(Emacs rulers do not consider it politically ;;; correct to make whistles enabled by default.) ;;; DO NOT FORGET to read micro-docs (available from `Perl' menu) <<<<<< ;;; or as help on variables `cperl-tips', `cperl-problems', <<<<<< ;;; `cperl-non-problems', `cperl-praise', `cperl-speed'. <<<<<< ;;; Additional useful commands to put into your .emacs file (before ;;; RMS Emacs 20.3): ;; (setq auto-mode-alist ;; (append '(("\\.\\([pP][Llm]\\|al\\)$" . perl-mode)) auto-mode-alist )) ;; (setq interpreter-mode-alist (append interpreter-mode-alist ;; '(("miniperl" . perl-mode)))) ;;; The mode information (on C-h m) provides some customization help. ;;; If you use font-lock feature of this mode, it is advisable to use ;;; either lazy-lock-mode or fast-lock-mode. I prefer lazy-lock. ;;; Faces used now: three faces for first-class and second-class keywords ;;; and control flow words, one for each: comments, string, labels, ;;; functions definitions and packages, arrays, hashes, and variable ;;; definitions. If you do not see all these faces, your font-lock does ;;; not define them, so you need to define them manually. Maybe you have ;;; an obsolete font-lock from 19.28 or earlier. Upgrade. ;;; If you have a grayscale monitor, and do not have the variable ;;; font-lock-display-type bound to 'grayscale, insert ;;; (setq font-lock-display-type 'grayscale) ;;; into your .emacs file (this is relevant before RMS Emacs 20). ;;;; This mode supports font-lock, imenu and mode-compile. In the ;;;; hairy version font-lock is on, but you should activate imenu ;;;; yourself (note that mode-compile is not standard yet). Well, you ;;;; can use imenu from keyboard anyway (M-x imenu), but it is better ;;;; to bind it like that: ;; (define-key global-map [M-S-down-mouse-3] 'imenu) ;;; In fact the version of font-lock that this version supports can be ;;; much newer than the version you actually have. This means that a ;;; lot of faces can be set up, but are not visible on your screen ;;; since the coloring rules for this faces are not defined. ;;; Updates: ======================================== ;;; Made less hairy by default: parentheses not electric, ;;; linefeed not magic. Bug with abbrev-mode corrected. ;;;; After 1.4: ;;; Better indentation: ;;; subs inside braces should work now, ;;; Toplevel braces obey customization. ;;; indent-for-comment knows about bad cases, cperl-indent-for-comment ;;; moves cursor to a correct place. ;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-( ;;; (50 secs on DB::DB (sub of 430 lines), 486/66) ;;; Minor documentation fixes. ;;; Imenu understands packages as prefixes (including nested). ;;; Hairy options can be switched off one-by-one by setting to null. ;;; Names of functions and variables changed to conform to `cperl-' style. ;;;; After 1.5: ;;; Some bugs with indentation of labels (and embedded subs) corrected. ;;; `cperl-indent-region' done (slow :-()). ;;; `cperl-fill-paragraph' done. ;;; Better package support for `imenu'. ;;; Progress indicator for indentation (with `imenu' loaded). ;;; `Cperl-set' was busted, now setting the individual hairy option ;;; should be better. ;;;; After 1.6: ;;; `cperl-set-style' done. ;;; `cperl-check-syntax' done. ;;; Menu done. ;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'. ;;; Bugs with `cperl-auto-newline' corrected. ;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation ;;; like $hash{. ;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de): ;;; - use `next-command-event', if `next-command-events' does not exist ;;; - use `find-face' as def. of `is-face' ;;; - corrected def. of `x-color-defined-p' ;;; - added const defs for font-lock-comment-face, ;;; font-lock-keyword-face and font-lock-function-name-face ;;; - added def. of font-lock-variable-name-face ;;; - added (require 'easymenu) inside an `eval-when-compile' ;;; - replaced 4-argument `substitute-key-definition' with ordinary ;;; `define-key's ;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'. ;;; Todo (at least): ;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz) ;;; for portable code? ;;; - should `cperl-mode' do a ;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu)) ;;; or should this be left to the user's `cperl-mode-hook'? ;;; Some bugs introduced by the above fix corrected (IZ ;-). ;;; Some bugs under XEmacs introduced by the correction corrected. ;;; Some more can remain since there are two many different variants. ;;; Please feedback! ;;; We do not support fontification of arrays and hashes under ;;; obsolete font-lock any more.

