From 6c5bcbc1b1444cc4a4160ada897301099b00f802 Mon Sep 17 00:00:00 2001 From: Stefan Monnier Date: Sun, 15 Oct 2000 04:38:24 +0000 Subject: [PATCH] (sh-imenu-generic-expression): Fix. (sh-mode-syntax-table): Add punctuation syntax for < and >. (sh-mode): Don't make all vars local here. (sh-kw): Reformat. (sh-set-shell): Use dolist. Don't set indent-region-function. (sh-mode-syntax-table): Use pop. (sh-remember-variable): Use push. (sh-help-string-for-variable): Use memq. (sh-safe-backward-sexp): Remove. (sh-safe-forward-sexp): Add ARG. (sh-get-indent-info, sh-prev-stmt): Use it. (sh-prev-line): Simplify by using forward-comment. (sh-this-is-a-continuation): Simplify. (sh-learn-buffer-indent): Use dolist. (sh-do-nothing): Remove. (sh-set-char-syntax, sh-set-here-doc-region): Use inhibit-modification-hooks. (sh-name-style): Use mapcar and push. (sh-load-style): Use dolist. (sh-save-styles-to-buffer): Use with-current-buffer and pp. (sh-case, sh-while-getopts): Use propertize directly rather than sh-electric-rparen. --- lisp/progmodes/sh-script.el | 885 +++++++++++++----------------------- 1 file changed, 328 insertions(+), 557 deletions(-) diff --git a/lisp/progmodes/sh-script.el b/lisp/progmodes/sh-script.el index 08e0e1eec48..fd225cd164a 100644 --- a/lisp/progmodes/sh-script.el +++ b/lisp/progmodes/sh-script.el @@ -113,7 +113,7 @@ ;; would make this unnecessary; simply learn the values when you visit ;; the buffer. ;; You can do this automatically like this: -; (add-hook 'sh-set-shell-hook 'sh-learn-buffer-indent) +;; (add-hook 'sh-set-shell-hook 'sh-learn-buffer-indent) ;; ;; However... `sh-learn-buffer-indent' is extremely slow, ;; especially on large-ish buffer.
