NAME¶
mev - a program to report mouse events
SYNOPSIS¶
mev [
options ]
DESCRIPTION¶
The `mev' program is part of the gpm package. The information 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 decimal 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 format 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 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 considered 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
sample directory) to watch gpm
events under xterm or rxvt.
rmev also displays keyboard events besides
mouse events.
