ebcd4dbc | 76 | ;;; The mode information (on C-h m) provides some customization help. |
4633a7c4 | 77 | ;;; If you use font-lock feature of this mode, it is advisable to use |
6c72d195 | 78 | ;;; either lazy-lock-mode or fast-lock-mode. I prefer lazy-lock. |
4633a7c4 LW |
79 | |
80 | ;;; Faces used now: three faces for first-class and second-class keywords | |
81 | ;;; and control flow words, one for each: comments, string, labels, | |
82 | ;;; functions definitions and packages, arrays, hashes, and variable | |
6c72d195 IZ |
83 | ;;; definitions. If you do not see all these faces, your font-lock does |
84 | ;;; not define them, so you need to define them manually. Maybe you have | |
85 | ;;; an obsolete font-lock from 19.28 or earlier. Upgrade. | |
4633a7c4 | 86 | |
55497cff | 87 | ;;; If you have a grayscale monitor, and do not have the variable |
4633a7c4 LW |
88 | ;;; font-lock-display-type bound to 'grayscale, insert |
89 | ||
90 | ;;; (setq font-lock-display-type 'grayscale) | |
91 | ||
6c72d195 | 92 | ;;; into your .emacs file (this is relevant before RMS Emacs 20). |
4633a7c4 | 93 | |
6c72d195 | 94 | ;;;; This mode supports font-lock, imenu and mode-compile. In the |
4633a7c4 | 95 | ;;;; hairy version font-lock is on, but you should activate imenu |
6c72d195 | 96 | ;;;; yourself (note that mode-compile is not standard yet). Well, you |
4633a7c4 LW |
97 | ;;;; can use imenu from keyboard anyway (M-x imenu), but it is better |
98 | ;;;; to bind it like that: | |
99 | ||
100 | ;; (define-key global-map [M-S-down-mouse-3] 'imenu) | |
101 | ||
102 | ;;; In fact the version of font-lock that this version supports can be | |
103 | ;;; much newer than the version you actually have. This means that a | |
104 | ;;; lot of faces can be set up, but are not visible on your screen | |
105 | ;;; since the coloring rules for this faces are not defined. | |
106 | ||
4633a7c4 LW |
107 | ;;; Updates: ======================================== |
108 | ||
109 | ;;; Made less hairy by default: parentheses not electric, | |
110 | ;;; linefeed not magic. Bug with abbrev-mode corrected. | |
111 | ||
112 | ;;;; After 1.4: | |
113 | ;;; Better indentation: | |
114 | ;;; subs inside braces should work now, | |
115 | ;;; Toplevel braces obey customization. | |
116 | ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment | |
117 | ;;; moves cursor to a correct place. | |
118 | ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-( | |
119 | ;;; (50 secs on DB::DB (sub of 430 lines), 486/66) | |
120 | ;;; Minor documentation fixes. | |
121 | ;;; Imenu understands packages as prefixes (including nested). | |
122 | ;;; Hairy options can be switched off one-by-one by setting to null. | |
123 | ;;; Names of functions and variables changed to conform to `cperl-' style. | |
124 | ||
125 | ;;;; After 1.5: | |
126 | ;;; Some bugs with indentation of labels (and embedded subs) corrected. | |
127 | ;;; `cperl-indent-region' done (slow :-()). | |
128 | ;;; `cperl-fill-paragraph' done. | |
129 | ;;; Better package support for `imenu'. | |
130 | ;;; Progress indicator for indentation (with `imenu' loaded). | |
131 | ;;; `Cperl-set' was busted, now setting the individual hairy option | |
132 | ;;; should be better. | |
133 | ||
134 | ;;;; After 1.6: | |
135 | ;;; `cperl-set-style' done. | |
136 | ;;; `cperl-check-syntax' done. | |
137 | ;;; Menu done. | |
138 | ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'. | |
139 | ;;; Bugs with `cperl-auto-newline' corrected. | |
140 | ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation | |
141 | ;;; like $hash{. | |
142 | ||
143 | ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de): | |
144 | ;;; - use `next-command-event', if `next-command-events' does not exist | |
145 | ;;; - use `find-face' as def. of `is-face' | |
146 | ;;; - corrected def. of `x-color-defined-p' | |
147 | ;;; - added const defs for font-lock-comment-face, | |
148 | ;;; font-lock-keyword-face and font-lock-function-name-face | |
149 | ;;; - added def. of font-lock-variable-name-face | |
150 | ;;; - added (require 'easymenu) inside an `eval-when-compile' | |
151 | ;;; - replaced 4-argument `substitute-key-definition' with ordinary | |
152 | ;;; `define-key's | |
153 | ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'. | |
154 | ;;; Todo (at least): | |
155 | ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz) | |
156 | ;;; for portable code? | |
157 | ;;; - should `cperl-mode' do a | |
158 | ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu)) | |
159 | ;;; or should this be left to the user's `cperl-mode-hook'? | |
160 | ||
161 | ;;; Some bugs introduced by the above fix corrected (IZ ;-). | |
162 | ;;; Some bugs under XEmacs introduced by the correction corrected. | |
163 | ||
164 | ;;; Some more can remain since there are two many different variants. | |
165 | ;;; Please feedback! | |
166 | ||
167 | ;;; We do not support fontification of arrays and hashes under | |
168 | ;;; obsolete font-lock any more. Upgrade. | |
169 | ||
170 | ;;;; after 1.8 Minor bug with parentheses. | |
171 | ;;;; after 1.9 Improvements from Joe Marzot. | |
172 | ;;;; after 1.10 | |
173 | ;;; Does not need easymenu to compile under XEmacs. | |
174 | ;;; `vc-insert-headers' should work better. | |
175 | ;;; Should work with 19.29 and 19.12. | |
176 | ;;; Small improvements to fontification. | |
177 | ;;; Expansion of keywords does not depend on C-? being backspace. | |
178 | ||
179 | ;;; after 1.10+ | |
180 | ;;; 19.29 and 19.12 supported. | |
181 | ;;; `cperl-font-lock-enhanced' deprecated. Use font-lock-extra.el. | |
182 | ;;; Support for font-lock-extra.el. | |
183 | ||
184 | ;;;; After 1.11: | |
185 | ;;; Tools submenu. | |
186 | ;;; Support for perl5-info. | |
187 | ;;; `imenu-go-find-at-position' in Tools requires imenu-go.el (see hints above) | |
188 | ;;; Imenu entries do not work with stock imenu.el. Patch sent to maintainers. | |
189 | ;;; Fontifies `require a if b;', __DATA__. | |
190 | ;;; Arglist for auto-fill-mode was incorrect. | |
191 | ||
192 | ;;;; After 1.12: | |
193 | ;;; `cperl-lineup-step' and `cperl-lineup' added: lineup constructions | |
194 | ;;; vertically. | |
195 | ;;; `cperl-do-auto-fill' updated for 19.29 style. | |
196 | ;;; `cperl-info-on-command' now has a default. | |
197 | ;;; Workaround for broken C-h on XEmacs. | |
198 | ;;; VC strings escaped. | |
199 | ;;; C-h f now may prompt for function name instead of going on, | |
200 | ;;; controlled by `cperl-info-on-command-no-prompt'. | |
201 | ||
202 | ;;;; After 1.13: | |
203 | ;;; Msb buffer list includes perl files | |
204 | ;;; Indent-for-comment uses indent-to | |
205 | ;;; Can write tag files using etags. | |
206 | ||
207 | ;;;; After 1.14: | |
208 | ;;; Recognizes (tries to ;-) {...} which are not blocks during indentation. | |
209 | ;;; `cperl-close-paren-offset' affects ?\] too (and ?\} if not block) | |
c07a80fd | 210 | ;;; Bug with auto-filling comments started with "##" corrected. |
211 | ||

