       mev - a program to report mouse events

       mev [ options ]

       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 be-
       haviour. 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

       -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

       -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 num-
	      bers. 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 deci-
	      mal 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 rec-

       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  connec-
       tion stack. If an empty stack is popped the program exits.

       Other  commands	recognized  are  `info', used to return the stack depth; `quit' to prema-
       turely terminate the program; and `snapshot' to get some  configuration	information  from
       the server.

       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.
