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.
