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 pack-
	      age 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 previ-
       ous  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.
