34 ;;; To use this mode put the following into your .emacs file:
|
|
35
|
|
36 ;; (autoload 'perl-mode "cperl-mode" "alternate mode for editing Perl programs" t)
|
|
37
|
|
38 ;;; You can either fine-tune the bells and whistles of this mode or
|
|
39 ;;; bulk enable them by putting
|
|
40
|
|
41 ;; (setq cperl-hairy t)
|
|
42
|
|
43 ;;; in your .emacs file. (Emacs rulers do not consider it politically
|
|
44 ;;; correct to make whistles enabled by default.)
|
|
45
|
|
46 ;;; Additional useful commands to put into your .emacs file:
|
|
47
|
|
48 ;; (setq auto-mode-alist
|
|
49 ;; (append '(("\\.[pP][Llm]$" . perl-mode)) auto-mode-alist ))
|
|
50 ;; (setq interpreter-mode-alist (append interpreter-mode-alist
|
|
51 ;; '(("miniperl" . perl-mode))))
|
|
52
|
|
53 ;;; The mode information (on C-h m) provides customization help.
|
|
54 ;;; If you use font-lock feature of this mode, it is advisable to use
|
|
55 ;;; eather lazy-lock-mode or fast-lock-mode (available on ELisp
|
|
56 ;;; archive in files lazy-lock.el and fast-lock.el). I prefer lazy-lock.
|
|
57
|
|
58 ;;; Faces used now: three faces for first-class and second-class keywords
|
|
59 ;;; and control flow words, one for each: comments, string, labels,
|
|
60 ;;; functions definitions and packages, arrays, hashes, and variable
|
|
61 ;;; definitions. If you do not see all these faces, your font-lock does
|
|
62 ;;; not define them, so you need to define them manually. Maybe you have
|
|
63 ;;; an obsolete font-lock from 19.28 or earlier. Upgrade.
|
|
64
|
|
65 ;;; If you have grayscale monitor, and do not have the variable
|
|
66 ;;; font-lock-display-type bound to 'grayscale, insert
|
|
67
|
|
68 ;;; (setq font-lock-display-type 'grayscale)
|
|
69
|
|
70 ;;; to your .emacs file.
|
|
71
|
|
72 ;;;; This mode supports font-lock, imenu and mode-compile. In the
|
|
73 ;;;; hairy version font-lock is on, but you should activate imenu
|
|
74 ;;;; yourself (note that mode-compile is not standard yet). Well, you
|
|
75 ;;;; can use imenu from keyboard anyway (M-x imenu), but it is better
|
|
76 ;;;; to bind it like that:
|
|
77
|
|
78 ;; (define-key global-map [M-S-down-mouse-3] 'imenu)
|
|
79
|
|
80 ;;; In fact the version of font-lock that this version supports can be
|
|
81 ;;; much newer than the version you actually have. This means that a
|
|
82 ;;; lot of faces can be set up, but are not visible on your screen
|
|
83 ;;; since the coloring rules for this faces are not defined.
|
|
84
|
|
85 ;;; Updates: ========================================
|
|
86
|
|
87 ;;; Made less hairy by default: parentheses not electric,
|
|
88 ;;; linefeed not magic. Bug with abbrev-mode corrected.
|
|
89
|
|
90 ;;;; After 1.4:
|
|
91 ;;; Better indentation:
|
|
92 ;;; subs inside braces should work now,
|
|
93 ;;; Toplevel braces obey customization.
|
|
94 ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment
|
|
95 ;;; moves cursor to a correct place.
|
|
96 ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-(
|
|
97 ;;; (50 secs on DB::DB (sub of 430 lines), 486/66)
|
|
98 ;;; Minor documentation fixes.
|
|
99 ;;; Imenu understands packages as prefixes (including nested).
|
|
100 ;;; Hairy options can be switched off one-by-one by setting to null.
|
|
101 ;;; Names of functions and variables changed to conform to `cperl-' style.
|
|
102
|
|
103 ;;;; After 1.5:
|
|
104 ;;; Some bugs with indentation of labels (and embedded subs) corrected.
|
|
105 ;;; `cperl-indent-region' done (slow :-()).
|
|
106 ;;; `cperl-fill-paragraph' done.
|
|
107 ;;; Better package support for `imenu'.
|
|
108 ;;; Progress indicator for indentation (with `imenu' loaded).
|
|
109 ;;; `Cperl-set' was busted, now setting the individual hairy option
|
|
110 ;;; should be better.
|
|
111
|
|
112 ;;;; After 1.6:
|
|
113 ;;; `cperl-set-style' done.
|
|
114 ;;; `cperl-check-syntax' done.
|
|
115 ;;; Menu done.
|
|
116 ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'.
|
|
117 ;;; Bugs with `cperl-auto-newline' corrected.
|
|
118 ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation
|
|
119 ;;; like $hash{.
|
|
120
|
|
121 ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de):
|
|
122 ;;; - use `next-command-event', if `next-command-events' does not exist
|
|
123 ;;; - use `find-face' as def. of `is-face'
|
|
124 ;;; - corrected def. of `x-color-defined-p'
|
|
125 ;;; - added const defs for font-lock-comment-face,
|
|
126 ;;; font-lock-keyword-face and font-lock-function-name-face
|
|
127 ;;; - added def. of font-lock-variable-name-face
|
|
128 ;;; - added (require 'easymenu) inside an `eval-when-compile'
|
|
129 ;;; - replaced 4-argument `substitute-key-definition' with ordinary
|
|
130 ;;; `define-key's
|
|
131 ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'.
|
|
132 ;;; Todo (at least):
|
|
133 ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz)
|
|
134 ;;; for portable code?
|
|
135 ;;; - should `cperl-mode' do a
|
|
136 ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu))
|
|
137 ;;; or should this be left to the user's `cperl-mode-hook'?
|
|
138
|
|
139 ;;; Some bugs introduced by the above fix corrected (IZ ;-).
|
|
140 ;;; Some bugs under XEmacs introduced by the correction corrected.
|
|
141
|
|
142 ;;; Some more can remain since there are two many different variants.
|
|
143 ;;; Please feedback!
|
|
144

