75 | ;; The mode information (on C-h m) provides some customization help. |
76 | ;; If you use font-lock feature of this mode, it is advisable to use | |
77 | ;; either lazy-lock-mode or fast-lock-mode. I prefer lazy-lock. | |
4633a7c4 | 78 | |
8cfd7987 JH |
79 | ;; Faces used now: three faces for first-class and second-class keywords |
80 | ;; and control flow words, one for each: comments, string, labels, | |
81 | ;; functions definitions and packages, arrays, hashes, and variable | |
82 | ;; definitions. If you do not see all these faces, your font-lock does | |
83 | ;; not define them, so you need to define them manually. | |
84 | ;; Maybe you have an obsolete font-lock from 19.28 or earlier. Upgrade. | |
4633a7c4 | 85 | |
8cfd7987 JH |
86 | ;; If you have a grayscale monitor, and do not have the variable |

93 | ;; This mode supports font-lock, imenu and mode-compile. In the |
94 | ;; hairy version font-lock is on, but you should activate imenu | |
95 | ;; yourself (note that mode-compile is not standard yet). Well, you | |
96 | ;; can use imenu from keyboard anyway (M-x imenu), but it is better | |
97 | ;; to bind it like that: | |
4633a7c4 LW |
98 | |
99 | ;; (define-key global-map [M-S-down-mouse-3] 'imenu) | |
100 | ||
8cfd7987 JH |
101 | ;;; Font lock bugs as of v4.32: |
102 | ||
103 | ;; The following kinds of Perl code erroneously start strings: | |
104 | ;; \$` \$' \$" | |
105 | ;; $opt::s $opt_s $opt{s} (s => ...) /\s+.../ | |
106 | ;; likewise with m, tr, y, q, qX instead of s | |
107 | ||
4633a7c4 LW |
108 | ;;; In fact the version of font-lock that this version supports can be |
109 | ;;; much newer than the version you actually have. This means that a | |
110 | ;;; lot of faces can be set up, but are not visible on your screen | |
111 | ;;; since the coloring rules for this faces are not defined. | |
112 | ||
4633a7c4 LW |
113 | ;;; Updates: ======================================== |
114 | ||
8cfd7987 | 115 | ;;; Made less hairy by default: parentheses not electric, |
4633a7c4 LW |
116 | ;;; linefeed not magic. Bug with abbrev-mode corrected. |
117 | ||
118 | ;;;; After 1.4: | |
119 | ;;; Better indentation: | |
8cfd7987 | 120 | ;;; subs inside braces should work now, |
4633a7c4 LW |
121 | ;;; Toplevel braces obey customization. |
122 | ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment | |
123 | ;;; moves cursor to a correct place. | |
8cfd7987 | 124 | ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-( |
4633a7c4 LW |
125 | ;;; (50 secs on DB::DB (sub of 430 lines), 486/66) |
126 | ;;; Minor documentation fixes. | |
127 | ;;; Imenu understands packages as prefixes (including nested). | |
128 | ;;; Hairy options can be switched off one-by-one by setting to null. | |
129 | ;;; Names of functions and variables changed to conform to `cperl-' style. | |
130 | ||
131 | ;;;; After 1.5: | |
132 | ;;; Some bugs with indentation of labels (and embedded subs) corrected. | |
133 | ;;; `cperl-indent-region' done (slow :-()). | |
134 | ;;; `cperl-fill-paragraph' done. | |
135 | ;;; Better package support for `imenu'. | |
136 | ;;; Progress indicator for indentation (with `imenu' loaded). | |
8cfd7987 | 137 | ;;; `Cperl-set' was busted, now setting the individual hairy option |
4633a7c4 LW |
138 | ;;; should be better. |
139 | ||
140 | ;;;; After 1.6: | |
141 | ;;; `cperl-set-style' done. | |
142 | ;;; `cperl-check-syntax' done. | |
143 | ;;; Menu done. | |
144 | ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'. | |
145 | ;;; Bugs with `cperl-auto-newline' corrected. | |