245 | ;;;; After 1.17: | |

248 | ;;; Only one here-doc-tag per line is supported, and one in comment | |
249 | ;;; or a string may break fontification. | |
250 | ;;; POD headers were supposed to fill one line only. | |
251 | ||
252 | ;;;; After 1.18: | |
253 | ;;; `font-lock-keywords' were set in 19.30 style _always_. Current scheme | |
254 | ;;; may break under XEmacs. | |
255 | ;;; `cperl-calculate-indent' dis suppose that `parse-start' was defined. | |
256 | ;;; `fontified' tag is added to fontified text as well as `lazy-lock' (for | |

258 | ;;; something nevertheless :-(). | |
259 | ;;; Will not indent something inside pod and here-documents. | |

266 | ;;; Some misprints in docs corrected. | |
267 | ;;; Now $a{-text} and -text => "blah" are fontified as strings too. | |
268 | ;;; Now the pod search is much stricter, so it can help you to find | |
269 | ;;; pod sections which are broken because of whitespace before =blah | |
270 | ;;; - just observe the fontification. | |
271 | ||
9ea28adb | 272 | ;;;; After 1.20 |
273 | ;;; Anonymous subs are indented with respect to the level of | |
274 | ;;; indentation of `sub' now. | |
275 | ;;; {} is recognized as hash after `bless' and `return'. | |
276 | ;;; Anonymous subs are split by `cperl-linefeed' as well. | |
277 | ;;; Electric parens embrace a region if present. | |
278 | ;;; To make `cperl-auto-newline' useful, | |
279 | ;;; `cperl-auto-newline-after-colon' is introduced. | |

