;;; Commentary:
;;
;; This file contains some pre-defined generic-modes.
;;
;; INSTALLATION:
;;
;; Add this line to your .emacs file:
;;
;;   (require 'generic-x)
;;
;; You can decide which modes to load by setting the variable
;; `generic-extras-enable-list'. Some platform-specific modes are
;; affected by the variables `generic-define-mswindows-modes' and
;; `generic-define-unix-modes' (which see).
;;
;; You can also send in new modes; if the file types a reasonably common,
;; we would like to install them.
;;
;; PROBLEMS WHEN USED WITH FOLDING MODE:
;;
;; [The following relates to the obsolete selective-display technique.
;; Folding mode should use invisible text properties instead. -- Dave
;; Love]
;;
;; From Anders Lindgren <[e-mail]>
;;
;; Problem summary: Wayne Adams has found a problem when using folding
;; mode in conjuction with font-lock for a mode defined in
;; `generic-x.el'.
;;
;; The problem, as Wayne described it, was that error messages of the
;; following form appeared when both font-lock and folding are used:
;;
;; >      - various msgs including "Fontifying region...(error Stack
;; > overflow in regexp matcher)" appear
;;
;; I have just tracked down the cause of the problem.  The regexp:s in
;; `generic-x.el' does not take into account the way that folding
;; hides sections of the buffer.  The technique is known as
;; `selective-display' and has been available for a very long time (I
;; started using it back in the good old' Emacs 18 days).  Basically, a
;; section is hidden by creating one very long line were the newline
;; character (C-j) is replaced by a linefeed (C-m) character.
;;
;; Many other hiding packages, besides folding, use the same technique,
;; the problem should occur when using them as well.
;;
;; The erroronous lines in `generic-extras' look like the following (this
;; example is from the `ini' section):
;;
;;     '(("^\\(\\[.*\\]\\)"   1 'font-lock-constant-face)
;;       ("^\\(.*\\)="        1 'font-lock-variable-name-face)
;;
;; The intention of these lines is to highlight lines of the following
;; form:
;;
;; [foo]
;; bar = xxx
;;
;; However, since the `.' regexp symbol match the linefeed character the
;; entire folded section is searched, resulting in a regexp stack
;; overflow.
;;
;; Solution suggestion 2: Instead of using ".", use the sequence
;; "[^\n\r]".  This will make the rules behave just as before, but they
;; will work together with selective-display.
