 | ;; simple entities are found. You can always drag-select or examine | |
52a244eb | 143 | ;; a pre-selected region. |
f32b3b91 | 144 | ;; |
f32b3b91 CD |
145 | ;; When forcing completion of method keywords, the initial |
146 | ;; query for a method has multiple entries for some methods. Would | |
595ab50b | 147 | ;; be too difficult to fix this hardly used case. |

622 | When IDLWAVE tries to complete object-oriented methods, it usually |

624 | to provide the user with a correct list of methods or keywords, it | |
76959b77 S |
625 | needs to determine the appropriate class. IDLWAVE has two ways of |
626 | doing this (well, three ways if you count the shell... see | |
627 | `idlwave-shell-query-for-class'): | |
628 | ||
629 | 1. Combine the items of all available classes which contain this | |
630 | method for the purpose of completion. So when completing a method, | |
631 | all methods of all known classes are available, and when completing | |
632 | a keyword, all keywords allowed for this method in any class are | |
633 | shown. This behavior is very much like normal completion and is | |
634 | therefore the default. It works much better than one might think - | |
635 | only for the INIT, GETPROPERTY and SETPROPERTY the keyword lists | |
636 | become uncomfortably long. See also | |
5e72c6b2 | 637 | `idlwave-completion-show-classes'. |
f32b3b91 CD |
638 | |
639 | 2. The second possibility is to ask the user on each occasion. To | |
640 | make this less interruptive, IDLWAVE can store the class as a text | |
641 | property on the object operator `->'. For a given object in the | |
642 | source code, class selection will then be needed only once | |
643 | - for example to complete the method. Keywords to the method can | |
644 | then be completed directly, because the class is already known. | |
645 | You will have to turn on the storage of the selected class | |
646 | explicitly with the variable `idlwave-store-inquired-class'. | |
647 | ||
5e72c6b2 S |
648 | This variable allows you to configure IDLWAVE's method and |

facebc7b | 651 | \(keyword-default . VALUE), where VALUE is either t or nil. These |
5e72c6b2 S |
652 | specify if the class should be found during method and keyword |
653 | completion, respectively. | |
f32b3b91 | 654 | |
31b58798 | 655 | The alist may have additional entries specifying exceptions from the |
f32b3b91 CD |
656 | keyword completion rule for specific methods, like INIT or |
657 | GETPROPERTY. In order to turn on class specification for the INIT | |

