35 | ;;; To use this mode put the following into your .emacs file: |
36 | |
37 | ;; (autoload 'perl-mode "cperl-mode" "alternate mode for editing Perl programs" t) |
38 | |
39 | ;;; You can either fine-tune the bells and whistles of this mode or |
40 | ;;; bulk enable them by putting |
41 | |
42 | ;; (setq cperl-hairy t) |
43 | |
44 | ;;; in your .emacs file. (Emacs rulers do not consider it politically |
45 | ;;; correct to make whistles enabled by default.) |
46 | |
47 | ;;; Additional useful commands to put into your .emacs file: |
48 | |
49 | ;; (setq auto-mode-alist |
50 | ;; (append '(("\\.[pP][Llm]$" . perl-mode)) auto-mode-alist )) |
51 | ;; (setq interpreter-mode-alist (append interpreter-mode-alist |
52 | ;; '(("miniperl" . perl-mode)))) |
53 | |
54 | ;;; The mode information (on C-h m) provides customization help. |
55 | ;;; If you use font-lock feature of this mode, it is advisable to use |
56 | ;;; eather lazy-lock-mode or fast-lock-mode (available on ELisp |
57 | ;;; archive in files lazy-lock.el and fast-lock.el). I prefer lazy-lock. |
58 | |
59 | ;;; Faces used now: three faces for first-class and second-class keywords |
60 | ;;; and control flow words, one for each: comments, string, labels, |
61 | ;;; functions definitions and packages, arrays, hashes, and variable |
62 | ;;; definitions. If you do not see all these faces, your font-lock does |
63 | ;;; not define them, so you need to define them manually. Maybe you have |
64 | ;;; an obsolete font-lock from 19.28 or earlier. Upgrade. |
65 | |
66 | ;;; If you have grayscale monitor, and do not have the variable |
67 | ;;; font-lock-display-type bound to 'grayscale, insert |
68 | |
69 | ;;; (setq font-lock-display-type 'grayscale) |
70 | |
71 | ;;; to your .emacs file. |
72 | |

73 | ;;;; This mode supports font-lock, imenu and mode-compile. In the |
4633a7c4 |
74 | ;;;; hairy version font-lock is on, but you should activate imenu |
29043b61 |
75 | ;;;; yourself (note that mode-compile is not standard yet). Well, you |
4633a7c4 |
76 | ;;;; can use imenu from keyboard anyway (M-x imenu), but it is better |
77 | ;;;; to bind it like that: |
78 | |
79 | ;; (define-key global-map [M-S-down-mouse-3] 'imenu) |
80 | |
81 | ;;; In fact the version of font-lock that this version supports can be |
82 | ;;; much newer than the version you actually have. This means that a |
83 | ;;; lot of faces can be set up, but are not visible on your screen |
84 | ;;; since the coloring rules for this faces are not defined. |
85 | |

