32 | ;;; To use this mode put the following into your .emacs file: |
33 | |
34 | ;; (autoload 'perl-mode "cperl-mode" "alternate mode for editing Perl programs" t) |
35 | |
36 | ;;; You can either fine-tune the bells and whistles of this mode or |
37 | ;;; bulk enable them by putting |
38 | |
39 | ;; (setq cperl-hairy t) |
40 | |
41 | ;;; in your .emacs file. (Emacs rulers do not consider it politically |
42 | ;;; correct to make whistles enabled by default.) |
43 | |
44 | ;;; Additional useful commands to put into your .emacs file: |
45 | |
46 | ;; (setq auto-mode-alist |
47 | ;; (append '(("\\.[pP][Llm]$" . perl-mode)) auto-mode-alist )) |
48 | ;; (setq interpreter-mode-alist (append interpreter-mode-alist |
49 | ;; '(("miniperl" . perl-mode)))) |
50 | |
51 | ;;; The mode information (on C-h m) provides customization help. |
52 | ;;; If you use font-lock feature of this mode, it is advisable to use |
53 | ;;; eather lazy-lock-mode or fast-lock-mode (available on ELisp |
54 | ;;; archive in files lazy-lock.el and fast-lock.el). I prefer lazy-lock. |
55 | |
56 | ;;; Faces used now: three faces for first-class and second-class keywords |
57 | ;;; and control flow words, one for each: comments, string, labels, |
58 | ;;; functions definitions and packages, arrays, hashes, and variable |
59 | ;;; definitions. If you do not see all these faces, your font-lock does |
60 | ;;; not define them, so you need to define them manually. Maybe you have |
61 | ;;; an obsolete font-lock from 19.28 or earlier. Upgrade. |
62 | |
63 | ;;; If you have grayscale monitor, and do not have the variable |
64 | ;;; font-lock-display-type bound to 'grayscale, insert |
65 | |
66 | ;;; (setq font-lock-display-type 'grayscale) |
67 | |
68 | ;;; to your .emacs file. |
69 | |
70 | ;;;; This mode supports font-lock, imenu and compile-mode. In the |
71 | ;;;; hairy version font-lock is on, but you should activate imenu |
72 | ;;;; yourself (note that compile-mode is not standard yet). Well, you |
73 | ;;;; can use imenu from keyboard anyway (M-x imenu), but it is better |
74 | ;;;; to bind it like that: |
75 | |
76 | ;; (define-key global-map [M-S-down-mouse-3] 'imenu) |
77 | |
78 | ;;; In fact the version of font-lock that this version supports can be |
79 | ;;; much newer than the version you actually have. This means that a |
80 | ;;; lot of faces can be set up, but are not visible on your screen |
81 | ;;; since the coloring rules for this faces are not defined. |
82 | |

