For now the only workaround is -;; to enclose offending hash characters in quotes or precede it with -;; a backslash. Note that using braces won't work -- quotes change -;; the syntax class of characters between them, while braces do not. -;; The electric-# mode helps alleviate this problem somewhat. -;; * indent-tcl-exp is untested. -;; * Doesn't work under Emacs 18 yet. -;; * There's been a report that font-lock does strange things under -;; Lucid Emacs 19.6. For instance in "proc foobar", the space -;; before "foobar" is highlighted. - -;; TODO: -;; * make add-log-tcl-defun smarter. should notice if we are in the -;; middle of a defun, or between defuns. should notice if point is -;; on first line of defun (or maybe even in comments before defun). -;; * Allow continuation lines to be indented under the first argument -;; of the preceeding line, like this: -;; [list something \ -;; something-else] -;; * There is a request that indentation work like this: -;; button .fred -label Fred \ -;; -command {puts fred} -;; * Should have tcl-complete-symbol that queries the inferior process. -;; * Should have describe-symbol that works by sending the magic -;; command to a tclX process. -;; * Need C-x C-e binding (tcl-eval-last-exp). -;; * Write indent-region function that is faster than indenting each -;; line individually. -;; * tcl-figure-type should stop at "beginning of line" (only ws -;; before point, and no "\" on previous line). (see tcl-real-command-p). -;; * overrides some comint keybindings; fix. -;; * Trailing \ will eat blank lines. Should deal with this. -;; (this would help catch some potential bugs). -;; * Inferior should display in half the screen, not the whole screen. -;; * Indentation should deal with "switch". -;; * Consider writing code to find help files automatically (for -;; common cases). -;; * `#' shouldn't insert `\#' when point is in string. - - - -;;; Code: - -;; I sure wish Emacs had a package that made it easy to extract this -;; sort of information. -(defconst tcl-using-emacs-19 (string-match "19\\." emacs-version) - "Nil unless using Emacs 19 (XEmacs or FSF).") - -;; FIXME this will break on Emacs 19.100. -(defconst tcl-using-emacs-19-23 - (string-match "19\\.\\(2[3-9]\\|[3-9][0-9]\\)" emacs-version) - "Nil unless using Emacs 19-23 or later.") - -(defconst tcl-using-xemacs-19 (string-match "XEmacs" emacs-version) - "Nil unless using XEmacs).") - -(require 'comint) - -;; When compiling under GNU Emacs, load imenu during compilation.
