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 mode-compile. In the |
4633a7c4 |
71 | ;;;; hairy version font-lock is on, but you should activate imenu |
29043b61 |
72 | ;;;; yourself (note that mode-compile is not standard yet). Well, you |
4633a7c4 |
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 | |
4633a7c4 |
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) |
c07a80fd |
186 | ;;; Bug with auto-filling comments started with "##" corrected. |

403 | \(and almost as readable) expression. |
404 | |
405 | Try to help it: add comments with embedded quotes to fix CPerl |
406 | misunderstandings about the end of quotation: |
407 | |
408 | $a='500$'; # '; |
409 | |
410 | You won't need it too often. The reason: $ \"quotes\" the following |
411 | character (this saves a life a lot of times in CPerl), thus due to |
412 | Emacs parsing rules it does not consider tick after the dollar as a |
413 | closing one, but as a usual character. |
414 | |
415 | Now the indentation code is pretty wise. The only drawback is that it |
416 | relies on Emacs parsing to find matching parentheses. And Emacs |
417 | *cannot* match parentheses in Perl 100% correctly. So |
418 | 1 if s#//#/#; |
419 | will not break indentation, but |
420 | 1 if ( s#//#/# ); |
421 | will. |
422 | |
423 | If you still get wrong indentation in situation that you think the |
424 | code should be able to parse, try: |
425 | |
426 | a) Check what Emacs thinks about balance of your parentheses. |
427 | b) Supply the code to me (IZ). |
428 | |
429 | Pods are treated _very_ rudimentally. Here-documents are not treated |
430 | at all (except highlighting and inhibiting indentation). (This may |
431 | change some time. RMS approved making syntax lookup recognize text |
432 | attributes, but volonteers are needed to change Emacs C code.) |
433 | |
434 | To speed up coloring the following compromises exist: |
435 | a) sub in $mypackage::sub may be highlighted. |
436 | b) -z in [a-z] may be highlighted. |
437 | c) if your regexp contains a keyword (like \"s\"), it may be highlighted. |

660 | Expression and list commands understand all C brackets. |
661 | Tab indents for Perl code. |
662 | Paragraphs are separated by blank lines only. |
663 | Delete converts tabs to spaces as it moves back. |
664 | |
665 | Various characters in Perl almost always come in pairs: {}, (), [], |
666 | sometimes <>. When the user types the first, she gets the second as |
667 | well, with optional special formatting done on {}. (Disabled by |
668 | default.) You can always quote (with \\[quoted-insert]) the left |
669 | \"paren\" to avoid the expansion. The processing of < is special, |
670 | since most the time you mean \"less\". Cperl mode tries to guess |
671 | whether you want to type pair <>, and inserts is if it |
672 | appropriate. You can set `cperl-electric-parens' to the string that |
673 | contains the parenths from the above list you want to be electrical. |
674 | |
675 | CPerl mode provides expansion of the Perl control constructs: |
676 | if, else, elsif, unless, while, until, for, and foreach. |
677 | =========(Disabled by default, see `cperl-electric-keywords'.) |
678 | The user types the keyword immediately followed by a space, which causes |
679 | the construct to be expanded, and the user is positioned where she is most |
680 | likely to want to be. |
681 | eg. when the user types a space following \"if\" the following appears in |
682 | the buffer: |
683 | if () { or if () |
684 | } { |
685 | } |
686 | and the cursor is between the parentheses. The user can then type some |
687 | boolean expression within the parens. Having done that, typing |
688 | \\[cperl-linefeed] places you, appropriately indented on a new line |
689 | between the braces. If CPerl decides that you want to insert |
690 | \"English\" style construct like |
691 | bite if angry; |
692 | it will not do any expansion. See also help on variable |
693 | `cperl-extra-newline-before-brace'. |
694 | |
695 | \\[cperl-linefeed] is a convinience replacement for typing carriage |
696 | return. It places you in the next line with proper indentation, or if |
697 | you type it inside the inline block of control construct, like |
698 | foreach (@lines) {print; print} |
699 | and you are on a boundary of a statement inside braces, it will |
700 | transform the construct into a multiline and will place you into an |
701 | apporpriately indented blank line. If you need a usual |
702 | `newline-and-indent' behaviour, it is on \\[newline-and-indent], |
703 | see documentation on `cperl-electric-linefeed'. |

710 | that contains parentheses that should be electric in CPerl, setting |
711 | `cperl-electric-keywords' enables electric expansion of control |
712 | structures in CPerl. `cperl-electric-linefeed' governs which one of |
713 | two linefeed behavior is preferable. You can enable all these options |
714 | simultaneously (recommended mode of use) by setting `cperl-hairy' to |
715 | t. In this case you can switch separate options off by setting them |
716 | to `null'. |

729 | Variables controlling indentation style: |
730 | `cperl-tab-always-indent' |
731 | Non-nil means TAB in CPerl mode should always reindent the current line, |
732 | regardless of where in the line point is when the TAB command is used. |
733 | `cperl-auto-newline' |
734 | Non-nil means automatically newline before and after braces, |
735 | and after colons and semicolons, inserted in Perl code. |
736 | `cperl-indent-level' |
737 | Indentation of Perl statements within surrounding block. |
738 | The surrounding block's indentation is the indentation |
739 | of the line on which the open-brace appears. |
740 | `cperl-continued-statement-offset' |
741 | Extra indentation given to a substatement, such as the |
742 | then-clause of an if, or body of a while, or just a statement continuation. |
743 | `cperl-continued-brace-offset' |
744 | Extra indentation given to a brace that starts a substatement. |
745 | This is in addition to `cperl-continued-statement-offset'. |
746 | `cperl-brace-offset' |
747 | Extra indentation for line if it starts with an open brace. |
748 | `cperl-brace-imaginary-offset' |
749 | An open brace following other text is treated as if it the line started |
750 | this far to the right of the actual line indentation. |
751 | `cperl-label-offset' |
752 | Extra indentation for line that is a label. |
753 | `cperl-min-label-indent' |
754 | Minimal indentation for line that is a label. |
755 | |
756 | Settings for K&R and BSD indentation styles are |
757 | `cperl-indent-level' 5 8 |
758 | `cperl-continued-statement-offset' 5 8 |
759 | `cperl-brace-offset' -5 -8 |
760 | `cperl-label-offset' -5 -8 |
761 | |
762 | If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'. |