83 | ;;; Updates: ======================================== |
84 | |
85 | ;;; Made less hairy by default: parentheses not electric, |
86 | ;;; linefeed not magic. Bug with abbrev-mode corrected. |
87 | |
88 | ;;;; After 1.4: |
89 | ;;; Better indentation: |
90 | ;;; subs inside braces should work now, |
91 | ;;; Toplevel braces obey customization. |
92 | ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment |
93 | ;;; moves cursor to a correct place. |
94 | ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-( |
95 | ;;; (50 secs on DB::DB (sub of 430 lines), 486/66) |
96 | ;;; Minor documentation fixes. |
97 | ;;; Imenu understands packages as prefixes (including nested). |
98 | ;;; Hairy options can be switched off one-by-one by setting to null. |
99 | ;;; Names of functions and variables changed to conform to `cperl-' style. |
100 | |
101 | ;;;; After 1.5: |
102 | ;;; Some bugs with indentation of labels (and embedded subs) corrected. |
103 | ;;; `cperl-indent-region' done (slow :-()). |
104 | ;;; `cperl-fill-paragraph' done. |
105 | ;;; Better package support for `imenu'. |
106 | ;;; Progress indicator for indentation (with `imenu' loaded). |
107 | ;;; `Cperl-set' was busted, now setting the individual hairy option |
108 | ;;; should be better. |
109 | |
110 | ;;;; After 1.6: |
111 | ;;; `cperl-set-style' done. |
112 | ;;; `cperl-check-syntax' done. |
113 | ;;; Menu done. |
114 | ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'. |
115 | ;;; Bugs with `cperl-auto-newline' corrected. |
116 | ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation |
117 | ;;; like $hash{. |
118 | |
119 | ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de): |
120 | ;;; - use `next-command-event', if `next-command-events' does not exist |
121 | ;;; - use `find-face' as def. of `is-face' |
122 | ;;; - corrected def. of `x-color-defined-p' |
123 | ;;; - added const defs for font-lock-comment-face, |
124 | ;;; font-lock-keyword-face and font-lock-function-name-face |
125 | ;;; - added def. of font-lock-variable-name-face |
126 | ;;; - added (require 'easymenu) inside an `eval-when-compile' |
127 | ;;; - replaced 4-argument `substitute-key-definition' with ordinary |
128 | ;;; `define-key's |
129 | ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'. |
130 | ;;; Todo (at least): |
131 | ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz) |
132 | ;;; for portable code? |
133 | ;;; - should `cperl-mode' do a |
134 | ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu)) |
135 | ;;; or should this be left to the user's `cperl-mode-hook'? |
136 | |
137 | ;;; Some bugs introduced by the above fix corrected (IZ ;-). |
138 | ;;; Some bugs under XEmacs introduced by the correction corrected. |
139 | |
140 | ;;; Some more can remain since there are two many different variants. |
141 | ;;; Please feedback! |
142 | |
143 | ;;; We do not support fontification of arrays and hashes under |
144 | ;;; obsolete font-lock any more. Upgrade. |
145 | |
146 | ;;;; after 1.8 Minor bug with parentheses. |
147 | ;;;; after 1.9 Improvements from Joe Marzot. |
148 | ;;;; after 1.10 |
149 | ;;; Does not need easymenu to compile under XEmacs. |
150 | ;;; `vc-insert-headers' should work better. |
151 | ;;; Should work with 19.29 and 19.12. |
152 | ;;; Small improvements to fontification. |
153 | ;;; Expansion of keywords does not depend on C-? being backspace. |
154 | |
155 | ;;; after 1.10+ |
156 | ;;; 19.29 and 19.12 supported. |
157 | ;;; `cperl-font-lock-enhanced' deprecated. Use font-lock-extra.el. |
158 | ;;; Support for font-lock-extra.el. |
159 | |
160 | ;;;; After 1.11: |
161 | ;;; Tools submenu. |
162 | ;;; Support for perl5-info. |
163 | ;;; `imenu-go-find-at-position' in Tools requires imenu-go.el (see hints above) |
164 | ;;; Imenu entries do not work with stock imenu.el. Patch sent to maintainers. |
165 | ;;; Fontifies `require a if b;', __DATA__. |
166 | ;;; Arglist for auto-fill-mode was incorrect. |
167 | |
168 | ;;;; After 1.12: |
169 | ;;; `cperl-lineup-step' and `cperl-lineup' added: lineup constructions |
170 | ;;; vertically. |
171 | ;;; `cperl-do-auto-fill' updated for 19.29 style. |
172 | ;;; `cperl-info-on-command' now has a default. |
173 | ;;; Workaround for broken C-h on XEmacs. |
174 | ;;; VC strings escaped. |
175 | ;;; C-h f now may prompt for function name instead of going on, |
176 | ;;; controlled by `cperl-info-on-command-no-prompt'. |
177 | |
178 | ;;;; After 1.13: |
179 | ;;; Msb buffer list includes perl files |
180 | ;;; Indent-for-comment uses indent-to |
181 | ;;; Can write tag files using etags. |
182 | |
183 | ;;;; After 1.14: |
184 | ;;; Recognizes (tries to ;-) {...} which are not blocks during indentation. |
185 | ;;; `cperl-close-paren-offset' affects ?\] too (and ?\} if not block) |

