81 ;;;; This mode supports font-lock, imenu and mode-compile. In the
|
|
|
82 ;;;; hairy version font-lock is on, but you should activate imenu
|
|
|
83 ;;;; yourself (note that mode-compile is not standard yet). Well, you
|
|
|
84 ;;;; can use imenu from keyboard anyway (M-x imenu), but it is better
|
|
|
85 ;;;; to bind it like that:
|
|
|
86

|
|
87 ;; (define-key global-map [M-S-down-mouse-3] 'imenu)

|
|
88
|

89 ;;; In fact the version of font-lock that this version supports can be

93
|
|
|
94 ;;; Updates: ========================================
|
|
|
95
|
|
|
96 ;;; Made less hairy by default: parentheses not electric,
|
|
|
97 ;;; linefeed not magic. Bug with abbrev-mode corrected.
|
|
|
98
|
|
|
99 ;;;; After 1.4:
|
|
|
100 ;;; Better indentation:
|
|
|
101 ;;; subs inside braces should work now,
|
|
|
102 ;;; Toplevel braces obey customization.
|
|

105 ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-(
|

106 ;;; (50 secs on DB::DB (sub of 430 lines), 486/66)
|
|
|
107 ;;; Minor documentation fixes.
|
|
|
108 ;;; Imenu understands packages as prefixes (including nested).
|
|
|
109 ;;; Hairy options can be switched off one-by-one by setting to null.
|
|
|
110 ;;; Names of functions and variables changed to conform to `cperl-' style.

114 ;;; `cperl-indent-region' done (slow :-()).
|
|
|
115 ;;; `cperl-fill-paragraph' done.
|
|
|
116 ;;; Better package support for `imenu'.
|
|
|
117 ;;; Progress indicator for indentation (with `imenu' loaded).
|
|
|
118 ;;; `Cperl-set' was busted, now setting the individual hairy option
|
|
|
119 ;;; should be better.
|
|
|
120

|
|
|
124 ;;; Menu done.
|
|
|
125 ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'.

|
128 ;;; like $hash{.

|
132 ;;; - use `find-face' as def. of `is-face'
|
|
|
133 ;;; - corrected def. of `x-color-defined-p'
|
|
|
134 ;;; - added const defs for font-lock-comment-face,
|
|
|
135 ;;; font-lock-keyword-face and font-lock-function-name-face
|
|
|
136 ;;; - added def. of font-lock-variable-name-face
|
|
|
137 ;;; - added (require 'easymenu) inside an `eval-when-compile'
|
|
|
138 ;;; - replaced 4-argument `substitute-key-definition' with ordinary
|
|
|
139 ;;; `define-key's
|
|
|
140 ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'.
|
|
|
141 ;;; Todo (at least):
|
|
|
142 ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz)
|
|
|
143 ;;; for portable code?
|
|
|
144 ;;; - should `cperl-mode' do a
|
|
|
145 ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu))
|
|
|
146 ;;; or should this be left to the user's `cperl-mode-hook'?

|
147

|
148 ;;; Some bugs introduced by the above fix corrected (IZ ;-).

576

577 Now the indentation code is pretty wise. The only drawback is that it

|
578 relies on Emacs parsing to find matching parentheses. And Emacs
|
|
|
579 *cannot* match parentheses in Perl 100% correctly. So
|

|
580 1 if s#//#/#;

592 a) Check what Emacs thinks about balance of your parentheses.

595 Pods are treated _very_ rudimentally. Here-documents are not treated

870 Paragraphs are separated by blank lines only.
|

871 Delete converts tabs to spaces as it moves back.
|
|
|
872
|
|
|
873 Various characters in Perl almost always come in pairs: {}, (), [],
|
|
|
874 sometimes <>. When the user types the first, she gets the second as
|
|
|
875 well, with optional special formatting done on {}. (Disabled by
|
|
|
876 default.) You can always quote (with \\[quoted-insert]) the left
|
|
|
877 \"paren\" to avoid the expansion. The processing of < is special,
|
|
|
878 since most the time you mean \"less\". Cperl mode tries to guess
|
|
|
879 whether you want to type pair <>, and inserts is if it
|
|
|
880 appropriate. You can set `cperl-electric-parens-string' to the string that
|
|
|
881 contains the parenths from the above list you want to be electrical.
|
|
|
882 Electricity of parenths is controlled by `cperl-electric-parens'.
|
|
|
883 You may also set `cperl-electric-parens-mark' to have electric parens
|
|
|
884 look for active mark and \"embrace\" a region if possible.'
|
|
|
885
|
|
|
886 CPerl mode provides expansion of the Perl control constructs:
|
|
|
887 if, else, elsif, unless, while, until, for, and foreach.
|
|
|
888 =========(Disabled by default, see `cperl-electric-keywords'.)
|
|
|
889 The user types the keyword immediately followed by a space, which causes
|
|
|
890 the construct to be expanded, and the user is positioned where she is most
|
|
|
891 likely to want to be.
|
|
|
892 eg. when the user types a space following \"if\" the following appears in
|
|
|
893 the buffer:
|
|
|
894 if () { or if ()
|
|
|
895 } {
|
|
|
896 }
|
|
|
897 and the cursor is between the parentheses. The user can then type some
|
|
|
898 boolean expression within the parens. Having done that, typing
|
|
|
899 \\[cperl-linefeed] places you, appropriately indented on a new line
|
|
|
900 between the braces. If CPerl decides that you want to insert
|
|
|
901 \"English\" style construct like
|
|
|
902 bite if angry;
|
|

906 \\[cperl-linefeed] is a convenience replacement for typing carriage
|
|
0
|
907 return. It places you in the next line with proper indentation, or if
|
|
|
908 you type it inside the inline block of control construct, like
|
|
|
909 foreach (@lines) {print; print}
|
|
|
910 and you are on a boundary of a statement inside braces, it will
|
|
|
911 transform the construct into a multiline and will place you into an
|
|
4
|
912 appropriately indented blank line. If you need a usual
|
|
0
|
913 `newline-and-indent' behaviour, it is on \\[newline-and-indent],
|
|
|
914 see documentation on `cperl-electric-linefeed'.