1774 | 1. Indentation and Formatting | |
1775 | -------------------------- | |
1776 | Like other Emacs programming modes, C-j inserts a newline and indents. | |
1777 | TAB is used for explicit indentation of the current line. | |
1778 | ||
5e72c6b2 S |
1779 | To start a continuation line, use \\[idlwave-split-line]. This |
1780 | function can also be used in the middle of a line to split the line | |
1781 | at that point. When used inside a long constant string, the string | |
1782 | is split at that point with the `+' concatenation operator. | |
f32b3b91 CD |
1783 | |
1784 | Comments are indented as follows: | |
1785 | ||
1786 | `;;;' Indentation remains unchanged. | |
1787 | `;;' Indent like the surrounding code | |
1788 | `;' Indent to a minimum column. | |
1789 | ||
1790 | The indentation of comments starting in column 0 is never changed. | |
1791 | ||
5e72c6b2 S |
1792 | Use \\[idlwave-fill-paragraph] to refill a paragraph inside a |
1793 | comment. The indentation of the second line of the paragraph | |
1794 | relative to the first will be retained. Use | |
1795 | \\[idlwave-auto-fill-mode] to toggle auto-fill mode for these | |
1796 | comments. When the variable `idlwave-fill-comment-line-only' is | |
52a244eb | 1797 | nil, code can also be auto-filled and auto-indented. |
f32b3b91 CD |
1798 | |
1799 | To convert pre-existing IDL code to your formatting style, mark the | |
5e72c6b2 S |
1800 | entire buffer with \\[mark-whole-buffer] and execute |
1801 | \\[idlwave-expand-region-abbrevs]. Then mark the entire buffer | |
1802 | again followed by \\[indent-region] (`indent-region'). | |
f32b3b91 CD |
1803 | |
1804 | 2. Routine Info | |
1805 | ------------ | |
5e72c6b2 S |
1806 | IDLWAVE displays information about the calling sequence and the |
1807 | accepted keyword parameters of a procedure or function with | |
1808 | \\[idlwave-routine-info]. \\[idlwave-find-module] jumps to the | |
1809 | source file of a module. These commands know about system | |
1810 | routines, all routines in idlwave-mode buffers and (when the | |
1811 | idlwave-shell is active) about all modules currently compiled under | |
52a244eb S |
1812 | this shell. It also makes use of pre-compiled or custom-scanned |
1813 | user and library catalogs many popular libraries ship with by | |
1814 | default. Use \\[idlwave-update-routine-info] to update this | |
15e42531 CD |
1815 | information, which is also used for completion (see item 4). |
1816 | ||
1817 | 3. Online IDL Help | |
1818 | --------------- | |
1819 | \\[idlwave-context-help] displays the IDL documentation relevant | |
52a244eb S |
1820 | for the system variable, keyword, or routine at point. A single |
1821 | key stroke gets you directly to the right place in the docs. The | |
1822 | HTML help files package must be installed for this to work -- check | |
1823 | the IDLWAVE webpage for the correct package for your version. See | |
1824 | the manual to configure where and how the HTML help is displayed. | |
f32b3b91 | 1825 | |
15e42531 | 1826 | 4. Completion |
f32b3b91 | 1827 | ---------- |
15e42531 | 1828 | \\[idlwave-complete] completes the names of procedures, functions |
52a244eb S |
1829 | class names, keyword parameters, system variables and tags, class |
1830 | tags, structure tags, filenames and much more. It is context | |
1831 | sensitive and figures out what is expected at point. Lower case | |
1832 | strings are completed in lower case, other strings in mixed or | |
1833 | upper case. | |
f32b3b91 | 1834 | |
15e42531 | 1835 | 5. Code Templates and Abbreviations |
f32b3b91 CD |
1836 | -------------------------------- |
1837 | Many Abbreviations are predefined to expand to code fragments and templates. | |
1838 | The abbreviations start generally with a `\\`. Some examples | |
1839 | ||
1840 | \\pr PROCEDURE template | |
1841 | \\fu FUNCTION template | |
1842 | \\c CASE statement template | |
05a1abfc | 1843 | \\sw SWITCH statement template |
f32b3b91 CD |
1844 | \\f FOR loop template |
1845 | \\r REPEAT Loop template | |
1846 | \\w WHILE loop template | |
1847 | \\i IF statement template | |
1848 | \\elif IF-ELSE statement template | |
1849 | \\b BEGIN | |
31b58798 | 1850 | |
52a244eb S |
1851 | For a full list, use \\[idlwave-list-abbrevs]. Some templates also |
1852 | have direct keybindings - see the list of keybindings below. | |
775591f7 | 1853 | |
52a244eb S |
1854 | \\[idlwave-doc-header] inserts a documentation header at the |
1855 | beginning of the current program unit (pro, function or main). | |
1856 | Change log entries can be added to the current program unit with | |
1857 | \\[idlwave-doc-modification]. | |
f32b3b91 | 1858 | |
15e42531 | 1859 | 6. Automatic Case Conversion |
f32b3b91 CD |
1860 | ------------------------- |
1861 | The case of reserved words and some abbrevs is controlled by | |
1862 | `idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'. | |
1863 | ||
15e42531 | 1864 | 7. Automatic END completion |
f32b3b91 CD |
1865 | ------------------------ |
1866 | If the variable `idlwave-expand-generic-end' is non-nil, each END typed | |
1867 | will be converted to the specific version, like ENDIF, ENDFOR, etc. | |
1868 | ||
15e42531 | 1869 | 8. Hooks |
f32b3b91 CD |
1870 | ----- |
1871 | Loading idlwave.el runs `idlwave-load-hook'. | |
1872 | Turning on `idlwave-mode' runs `idlwave-mode-hook'. | |
1873 | ||
15e42531 | 1874 | 9. Documentation and Customization |
f32b3b91 | 1875 | ------------------------------- |
5e72c6b2 S |
1876 | Info documentation for this package is available. Use |
1877 | \\[idlwave-info] to display (complain to your sysadmin if that does | |
1878 | not work). For Postscript, PDF, and HTML versions of the | |
1879 | documentation, check IDLWAVE's homepage at `http://idlwave.org'. | |
f32b3b91 CD |
1880 | IDLWAVE has customize support - see the group `idlwave'. |
1881 | ||

f32b3b91 CD |
1883 | ----------- |
1884 | Here is a list of all keybindings of this mode. | |
1885 | If some of the key bindings below show with ??, use \\[describe-key] | |
1886 | followed by the key sequence to see what the key sequence does. | |
