[copy.pl] add gpm copybuffer

[vague666]

@bw1
It might be possible to use gpm to copy text if in non-X env
There should be a fifo called /dev/gpmdata

Don't know without testing myself if it's possible to write data to gpmdata and paste with mouse middle-button, also, no idea if gpm has to be started with -R for gpmdata to be created
Something to test :)

What is the question?

[bw1]

i read. the fifo speaks a mouse protocol and the fifo is for reading.

fifo /dev/gpmdata in protocol name
                             ^^^^^

where can i put the string?

[vague666]

The gpm daemon must be started with -R, for example -Rms3 (this worked for me)
Then I could do echo test > /dev/gpmdata; cat /dev/gpmdata
Although the cat didn't exit, but attempted to read more from gpmdata, not sure if that can be modified

[bw1]

bash-4.3# echo test > /dev/gpmdata; cat /dev/gpmdata
C>C<C<C;C<C;C<C<C<C<C<C<C=C=C>C?C?L>L>L=L;L:L9L:L9L:L;L;L;L;L<L<L>L>L?L?L?@L?L?@@L?@L?@L?L?L?L?test

[vague666]

Try some other mouse types is all I can say. I tested in a centos vm, change both -t and -R to the gpm daemon

[bw1]

[src ]$ print **/(*.c|*.h) |xargs grep fifofd
daemon/getmousedata.c:   if (kd_mode!=KD_TEXT && fifofd != -1 && opt_rawrep)
daemon/getmousedata.c:      write(fifofd, data, howmany);
daemon/getmousedata.c:         if (kd_mode!=KD_TEXT && fifofd != -1 && opt_rawrep && j > 0)
daemon/getmousedata.c:            write(fifofd, edata-i, j);
daemon/gpm.c:int fifofd=-1;
daemon/processmouse.c:      if (fifofd != -1 && ! opt_rawrep) {

man:console_ioctl

TIOCLINUX, subcode=2
    Set selection. argp points to a 

    struct {
       char  subcode;
       short xs, ys, xe, ye;
       short sel_mode;
    };

    xs and ys are the starting column and row. xe and ye are the ending column and row. (Upper left corner is row=column=1.) sel_mode is 0 for character-by-character selection, 1 for word-by-word selection, or 2 for line-by-line selection. The indicated screen characters are highlighted and saved in the static array sel_buffer in devices/char/console.c. 
TIOCLINUX, subcode=3
    Paste selection. The characters in the selection buffer are written to fd.

Not really sure what I should do with the fifoexample

$> ./run.sh

mkfifo fifo
./openfifo&
echo 'ein test' > fifo
cat fifo

[vague666]

I still don't know what that is supposed to mean. Why the c program?
/dev/gpmdata is created when the gpm daemon is run with -R, after that you can redirect data to the device and read from it. Depending on the mouse type the data might be dirty with protocol bits but changing -t and -R until the data is valid should work
In the script just add writing to /dev/gpmdata to paste from irssi and document the need for -R, like I said, -Rms3 worked for me and might work for others

I run all my centos without X. If you have possibility to try on a system without X please do but I don't think the fifo means X is/has to be installed, just that any mouse data in graphic mode, could mean both vesafb and X I guess, will be repeated in /dev/gpmdata, nothing stops you from using the device to move data around, ie echo test > /dev/gpmdata; cat /dev/gpmdata, but the fifo will only be created if you start gpm with -R[type/protocol]

[vague666]

-R[name]
Causes gpm to act as a repeater: any mouse data received while in graphic mode will be produced on the fifo /dev/gpmdata in protocol name, given as an optional argument (no space in between !). In principle, you can use the same names as for the -t option, although repeating into some protocols may not be implemented for a while. In addition, you can specify raw as the name, to repeat the mouse data byte by byte, without any protocol translation. If name is omitted, it defaults to msc. Using gpm in repeater mode, you can configure the X server to use its fifo as a mouse device. This option is useful for bus-mouse owners to override the single-open limitation. It is also an easy way to manage those stupid dual-mode mice which force you to keep the middle button down while changing video mode. The option is forced on by the -M option.

[bw1]

/etc/rc.d/rc.gpm

# There is another way to run GPM, where it acts as a repeater outputting a
# virtual MouseSystems mouse on /dev/gpmdata.  This is useful for feeding
# gpm's data to X, especially if you've got a busmouse (in that situation X
# and gpm may not coexist without using a repeater).  To try running a GPM
# repeater for X, change the gpm command line to look like this:
# /usr/sbin/gpm -R msc -m /dev/mouse -t ps2
# Then, make sure that the mouse configuration in your XF86Config file refers
# to the repeater device (/dev/gpmdata) and a MouseSystems mouse type.  If you
# edit the file directly, you'll want the lines to look like this (minus the
# comment marks '#' shown here, of course):
#Section "Pointer"
#    Protocol    "MouseSystems"
#    Device      "/dev/gpmdata"

[vague666]

I don't know what you mean by that. X is not required from what I can see. Just add a possibility to print data to /dev/gpmdata to the script and document the need to run gpm with -R

[bw1]

/dev/gpmdata is a output of gpm.

[vague666]

/dev/gpmdata is created when gpm is run with -R. It's a normal fifo, you can write to it and read from it. X has no bearing on it in this case

Just add a possibility to print data to /dev/gpmdata to the script

This is completely wrong. /dev/gpmdata is not for passing text around.