86 | ;;; Updates: ======================================== |
87 | |
88 | ;;; Made less hairy by default: parentheses not electric, |
89 | ;;; linefeed not magic. Bug with abbrev-mode corrected. |
90 | |
91 | ;;;; After 1.4: |
92 | ;;; Better indentation: |
93 | ;;; subs inside braces should work now, |
94 | ;;; Toplevel braces obey customization. |
95 | ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment |
96 | ;;; moves cursor to a correct place. |
97 | ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-( |
98 | ;;; (50 secs on DB::DB (sub of 430 lines), 486/66) |
99 | ;;; Minor documentation fixes. |
100 | ;;; Imenu understands packages as prefixes (including nested). |
101 | ;;; Hairy options can be switched off one-by-one by setting to null. |
102 | ;;; Names of functions and variables changed to conform to `cperl-' style. |
103 | |
104 | ;;;; After 1.5: |
105 | ;;; Some bugs with indentation of labels (and embedded subs) corrected. |
106 | ;;; `cperl-indent-region' done (slow :-()). |
107 | ;;; `cperl-fill-paragraph' done. |
108 | ;;; Better package support for `imenu'. |
109 | ;;; Progress indicator for indentation (with `imenu' loaded). |
110 | ;;; `Cperl-set' was busted, now setting the individual hairy option |
111 | ;;; should be better. |
112 | |
113 | ;;;; After 1.6: |
114 | ;;; `cperl-set-style' done. |
115 | ;;; `cperl-check-syntax' done. |
116 | ;;; Menu done. |
117 | ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'. |
118 | ;;; Bugs with `cperl-auto-newline' corrected. |
119 | ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation |
120 | ;;; like $hash{. |
121 | |
122 | ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de): |
123 | ;;; - use `next-command-event', if `next-command-events' does not exist |
124 | ;;; - use `find-face' as def. of `is-face' |
125 | ;;; - corrected def. of `x-color-defined-p' |
126 | ;;; - added const defs for font-lock-comment-face, |
127 | ;;; font-lock-keyword-face and font-lock-function-name-face |
128 | ;;; - added def. of font-lock-variable-name-face |
129 | ;;; - added (require 'easymenu) inside an `eval-when-compile' |
130 | ;;; - replaced 4-argument `substitute-key-definition' with ordinary |
131 | ;;; `define-key's |
132 | ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'. |
133 | ;;; Todo (at least): |
134 | ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz) |
135 | ;;; for portable code? |
136 | ;;; - should `cperl-mode' do a |
137 | ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu)) |
138 | ;;; or should this be left to the user's `cperl-mode-hook'? |
139 | |
140 | ;;; Some bugs introduced by the above fix corrected (IZ ;-). |
141 | ;;; Some bugs under XEmacs introduced by the correction corrected. |
142 | |
143 | ;;; Some more can remain since there are two many different variants. |
144 | ;;; Please feedback! |
145 | |
146 | ;;; We do not support fontification of arrays and hashes under |
147 | ;;; obsolete font-lock any more. Upgrade. |
148 | |
149 | ;;;; after 1.8 Minor bug with parentheses. |
150 | ;;;; after 1.9 Improvements from Joe Marzot. |
151 | ;;;; after 1.10 |
152 | ;;; Does not need easymenu to compile under XEmacs. |
153 | ;;; `vc-insert-headers' should work better. |
154 | ;;; Should work with 19.29 and 19.12. |
155 | ;;; Small improvements to fontification. |
156 | ;;; Expansion of keywords does not depend on C-? being backspace. |
157 | |
158 | ;;; after 1.10+ |
159 | ;;; 19.29 and 19.12 supported. |
160 | ;;; `cperl-font-lock-enhanced' deprecated. Use font-lock-extra.el. |
161 | ;;; Support for font-lock-extra.el. |
162 | |
163 | ;;;; After 1.11: |
164 | ;;; Tools submenu. |
165 | ;;; Support for perl5-info. |
166 | ;;; `imenu-go-find-at-position' in Tools requires imenu-go.el (see hints above) |
167 | ;;; Imenu entries do not work with stock imenu.el. Patch sent to maintainers. |
168 | ;;; Fontifies `require a if b;', __DATA__. |
169 | ;;; Arglist for auto-fill-mode was incorrect. |
170 | |
171 | ;;;; After 1.12: |
172 | ;;; `cperl-lineup-step' and `cperl-lineup' added: lineup constructions |
173 | ;;; vertically. |
174 | ;;; `cperl-do-auto-fill' updated for 19.29 style. |
175 | ;;; `cperl-info-on-command' now has a default. |
176 | ;;; Workaround for broken C-h on XEmacs. |
177 | ;;; VC strings escaped. |
178 | ;;; C-h f now may prompt for function name instead of going on, |
179 | ;;; controlled by `cperl-info-on-command-no-prompt'. |
180 | |
181 | ;;;; After 1.13: |
182 | ;;; Msb buffer list includes perl files |
183 | ;;; Indent-for-comment uses indent-to |
184 | ;;; Can write tag files using etags. |
185 | |
186 | ;;;; After 1.14: |
187 | ;;; Recognizes (tries to ;-) {...} which are not blocks during indentation. |
188 | ;;; `cperl-close-paren-offset' affects ?\] too (and ?\} if not block) |
c07a80fd |
189 | ;;; Bug with auto-filling comments started with "##" corrected. |