8cfd7987 | 146 | ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation |
4633a7c4 LW |
147 | ;;; like $hash{. |
148 | ||
149 | ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de): | |
150 | ;;; - use `next-command-event', if `next-command-events' does not exist | |
151 | ;;; - use `find-face' as def. of `is-face' | |
152 | ;;; - corrected def. of `x-color-defined-p' | |
153 | ;;; - added const defs for font-lock-comment-face, | |
154 | ;;; font-lock-keyword-face and font-lock-function-name-face | |
155 | ;;; - added def. of font-lock-variable-name-face | |
156 | ;;; - added (require 'easymenu) inside an `eval-when-compile' | |
157 | ;;; - replaced 4-argument `substitute-key-definition' with ordinary | |
158 | ;;; `define-key's | |
159 | ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'. | |
160 | ;;; Todo (at least): | |
161 | ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz) | |
162 | ;;; for portable code? | |
8cfd7987 | 163 | ;;; - should `cperl-mode' do a |
4633a7c4 LW |
164 | ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu)) |
165 | ;;; or should this be left to the user's `cperl-mode-hook'? | |
166 | ||
167 | ;;; Some bugs introduced by the above fix corrected (IZ ;-). | |
168 | ;;; Some bugs under XEmacs introduced by the correction corrected. | |
169 | ||
8cfd7987 | 170 | ;;; Some more can remain since there are two many different variants. |
4633a7c4 LW |
171 | ;;; Please feedback! |
172 | ||
8cfd7987 | 173 | ;;; We do not support fontification of arrays and hashes under |
4633a7c4 LW |
174 | ;;; obsolete font-lock any more. Upgrade. |
175 | ||
176 | ;;;; after 1.8 Minor bug with parentheses. | |
177 | ;;;; after 1.9 Improvements from Joe Marzot. | |
178 | ;;;; after 1.10 | |
179 | ;;; Does not need easymenu to compile under XEmacs. | |
180 | ;;; `vc-insert-headers' should work better. | |
181 | ;;; Should work with 19.29 and 19.12. | |
182 | ;;; Small improvements to fontification. | |
183 | ;;; Expansion of keywords does not depend on C-? being backspace. | |
184 | ||
185 | ;;; after 1.10+ | |
186 | ;;; 19.29 and 19.12 supported. | |
187 | ;;; `cperl-font-lock-enhanced' deprecated. Use font-lock-extra.el. | |
188 | ;;; Support for font-lock-extra.el. | |
189 | ||
190 | ;;;; After 1.11: | |
191 | ;;; Tools submenu. | |
192 | ;;; Support for perl5-info. | |
193 | ;;; `imenu-go-find-at-position' in Tools requires imenu-go.el (see hints above) | |
194 | ;;; Imenu entries do not work with stock imenu.el. Patch sent to maintainers. | |
195 | ;;; Fontifies `require a if b;', __DATA__. | |
196 | ;;; Arglist for auto-fill-mode was incorrect. | |
197 | ||
198 | ;;;; After 1.12: | |
8cfd7987 | 199 | ;;; `cperl-lineup-step' and `cperl-lineup' added: lineup constructions |
4633a7c4 LW |
200 | ;;; vertically. |
201 | ;;; `cperl-do-auto-fill' updated for 19.29 style. | |
202 | ;;; `cperl-info-on-command' now has a default. | |
203 | ;;; Workaround for broken C-h on XEmacs. | |
204 | ;;; VC strings escaped. | |
205 | ;;; C-h f now may prompt for function name instead of going on, | |
206 | ;;; controlled by `cperl-info-on-command-no-prompt'. | |
207 | ||
208 | ;;;; After 1.13: | |
209 | ;;; Msb buffer list includes perl files | |
210 | ;;; Indent-for-comment uses indent-to | |
211 | ;;; Can write tag files using etags. | |
212 | ||
213 | ;;;; After 1.14: | |
214 | ;;; Recognizes (tries to ;-) {...} which are not blocks during indentation. | |
215 | ;;; `cperl-close-paren-offset' affects ?\] too (and ?\} if not block) | |
c07a80fd | 216 | ;;; Bug with auto-filling comments started with "##" corrected. |

