=head1 NAME
selection-pastebin - automatic pastebin upload
=head1 DESCRIPTION
This is a little rarely useful extension that uploads the selection as
textfile to a remote site (or does other things). (The implementation is
not currently secure for use in a multiuser environment as it writes to
F</tmp> directly.).
It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
i.e.
URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
Pressing this combination runs a command with C<%> replaced by the name of
the textfile. This command can be set via a resource:
URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
And the default is likely not useful to anybody but the few people around
here :)
The name of the textfile is the hex encoded md5 sum of the selection, so
the same content should lead to the same filename.
After a successful upload the selection will be replaced by the text given
in the C<selection-pastebin-url> resource (again, the % is the placeholder
for the filename):
URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
the double C</> characters as comment start. Use C<\057\057> instead,
which works regardless of whether xrdb is used to parse the resource file
or not.