210 | ;;; `cperl-pod-here-fontify', `cperl-pod-face'. Does not use this info |
211 | ;;; for indentation so far. |
212 | ;;; Fontification updated to 19.30 style. |
213 | ;;; The change 19.29->30 did not add all the required functionality, |
214 | ;;; but broke "font-lock-extra.el". Get "choose-color.el" from |

216 | |
217 | ;;;; After 1.16: |

219 | ;;; recognized as a start of a block. |
220 | ;;; Two different font-lock-levels provided. |
221 | ;;; `cperl-pod-head-face' introduced. Used for highlighting. |
222 | ;;; `imenu' marks pods, +Packages moved to the head. |
223 | |
224 | ;;;; After 1.17: |
225 | ;;; Scan for pods highlights here-docs too. |
226 | ;;; Note that the tag of here-doc may be rehighlighted later by lazy-lock. |
227 | ;;; Only one here-doc-tag per line is supported, and one in comment |
228 | ;;; or a string may break fontification. |
229 | ;;; POD headers were supposed to fill one line only. |
230 | |
231 | ;;;; After 1.18: |
232 | ;;; `font-lock-keywords' were set in 19.30 style _always_. Current scheme |
233 | ;;; may break under XEmacs. |
234 | ;;; `cperl-calculate-indent' dis suppose that `parse-start' was defined. |
235 | ;;; `fontified' tag is added to fontified text as well as `lazy-lock' (for |
236 | ;;; compatibility with older lazy-lock.el) (older one overfontifies |
237 | ;;; something nevertheless :-(). |
238 | ;;; Will not indent something inside pod and here-documents. |
239 | ;;; Fontifies the package name after import/no/bootstrap. |
240 | ;;; Added new entry to menu with meta-info about the mode. |
4633a7c4 |
241 | |
29043b61 |
242 | ;;;; After 1.19: |
243 | ;;; Prefontification works much better with 19.29. Should be checked |
244 | ;;; with 19.30 as well. |
245 | ;;; Some misprints in docs corrected. |
246 | ;;; Now $a{-text} and -text => "blah" are fontified as strings too. |
247 | ;;; Now the pod search is much stricter, so it can help you to find |
248 | ;;; pod sections which are broken because of whitespace before =blah |
249 | ;;; - just observe the fontification. |
250 | |
9ea28adb |
251 | ;;;; After 1.20 |
252 | ;;; Anonymous subs are indented with respect to the level of |
253 | ;;; indentation of `sub' now. |
254 | ;;; {} is recognized as hash after `bless' and `return'. |
255 | ;;; Anonymous subs are split by `cperl-linefeed' as well. |
256 | ;;; Electric parens embrace a region if present. |
257 | ;;; To make `cperl-auto-newline' useful, |
258 | ;;; `cperl-auto-newline-after-colon' is introduced. |
259 | ;;; `cperl-electric-parens' is now t or nul. The old meaning is moved to |
260 | ;;; `cperl-electric-parens-string'. |
261 | ;;; `cperl-toggle-auto-newline' introduced, put on C-c C-a. |
262 | ;;; `cperl-toggle-abbrev' introduced, put on C-c C-k. |
263 | ;;; `cperl-toggle-electric' introduced, put on C-c C-e. |
264 | ;;; Beginning-of-defun-regexp was not anchored. |
265 | |
266 | ;;;; After 1.21 |
267 | ;;; Auto-newline grants `cperl-extra-newline-before-brace' if "{" is typed |
268 | ;;; after ")". |
269 | ;;; {} is recognized as expression after `tr' and friends. |
270 | |
271 | ;;;; After 1.22 |
272 | ;;; Entry Hierarchy added to imenu. Very primitive so far. |
273 | ;;; One needs newer `imenu-go'.el. A patch to `imenu' is needed as well. |
274 | ;;; Writes its own TAGS files. |
275 | ;;; Class viewer based on TAGS files. Does not trace @ISA so far. |
276 | ;;; 19.31: Problems with scan for PODs corrected. |
277 | ;;; First POD header correctly fontified. |
278 | ;;; I needed (setq imenu-use-keymap-menu t) to get good imenu in 19.31. |
279 | ;;; Apparently it makes a lot of hierarchy code obsolete... |
280 | |
281 | ;;;; After 1.23 |
282 | ;;; Tags filler now scans *.xs as well. |
283 | ;;; The info from *.xs scan is used by the hierarchy viewer. |
284 | ;;; Hierarchy viewer documented. |
285 | ;;; Bug in 19.31 imenu documented. |
286 | |
499d5216 |
287 | ;;;; After 1.24 |
288 | ;;; New location for info-files mentioned, |
289 | ;;; Electric-; should work better. |
290 | ;;; Minor bugs with POD marking. |
291 | |
292 | ;;;; After 1.25 |
293 | ;;; `cperl-info-page' introduced. |
294 | ;;; To make `uncomment-region' working, `comment-region' would |
295 | ;;; not insert extra space. |
296 | ;;; Here documents delimiters better recognized |
297 | ;;; (empty one, and non-alphanums in quotes handled). May be wrong with 1<<14? |
298 | ;;; `cperl-db' added, used in menu. |
299 | ;;; imenu scan removes text-properties, for better debugging |
300 | ;;; - but the bug is in 19.31 imenu. |
301 | ;;; formats highlighted by font-lock and prescan, embedded comments |
302 | ;;; are not treated. |
303 | ;;; POD/friends scan merged in one pass. |
304 | ;;; Syntax class is not used for analyzing the code, only char-syntax |
305 | ;;; may be cecked against _ or'ed with w. |
306 | ;;; Syntax class of `:' changed to be _. |

