fs

Shows disk space usage for a set partition.

Displays a notification when the partition is full or has low space.

mypartition = lain.widgets.fs()

Input table

Variable	Meaning	Type	Default
timeout	Refresh timeout seconds -	int	600
partition	Partition to monitor	string	"/"
options	Additional options to pass to dfs	string, in the form `--type='fstype'	--exclude-type='fstype'`
notification_preset	Notification preset	table	{ fg = beautiful.fg_normal }
followtag	Display the notification on currently focused screen	boolean	false
notify	Display notifications	string	"on"
showpopup	Display df popups with mouse hovering	string, possible values: "on", "off"	"on"
settings	User settings	function	empty function

settings can use the following partition related float values:

• fs_now.available
• fs_now.size_mb
• fs_now.size_gb
• fs_now.used
• fs_now.used_mb
• fs_now.used_gb

Within settings, you can obtain other partition values from internal fs_info table. For each partition, the following indexes are available:

• fs_info[other_partition .. " avail_p"]
• fs_info[other_partition .. " size_mb"]
• fs_info[other_partition .. " size_gb"]
• fs_info[other_partition .. " used_p"]
• fs_info[other_partition .. " used_mb"]
• fs_info[other_partition .. " used_gb"]

just like the variables of fs_now. Example:

-- shows root and home partitions percentage used
fsroothome = lain.widgets.fs({
    settings  = function()
        local home_used = tonumber(fs_info["/home used_p"]) or 0
        widget:set_text("/ " .. fs_now.used .. "% | /home " .. home_used .. "% ")
    end
})

Also, settings can modify notification_preset table. This table will be the preset for the naughty notifications. Check here for the list of variables it can contain. Default definition:

notification_preset = { fg = beautiful.fg_normal }

In multiple screen setups, the default behaviour is to show a visual notification pop-up window on the first screen. By setting followtag to true it will be shown on the currently focused tag screen.

Output table

Variable	Meaning	Type
widget	The widget	wibox.widget.textbox
show	The notification	function

You can display the notification with a key binding like this:

awful.key({ altkey }, "h", function () mypartition.show(seconds, scr) end),

where altkey = "Mod1" and show arguments, all optionals, are:

• seconds, notification time in seconds
• scr, screen in which display the notification

Note that naughty notifications requires beautiful.font or notification_preset.font to be monospaced, in order to correctly display the output.
