| 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 | ;;; Tips: ======================================== |
| 84 | |
| 85 | ;;; get newest version of this package from |
| 86 | ;;; ftp://ftp.math.ohio-state.edu/pub/users/ilya/lisp |
| 87 | ;;; and/or |
| 88 | ;;; ftp://ftp.math.ohio-state.edu/pub/users/ilya/perl |
| 89 | |
| 90 | ;;; Get support packages font-lock-extra.el, imenu-go.el from the same place. |
| 91 | ;;; (Look for other files there too... ;-) Get a patch for imenu.el. |
| 92 | |
| 93 | ;;; Get perl5-info from |
| 94 | ;; http://www.metronet.com:70/9/perlinfo/perl5/manual/perl5-info.tar.gz |
| 95 | ;;; (may be quite obsolete, but still useful). |
| 96 | |
| 97 | ;;; If you use imenu-go, run imenu on perl5-info buffer (can do it from |
| 98 | ;;; CPerl menu). |
| 99 | |
| 100 | ;;;; Known problems: ======================================== |
| 101 | |
| 102 | ;;; The very new pod |
| 103 | ;;; features. The rules are: |
| 104 | |
| 105 | ;;; /\n=/ should start comment mode, and |
| 106 | ;;; /\n=cut\s/ should stop comment mode |
| 107 | |
| 108 | ;;; Expansion of keywords tries to detect this kind of commenting, but |
| 109 | ;;; a "=" that starts a perl row (as in multiline comment and here |
| 110 | ;;; document) can confuse it. |
| 111 | |
| 112 | ;;; The main trick (to |
| 113 | ;;; make $ a "backslash") makes constructions like ${aaa} look like |
| 114 | ;;; unbalanced braces. The only trick I can think out is to insert it as |
| 115 | ;;; $ {aaa} (legal in perl5, not in perl4). |
| 116 | |
| 117 | ;;;; Known non-problems: ======================================== |
| 118 | |
| 119 | ;;; Perl quoting rules are too hard for CPerl. Try to help it: add |
| 120 | ;;; comments with embedded quotes to fix CPerl misunderstandings: |
| 121 | |
| 122 | ;;; $a='500$'; # '; |
| 123 | |
| 124 | ;;; You won't need it too often. |
| 125 | |
| 126 | ;;; Now the indentation code is pretty wise. If you still get wrong |
| 127 | ;;; indentation in situation that you think the code should be able to |
| 128 | ;;; parse, try: |
| 129 | |
| 130 | ;;; a) Check what Emacs thinks about balance of your parentheses. |
| 131 | ;;; b) Supply the code to me (IZ). |
| 132 | |
| 133 | ;;; Updates: ======================================== |
| 134 | |
| 135 | ;;; Made less hairy by default: parentheses not electric, |
| 136 | ;;; linefeed not magic. Bug with abbrev-mode corrected. |
| 137 | |
| 138 | ;;;; After 1.4: |
| 139 | ;;; Better indentation: |
| 140 | ;;; subs inside braces should work now, |
| 141 | ;;; Toplevel braces obey customization. |
| 142 | ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment |
| 143 | ;;; moves cursor to a correct place. |
| 144 | ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-( |
| 145 | ;;; (50 secs on DB::DB (sub of 430 lines), 486/66) |
| 146 | ;;; Minor documentation fixes. |
| 147 | ;;; Imenu understands packages as prefixes (including nested). |
| 148 | ;;; Hairy options can be switched off one-by-one by setting to null. |
| 149 | ;;; Names of functions and variables changed to conform to `cperl-' style. |
| 150 | |
| 151 | ;;;; After 1.5: |
| 152 | ;;; Some bugs with indentation of labels (and embedded subs) corrected. |
| 153 | ;;; `cperl-indent-region' done (slow :-()). |
| 154 | ;;; `cperl-fill-paragraph' done. |
| 155 | ;;; Better package support for `imenu'. |
| 156 | ;;; Progress indicator for indentation (with `imenu' loaded). |
| 157 | ;;; `Cperl-set' was busted, now setting the individual hairy option |
| 158 | ;;; should be better. |
| 159 | |
| 160 | ;;;; After 1.6: |
| 161 | ;;; `cperl-set-style' done. |
| 162 | ;;; `cperl-check-syntax' done. |
| 163 | ;;; Menu done. |
| 164 | ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'. |
| 165 | ;;; Bugs with `cperl-auto-newline' corrected. |
| 166 | ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation |
| 167 | ;;; like $hash{. |
| 168 | |
| 169 | ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de): |
| 170 | ;;; - use `next-command-event', if `next-command-events' does not exist |
| 171 | ;;; - use `find-face' as def. of `is-face' |
| 172 | ;;; - corrected def. of `x-color-defined-p' |
