Togglempc is a small REST server that accepts HTTP post requests to toggle MPD on and off and switch playlist. (It is a client to MPD.) MPD is Music Play Daemon, see https://www.musicpd.org/.
Home automation or smart switches can use it to control MPD instances.

If you use openHAB, here is an example for two openhab rules to control MPD (it assumes you have already two switches named Kitchen_music_on_off and Kitchen_music_channel):
```
rule "toggle play kitchen"
when
Item Kitchenmusicon_off received command
then
sendHttpPostRequest("http://192.168.1.25:8000/mpd/kitchen/toggle-play")
end
rule "switch playlist kitchen" when Item Kitchenmusicchannel received command then sendHttpPostRequest("http://192.168.1.25:8000/mpd/kitchen/switch-playlist") end ```
Currently togglempc only supports to commands namely toggle-play and switch-playlist. But it could easily be extended to support other commands like skip song or increase/decrease volume. See src/main.rs and src/toggle_mpc.rs how the current commands are implemented.
Togglempc uses Rocket to accept HTTP post requests.
Therefore you need to switch to rust nightly to compile (see https://rocket.rs/v0.5/guide/getting-started/ for details):
cd <path-to-my-clone-of-togglmpc>
rustup override set nightly
cargo run sample-config.toml
Togglempc needs a configuration file in which the playlists and the MPDs are configured. See sample-config.toml for documentation.
