75 ;;;; This mode supports font-lock, imenu and mode-compile. In the
|
|
|
76 ;;;; hairy version font-lock is on, but you should activate imenu
|
|
|
77 ;;;; yourself (note that mode-compile is not standard yet). Well, you
|
|
|
78 ;;;; can use imenu from keyboard anyway (M-x imenu), but it is better
|
|
|
79 ;;;; to bind it like that:
|
|
|
80
|
|
|
81 ;; (define-key global-map [M-S-down-mouse-3] 'imenu)
|
|
|
82
|
|
|
83 ;;; In fact the version of font-lock that this version supports can be
|
|
|
84 ;;; much newer than the version you actually have. This means that a
|
|
|
85 ;;; lot of faces can be set up, but are not visible on your screen
|
|
|
86 ;;; since the coloring rules for this faces are not defined.
|
|
|
87
|
|
|
88 ;;; Updates: ========================================
|
|
|
89
|
|
|
90 ;;; Made less hairy by default: parentheses not electric,
|
|
|
91 ;;; linefeed not magic. Bug with abbrev-mode corrected.
|
|
|
92
|
|
|
93 ;;;; After 1.4:
|
|
|
94 ;;; Better indentation:
|
|
|
95 ;;; subs inside braces should work now,
|
|
|
96 ;;; Toplevel braces obey customization.
|
|
|
97 ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment
|
|
|
98 ;;; moves cursor to a correct place.
|
|
|
99 ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-(
|
|
|
100 ;;; (50 secs on DB::DB (sub of 430 lines), 486/66)
|
|
|
101 ;;; Minor documentation fixes.
|
|
|
102 ;;; Imenu understands packages as prefixes (including nested).
|
|
|
103 ;;; Hairy options can be switched off one-by-one by setting to null.
|
|
|
104 ;;; Names of functions and variables changed to conform to `cperl-' style.
|
|
|
105
|
|
|
106 ;;;; After 1.5:
|
|
|
107 ;;; Some bugs with indentation of labels (and embedded subs) corrected.
|
|
|
108 ;;; `cperl-indent-region' done (slow :-()).
|
|
|
109 ;;; `cperl-fill-paragraph' done.
|
|
|
110 ;;; Better package support for `imenu'.
|
|
|
111 ;;; Progress indicator for indentation (with `imenu' loaded).
|
|
|
112 ;;; `Cperl-set' was busted, now setting the individual hairy option
|
|
|
113 ;;; should be better.
|
|
|
114
|
|
|
115 ;;;; After 1.6:
|
|
|
116 ;;; `cperl-set-style' done.
|
|
|
117 ;;; `cperl-check-syntax' done.
|
|
|
118 ;;; Menu done.
|
|
|
119 ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'.
|
|
|
120 ;;; Bugs with `cperl-auto-newline' corrected.
|
|
|
121 ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation
|
|
|
122 ;;; like $hash{.
|
|
|
123
|
|
|
124 ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de):
|
|
|
125 ;;; - use `next-command-event', if `next-command-events' does not exist
|
|
|
126 ;;; - use `find-face' as def. of `is-face'
|
|
|
127 ;;; - corrected def. of `x-color-defined-p'
|
|
|
128 ;;; - added const defs for font-lock-comment-face,
|
|
|
129 ;;; font-lock-keyword-face and font-lock-function-name-face
|
|
|
130 ;;; - added def. of font-lock-variable-name-face
|
|
|
131 ;;; - added (require 'easymenu) inside an `eval-when-compile'
|
|
|
132 ;;; - replaced 4-argument `substitute-key-definition' with ordinary
|
|
|
133 ;;; `define-key's
|
|
|
134 ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'.
|
|
|
135 ;;; Todo (at least):
|
|
|
136 ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz)
|
|
|
137 ;;; for portable code?
|
|
|
138 ;;; - should `cperl-mode' do a
|
|
|
139 ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu))
|
|
|
140 ;;; or should this be left to the user's `cperl-mode-hook'?
|
|
|
141
|
|
|
142 ;;; Some bugs introduced by the above fix corrected (IZ ;-).
|
|
|
143 ;;; Some bugs under XEmacs introduced by the correction corrected.
|
|
|
144
|
|

172
|
|

173 ;;;; After 1.12:

510 different operations. The partially corrected problems are: POD

512 indentation, electric keywords, electric braces.

