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 console
       events it gets, both keyboard and mouse events.


       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 Emacs Support.


       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, Margins.

       -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 adn 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.


       The only other commands recognized are info, used to return the stack
       depth, and quit to premautrely terminate the program.