265 | ;;; Will not indent something inside pod and here-documents. | |

355 | ||
5f05dabc | 356 | ;;;; After 1.29 |

365 | ||
366 | ;;;; After 1.30 | |

ebcd4dbc IZ |
378 | ;;; Some support for correct indent after here-docs and friends (may |

403 | ;;; `cperl-after-expr-p' is now much smarter after "() {}" and "word {}": | |

406 | ;;; Uses `help-char' (at last!) (disabled, does not work?!) | |
407 | ;;; A couple of regexps where missing _ in character classes. | |
408 | ;;; -s could be considered as start of regexp, 1../blah/ was not, | |

410 | ||
411 | ;;;; After 1.32.2 | |
412 | ;;; "\C-hv" was wrongly "\C-hf" | |
413 | ;;; C-hv was not working on `[index()]' because of [] in skip-chars-*. | |

439 | ;;; Logic of `cperl-indent-exp' changed a little bit, should be more | |
440 | ;;; robust w.r.t. multiline strings. | |
441 | ;;; Recognition of blah'foo takes into account strings. | |
442 | ;;; Added '.al' to the list of Perl extensions. | |

451 | ;;; Knows of `extproc' when under `emx', indents with `__END__' and `__DATA__'. | |
452 | ;;; `cperl-under-as-char' implemented (XEmacs people like broken behaviour). | |
453 | ;;; Beautifier for regexps fixed. | |
454 | ;;; `cperl-beautify-level', `cperl-contract-level' coded | |
455 | ;;; | |
456 | ;;;; Emacs's 20.2 problems: | |

460 | ||
461 | ;;;; After 1.36: | |

1803 | Emacs had a _very_ restricted syntax parsing engine until RMS's Emacs |
1804 | 20.1. Most problems below are corrected starting from this version of | |
8cfd7987 JH |
1805 | Emacs, and all of them should be fixed in RMS's version 20.3. (Or apply |
1806 | patches to Emacs 19.33/34 - see tips.) XEmacs was very backward in | |
1807 | this respect (until 2003). | |
6c72d195 | 1808 | |
7bcea553 IZ |
1809 | Note that even with newer Emacsen in some very rare cases the details |
1810 | of interaction of `font-lock' and syntaxification may be not cleaned | |
1811 | up yet. You may get slightly different colors basing on the order of | |
1812 | fontification and syntaxification. Say, the initial faces is correct, | |
1813 | but editing the buffer breaks this. | |
6c72d195 IZ |
1814 | |
1815 | Even with older Emacsen CPerl mode tries to corrects some Emacs | |
1816 | misunderstandings, however, for efficiency reasons the degree of | |
1817 | correction is different for different operations. The partially | |
1818 | corrected problems are: POD sections, here-documents, regexps. The | |
1819 | operations are: highlighting, indentation, electric keywords, electric | |
1820 | braces. | |
c07a80fd | 1821 | |
1822 | This may be confusing, since the regexp s#//#/#\; may be highlighted | |
55497cff | 1823 | as a comment, but it will be recognized as a regexp by the indentation |
8cfd7987 | 1824 | code. Or the opposite case, when a POD section is highlighted, but |
ebcd4dbc IZ |
1825 | may break the indentation of the following code (though indentation |
1826 | should work if the balance of delimiters is not broken by POD). | |
c07a80fd | 1827 | |
1828 | The main trick (to make $ a \"backslash\") makes constructions like | |
6c72d195 | 1829 | ${aaa} look like unbalanced braces. The only trick I can think of is |
8cfd7987 | 1830 | to insert it as $ {aaa} (legal in perl5, not in perl4). |
c07a80fd | 1831 | |
1832 | Similar problems arise in regexps, when /(\\s|$)/ should be rewritten | |
6c72d195 IZ |
1833 | as /($|\\s)/. Note that such a transposition is not always possible. |