478 | It may be corrected on the level of C code, please look in the |
479 | `non-problems' section if you want to volunteer. |
c07a80fd |
480 | |
481 | CPerl mode tries to corrects some Emacs misunderstandings, however, |
482 | for effeciency reasons the degree of correction is different for |
483 | different operations. The partially corrected problems are: POD |
484 | sections, here-documents, regexps. The operations are: highlighting, |
485 | indentation, electric keywords, electric braces. |
486 | |
487 | This may be confusing, since the regexp s#//#/#\; may be highlighted |
488 | as a comment, but it will recognized as a regexp by the indentation |
489 | code. Or the opposite case, when a pod section is highlighted, but |
490 | breaks the indentation of the following code. |
491 | |
492 | The main trick (to make $ a \"backslash\") makes constructions like |
493 | ${aaa} look like unbalanced braces. The only trick I can think out is |
494 | to insert it as $ {aaa} (legal in perl5, not in perl4). |
495 | |
496 | Similar problems arise in regexps, when /(\\s|$)/ should be rewritten |
497 | as /($|\\s)/. Note that such a transpositinon is not always possible |
498 | :-(. " ) |
499 | |
500 | (defvar cperl-non-problems 'please-ignore-this-line |
501 | "As you know from `problems' section, Perl syntax too hard for CPerl. |
502 | |
503 | Most the time, if you write your own code, you may find an equivalent |
504 | \(and almost as readable) expression. |
505 | |
506 | Try to help it: add comments with embedded quotes to fix CPerl |
507 | misunderstandings about the end of quotation: |
508 | |
509 | $a='500$'; # '; |
510 | |
511 | You won't need it too often. The reason: $ \"quotes\" the following |
512 | character (this saves a life a lot of times in CPerl), thus due to |
513 | Emacs parsing rules it does not consider tick after the dollar as a |
514 | closing one, but as a usual character. |
515 | |
516 | Now the indentation code is pretty wise. The only drawback is that it |
517 | relies on Emacs parsing to find matching parentheses. And Emacs |
518 | *cannot* match parentheses in Perl 100% correctly. So |
519 | 1 if s#//#/#; |
520 | will not break indentation, but |
521 | 1 if ( s#//#/# ); |
522 | will. |
523 | |
524 | If you still get wrong indentation in situation that you think the |
525 | code should be able to parse, try: |
526 | |
527 | a) Check what Emacs thinks about balance of your parentheses. |
528 | b) Supply the code to me (IZ). |
529 | |
530 | Pods are treated _very_ rudimentally. Here-documents are not treated |
531 | at all (except highlighting and inhibiting indentation). (This may |
532 | change some time. RMS approved making syntax lookup recognize text |
533 | attributes, but volonteers are needed to change Emacs C code.) |
534 | |
535 | To speed up coloring the following compromises exist: |
536 | a) sub in $mypackage::sub may be highlighted. |
537 | b) -z in [a-z] may be highlighted. |
538 | c) if your regexp contains a keyword (like \"s\"), it may be highlighted. |

