This plugin will set your status to **away** if you detach your screen.
|
|
|
|
The default behaviour is to check for both tmux and screen (in that order).
|
|
|
|
Configuration options
|
|
---------------------
|
|
|
|
.. glossary::
|
|
|
|
use_screen
|
|
**Default:** ``true``
|
|
|
|
Try to find an attached screen.
|
|
|
|
use_tmux
|
|
**Default:** ``true``
|
|
|
|
Try to find and attached tmux.
|
|
|
|
use_csi
|
|
**Default:** ``false``
|
|
|
|
Use `client state indication`_ to limit bandwidth (thus CPU) usage when detached. WARNING: using CSI together with chatrooms will result in inaccurate logs due to presence filtering or other inaccuracies.