1835 | The solution is to upgrade your Emacs or patch an older one. Note |
1836 | that RMS's 20.2 has some bugs related to `syntax-table' text | |
1837 | properties. Patches are available on the main CPerl download site, | |
1838 | and on CPAN. | |
6c72d195 IZ |
1839 | |
1840 | If these bugs cannot be fixed on your machine (say, you have an inferior | |
1841 | environment and cannot recompile), you may still disable all the fancy stuff | |
8cfd7987 | 1842 | via `cperl-use-syntax-table-text-property'.") |

1858 | ||
6c72d195 | 1859 | You won't need it too often. The reason: $ \"quotes\" the following |
c07a80fd | 1860 | character (this saves a life a lot of times in CPerl), thus due to |
ebcd4dbc | 1861 | Emacs parsing rules it does not consider tick (i.e., ' ) after a |
6c72d195 IZ |
1862 | dollar as a closing one, but as a usual character. This is usually |
1863 | correct, but not in the above context. | |
c07a80fd | 1864 | |
6c72d195 IZ |
1865 | Even with older Emacsen the indentation code is pretty wise. The only |
1866 | drawback is that it relied on Emacs parsing to find matching | |
1867 | parentheses. And Emacs *could not* match parentheses in Perl 100% | |
1868 | correctly. So | |
c07a80fd | 1869 | 1 if s#//#/#; |
6c72d195 | 1870 | would not break indentation, but |
c07a80fd | 1871 | 1 if ( s#//#/# ); |

7bcea553 | 1876 | could confuse CPerl a lot. |
5f05dabc | 1877 | |
c07a80fd | 1878 | If you still get wrong indentation in situation that you think the |
1879 | code should be able to parse, try: | |

1884 | Pods were treated _very_ rudimentally. Here-documents were not |
1885 | treated at all (except highlighting and inhibiting indentation). Upgrade. | |
c07a80fd | 1886 | |
1887 | To speed up coloring the following compromises exist: | |
1888 | a) sub in $mypackage::sub may be highlighted. | |
1889 | b) -z in [a-z] may be highlighted. | |
1890 | c) if your regexp contains a keyword (like \"s\"), it may be highlighted. | |

1985 | "This is an incomplete compendium of what is available in other parts | |
1986 | of CPerl documentation. (Please inform me if I skept anything.) | |
1987 | ||
1988 | There is a perception that CPerl is slower than alternatives. This part | |
1989 | of documentation is designed to overcome this misconception. | |
1990 | ||
1991 | *By default* CPerl tries to enable the most comfortable settings. | |
1992 | From most points of view, correctly working package is infinitely more | |
1993 | comfortable than a non-correctly working one, thus by default CPerl | |
1994 | prefers correctness over speed. Below is the guide how to change | |
1995 | settings if your preferences are different. | |
1996 | ||
1997 | A) Speed of loading the file. When loading file, CPerl may perform a | |
1998 | scan which indicates places which cannot be parsed by primitive Emacs | |
1999 | syntax-parsing routines, and marks them up so that either | |
2000 | ||
2001 | A1) CPerl may work around these deficiencies (for big chunks, mostly | |
2002 | PODs and HERE-documents), or | |
2003 | A2) On capable Emaxen CPerl will use improved syntax-handlings | |
2004 | which reads mark-up hints directly. | |
2005 | ||
2006 | The scan in case A2 is much more comprehensive, thus may be slower. | |
2007 | ||
2008 | User can disable syntax-engine-helping scan of A2 by setting | |
2009 | `cperl-use-syntax-table-text-property' | |
2010 | variable to nil (if it is set to t). | |
2011 | ||
2012 | One can disable the scan altogether (both A1 and A2) by setting | |
2013 | `cperl-pod-here-scan' | |
2014 | to nil. | |
2015 | ||
8cfd7987 | 2016 | B) Speed of editing operations. |
6c72d195 IZ |
2017 | |
2018 | One can add a (minor) speedup to editing operations by setting | |
2019 | `cperl-use-syntax-table-text-property' | |
2020 | variable to nil (if it is set to t). This will disable | |
2021 | syntax-engine-helping scan, thus will make many more Perl | |
2022 | constructs be wrongly recognized by CPerl, thus may lead to | |
2023 | wrongly matched parentheses, wrong indentation, etc. | |
20675f5d IZ |
2024 | |
2025 | One can unset `cperl-syntaxify-unwind'. This might speed up editing | |

