mev - a program to report mouse events
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 pro
gram'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
as a decimal number, or as a symbolic string.
-M number
Choose the maximum modifier mask. Any event with
more modifier than specified will not be reported
to `mev'. It defaults to ` ~0', i.e. all events
are received. The mask must be provided either as
a decimal number, or as a symbolic string.
-p Requests to draw the pointer during drags. This
option is used by emacs to avoid invoking `ioctl()'
from lisp code.
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', `righ
tAlt', `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
rmev also displays keyboard events besides mouse events.