290 | ;;; {} is recognized as expression after `tr' and friends. | |

296 | ;;; Class viewer based on TAGS files. Does not trace @ISA so far. | |

307 | ||
499d5216 IZ |
308 | ;;;; After 1.24 |
309 | ;;; New location for info-files mentioned, | |

55497cff | 313 | ;;;; After 1.25 (probably not...) |
499d5216 IZ |
314 | ;;; `cperl-info-page' introduced. |

317 | ;;; Here documents delimiters better recognized | |
318 | ;;; (empty one, and non-alphanums in quotes handled). May be wrong with 1<<14? | |

320 | ;;; imenu scan removes text-properties, for better debugging | |
321 | ;;; - but the bug is in 19.31 imenu. | |
322 | ;;; formats highlighted by font-lock and prescan, embedded comments | |

324 | ;;; POD/friends scan merged in one pass. | |
325 | ;;; Syntax class is not used for analyzing the code, only char-syntax | |

499d5216 IZ |

331 | ;;; When search for here-documents, we ignore commented << in simplest cases. | |
332 | ;;; `cperl-get-help' added, available on C-h v and from menu. | |
333 | ;;; Auto-help added. Default with `cperl-hairy', switchable on/off | |
334 | ;;; with startup variable `cperl-lazy-help-time' and from | |
335 | ;;; menu. Requires `run-with-idle-timer'. | |
336 | ;;; Highlighting of @abc{@efg} was wrong - interchanged two regexps. | |
337 | ||
338 | ;;;; After 1.27 | |
339 | ;;; Indentation: At toplevel after a label - fixed. | |
340 | ;;; 1.27 was put to archives in binary mode ===> DOSish :-( | |
341 | ||
342 | ;;;; After 1.28 | |
343 | ;;; Thanks to Martin Buchholz <mrb@Eng.Sun.COM>: misprints in | |
344 | ;;; comments and docstrings corrected, XEmacs support cleaned up. | |
345 | ;;; The closing parenths would enclose the region into matching | |

349 | ||
5f05dabc | 350 | ;;;; After 1.29 |

1322 | ||
1323 | Emacs had a _very_ restricted syntax parsing engine until RMS's Emacs | |
1324 | 20.1. Most problems below are corrected starting from this version of | |
1325 | Emacs, and all of them should go with (future) RMS's version 20.3. | |
1326 | ||
1327 | Note that even with newer Emacsen interaction of `font-lock' and | |
1328 | syntaxification is not cleaned up. You may get slightly different | |
1329 | colors basing on the order of fontification and syntaxification. This | |
1330 | might be corrected by setting `cperl-syntaxify-by-font-lock' to t, but | |
1331 | the corresponding code is still extremely buggy. | |
1332 | ||
1333 | Even with older Emacsen CPerl mode tries to corrects some Emacs | |
1334 | misunderstandings, however, for efficiency reasons the degree of | |
1335 | correction is different for different operations. The partially | |
1336 | corrected problems are: POD sections, here-documents, regexps. The | |
1337 | operations are: highlighting, indentation, electric keywords, electric | |
1338 | braces. | |
c07a80fd | 1339 | |
1340 | This may be confusing, since the regexp s#//#/#\; may be highlighted | |
55497cff | 1341 | as a comment, but it will be recognized as a regexp by the indentation |
6c72d195 | 1342 | code. Or the opposite case, when a pod section is highlighted, but |
ebcd4dbc IZ |
1343 | may break the indentation of the following code (though indentation |
1344 | should work if the balance of delimiters is not broken by POD). | |
c07a80fd | 1345 | |
1346 | The main trick (to make $ a \"backslash\") makes constructions like | |
6c72d195 | 1347 | ${aaa} look like unbalanced braces. The only trick I can think of is |
c07a80fd | 1348 | to insert it as $ {aaa} (legal in perl5, not in perl4). |
1349 | ||
1350 | Similar problems arise in regexps, when /(\\s|$)/ should be rewritten | |
6c72d195 IZ |
1351 | as /($|\\s)/. Note that such a transposition is not always possible. |
1352 | ||
1353 | The solution is to upgrade your Emacs. Note that RMS's 20.2 has some | |
1354 | bugs related to `syntax-table' text properties. Patches are available | |
1355 | on the main CPerl download site, and on CPAN. | |
1356 | ||
1357 | If these bugs cannot be fixed on your machine (say, you have an inferior | |
1358 | environment and cannot recompile), you may still disable all the fancy stuff | |
1359 | via `cperl-use-syntax-table-text-property'." ) | |

