Integration with external applications

You may want to provide information about windows, tags, outputs, etc. to external applications.

You can spin up both one-off and long-running scripts with the Lua API to provide information to the application. You could do it with the Rust API as well, but I recommend using the Lua API to not have to deal with Cargo projects and build artifacts everywhere.

For example, eww allows you to run scripts to provide data to widgets. You can write a small Lua script that uses the run function to provide one-off information, or use the setup function similarly to a normal config for something that subscribes to data changes.

require("pinnacle").run(function()
    print(require("pinnacle.output").get_focused().name)
end)

require("pinnacle").setup(function()
    require("pinnacle.tag").connect_signal({
        tag_active = function(tag, active)
            -- Output data in the necessary format here
        end
    })
end)