541 | Imenu in 19.31 is broken. Set `imenu-use-keymap-menu' to t, and remove |

794 | "Major mode for editing Perl code. |
795 | Expression and list commands understand all C brackets. |
796 | Tab indents for Perl code. |
797 | Paragraphs are separated by blank lines only. |
798 | Delete converts tabs to spaces as it moves back. |
799 | |
800 | Various characters in Perl almost always come in pairs: {}, (), [], |
801 | sometimes <>. When the user types the first, she gets the second as |
802 | well, with optional special formatting done on {}. (Disabled by |
803 | default.) You can always quote (with \\[quoted-insert]) the left |
804 | \"paren\" to avoid the expansion. The processing of < is special, |
805 | since most the time you mean \"less\". Cperl mode tries to guess |
806 | whether you want to type pair <>, and inserts is if it |
9ea28adb |
807 | appropriate. You can set `cperl-electric-parens-string' to the string that |
4633a7c4 |
808 | contains the parenths from the above list you want to be electrical. |
9ea28adb |
809 | Electricity of parenths is controlled by `cperl-electric-parens'. |
810 | You may also set `cperl-electric-parens-mark' to have electric parens |
811 | look for active mark and \"embrace\" a region if possible.' |
4633a7c4 |
812 | |
813 | CPerl mode provides expansion of the Perl control constructs: |
814 | if, else, elsif, unless, while, until, for, and foreach. |
815 | =========(Disabled by default, see `cperl-electric-keywords'.) |
816 | The user types the keyword immediately followed by a space, which causes |
817 | the construct to be expanded, and the user is positioned where she is most |
818 | likely to want to be. |
819 | eg. when the user types a space following \"if\" the following appears in |
820 | the buffer: |
821 | if () { or if () |
822 | } { |
823 | } |
824 | and the cursor is between the parentheses. The user can then type some |
825 | boolean expression within the parens. Having done that, typing |
826 | \\[cperl-linefeed] places you, appropriately indented on a new line |
827 | between the braces. If CPerl decides that you want to insert |
828 | \"English\" style construct like |
829 | bite if angry; |
830 | it will not do any expansion. See also help on variable |
831 | `cperl-extra-newline-before-brace'. |
832 | |
833 | \\[cperl-linefeed] is a convinience replacement for typing carriage |
834 | return. It places you in the next line with proper indentation, or if |
835 | you type it inside the inline block of control construct, like |
836 | foreach (@lines) {print; print} |
837 | and you are on a boundary of a statement inside braces, it will |
838 | transform the construct into a multiline and will place you into an |
839 | apporpriately indented blank line. If you need a usual |
840 | `newline-and-indent' behaviour, it is on \\[newline-and-indent], |
841 | see documentation on `cperl-electric-linefeed'. |
842 | |
843 | \\{cperl-mode-map} |