1365 | Most of the time, if you write your own code, you may find an equivalent |
1366 | \(and almost as readable) expression (what is discussed below is usually | |

1373 | ||
6c72d195 | 1374 | You won't need it too often. The reason: $ \"quotes\" the following |
c07a80fd | 1375 | character (this saves a life a lot of times in CPerl), thus due to |
ebcd4dbc | 1376 | Emacs parsing rules it does not consider tick (i.e., ' ) after a |
6c72d195 IZ |
1377 | dollar as a closing one, but as a usual character. This is usually |
1378 | correct, but not in the above context. | |
c07a80fd | 1379 | |
6c72d195 IZ |
1380 | Even with older Emacsen the indentation code is pretty wise. The only |
1381 | drawback is that it relied on Emacs parsing to find matching | |
1382 | parentheses. And Emacs *could not* match parentheses in Perl 100% | |
1383 | correctly. So | |
c07a80fd | 1384 | 1 if s#//#/#; |
6c72d195 | 1385 | would not break indentation, but |
c07a80fd | 1386 | 1 if ( s#//#/# ); |

5f05dabc | 1392 | |
c07a80fd | 1393 | If you still get wrong indentation in situation that you think the |
1394 | code should be able to parse, try: | |
1395 | ||
1396 | a) Check what Emacs thinks about balance of your parentheses. | |
1397 | b) Supply the code to me (IZ). | |

1399 | Pods were treated _very_ rudimentally. Here-documents were not |
1400 | treated at all (except highlighting and inhibiting indentation). Upgrade. | |
c07a80fd | 1401 | |
1402 | To speed up coloring the following compromises exist: | |
1403 | a) sub in $mypackage::sub may be highlighted. | |
1404 | b) -z in [a-z] may be highlighted. | |
1405 | c) if your regexp contains a keyword (like \"s\"), it may be highlighted. | |

1492 | "This is an incomplete compendium of what is available in other parts | |
1493 | of CPerl documentation. (Please inform me if I skept anything.) | |
1494 | ||
1495 | There is a perception that CPerl is slower than alternatives. This part | |
1496 | of documentation is designed to overcome this misconception. | |
1497 | ||
1498 | *By default* CPerl tries to enable the most comfortable settings. | |
1499 | From most points of view, correctly working package is infinitely more | |
1500 | comfortable than a non-correctly working one, thus by default CPerl | |
1501 | prefers correctness over speed. Below is the guide how to change | |
1502 | settings if your preferences are different. | |
1503 | ||
1504 | A) Speed of loading the file. When loading file, CPerl may perform a | |
1505 | scan which indicates places which cannot be parsed by primitive Emacs | |
1506 | syntax-parsing routines, and marks them up so that either | |
1507 | ||
1508 | A1) CPerl may work around these deficiencies (for big chunks, mostly | |
1509 | PODs and HERE-documents), or | |
1510 | A2) On capable Emaxen CPerl will use improved syntax-handlings | |
1511 | which reads mark-up hints directly. | |
1512 | ||
1513 | The scan in case A2 is much more comprehensive, thus may be slower. | |
1514 | ||
1515 | User can disable syntax-engine-helping scan of A2 by setting | |
1516 | `cperl-use-syntax-table-text-property' | |
1517 | variable to nil (if it is set to t). | |
1518 | ||
1519 | One can disable the scan altogether (both A1 and A2) by setting | |
1520 | `cperl-pod-here-scan' | |
1521 | to nil. | |
1522 | ||
1523 | B) Speed of editing operations. | |
1524 | ||
1525 | One can add a (minor) speedup to editing operations by setting | |
1526 | `cperl-use-syntax-table-text-property' | |
1527 | variable to nil (if it is set to t). This will disable | |
1528 | syntax-engine-helping scan, thus will make many more Perl | |
1529 | constructs be wrongly recognized by CPerl, thus may lead to | |
1530 | wrongly matched parentheses, wrong indentation, etc. | |
20675f5d IZ |
1531 | |
1532 | One can unset `cperl-syntaxify-unwind'. This might speed up editing | |
1533 | of, say, long POD sections. | |

