pipewire widget with pactl

[fakeGenuis]

For someone use pipewire as the low-level multimedia framework, the pacmd may not available, there is pactl instead (see pacmd - Migrate PulseAudio). And it's outputs is different with those in pulse.lua, so i change pulse.lua a little to a new file pipewire.lua.

Thank you for this, there are a couple of things to fix.

It should go to widget/contrib, and needs a wiki entry.

Here is my simplified version, can add pull request if needed

local helpers = require("lain.helpers")
local shell   = require("awful.util").shell
local wibox   = require("wibox")
local string  = string

-- Pipewire volume
-- lain.widget.contrib.pipewire

local function factory(args)
    args = args or {}

    local pipewire    = { widget = args.widget or wibox.widget.textbox(), device = "N/A" }
    local timeout  = args.timeout or 5
    local settings = args.settings or function() end

    pipewire.cmd = "echo \"Volume: $(pactl get-sink-volume @DEFAULT_SINK@ | awk -F '/' 'NF > 0 {print $4}' | sed 's/^[ \t]*//;s/[ \t]*$//')\"; pactl get-sink-mute @DEFAULT_SINK@"

    function pipewire.update()
        helpers.async({ shell, "-c", pipewire.cmd },
            function(s)
                volume_now = {
                    muted = string.match(s, "Mute: (%S+)") or "N/A",
                    value = string.match(s, "Volume: (%d+)%%") or "N/A/",
                }

                widget = pipewire.widget
                settings()
            end)
    end

    helpers.newtimer("pipewire", timeout, pipewire.update)

    return pipewire
end

return factory

How to use it (an example...)

local volume = lain.widget.pipewire {
    settings = function()
        vlevel = "V " .. volume_now.value .. "% "
        if volume_now.muted == "yes" then
            vlevel = vlevel .. "M"
        end
        widget:set_markup(lain.util.markup("#7493d2", vlevel .. " "))
    end
}

At this point, you can simply use a watcher. The following example assumes a stereo configuration.

local volume = awful.widget.watch(
    "pactl get-sink-volume @DEFAULT_SINK@ | cut -s -d/ -f2,4; pactl get-sink-mute @DEFAULT_SINK@",
    5, -- timeout seconds
    function(widget, stdout)
        local volume = "Volume: "
        for v in stdout:gmatch("(%d+%%)") do volume = volume .. " " .. v end
        if #volume == 8 then volume = "N/A" -- if previous loop didn't match anything
        local mute = string.match(stdout, "Mute: (%S+)") or "N/A"

        -- customize here
        widget:set_markup(volume .. " " .. mute)
    end
)

It should be done automatically 🤔

Oh lol! I remember now, there is this "Travis no longer offers a free tier" story that we need to resolve by switching to GitHub Actions.