2438 | "Major mode for editing Perl code. | |
2439 | Expression and list commands understand all C brackets. | |
2440 | Tab indents for Perl code. | |
2441 | Paragraphs are separated by blank lines only. | |
2442 | Delete converts tabs to spaces as it moves back. | |
2443 | ||
2444 | Various characters in Perl almost always come in pairs: {}, (), [], | |
6c72d195 | 2445 | sometimes <>. When the user types the first, she gets the second as |
4633a7c4 LW |
2446 | well, with optional special formatting done on {}. (Disabled by |
2447 | default.) You can always quote (with \\[quoted-insert]) the left | |
6c72d195 | 2448 | \"paren\" to avoid the expansion. The processing of < is special, |
8cfd7987 | 2449 | since most the time you mean \"less\". CPerl mode tries to guess |
4633a7c4 | 2450 | whether you want to type pair <>, and inserts is if it |
6c72d195 | 2451 | appropriate. You can set `cperl-electric-parens-string' to the string that |
4633a7c4 | 2452 | contains the parenths from the above list you want to be electrical. |
9ea28adb | 2453 | Electricity of parenths is controlled by `cperl-electric-parens'. |
2454 | You may also set `cperl-electric-parens-mark' to have electric parens | |
2455 | look for active mark and \"embrace\" a region if possible.' | |
4633a7c4 LW |
2456 | |
2457 | CPerl mode provides expansion of the Perl control constructs: | |
6c72d195 | 2458 | |
8cfd7987 | 2459 | if, else, elsif, unless, while, until, continue, do, |
6c72d195 IZ |
2460 | for, foreach, formy and foreachmy. |
2461 | ||
2462 | and POD directives (Disabled by default, see `cperl-electric-keywords'.) | |
2463 | ||
2464 | The user types the keyword immediately followed by a space, which | |
2465 | causes the construct to be expanded, and the point is positioned where | |
2466 | she is most likely to want to be. eg. when the user types a space | |
2467 | following \"if\" the following appears in the buffer: if () { or if () | |
2468 | } { } and the cursor is between the parentheses. The user can then | |
2469 | type some boolean expression within the parens. Having done that, | |
2470 | typing \\[cperl-linefeed] places you - appropriately indented - on a | |
2471 | new line between the braces (if you typed \\[cperl-linefeed] in a POD | |
8cfd7987 | 2472 | directive line, then appropriate number of new lines is inserted). |
6c72d195 IZ |
2473 | |
2474 | If CPerl decides that you want to insert \"English\" style construct like | |
2475 | ||
4633a7c4 | 2476 | bite if angry; |
6c72d195 IZ |
2477 | |
2478 | it will not do any expansion. See also help on variable | |
2479 | `cperl-extra-newline-before-brace'. (Note that one can switch the | |
2480 | help message on expansion by setting `cperl-message-electric-keyword' | |
2481 | to nil.) | |
4633a7c4 | 2482 | |
55497cff | 2483 | \\[cperl-linefeed] is a convenience replacement for typing carriage |
6c72d195 | 2484 | return. It places you in the next line with proper indentation, or if |
4633a7c4 | 2485 | you type it inside the inline block of control construct, like |
6c72d195 | 2486 | |
4633a7c4 | 2487 | foreach (@lines) {print; print} |
6c72d195 | 2488 | |
4633a7c4 LW |
2489 | and you are on a boundary of a statement inside braces, it will |
2490 | transform the construct into a multiline and will place you into an | |
8cfd7987 JH |
2491 | appropriately indented blank line. If you need a usual |
2492 | `newline-and-indent' behaviour, it is on \\[newline-and-indent], | |