145 ;;; We do not support fontification of arrays and hashes under

146 ;;; obsolete font-lock any more. Upgrade.

166 ;;; Imenu entries do not work with stock imenu.el. Patch sent to maintainers.
|
|
167 ;;; Fontifies `require a if b;', __DATA__.
|
|
168 ;;; Arglist for auto-fill-mode was incorrect.
|
|
169
|

170 ;;;; After 1.12:
|

171 ;;; `cperl-lineup-step' and `cperl-lineup' added: lineup constructions
|

172 ;;; vertically.
|
|
173 ;;; `cperl-do-auto-fill' updated for 19.29 style.
|
|
174 ;;; `cperl-info-on-command' now has a default.
|
|
175 ;;; Workaround for broken C-h on XEmacs.
|
|
176 ;;; VC strings escaped.
|
|
177 ;;; C-h f now may prompt for function name instead of going on,
|

178 ;;; controlled by `cperl-info-on-command-no-prompt'.

179

180 ;;;; After 1.13:

|
|
422
|
|
423 CPerl mode tries to corrects some Emacs misunderstandings, however,
|
|
424 for effeciency reasons the degree of correction is different for
|
|
425 different operations. The partially corrected problems are: POD
|
|
426 sections, here-documents, regexps. The operations are: highlighting,
|
|
427 indentation, electric keywords, electric braces.
|
|
428
|
|
429 This may be confusing, since the regexp s#//#/#\; may be highlighted
|
|
430 as a comment, but it will recognized as a regexp by the indentation
|
|
431 code. Or the opposite case, when a pod section is highlighted, but
|
|
432 breaks the indentation of the following code.
|
|
433
|
|
434 The main trick (to make $ a \"backslash\") makes constructions like
|
|
435 ${aaa} look like unbalanced braces. The only trick I can think out is
|
|
436 to insert it as $ {aaa} (legal in perl5, not in perl4).
|
|
437
|
|
438 Similar problems arise in regexps, when /(\\s|$)/ should be rewritten
|
|
439 as /($|\\s)/. Note that such a transpositinon is not always possible
|
|
440 :-(. " )

