cflowwith GNU Emacs.
cflow comes with an
providing a major mode for visiting flow charts in GNU Emacs. If you
have a working
emacs on your machine, the module will be
installed somewhere in your Emacs
load-path. To load the module
at startup, add the following lines to your ‘.emacs’ or
(autoload 'cflow-mode "cflow-mode") (setq auto-mode-alist (append auto-mode-alist '(("\\.cflow$" . cflow-mode))))
The second statement associates
cflow-mode with any file having
suffix ‘.cflow’. If you prefer to have another suffix for flow
graph files, use it instead. You can also omit this option, if you do
not use any special suffix for your graph files. In this case we
recommend using ‘--emacs’ command line option. This option
generates the first line telling Emacs to use
cflow major mode
when visiting the file.
The buffer opened in
cflow mode is made read-only. The
following key bindings are defined:
Temporarily exits from
cflow mode and allows you to edit
the graph file. To resume
cflow mode type <M-x> cflow-mode
<RET>. This option is provided mainly for debugging
purposes. We do not recommend you to edit chart files, since this
will change line numbering and thus prevent
cflow mode from
correctly tracing line references.
Go to expansion of the current graph vertex. Use this key if the
point stands on a line ending with ‘[see N]’ reference. It
will bring you directly to the referenced line. Use
exchange-point-and-mark (by default <C-x C-x>) to return to
the line you examined.
If the point is standing on a recursive function, go to the next recursion. Sets mark.
If the point is standing on a recursive function, return to its definition (a recursion root). Sets mark.
Visit the referenced source file and find the function definition.