367 | |
368 | It may be corrected on the level of C ocde, please look in the |
369 | `non-problems' section if you want to volonteer. |
370 | |
371 | CPerl mode tries to corrects some Emacs misunderstandings, however, |
372 | for effeciency reasons the degree of correction is different for |
373 | different operations. The partially corrected problems are: POD |
374 | sections, here-documents, regexps. The operations are: highlighting, |
375 | indentation, electric keywords, electric braces. |
376 | |
377 | This may be confusing, since the regexp s#//#/#\; may be highlighted |
378 | as a comment, but it will recognized as a regexp by the indentation |
379 | code. Or the opposite case, when a pod section is highlighted, but |
380 | breaks the indentation of the following code. |
381 | |
382 | The main trick (to make $ a \"backslash\") makes constructions like |
383 | ${aaa} look like unbalanced braces. The only trick I can think out is |
384 | to insert it as $ {aaa} (legal in perl5, not in perl4). |
385 | |
386 | Similar problems arise in regexps, when /(\\s|$)/ should be rewritten |
387 | as /($|\\s)/. Note that such a transpositinon is not always possible |
388 | :-(. " ) |

391 | "As you know from `problems' section, Perl syntax too hard for CPerl. |
392 | |
393 | Most the time, if you write your own code, you may find an equivalent |
394 | \(and almost as readable) expression. |
395 | |
396 | Try to help it: add comments with embedded quotes to fix CPerl |
397 | misunderstandings about the end of quotation: |
398 | |
399 | $a='500$'; # '; |
400 | |
401 | You won't need it too often. The reason: $ \"quotes\" the following |
402 | character (this saves a life a lot of times in CPerl), thus due to |
403 | Emacs parsing rules it does not consider tick after the dollar as a |
404 | closing one, but as a usual character. |
405 | |
406 | Now the indentation code is pretty wise. The only drawback is that it |
407 | relies on Emacs parsing to find matching parentheses. And Emacs |
408 | *cannot* match parentheses in Perl 100% correctly. So |
409 | 1 if s#//#/#; |

412 | will. |
413 | |
414 | If you still get wrong indentation in situation that you think the |
415 | code should be able to parse, try: |
416 | |
417 | a) Check what Emacs thinks about balance of your parentheses. |
418 | b) Supply the code to me (IZ). |
419 | |
420 | Pods are treated _very_ rudimentally. Here-documents are not treated |
421 | at all (except highlighting and inhibiting indentation). (This may |
422 | change some time. RMS approved making syntax lookup recognize text |
423 | attributes, but volonteers are needed to change Emacs C code.) |
424 | |
425 | To speed up coloring the following compromises exist: |
426 | a) sub in $mypackage::sub may be highlighted. |
427 | b) -z in [a-z] may be highlighted. |
428 | c) if your regexp contains a keyword (like \"s\"), it may be highlighted. |

