From db133cb6032095e0efe127e3bd09f6aa595a16cd Mon Sep 17 00:00:00 2001 From: "Richard M. Stallman" Date: Sat, 30 May 1998 15:43:16 +0000 Subject: [PATCH] (cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani and Nick Roberts . (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added. (cperl-find-pods-heres): Message for termination of scan corrected. (cperl-speed): New variable with hints. (cperl-electric-else): Make backspace electric after expansion of `else/continue' too. Fixed customization to honor cperl-hairy. Created customization groups. All the compile-time warnings fixed. (cperl-syntaxify-by-font-lock): Interaction with `font-lock-hot-pass' fixed. (cperl-after-block-and-statement-beg): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p, cperl-after-expr-p): Likewise. (cperl-indent-region): Make a marker for END - text added/removed. (cperl-style-alist): Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise.