2509 | \(see also `cperl-electric-parens-mark' and `cperl-electric-parens'), | |
9ea28adb | 2510 | setting `cperl-electric-keywords' enables electric expansion of |
6c72d195 IZ |
2511 | control structures in CPerl. `cperl-electric-linefeed' governs which |
2512 | one of two linefeed behavior is preferable. You can enable all these | |
9ea28adb | 2513 | options simultaneously (recommended mode of use) by setting |
6c72d195 IZ |
2514 | `cperl-hairy' to t. In this case you can switch separate options off |
2515 | by setting them to `null'. Note that one may undo the extra | |
2516 | whitespace inserted by semis and braces in `auto-newline'-mode by | |
2517 | consequent \\[cperl-electric-backspace]. | |

2521 | These keys run commands `cperl-info-on-current-command' and | |
2522 | `cperl-info-on-command', which one is which is controlled by variable | |
8cfd7987 | 2523 | `cperl-info-on-command-no-prompt' and `cperl-clobber-lisp-bindings' |
6c72d195 | 2524 | \(in turn affected by `cperl-hairy'). |

6c72d195 IZ |
2530 | It is possible to show this help automatically after some idle time. |
2531 | This is regulated by variable `cperl-lazy-help-time'. Default with | |
2532 | `cperl-hairy' (if the value of `cperl-lazy-help-time' is nil) is 5 | |
2533 | secs idle time . It is also possible to switch this on/off from the | |

2545 | Variables controlling indentation style: |
2546 | `cperl-tab-always-indent' | |
2547 | Non-nil means TAB in CPerl mode should always reindent the current line, | |
2548 | regardless of where in the line point is when the TAB command is used. | |
6c72d195 IZ |
2549 | `cperl-indent-left-aligned-comments' |
2550 | Non-nil means that the comment starting in leftmost column should indent. | |
4633a7c4 LW |
2551 | `cperl-auto-newline' |
2552 | Non-nil means automatically newline before and after braces, | |
6c72d195 | 2553 | and after colons and semicolons, inserted in Perl code. The following |
9ea28adb | 2554 | \\[cperl-electric-backspace] will remove the inserted whitespace. |
8cfd7987 JH |
2555 | Insertion after colons requires both this variable and |
2556 | `cperl-auto-newline-after-colon' set. | |
9ea28adb | 2557 | `cperl-auto-newline-after-colon' |
2558 | Non-nil means automatically newline even after colons. | |
2559 | Subject to `cperl-auto-newline' setting. | |
4633a7c4 LW |
2560 | `cperl-indent-level' |
2561 | Indentation of Perl statements within surrounding block. | |
2562 | The surrounding block's indentation is the indentation | |
2563 | of the line on which the open-brace appears. | |
2564 | `cperl-continued-statement-offset' | |
2565 | Extra indentation given to a substatement, such as the | |
2566 | then-clause of an if, or body of a while, or just a statement continuation. | |
2567 | `cperl-continued-brace-offset' | |
2568 | Extra indentation given to a brace that starts a substatement. | |
2569 | This is in addition to `cperl-continued-statement-offset'. | |
2570 | `cperl-brace-offset' | |
2571 | Extra indentation for line if it starts with an open brace. | |
2572 | `cperl-brace-imaginary-offset' | |
2573 | An open brace following other text is treated as if it the line started | |
2574 | this far to the right of the actual line indentation. | |
2575 | `cperl-label-offset' | |
2576 | Extra indentation for line that is a label. | |
2577 | `cperl-min-label-indent' | |
2578 | Minimal indentation for line that is a label. | |
2579 | ||
2580 | Settings for K&R and BSD indentation styles are | |
2581 | `cperl-indent-level' 5 8 | |
2582 | `cperl-continued-statement-offset' 5 8 | |
2583 | `cperl-brace-offset' -5 -8 | |
2584 | `cperl-label-offset' -5 -8 | |
2585 | ||
6c72d195 IZ |
2586 | CPerl knows several indentation styles, and may bulk set the |
2587 | corresponding variables. Use \\[cperl-set-style] to do this. Use | |
2588 | \\[cperl-set-style-back] to restore the memorized preexisting values | |
2589 | \(both available from menu). | |
2590 | ||
2591 | If `cperl-indent-level' is 0, the statement after opening brace in | |
8cfd7987 | 2592 | column 0 is indented on |
6c72d195 | 2593 | `cperl-brace-offset'+`cperl-continued-statement-offset'. |
