### Description
|
||
|
|
|
||
|
|
Shows file systems informations.
|
||
|
|
|
||
|
|
If a partition is given in input, a notification will be displayed when it is almost full.
|
||
|
|
|
||
|
|
```lua
|
||
|
|
local mypartition = lain.widget.fs()
|
||
|
|
```
|
||
|
|
|
||
|
|
## Input table
|
||
|
|
|
||
|
|
Variable | Meaning | Type | Default
|
||
|
|
--- | --- | --- | ---
|
||
|
|
`timeout` | Refresh timeout (in seconds) | integer | 600
|
||
|
|
`partition` | (Optional) Partition to watch: a notification will be displayed when full | string | `nil`
|
||
|
|
`threshold` | Percentage threshold at which the notification is triggered | integer | 99
|
||
|
|
`notification_preset` | Notification preset | table | See [default `notification_preset`](https://github.com/lcpz/lain/wiki/fs#default-notification_preset)
|
||
|
|
`followtag` | Display the notification on currently focused screen | boolean | false
|
||
|
|
`showpopup` | Display popups with mouse hovering | string, possible values: "on", "off" | "on"
|
||
|
|
`settings` | User settings | function | empty function
|
||
|
|
|
||
|
|
`settings` can use the table `fs_now`, which contains a string entry for each file system path available. For instance, root infos are located in the variable `fs_now["/"]`. Every entry in this table have the following variables:
|
||
|
|
|
||
|
|
Variable | Meaning | Type
|
||
|
|
--- | --- | ---
|
||
|
|
`units` | (multiple of) units used | string ("Kb", "Mb", "Gb", and so on)
|
||
|
|
`percentage` | the used percentage | integer
|
||
|
|
`size` | size in `units` of the given fs | float
|
||
|
|
`used` | amount of space used in the given fs, expressed in `units` | float
|
||
|
|
`free` | amount of free space in the given fs, expressed in `units` | float
|
||
|
|
|
||
|
|
Usage example:
|
||
|
|
|
||
|
|
```lua
|
||
|
|
-- shows used (percentage) and remaining space in home partition
|
||
|
|
local fsroothome = lain.widget.fs({
|
||
|
|
settings = function()
|
||
|
|
widget:set_text("/home: " .. fs_now["/home"].percentage .. "% (" ..
|
||
|
|
fs_now["/home"].free .. " " .. fs_now["/home"].units .. " left)")
|
||
|
|
end
|
||
|
|
})
|
||
|
|
-- output example: "/home: 37% (239.4 Gb left)"
|
||
|
|
```
|
||
|
|
|
||
|
|
With multiple screens, 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.
|
||
|
|
|
||
|
|
### Default `notification_preset`
|
||
|
|
|
||
|
|
```lua
|
||
|
|
notification_preset = {
|
||
|
|
font = "Monospace 10",
|
||
|
|
fg = "#FFFFFF",
|
||
|
|
bg = "#000000"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## 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:
|
||
|
|
|
||
|
|
```lua
|
||
|
|
awful.key({ altkey }, "h", function () mypartition.show(seconds, scr) end),
|
||
|
|
```
|
||
|
|
|
||
|
|
where ``altkey = "Mod1"`` and ``show`` arguments, both optionals, are:
|
||
|
|
|
||
|
|
* `seconds`, notification time in seconds
|
||
|
|
* `scr`, screen which to display the notification in
|
||
|
|
|
||
|
|
## Note
|
||
|
|
|
||
|
|
Naughty notifications require `notification_preset.font` to be **monospaced**, in order to correctly display the output.