Expression and list commands understand all C brackets. Tab indents for Perl code. Paragraphs are separated by blank lines only. Delete converts tabs to spaces as it moves back. Various characters in Perl almost always come in pairs: {}, (), [], sometimes <>. When the user types the first, she gets the second as well, with optional special formatting done on {}. (Disabled by default.) You can always quote (with \\[quoted-insert]) the left \"paren\" to avoid the expansion. The processing of < is special, since most the time you mean \"less\". Cperl mode tries to guess whether you want to type pair <>, and inserts is if it appropriate. You can set `cperl-electric-parens-string' to the string that contains the parenths from the above list you want to be electrical. Electricity of parenths is controlled by `cperl-electric-parens'. You may also set `cperl-electric-parens-mark' to have electric parens look for active mark and \"embrace\" a region if possible.' CPerl mode provides expansion of the Perl control constructs: if, else, elsif, unless, while, until, continue, do, for, foreach, formy and foreachmy. and POD directives (Disabled by default, see `cperl-electric-keywords'.) The user types the keyword immediately followed by a space, which causes the construct to be expanded, and the point is positioned where she is most likely to want to be. eg. when the user types a space following \"if\" the following appears in the buffer: if () { or if () } { } and the cursor is between the parentheses. The user can then type some boolean expression within the parens. Having done that, typing \\[cperl-linefeed] places you - appropriately indented - on a new line between the braces (if you typed \\[cperl-linefeed] in a POD directive line, then appropriate number of new lines is inserted). If CPerl decides that you want to insert \"English\" style construct like bite if angry; it will not do any expansion. See also help on variable `cperl-extra-newline-before-brace'. (Note that one can switch the help message on expansion by setting `cperl-message-electric-keyword' to nil.) \\[cperl-linefeed] is a convenience replacement for typing carriage return. It places you in the next line with proper indentation, or if you type it inside the inline block of control construct, like foreach (@lines) {print; print} and you are on a boundary of a statement inside braces, it will transform the construct into a multiline and will place you into an appropriately indented blank line. If you need a usual `newline-and-indent' behaviour, it is on \\[newline-and-indent], see documentation on `cperl-electric-linefeed'. Use \\[cperl-invert-if-unless] to change a construction of the form if (A) { B } into B if A; \\{cperl-mode-map} Setting the variable `cperl-font-lock' to t switches on font-lock-mode \(even with older Emacsen), `cperl-electric-lbrace-space' to t switches on electric space between $ and {, `cperl-electric-parens-string' is the string that contains parentheses that should be electric in CPerl \(see also `cperl-electric-parens-mark' and `cperl-electric-parens'), setting `cperl-electric-keywords' enables electric expansion of control structures in CPerl. `cperl-electric-linefeed' governs which one of two linefeed behavior is preferable. You can enable all these options simultaneously (recommended mode of use) by setting `cperl-hairy' to t. In this case you can switch separate options off by setting them to `null'. Note that one may undo the extra whitespace inserted by semis and braces in `auto-newline'-mode by consequent \\[cperl-electric-backspace]. If your site has perl5 documentation in info format, you can use commands \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it. These keys run commands `cperl-info-on-current-command' and `cperl-info-on-command', which one is which is controlled by variable `cperl-info-on-command-no-prompt' and `cperl-clobber-lisp-bindings' \(in turn affected by `cperl-hairy'). Even if you have no info-format documentation, short one-liner-style help is available on \\[cperl-get-help], and one can run perldoc or man via menu. It is possible to show this help automatically after some idle time. This is regulated by variable `cperl-lazy-help-time'. Default with `cperl-hairy' (if the value of `cperl-lazy-help-time' is nil) is 5 secs idle time . It is also possible to switch this on/off from the menu, or via \\[cperl-toggle-autohelp]. Requires `run-with-idle-timer'. Use \\[cperl-lineup] to vertically lineup some construction - put the beginning of the region at the start of construction, and make region span the needed amount of lines. Variables `cperl-pod-here-scan', `cperl-pod-here-fontify', `cperl-pod-face', `cperl-pod-head-face' control processing of pod and here-docs sections. With capable Emaxen results of scan are used for indentation too, otherwise they are used for highlighting only. Variables controlling indentation style: `cperl-tab-always-indent' Non-nil means TAB in CPerl mode should always reindent the current line, regardless of where in the line point is when the TAB command is used. `cperl-indent-left-aligned-comments' Non-nil means that the comment starting in leftmost column should indent. `cperl-auto-newline' Non-nil means automatically newline before and after braces, and after colons and semicolons, inserted in Perl code. The following \\[cperl-electric-backspace] will remove the inserted whitespace. Insertion after colons requires both this variable and `cperl-auto-newline-after-colon' set. `cperl-auto-newline-after-colon' Non-nil means automatically newline even after colons. Subject to `cperl-auto-newline' setting. `cperl-indent-level' Indentation of Perl statements within surrounding block. The surrounding block's indentation is the indentation of the line on which the open-brace appears. `cperl-continued-statement-offset' Extra indentation given to a substatement, such as the then-clause of an if, or body of a while, or just a statement continuation. `cperl-continued-brace-offset' Extra indentation given to a brace that starts a substatement. This is in addition to `cperl-continued-statement-offset'. `cperl-brace-offset' Extra indentation for line if it starts with an open brace. `cperl-brace-imaginary-offset' An open brace following other text is treated as if it the line started this far to the right of the actual line indentation. `cperl-label-offset' Extra indentation for line that is a label. `cperl-min-label-indent' Minimal indentation for line that is a label. Settings for K&R and BSD indentation styles are `cperl-indent-level' 5 8 `cperl-continued-statement-offset' 5 8 `cperl-brace-offset' -5 -8 `cperl-label-offset' -5 -8 CPerl knows several indentation styles, and may bulk set the corresponding variables. Use \\[cperl-set-style] to do this. Use \\[cperl-set-style-back] to restore the memorized preexisting values \(both available from menu). If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'. Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook' with no args. DO NOT FORGET to read micro-docs (available from `Perl' menu) or as help on variables `cperl-tips', `cperl-problems', `cperl-non-problems', `cperl-praise', `cperl-speed'."