445 Most the time, if you write your own code, you may find an equivalent
|
|
446 \(and almost as readable) expression.
|
|
447
|
|
448 Try to help it: add comments with embedded quotes to fix CPerl
|
|
449 misunderstandings about the end of quotation:
|
|
450
|
|
451 $a='500$'; # ';
|
|
452
|
|
453 You won't need it too often. The reason: $ \"quotes\" the following
|
|
454 character (this saves a life a lot of times in CPerl), thus due to
|
|
455 Emacs parsing rules it does not consider tick after the dollar as a
|
|
456 closing one, but as a usual character.
|
|
457
|
|
458 Now the indentation code is pretty wise. The only drawback is that it
|
|
459 relies on Emacs parsing to find matching parentheses. And Emacs
|
|
460 *cannot* match parentheses in Perl 100% correctly. So
|
|
461 1 if s#//#/#;
|
|
462 will not break indentation, but
|
|
463 1 if ( s#//#/# );
|
|
464 will.
|
|
465
|
|
466 If you still get wrong indentation in situation that you think the
|
|
467 code should be able to parse, try:
|
|
468
|
|
469 a) Check what Emacs thinks about balance of your parentheses.
|
|
470 b) Supply the code to me (IZ).
|
|
471
|
|
472 Pods are treated _very_ rudimentally. Here-documents are not treated
|
|
473 at all (except highlighting and inhibiting indentation). (This may
|
|
474 change some time. RMS approved making syntax lookup recognize text
|
|
475 attributes, but volonteers are needed to change Emacs C code.)
|
|
476
|
|
477 To speed up coloring the following compromises exist:
|
|
478 a) sub in $mypackage::sub may be highlighted.
|
|
479 b) -z in [a-z] may be highlighted.
|
|
480 c) if your regexp contains a keyword (like \"s\"), it may be highlighted.

