Can use linear algorithm for indentation if Emacs supports it.
(cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.