516 code. Or the opposite case, when a pod section is highlighted, but

539 character (this saves a life a lot of times in CPerl), thus due to
|
|

540 Emacs parsing rules it does not consider tick after the dollar as a

541 closing one, but as a usual character.
|
|
|
542
|
|
|
543 Now the indentation code is pretty wise. The only drawback is that it
|
|
|
544 relies on Emacs parsing to find matching parentheses. And Emacs
|
|
|
545 *cannot* match parentheses in Perl 100% correctly. So
|
|
|
546 1 if s#//#/#;
|
|
|
547 will not break indentation, but

548 1 if ( s#//#/# );

|
|
|
553
|
|
|
554 a) Check what Emacs thinks about balance of your parentheses.
|
|
|
555 b) Supply the code to me (IZ).
|
|
|
556
|
|
|
557 Pods are treated _very_ rudimentally. Here-documents are not treated
|
|
|
558 at all (except highlighting and inhibiting indentation). (This may
|
|
|
559 change some time. RMS approved making syntax lookup recognize text

562 To speed up coloring the following compromises exist:

831 Paragraphs are separated by blank lines only.
|
|
|
832 Delete converts tabs to spaces as it moves back.
|
|
|
833
|
|
|
834 Various characters in Perl almost always come in pairs: {}, (), [],
|
|
|
835 sometimes <>. When the user types the first, she gets the second as
|
|
|
836 well, with optional special formatting done on {}. (Disabled by
|
|
|
837 default.) You can always quote (with \\[quoted-insert]) the left
|
|
|
838 \"paren\" to avoid the expansion. The processing of < is special,
|
|
|
839 since most the time you mean \"less\". Cperl mode tries to guess
|
|
|
840 whether you want to type pair <>, and inserts is if it
|
|
|
841 appropriate. You can set `cperl-electric-parens-string' to the string that
|
|
|
842 contains the parenths from the above list you want to be electrical.
|
|
|
843 Electricity of parenths is controlled by `cperl-electric-parens'.
|
|
|
844 You may also set `cperl-electric-parens-mark' to have electric parens
|
|
|
845 look for active mark and \"embrace\" a region if possible.'
|
|
|
846
|
|
|
847 CPerl mode provides expansion of the Perl control constructs:
|
|
|
848 if, else, elsif, unless, while, until, for, and foreach.
|
|
|
849 =========(Disabled by default, see `cperl-electric-keywords'.)
|
|
|
850 The user types the keyword immediately followed by a space, which causes
|
|
|
851 the construct to be expanded, and the user is positioned where she is most
|
|
|
852 likely to want to be.
|
|
|
853 eg. when the user types a space following \"if\" the following appears in
|
|
|
854 the buffer:
|
|
|
855 if () { or if ()
|
|
|
856 } {
|
|
|
857 }
|
|
|
858 and the cursor is between the parentheses. The user can then type some
|
|
|
859 boolean expression within the parens. Having done that, typing
|
|
|
860 \\[cperl-linefeed] places you, appropriately indented on a new line
|
|
|
861 between the braces. If CPerl decides that you want to insert
|
|
|
862 \"English\" style construct like
|
|
|
863 bite if angry;
|
|
|
864 it will not do any expansion. See also help on variable
|
|
|
865 `cperl-extra-newline-before-brace'.
|
|
|
866
|
|
4
|
867 \\[cperl-linefeed] is a convenience replacement for typing carriage
|
|
0
|
868 return. It places you in the next line with proper indentation, or if
|
|
|
869 you type it inside the inline block of control construct, like
|
|
|
870 foreach (@lines) {print; print}
|
|
|
871 and you are on a boundary of a statement inside braces, it will
|
|
|
872 transform the construct into a multiline and will place you into an
|
|
4
|
873 appropriately indented blank line. If you need a usual
|
|
0
|
874 `newline-and-indent' behaviour, it is on \\[newline-and-indent],
|
|
|
875 see documentation on `cperl-electric-linefeed'.

