-;;; libxml-doc.el - look up libxml-symbols and start browser on documentation

-
-;; these functions allow you to browse the libxml documentation
-;; (using lynx within emacs by default)
-;;
-;; ----- Installing
-;; 1. add the following to ~/.emacs (adapt path and remove comments !)
-;; (autoload 'libxmldoc-lookup-symbol "~/elisp/libxml-doc" 
-;;  "Look up libxml-symbols and start browser on documentation." t)
-;; or put this file in load-path and use this:
-;; (autoload 'libxmldoc-lookup-symbol "libxml-doc"
-;;  "Look up libxml-symbols and start browser on documentation." t)
-;;
-;; 2. adapt libxmldoc-root:
-;; i.e. (setq libxmldoc-root "~/libxml2-2.0.0/doc/html")
-;;
-;; 3. change the filter-regex: by default, cpp-defines, callbacks and
-;; html-functions are excluded (C-h v libxmldoc-filter-regexp)
-;;
-;; 4. consider customizing libxmldoc-browse-url (lynx by default);
-;; cannot use Emacs/W3 4.0pre46 because it has problems with the html
-;;
-;; ----- Using
-;; call M-x libxmldoc-lookup-symbol: this will prompt with completion and
-;; then open the browser showing the documentation. If the word around the
-;; point matches a symbol, that is used instead.  You can also call
-;; libxmldoc-lookup-symbol noninteractively and pass the symbol.
-
-;; Note:
-;; an alternative to libxml-doc is emacs tags:
-;; $ cd libxml2-2.3.8
-;; $ make TAGS
-;; $ emacs
-;; M-. (M-x find-tag) ...  or
-;; M-x tags-search ... RET M-, M-, ...
-;; (for more information: info emacs RET m Tags RET)

- ;;; ChangeLog:
-;; Wed Jun 21 01:07:12 2000: initial release
-;; Wed Jun 21 01:45:29 2000: added libxmldoc-lookup-symbol-at-point
-;; Wed Jun 21 23:37:58 2000: libxmldoc-lookup-symbol now uses
-;; (thing-at-point 'word) if it matches a symbol
-;; Thu Jun 22 02:37:46 2000: filtering is only done for completion
-;; Thu Jun 22 21:03:41 2000: libxmldoc-browse-url can be customized
-;; Thu May 31 2001 (Geert): 
-;;       - Changed the `gnome-xml-' html file prefix into `libxml-'.
-;;       - Changed the 'word match from thing-at-point into 'symbol.
-;;         With 'word, identifiers with an underscore (e.g. BAD_CAST)
-;;         don't get matched.
-;; Fri Jun  8 16:29:18 2001, Sat Jun 23 16:19:47 2001:
-;; complete rewrite of libxmldoc-lookup-symbol
-;; by Felix Natter <fnatter@gmx.net>, Geert Kloosterman <geertk@ai.rug.nl>:
-;;       - Now keeps the list of symbols between calls to speed things up.
-;;       - filtering is only used when no symbol is passed and
-;;       thing-at-point does not match a symbol and "*" + thing-at-point
-;;       does not match a symbol (this is used to catch callbacks) and
-;;       libxmldoc-filter-regexp is non-nil.
-;; Sat Jun 23 16:20:34 2001: update the docstrings
-;; Sat Jun 23 16:22:54 2001 (Geert Kloosterman <geertk@ai.rug.nl>):
-;; update README: use autoload instead of load+c-mode-hook
-;; Sat Jul 7 19:00:31 2001: fixed a problem with XEmacs: the
-;; string-match of XEmacs when used in completing-read used the
-;; minibuffer's value of case-fold-search, and not the one in the
-;; c-mode buffer that we had set => so there's a new *-string-match-cs
-;; (case sensitive) function which binds case-fold-search and runs string-match
-;; Wed Sep 1 20:26:29 2004: adapted for libxml2-2.6.9: handle
-;; document-relative (#XXX) links
-
-;;; TODO:
-;; - use command-execute for libxmldoc-browse-url
-;; - keep (match-string 1) in a variable (libxmldoc-get-list-of-symbols)
-;;   (only if it improves performance)
-;; - check the (require ..)-statements
