mev
SYNOPSIS
mev [ options ]
DESCRIPTION
The `mev' program is part of the gpm package. The infor
mation below is extracted from the texinfo file, which is
the preferred source of information.
The mev program is modeled after xev. It prints to stdout
the mouse console events it gets.
mev's default behaviour is to get anything, but command
line switches can be used to set the various fields in the
Gpm_Connect structure, in order to customize the program's
behaviour. I'm using mev to handle mouse events to Emacs.
Command line switches for mev are the following:
-C number
Select a virtual console to get events from. This
is intended to be used for debugging.
-d number
Choose a default mask. By default the server gets
any events not belonging to the event mask. The
mask can be provided either as a decimal number, or
as a symbolic string.
-e number
Choose the event mask. By default any event is
received. The mask can be provided either as a dec
imal number, or as a symbolic string.
-E Enter emacs mode. In emacs mode events are reported
as lisp forms rather than numbers. This is the for
mat used by the t-mouse package within emacs.
-f Fit events inside the screen before reporting them.
This options re-fits drag events, which are allowed
to exit the screen border,
-i Interactive. Accepts input from stdin to change
connection parameters.
-m number
Choose the minimum modifier mask. Any event with
fewer modifiers will not be reported to mev. It
defaults to 0. The mask must be provided either as
When the arguments are not decimal integers, they are con
sidered lists of alphanumeric characters, separated by a
single non-alphanumeric character. I use the comma (,),
but any will do.
Allowed names for events are move, drag, down or press, up
or release, motion (which is both move and drag), and
hard.
Allowed names for modifiers are shift, leftAlt, rightAlt,
anyAlt (one or the other), control.
When the -i switch is specified, mev looks at its standard
input as command lines rather than events. The input lines
are parsed, and the commands push and pop are recognized.
The push command, then, accepts the options -d, -e, -m and
-M, with the same meaning described above. Unspecified
options retain the previous value and the resulting masks
are used to reopen the connection with the server. pop is
used to pop the connection stack. If an empty stack is
popped the program exits.
Other commands recognized are info, used to return the
stack depth; quit to prematurely terminate the program;
and snapshot to get some configuration information from
the server.
BUGS
Beginning with release 1.16, mev no longer works under
xterm. Please use the rmev program (provided in the sam
ple directory) to watch gpm events under xterm or rxvt.
rmev also displays keyboard events besides mouse events.
