FvwmConsoleC.pl offers editing capabilities while the user is entering the line. By
default, the line editing commands are similar to those of emacs. It also offers
substitution , which replaces a pattern to a string before it sends the command.


Functions are bound to a key or key combination to be invoked. The followings are
functions available and their default key bindings.

quote Ctrl-q

search Ctrl-s
Search pattern in history.

search_rev Ctrl-r
Search pattern in history in reverse order.

subst Meta-s
Substitute all patterns to strings and reprint the line. The substitutions
are not nested and performed in the order that they are defined.


The key binding can be overridden or defined in fvwm module configuration.

*FvwmConsole: Key \ck prev_line

Non-space character sequence need not be quoted. In order to undefine, omit the last

*FvwmConsole: Key \ck

Note that non-meta character is case sensitive. \c means control key, \e means escape,
and \m is alt key.
It also accepts Subst configuration. Users often input long fvwm command repeatedly. Subst
will replace particular input sequence to user defined string. Example:

*FvwmConsole: Subst '^bigx' 'Exec xterm -g 120x60+0+0 -fn 10x20 -fg black -bg

Typing 'bigx<return>' in FvwmConsole will launch xterm. '^' denotes the beginning of line
in regular expression. ´pl´ in the middle of the command will not be replaced. Although
the format looks different, it takes Perl regular expression. It just uses single or
double quote as the delimiter. Single or double quotes have no difference, although they
have to match, and cannot include itself in the string.

*FvwmConsole: Subst '^g\s*(\d+)' 'Desk 0 0\nGotoPage 0 $1\nFocus'

Entering 'g4' or 'g 4' will jump to desk 0 page 0 4 and focus.


FvwmConsoleC.pl should be invoked by FvwmConsole.