918 Setting the variable `cperl-font-lock' to t switches on
|
|
|
919 font-lock-mode, `cperl-electric-lbrace-space' to t switches on
|
|
|
920 electric space between $ and {, `cperl-electric-parens-string' is the
|
|
|
921 string that contains parentheses that should be electric in CPerl (see
|
|
|
922 also `cperl-electric-parens-mark' and `cperl-electric-parens'),
|
|
|
923 setting `cperl-electric-keywords' enables electric expansion of
|
|
|
924 control structures in CPerl. `cperl-electric-linefeed' governs which
|
|
|
925 one of two linefeed behavior is preferable. You can enable all these
|
|
|
926 options simultaneously (recommended mode of use) by setting
|
|
|
927 `cperl-hairy' to t. In this case you can switch separate options off
|
|
|
928 by setting them to `null'. Note that one may undo the extra whitespace
|
|
|
929 inserted by semis and braces in `auto-newline'-mode by consequent
|
|
|
930 \\[cperl-electric-backspace].
|
|
|
931
|
|
|
932 If your site has perl5 documentation in info format, you can use commands
|
|
|
933 \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it.
|
|
|
934 These keys run commands `cperl-info-on-current-command' and
|
|
|
935 `cperl-info-on-command', which one is which is controlled by variable
|
|
|
936 `cperl-info-on-command-no-prompt' (in turn affected by `cperl-hairy').

|
938 Even if you have no info-format documentation, short one-liner-style
|
|
|
939 help is available on \\[cperl-get-help].
|
|
|
940
|
|
|
941 It is possible to show this help automatically after some idle
|
|
|
942 time. This is regulated by variable `cperl-lazy-help-time'. Default
|
|
|
943 with `cperl-hairy' is 5 secs idle time if the value of this variable
|
|
|
944 is nil. It is also possible to switch this on/off from the
|
|
|
945 menu. Requires `run-with-idle-timer'.

|
947 Variables `cperl-pod-here-scan', `cperl-pod-here-fontify',
|
|
|
948 `cperl-pod-face', `cperl-pod-head-face' control processing of pod and
|
|
|
949 here-docs sections. In a future version results of scan may be used
|
|
|
950 for indentation too, currently they are used for highlighting only.
|
|
|
951
|
|
|
952 Variables controlling indentation style:
|
|
|
953 `cperl-tab-always-indent'
|
|
|
954 Non-nil means TAB in CPerl mode should always reindent the current line,
|
|
|
955 regardless of where in the line point is when the TAB command is used.
|
|
|
956 `cperl-auto-newline'
|
|
|
957 Non-nil means automatically newline before and after braces,
|
|
|
958 and after colons and semicolons, inserted in Perl code. The following
|
|
|
959 \\[cperl-electric-backspace] will remove the inserted whitespace.
|
|
|
960 Insertion after colons requires both this variable and
|
|
|
961 `cperl-auto-newline-after-colon' set.
|
|
|
962 `cperl-auto-newline-after-colon'
|
|
|
963 Non-nil means automatically newline even after colons.
|
|
|
964 Subject to `cperl-auto-newline' setting.
|
|
|
965 `cperl-indent-level'
|
|
|
966 Indentation of Perl statements within surrounding block.
|
|
|
967 The surrounding block's indentation is the indentation
|
|
|
968 of the line on which the open-brace appears.
|
|
|
969 `cperl-continued-statement-offset'
|
|
|
970 Extra indentation given to a substatement, such as the
|
|
|
971 then-clause of an if, or body of a while, or just a statement continuation.
|
|
|
972 `cperl-continued-brace-offset'
|
|
|
973 Extra indentation given to a brace that starts a substatement.
|
|
|
974 This is in addition to `cperl-continued-statement-offset'.
|
|
|
975 `cperl-brace-offset'
|
|
|
976 Extra indentation for line if it starts with an open brace.
|
|
|
977 `cperl-brace-imaginary-offset'
|
|
|
978 An open brace following other text is treated as if it the line started
|
|
|
979 this far to the right of the actual line indentation.
|
|
|
980 `cperl-label-offset'
|
|
|
981 Extra indentation for line that is a label.
|
|
|
982 `cperl-min-label-indent'
|
|
|
983 Minimal indentation for line that is a label.
|
|
|
984
|
|
|
985 Settings for K&R and BSD indentation styles are
|
|
|
986 `cperl-indent-level' 5 8
|
|
|
987 `cperl-continued-statement-offset' 5 8
|
|
|
988 `cperl-brace-offset' -5 -8
|
|
|
989 `cperl-label-offset' -5 -8
|
|
|
990
|
|
|
991 If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'.
|
|
|
992
|

993 Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook'