|
|
|
883 also `cperl-electric-parens-mark' and `cperl-electric-parens'),
|
|
|
884 setting `cperl-electric-keywords' enables electric expansion of
|
|
|
885 control structures in CPerl. `cperl-electric-linefeed' governs which
|
|
|
886 one of two linefeed behavior is preferable. You can enable all these
|
|
|
887 options simultaneously (recommended mode of use) by setting
|
|
|
888 `cperl-hairy' to t. In this case you can switch separate options off
|
|
|
889 by setting them to `null'. Note that one may undo the extra whitespace
|
|
|
890 inserted by semis and braces in `auto-newline'-mode by consequent
|

891 \\[cperl-electric-backspace].

893 If your site has perl5 documentation in info format, you can use commands
|
|
|
894 \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it.
|
|
|
895 These keys run commands `cperl-info-on-current-command' and
|
|
|
896 `cperl-info-on-command', which one is which is controlled by variable

905 is nil. It is also possible to switch this on/off from the

|
908 Variables `cperl-pod-here-scan', `cperl-pod-here-fontify',
|
|
|
909 `cperl-pod-face', `cperl-pod-head-face' control processing of pod and
|
|
|
910 here-docs sections. In a future version results of scan may be used
|
|
|
911 for indentation too, currently they are used for highlighting only.
|
|
|
912
|
|
|
913 Variables controlling indentation style:
|
|
|
914 `cperl-tab-always-indent'
|
|
|
915 Non-nil means TAB in CPerl mode should always reindent the current line,
|
|
|
916 regardless of where in the line point is when the TAB command is used.
|
|
|
917 `cperl-auto-newline'
|
|
|
918 Non-nil means automatically newline before and after braces,
|
|
|
919 and after colons and semicolons, inserted in Perl code. The following
|
|
|
920 \\[cperl-electric-backspace] will remove the inserted whitespace.
|
|
|
921 Insertion after colons requires both this variable and
|
|
|
922 `cperl-auto-newline-after-colon' set.
|
|
|
923 `cperl-auto-newline-after-colon'
|
|
|
924 Non-nil means automatically newline even after colons.
|
|
|
925 Subject to `cperl-auto-newline' setting.
|
|
|
926 `cperl-indent-level'
|
|
|
927 Indentation of Perl statements within surrounding block.
|
|
|
928 The surrounding block's indentation is the indentation
|
|
|
929 of the line on which the open-brace appears.
|
|
|
930 `cperl-continued-statement-offset'
|
|
|
931 Extra indentation given to a substatement, such as the
|
|
|
932 then-clause of an if, or body of a while, or just a statement continuation.
|
|
|
933 `cperl-continued-brace-offset'
|
|
|
934 Extra indentation given to a brace that starts a substatement.
|
|
|
935 This is in addition to `cperl-continued-statement-offset'.
|
|
|
936 `cperl-brace-offset'
|
|
|
937 Extra indentation for line if it starts with an open brace.
|
|
|
938 `cperl-brace-imaginary-offset'
|
|
|
939 An open brace following other text is treated as if it the line started
|
|
|
940 this far to the right of the actual line indentation.
|
|
|
941 `cperl-label-offset'
|
|
|
942 Extra indentation for line that is a label.
|
|
|
943 `cperl-min-label-indent'
|
|
|
944 Minimal indentation for line that is a label.
|
|
|
945
|
|
|
946 Settings for K&R and BSD indentation styles are
|
|
|
947 `cperl-indent-level' 5 8
|
|
|
948 `cperl-continued-statement-offset' 5 8
|
|
|
949 `cperl-brace-offset' -5 -8
|
|
|
950 `cperl-label-offset' -5 -8
|
|
|
951
|
|
|
952 If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'.
|
|
|
953
|
|
|
954 Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook'