643 | "Major mode for editing Perl code. |
644 | Expression and list commands understand all C brackets. |
645 | Tab indents for Perl code. |
646 | Paragraphs are separated by blank lines only. |
647 | Delete converts tabs to spaces as it moves back. |
648 | |
649 | Various characters in Perl almost always come in pairs: {}, (), [], |
650 | sometimes <>. When the user types the first, she gets the second as |
651 | well, with optional special formatting done on {}. (Disabled by |
652 | default.) You can always quote (with \\[quoted-insert]) the left |
653 | \"paren\" to avoid the expansion. The processing of < is special, |
654 | since most the time you mean \"less\". Cperl mode tries to guess |
655 | whether you want to type pair <>, and inserts is if it |
656 | appropriate. You can set `cperl-electric-parens' to the string that |
657 | contains the parenths from the above list you want to be electrical. |
658 | |
659 | CPerl mode provides expansion of the Perl control constructs: |
660 | if, else, elsif, unless, while, until, for, and foreach. |
661 | =========(Disabled by default, see `cperl-electric-keywords'.) |
662 | The user types the keyword immediately followed by a space, which causes |
663 | the construct to be expanded, and the user is positioned where she is most |
664 | likely to want to be. |
665 | eg. when the user types a space following \"if\" the following appears in |
666 | the buffer: |
667 | if () { or if () |
668 | } { |
669 | } |
670 | and the cursor is between the parentheses. The user can then type some |
671 | boolean expression within the parens. Having done that, typing |
672 | \\[cperl-linefeed] places you, appropriately indented on a new line |
673 | between the braces. If CPerl decides that you want to insert |
674 | \"English\" style construct like |
675 | bite if angry; |
676 | it will not do any expansion. See also help on variable |
677 | `cperl-extra-newline-before-brace'. |
678 | |
679 | \\[cperl-linefeed] is a convinience replacement for typing carriage |
680 | return. It places you in the next line with proper indentation, or if |
681 | you type it inside the inline block of control construct, like |
682 | foreach (@lines) {print; print} |
683 | and you are on a boundary of a statement inside braces, it will |
684 | transform the construct into a multiline and will place you into an |
685 | apporpriately indented blank line. If you need a usual |
686 | `newline-and-indent' behaviour, it is on \\[newline-and-indent], |
687 | see documentation on `cperl-electric-linefeed'. |

693 | electric space between $ and {, `cperl-electric-parens' is the string |
694 | that contains parentheses that should be electric in CPerl, setting |
695 | `cperl-electric-keywords' enables electric expansion of control |
696 | structures in CPerl. `cperl-electric-linefeed' governs which one of |
697 | two linefeed behavior is preferable. You can enable all these options |
698 | simultaneously (recommended mode of use) by setting `cperl-hairy' to |
699 | t. In this case you can switch separate options off by setting them |
700 | to `null'. |

705 | `cperl-info-on-command', which one is which is controlled by variable |

713 | Variables controlling indentation style: |
714 | `cperl-tab-always-indent' |
715 | Non-nil means TAB in CPerl mode should always reindent the current line, |
716 | regardless of where in the line point is when the TAB command is used. |
717 | `cperl-auto-newline' |
718 | Non-nil means automatically newline before and after braces, |
719 | and after colons and semicolons, inserted in Perl code. |
720 | `cperl-indent-level' |
721 | Indentation of Perl statements within surrounding block. |
722 | The surrounding block's indentation is the indentation |
723 | of the line on which the open-brace appears. |
724 | `cperl-continued-statement-offset' |
725 | Extra indentation given to a substatement, such as the |
726 | then-clause of an if, or body of a while, or just a statement continuation. |
727 | `cperl-continued-brace-offset' |
728 | Extra indentation given to a brace that starts a substatement. |
729 | This is in addition to `cperl-continued-statement-offset'. |
730 | `cperl-brace-offset' |
731 | Extra indentation for line if it starts with an open brace. |
732 | `cperl-brace-imaginary-offset' |
733 | An open brace following other text is treated as if it the line started |
734 | this far to the right of the actual line indentation. |
735 | `cperl-label-offset' |
736 | Extra indentation for line that is a label. |
737 | `cperl-min-label-indent' |
738 | Minimal indentation for line that is a label. |
739 | |
740 | Settings for K&R and BSD indentation styles are |
741 | `cperl-indent-level' 5 8 |
742 | `cperl-continued-statement-offset' 5 8 |
743 | `cperl-brace-offset' -5 -8 |
744 | `cperl-label-offset' -5 -8 |
745 | |
746 | If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'. |