845 | Setting the variable `cperl-font-lock' to t switches on |

9ea28adb |
847 | electric space between $ and {, `cperl-electric-parens-string' is the |
848 | string that contains parentheses that should be electric in CPerl (see |
849 | also `cperl-electric-parens-mark' and `cperl-electric-parens'), |
850 | setting `cperl-electric-keywords' enables electric expansion of |
851 | control structures in CPerl. `cperl-electric-linefeed' governs which |
852 | one of two linefeed behavior is preferable. You can enable all these |
853 | options simultaneously (recommended mode of use) by setting |
854 | `cperl-hairy' to t. In this case you can switch separate options off |
855 | by setting them to `null'. Note that one may undo the extra whitespace |
856 | inserted by semis and braces in `auto-newline'-mode by consequent |
857 | \\[cperl-electric-backspace]. |

858 | |
859 | If your site has perl5 documentation in info format, you can use commands |
860 | \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it. |
861 | These keys run commands `cperl-info-on-current-command' and |
862 | `cperl-info-on-command', which one is which is controlled by variable |
863 | `cperl-info-on-command-no-prompt' (in turn affected by `cperl-hairy'). |

c07a80fd |
865 | Variables `cperl-pod-here-scan', `cperl-pod-here-fontify', |
866 | `cperl-pod-face', `cperl-pod-head-face' control processing of pod and |
867 | here-docs sections. In a future version results of scan may be used |
868 | for indentation too, currently they are used for highlighting only. |
869 | |
4633a7c4 |
870 | Variables controlling indentation style: |
871 | `cperl-tab-always-indent' |
872 | Non-nil means TAB in CPerl mode should always reindent the current line, |
873 | regardless of where in the line point is when the TAB command is used. |
874 | `cperl-auto-newline' |
875 | Non-nil means automatically newline before and after braces, |
9ea28adb |
876 | and after colons and semicolons, inserted in Perl code. The following |
877 | \\[cperl-electric-backspace] will remove the inserted whitespace. |
878 | Insertion after colons requires both this variable and |
879 | `cperl-auto-newline-after-colon' set. |
880 | `cperl-auto-newline-after-colon' |
881 | Non-nil means automatically newline even after colons. |
882 | Subject to `cperl-auto-newline' setting. |
4633a7c4 |
883 | `cperl-indent-level' |
884 | Indentation of Perl statements within surrounding block. |
885 | The surrounding block's indentation is the indentation |
886 | of the line on which the open-brace appears. |
887 | `cperl-continued-statement-offset' |
888 | Extra indentation given to a substatement, such as the |
889 | then-clause of an if, or body of a while, or just a statement continuation. |
890 | `cperl-continued-brace-offset' |
891 | Extra indentation given to a brace that starts a substatement. |
892 | This is in addition to `cperl-continued-statement-offset'. |
893 | `cperl-brace-offset' |
894 | Extra indentation for line if it starts with an open brace. |
895 | `cperl-brace-imaginary-offset' |
896 | An open brace following other text is treated as if it the line started |
897 | this far to the right of the actual line indentation. |
898 | `cperl-label-offset' |
899 | Extra indentation for line that is a label. |
900 | `cperl-min-label-indent' |
901 | Minimal indentation for line that is a label. |
902 | |
903 | Settings for K&R and BSD indentation styles are |
904 | `cperl-indent-level' 5 8 |
905 | `cperl-continued-statement-offset' 5 8 |
906 | `cperl-brace-offset' -5 -8 |
907 | `cperl-label-offset' -5 -8 |
908 | |
909 | If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'. |
910 | |
