6 mev - a program to report mouse events
7
9 mev [ options ]
10
12 The `mev' program is part of the gpm package. The information below is
13 extracted from the texinfo file, which is the preferred source of
14 information.
15 The mev program is modeled after xev. It prints to stdout the mouse
18 console events it gets.
19 mev's default behaviour is to get anything, but command line switches
22 can be used to set the various fields in the Gpm_Connect structure, in
23 order to customize the program's behaviour. I'm using mev to handle
24 mouse events to Emacs.
25 Command line switches for mev are the following:
28 -C number
30 Select a virtual console to get events from. This is intended
31 to be used for debugging.
32 -d number
34 Choose a default mask. By default the server gets any events not
35 belonging to the event mask. The mask can be provided either as
36 a decimal number, or as a symbolic string.
37 -e number
39 Choose the event mask. By default any event is received. The
40 mask can be provided either as a decimal number, or as a sym‐
41 bolic string.
42 -E Enter emacs mode. In emacs mode events are reported as lisp
44 forms rather than numbers. This is the format used by the t-
45 mouse package within emacs.
46 -f Fit events inside the screen before reporting them. This options
48 re-fits drag events, which are allowed to exit the screen bor‐
49 der,
50 -i Interactive. Accepts input from stdin to change connection
53 parameters.
54 -m number
56 Choose the minimum modifier mask. Any event with fewer modifiers
57 will not be reported to mev. It defaults to 0. The mask must be
58 provided either as a decimal number, or as a symbolic string.
59 -M number
61 Choose the maximum modifier mask. Any event with more modifier
62 than specified will not be reported to mev. It defaults to ~0,
63 i.e. all events are received. The mask must be provided either
64 as a decimal number, or as a symbolic string.
65 -p Requests to draw the pointer during drags. This option is used
67 by emacs to avoid invoking ioctl() from lisp code.
68 When the arguments are not decimal integers, they are considered lists
71 of alphanumeric characters, separated by a single non-alphanumeric
72 character. I use the comma (,), but any will do.
73 Allowed names for events are move, drag, down or press, up or release,
76 motion (which is both move and drag), and hard.
77 Allowed names for modifiers are shift, leftAlt, rightAlt, anyAlt (one
80 or the other), control.
81 When the -i switch is specified, mev looks at its standard input as
84 command lines rather than events. The input lines are parsed, and the
85 commands push and pop are recognized.
86 The push command, then, accepts the options -d, -e, -m and -M, with the
89 same meaning described above. Unspecified options retain the previous
90 value and the resulting masks are used to reopen the connection with
91 the server. pop is used to pop the connection stack. If an empty stack
92 is popped the program exits.
93 Other commands recognized are info, used to return the stack depth;
96 quit to prematurely terminate the program; and snapshot to get some
97 configuration information from the server.
98
101 Beginning with release 1.16, mev no longer works under xterm. Please
102 use the rmev program (provided in the sample directory) to watch gpm
103 events under xterm or rxvt. rmev also displays keyboard events besides
104 mouse events.