| 173 | ;;; - added const defs for font-lock-comment-face, |
| 174 | ;;; font-lock-keyword-face and font-lock-function-name-face |
| 175 | ;;; - added def. of font-lock-variable-name-face |
| 176 | ;;; - added (require 'easymenu) inside an `eval-when-compile' |
| 177 | ;;; - replaced 4-argument `substitute-key-definition' with ordinary |
| 178 | ;;; `define-key's |
| 179 | ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'. |
| 180 | ;;; Todo (at least): |
| 181 | ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz) |
| 182 | ;;; for portable code? |
| 183 | ;;; - should `cperl-mode' do a |
| 184 | ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu)) |
| 185 | ;;; or should this be left to the user's `cperl-mode-hook'? |
| 186 | |
| 187 | ;;; Some bugs introduced by the above fix corrected (IZ ;-). |
| 188 | ;;; Some bugs under XEmacs introduced by the correction corrected. |
| 189 | |
| 190 | ;;; Some more can remain since there are two many different variants. |
| 191 | ;;; Please feedback! |
| 192 | |
| 193 | ;;; We do not support fontification of arrays and hashes under |
| 194 | ;;; obsolete font-lock any more. Upgrade. |
| 195 | |
| 196 | ;;;; after 1.8 Minor bug with parentheses. |
| 197 | ;;;; after 1.9 Improvements from Joe Marzot. |
| 198 | ;;;; after 1.10 |
| 199 | ;;; Does not need easymenu to compile under XEmacs. |
| 200 | ;;; `vc-insert-headers' should work better. |
| 201 | ;;; Should work with 19.29 and 19.12. |
| 202 | ;;; Small improvements to fontification. |
| 203 | ;;; Expansion of keywords does not depend on C-? being backspace. |
| 204 | |
| 205 | ;;; after 1.10+ |
| 206 | ;;; 19.29 and 19.12 supported. |
| 207 | ;;; `cperl-font-lock-enhanced' deprecated. Use font-lock-extra.el. |
| 208 | ;;; Support for font-lock-extra.el. |
| 209 | |
| 210 | ;;;; After 1.11: |
| 211 | ;;; Tools submenu. |
| 212 | ;;; Support for perl5-info. |
| 213 | ;;; `imenu-go-find-at-position' in Tools requires imenu-go.el (see hints above) |
| 214 | ;;; Imenu entries do not work with stock imenu.el. Patch sent to maintainers. |
| 215 | ;;; Fontifies `require a if b;', __DATA__. |
| 216 | ;;; Arglist for auto-fill-mode was incorrect. |
| 217 | |
| 218 | ;;;; After 1.12: |
| 219 | ;;; `cperl-lineup-step' and `cperl-lineup' added: lineup constructions |
| 220 | ;;; vertically. |
| 221 | ;;; `cperl-do-auto-fill' updated for 19.29 style. |
| 222 | ;;; `cperl-info-on-command' now has a default. |
| 223 | ;;; Workaround for broken C-h on XEmacs. |
| 224 | ;;; VC strings escaped. |
| 225 | ;;; C-h f now may prompt for function name instead of going on, |
| 226 | ;;; controlled by `cperl-info-on-command-no-prompt'. |
| 227 | |
| 228 | ;;;; After 1.13: |
| 229 | ;;; Msb buffer list includes perl files |
| 230 | ;;; Indent-for-comment uses indent-to |
| 231 | ;;; Can write tag files using etags. |
| 232 | |

| 524 | Expression and list commands understand all C brackets. |
| 525 | Tab indents for Perl code. |
| 526 | Paragraphs are separated by blank lines only. |
| 527 | Delete converts tabs to spaces as it moves back. |
| 528 | |
| 529 | Various characters in Perl almost always come in pairs: {}, (), [], |
| 530 | sometimes <>. When the user types the first, she gets the second as |
| 531 | well, with optional special formatting done on {}. (Disabled by |
| 532 | default.) You can always quote (with \\[quoted-insert]) the left |
| 533 | \"paren\" to avoid the expansion. The processing of < is special, |
| 534 | since most the time you mean \"less\". Cperl mode tries to guess |
| 535 | whether you want to type pair <>, and inserts is if it |
| 536 | appropriate. You can set `cperl-electric-parens' to the string that |
| 537 | contains the parenths from the above list you want to be electrical. |
| 538 | |
| 539 | CPerl mode provides expansion of the Perl control constructs: |
| 540 | if, else, elsif, unless, while, until, for, and foreach. |
| 541 | =========(Disabled by default, see `cperl-electric-keywords'.) |
| 542 | The user types the keyword immediately followed by a space, which causes |
| 543 | the construct to be expanded, and the user is positioned where she is most |
| 544 | likely to want to be. |
