Sending commands from shell script to Pinnacle

[justinesmithies]

Is it possible to send commands ran from a bash script as you can using say swaymsg with Pinnacle ?
Thanks in advance and thank you for what looks to be a really fantastic tiling wm. I've been reading through the api and I can't wait to try it on my Void system.

Yes, but you'll need to use the Lua API and either

1. Pipe Lua code into lua:

   echo "<your Lua here>" | lua

   or
2. Run Lua files from bash:

   lua <your Lua file>

If you're not limited to bash you can also run executable Lua files directly.

For the specifics, you can run the run function (not setup, this will block):

require("pinnacle").run(function(Pinnacle)
    -- Anything you can run in a normal Lua config you can use here
end)

Just note the following caveats:

• Setting a keybind will overwrite any current keybinds set, and because run returns you'll lose those keybinds. This may be changed in the future to allow for use cases like setting a keybind outside the config.
• You can't connect to signals, again because the script will return.
• You won't be able to get output from spawned processes for the same reason.

If you need to print output from the script in json you can install cjson from Luarocks:

luarocks install --local lua-cjson

and print tables as json with

print(require("cjson").encode(<your table here>))
