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.