713 "Major mode for editing Perl code.
|
|
714 Expression and list commands understand all C brackets.
|
|
715 Tab indents for Perl code.
|
|
716 Paragraphs are separated by blank lines only.
|
|
717 Delete converts tabs to spaces as it moves back.
|
|
718
|
|
719 Various characters in Perl almost always come in pairs: {}, (), [],
|
|
720 sometimes <>. When the user types the first, she gets the second as
|
|
721 well, with optional special formatting done on {}. (Disabled by
|
|
722 default.) You can always quote (with \\[quoted-insert]) the left
|
|
723 \"paren\" to avoid the expansion. The processing of < is special,
|
|
724 since most the time you mean \"less\". Cperl mode tries to guess
|
|
725 whether you want to type pair <>, and inserts is if it
|
|
726 appropriate. You can set `cperl-electric-parens-string' to the string that
|
|
727 contains the parenths from the above list you want to be electrical.
|
|
728 Electricity of parenths is controlled by `cperl-electric-parens'.
|
|
729 You may also set `cperl-electric-parens-mark' to have electric parens
|
|
730 look for active mark and \"embrace\" a region if possible.'
|
|
731
|
|
732 CPerl mode provides expansion of the Perl control constructs:
|
|
733 if, else, elsif, unless, while, until, for, and foreach.
|
|
734 =========(Disabled by default, see `cperl-electric-keywords'.)
|
|
735 The user types the keyword immediately followed by a space, which causes
|
|
736 the construct to be expanded, and the user is positioned where she is most
|
|
737 likely to want to be.
|
|
738 eg. when the user types a space following \"if\" the following appears in
|
|
739 the buffer:
|
|
740 if () { or if ()
|
|
741 } {
|
|
742 }
|
|
743 and the cursor is between the parentheses. The user can then type some
|
|
744 boolean expression within the parens. Having done that, typing
|
|
745 \\[cperl-linefeed] places you, appropriately indented on a new line
|
|
746 between the braces. If CPerl decides that you want to insert
|
|
747 \"English\" style construct like
|
|
748 bite if angry;
|
|
749 it will not do any expansion. See also help on variable
|
|
750 `cperl-extra-newline-before-brace'.
|
|
751
|
|
752 \\[cperl-linefeed] is a convinience replacement for typing carriage
|
|
753 return. It places you in the next line with proper indentation, or if
|
|
754 you type it inside the inline block of control construct, like
|
|
755 foreach (@lines) {print; print}
|
|
756 and you are on a boundary of a statement inside braces, it will
|
|
757 transform the construct into a multiline and will place you into an
|
|
758 apporpriately indented blank line. If you need a usual
|
|
759 `newline-and-indent' behaviour, it is on \\[newline-and-indent],
|
|
760 see documentation on `cperl-electric-linefeed'.
|
|
761
|
|
762 \\{cperl-mode-map}
|
|
763
|
|
764 Setting the variable `cperl-font-lock' to t switches on
|
|
765 font-lock-mode, `cperl-electric-lbrace-space' to t switches on
|
|
766 electric space between $ and {, `cperl-electric-parens-string' is the
|
|
767 string that contains parentheses that should be electric in CPerl (see
|
|
768 also `cperl-electric-parens-mark' and `cperl-electric-parens'),
|
|
769 setting `cperl-electric-keywords' enables electric expansion of
|
|
770 control structures in CPerl. `cperl-electric-linefeed' governs which
|
|
771 one of two linefeed behavior is preferable. You can enable all these
|
|
772 options simultaneously (recommended mode of use) by setting
|
|
773 `cperl-hairy' to t. In this case you can switch separate options off
|
|
774 by setting them to `null'. Note that one may undo the extra whitespace
|
|
775 inserted by semis and braces in `auto-newline'-mode by consequent
|
|
776 \\[cperl-electric-backspace].
|
|
777
|
|
778 If your site has perl5 documentation in info format, you can use commands
|
|
779 \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it.
|
|
780 These keys run commands `cperl-info-on-current-command' and
|
|
781 `cperl-info-on-command', which one is which is controlled by variable
|
|
782 `cperl-info-on-command-no-prompt' (in turn affected by `cperl-hairy').
|
|
783
|
|
784 Variables `cperl-pod-here-scan', `cperl-pod-here-fontify',
|
|
785 `cperl-pod-face', `cperl-pod-head-face' control processing of pod and
|
|
786 here-docs sections. In a future version results of scan may be used
|
|
787 for indentation too, currently they are used for highlighting only.
|
|
788
|
|
789 Variables controlling indentation style:
|
|
790 `cperl-tab-always-indent'
|
|
791 Non-nil means TAB in CPerl mode should always reindent the current line,
|
|
792 regardless of where in the line point is when the TAB command is used.
|
|
793 `cperl-auto-newline'
|
|
794 Non-nil means automatically newline before and after braces,
|
|
795 and after colons and semicolons, inserted in Perl code. The following
|
|
796 \\[cperl-electric-backspace] will remove the inserted whitespace.
|
|
797 Insertion after colons requires both this variable and
|
|
798 `cperl-auto-newline-after-colon' set.
|
|
799 `cperl-auto-newline-after-colon'
|
|
800 Non-nil means automatically newline even after colons.
|
|
801 Subject to `cperl-auto-newline' setting.
|
|
802 `cperl-indent-level'
|
|
803 Indentation of Perl statements within surrounding block.
|
|
804 The surrounding block's indentation is the indentation
|
|
805 of the line on which the open-brace appears.
|
|
806 `cperl-continued-statement-offset'
|
|
807 Extra indentation given to a substatement, such as the
|
|
808 then-clause of an if, or body of a while, or just a statement continuation.
|
|
809 `cperl-continued-brace-offset'
|
|
810 Extra indentation given to a brace that starts a substatement.
|
|
811 This is in addition to `cperl-continued-statement-offset'.
|
|
812 `cperl-brace-offset'
|
|
813 Extra indentation for line if it starts with an open brace.
|
|
814 `cperl-brace-imaginary-offset'
|
|
815 An open brace following other text is treated as if it the line started
|
|
816 this far to the right of the actual line indentation.
|
|
817 `cperl-label-offset'
|
|
818 Extra indentation for line that is a label.
|
|
819 `cperl-min-label-indent'
|
|
820 Minimal indentation for line that is a label.
|
|
821
|
|
822 Settings for K&R and BSD indentation styles are
|
|
823 `cperl-indent-level' 5 8
|
|
824 `cperl-continued-statement-offset' 5 8
|
|
825 `cperl-brace-offset' -5 -8
|
|
826 `cperl-label-offset' -5 -8
|
|
827
|
|
828 If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'.
|
|
829
|
|
830 Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook'