1895 | Delete converts tabs to spaces as it moves back. | |
1896 | ||
1897 | Various characters in Perl almost always come in pairs: {}, (), [], | |
6c72d195 | 1898 | sometimes <>. When the user types the first, she gets the second as |
4633a7c4 LW |
1899 | well, with optional special formatting done on {}. (Disabled by |
1900 | default.) You can always quote (with \\[quoted-insert]) the left | |
6c72d195 IZ |
1901 | \"paren\" to avoid the expansion. The processing of < is special, |
1902 | since most the time you mean \"less\". Cperl mode tries to guess | |
4633a7c4 | 1903 | whether you want to type pair <>, and inserts is if it |
6c72d195 | 1904 | appropriate. You can set `cperl-electric-parens-string' to the string that |
4633a7c4 | 1905 | contains the parenths from the above list you want to be electrical. |
9ea28adb | 1906 | Electricity of parenths is controlled by `cperl-electric-parens'. |
1907 | You may also set `cperl-electric-parens-mark' to have electric parens | |
1908 | look for active mark and \"embrace\" a region if possible.' | |
4633a7c4 LW |
1909 | |
1910 | CPerl mode provides expansion of the Perl control constructs: | |
6c72d195 IZ |
1911 | |
1912 | if, else, elsif, unless, while, until, continue, do, | |
1913 | for, foreach, formy and foreachmy. | |
1914 | ||
1915 | and POD directives (Disabled by default, see `cperl-electric-keywords'.) | |
1916 | ||
1917 | The user types the keyword immediately followed by a space, which | |
1918 | causes the construct to be expanded, and the point is positioned where | |
1919 | she is most likely to want to be. eg. when the user types a space | |
1920 | following \"if\" the following appears in the buffer: if () { or if () | |
1921 | } { } and the cursor is between the parentheses. The user can then | |
1922 | type some boolean expression within the parens. Having done that, | |
1923 | typing \\[cperl-linefeed] places you - appropriately indented - on a | |
1924 | new line between the braces (if you typed \\[cperl-linefeed] in a POD | |
1925 | directive line, then appropriate number of new lines is inserted). | |
1926 | ||
1927 | If CPerl decides that you want to insert \"English\" style construct like | |
1928 | ||
4633a7c4 | 1929 | bite if angry; |

1931 | it will not do any expansion. See also help on variable | |
1932 | `cperl-extra-newline-before-brace'. (Note that one can switch the | |
1933 | help message on expansion by setting `cperl-message-electric-keyword' | |
1934 | to nil.) | |
4633a7c4 | 1935 | |
55497cff | 1936 | \\[cperl-linefeed] is a convenience replacement for typing carriage |
6c72d195 | 1937 | return. It places you in the next line with proper indentation, or if |
4633a7c4 | 1938 | you type it inside the inline block of control construct, like |
6c72d195 | 1939 | |
4633a7c4 | 1940 | foreach (@lines) {print; print} |
6c72d195 | 1941 | |
4633a7c4 LW |
1942 | and you are on a boundary of a statement inside braces, it will |
1943 | transform the construct into a multiline and will place you into an | |
6c72d195 | 1944 | appropriately indented blank line. If you need a usual |
4633a7c4 LW |
1945 | `newline-and-indent' behaviour, it is on \\[newline-and-indent], |

6c72d195 IZ |
2002 | `cperl-indent-left-aligned-comments' |

2004 | `cperl-auto-newline' |
2005 | Non-nil means automatically newline before and after braces, | |
6c72d195 | 2006 | and after colons and semicolons, inserted in Perl code. The following |
9ea28adb | 2007 | \\[cperl-electric-backspace] will remove the inserted whitespace. |

2009 | `cperl-auto-newline-after-colon' set. | |
2010 | `cperl-auto-newline-after-colon' | |
2011 | Non-nil means automatically newline even after colons. | |

4633a7c4 LW |
2013 | `cperl-indent-level' |
2014 | Indentation of Perl statements within surrounding block. | |
2015 | The surrounding block's indentation is the indentation | |
2016 | of the line on which the open-brace appears. | |
2017 | `cperl-continued-statement-offset' | |
2018 | Extra indentation given to a substatement, such as the | |
2019 | then-clause of an if, or body of a while, or just a statement continuation. | |
2020 | `cperl-continued-brace-offset' | |
2021 | Extra indentation given to a brace that starts a substatement. | |
2022 | This is in addition to `cperl-continued-statement-offset'. | |
2023 | `cperl-brace-offset' | |
2024 | Extra indentation for line if it starts with an open brace. | |
2025 | `cperl-brace-imaginary-offset' | |
2026 | An open brace following other text is treated as if it the line started | |
2027 | this far to the right of the actual line indentation. | |
2028 | `cperl-label-offset' | |
2029 | Extra indentation for line that is a label. | |
