clipmenu is a simple clipboard manager using [dmenu][] (or [rofi][]) and
|
|
[xsel][].
|
|
|
|
# Demo
|
|
|
|
|
|
|
|
# Usage
|
|
|
|
Start `clipmenud`, then run `clipmenu` to select something to put on the
|
|
clipboard.
|
|
|
|
A systemd user service for starting clipmenud is included at
|
|
[init/clipmenud.service](https://github.com/cdown/clipmenu/blob/develop/init/clipmenud.service).
|
|
|
|
All args passed to clipmenu are transparently dispatched to dmenu. That is, if
|
|
you usually call dmenu with args to set colours and other properties, you can
|
|
invoke clipmenu in exactly the same way to get the same effect, like so:
|
|
|
|
clipmenu -i -fn Terminus:size=8 -nb '#002b36' -nf '#839496' -sb '#073642' -sf '#93a1a1'
|
|
|
|
# How does it work?
|
|
|
|
The code is fairly simple and easy to follow, you may find it easier to read
|
|
there, but it basically works like this:
|
|
|
|
## clipmenud
|
|
|
|
1. `clipmenud` polls the clipboard every 0.5 seconds (or another interval as
|
|
configured with the `CM_SLEEP` environment variable). Unfortunately there's
|
|
no interface to subscribe for changes in X11, so we must poll.
|
|
|
|
Instead of polling, you can bind your copy key binding to also issue
|
|
`CM_ONESHOT=1 clipmenud`. However, there's no generic way to do this, since
|
|
any keys or mouse buttons could be bound to do this action in a number of
|
|
ways.
|
|
2. If `clipmenud` detects changes to the clipboard contents, it writes them out
|
|
to the cache directory.
|
|
|
|
## clipmenu
|
|
|
|
1. `clipmenu` reads the cache directory to find all available clips.
|
|
2. `dmenu` is executed to allow the user to select a clip.
|
|
3. After selection, the clip is put onto the PRIMARY and CLIPBOARD X
|
|
selections.