| 545 | eg. when the user types a space following \"if\" the following appears in |
| 546 | the buffer: |
| 547 | if () { or if () |
| 548 | } { |
| 549 | } |
| 550 | and the cursor is between the parentheses. The user can then type some |
| 551 | boolean expression within the parens. Having done that, typing |
| 552 | \\[cperl-linefeed] places you, appropriately indented on a new line |
| 553 | between the braces. If CPerl decides that you want to insert |
| 554 | \"English\" style construct like |
| 555 | bite if angry; |
| 556 | it will not do any expansion. See also help on variable |
| 557 | `cperl-extra-newline-before-brace'. |
| 558 | |
| 559 | \\[cperl-linefeed] is a convinience replacement for typing carriage |
| 560 | return. It places you in the next line with proper indentation, or if |
| 561 | you type it inside the inline block of control construct, like |
| 562 | foreach (@lines) {print; print} |
| 563 | and you are on a boundary of a statement inside braces, it will |
| 564 | transform the construct into a multiline and will place you into an |
| 565 | apporpriately indented blank line. If you need a usual |
| 566 | `newline-and-indent' behaviour, it is on \\[newline-and-indent], |
| 567 | see documentation on `cperl-electric-linefeed'. |
| 568 | |
| 569 | \\{cperl-mode-map} |
| 570 | |
| 571 | Setting the variable `cperl-font-lock' to t switches on |
| 572 | font-lock-mode, `cperl-electric-lbrace-space' to t switches on |
| 573 | electric space between $ and {, `cperl-electric-parens' is the string |
| 574 | that contains parentheses that should be electric in CPerl, setting |
| 575 | `cperl-electric-keywords' enables electric expansion of control |
| 576 | structures in CPerl. `cperl-electric-linefeed' governs which one of |
| 577 | two linefeed behavior is preferable. You can enable all these options |
| 578 | simultaneously (recommended mode of use) by setting `cperl-hairy' to |
| 579 | t. In this case you can switch separate options off by setting them |
| 580 | to `null'. |
| 581 | |
| 582 | If your site has perl5 documentation in info format, you can use commands |
| 583 | \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it. |
| 584 | These keys run commands `cperl-info-on-current-command' and |
| 585 | `cperl-info-on-command', which one is which is controlled by variable |
| 586 | `cperl-info-on-command-no-prompt' (in turn affected by `cperl-hairy'). |
| 587 | |
| 588 | Variables controlling indentation style: |
| 589 | `cperl-tab-always-indent' |
| 590 | Non-nil means TAB in CPerl mode should always reindent the current line, |
| 591 | regardless of where in the line point is when the TAB command is used. |
| 592 | `cperl-auto-newline' |
| 593 | Non-nil means automatically newline before and after braces, |
| 594 | and after colons and semicolons, inserted in Perl code. |
| 595 | `cperl-indent-level' |
| 596 | Indentation of Perl statements within surrounding block. |
| 597 | The surrounding block's indentation is the indentation |
| 598 | of the line on which the open-brace appears. |
| 599 | `cperl-continued-statement-offset' |
| 600 | Extra indentation given to a substatement, such as the |
| 601 | then-clause of an if, or body of a while, or just a statement continuation. |
| 602 | `cperl-continued-brace-offset' |
| 603 | Extra indentation given to a brace that starts a substatement. |
| 604 | This is in addition to `cperl-continued-statement-offset'. |
| 605 | `cperl-brace-offset' |
| 606 | Extra indentation for line if it starts with an open brace. |
| 607 | `cperl-brace-imaginary-offset' |
| 608 | An open brace following other text is treated as if it the line started |
| 609 | this far to the right of the actual line indentation. |
| 610 | `cperl-label-offset' |
| 611 | Extra indentation for line that is a label. |
| 612 | `cperl-min-label-indent' |
| 613 | Minimal indentation for line that is a label. |
| 614 | |
| 615 | Settings for K&R and BSD indentation styles are |
| 616 | `cperl-indent-level' 5 8 |
| 617 | `cperl-continued-statement-offset' 5 8 |
| 618 | `cperl-brace-offset' -5 -8 |
| 619 | `cperl-label-offset' -5 -8 |
| 620 | |
| 621 | If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'. |
| 622 | |
