This is a port of awesome-vain to Awesome 3.5.x.

I started hacking this too much that it became something else.

So I decided to undo the commits for keeping the original module, in respect of the great work of his creator, and to create a separate one for my own stuff.

*~ here follows the original readme ~*

This repository contains stuff I wrote for the Awesome Window Manager. Essentially, it contains everything I use in my rc.lua that is not trivial: Widgets, layouts, utility functions. This means, the stuff in here is exceedingly customized to fit my needs. Thus, you shouldn't blindly use it. It's likely for things to get changed or removed or whatever. Rather than actually using it, read the code. :)

All of this is GPL3+.

Installation

git clone https://github.com/copycat-killer/vain-again.git ~/.config/awesome/vain

Using it

Basically, all you have to do is including the module:

require("vain")
vain.widgets.terminal = "xterm"

Some widgets require a terminal, so you need to set that as well. terminal may also be a lua function that accepts one parameter. Something like this:

function footerm(cmd)
    awful.util.spawn("xterm -e " .. cmd)
end

vain.widgets.terminal = footerm

While this particular is pretty useless, you may come up with something clever.

Furthermore, the directory vain must be located in the same directory as your rc.lua.

$ pwd
/home/void/.config/awesome
$ tree -l
.
|-- rc.lua
|-- themes -> ../.awesome-themes/
|   |-- ...
|   `-- ...
`-- vain -> ../.awesome-vain/vain
    |-- init.lua
    |-- layout
    |   |-- browse.lua
    |   |-- gimp.lua
    |   |-- init.lua
    |   |-- termfair.lua
    |   `-- uselessfair.lua
    |-- util.lua
    `-- widgets.lua

Layouts

How do layouts work in general?

A "layout" is simply a lua table or module that has an attribute name and a function called arrange. So the most simple layout could look like this:

mylayout = {}
mylayout.name = "hurz"
mylayout.arrange = function(p) end

To use this layout on a tag, you have to write:

awful.layout.set(mylayout, tags[1][7])

(Of course, you could just add it to the default table called layouts.)

Now, the arrange function gets a parameter p which is another table. The most important elements of this table are workarea and clients. Thus, the table p looks similar to this:

p = {
    workarea = { x, y, width, height },
    clients = { ... },
    ...
}

The job of the arrange function is to iterate over all clients and set their geometry. That is, for each client you have to call geometry on it:

mylayout.arrange = arrange(p)

    local wa = p.workarea
    local cls = p.clients

    for k, c in ipairs(cls)
    do
        local g = {}

        g.width = ...
        g.height = ...
        g.x = wa.x + ...
        g.y = wa.y + ...

        c:geometry(g)
    end
end

That's it. Awesome handles all the nasty stuff like minimized clients, floating clients, order of clients, focus, drawing window borders etc.

What about icons?

Thanks to Nicolas Estibals (https://github.com/nestibal) for creating icons for Awesome's default theme!

You have to extend your theme like this (let's say this file is called ~/.config/awesome/extended_default_theme.lua):

dofile("/usr/share/awesome/themes/default/theme.lua")
...
theme.layout_termfair      = os.getenv("HOME") .. "/.config/awesome/vain/themes/default/layouts/termfairw.png"
theme.layout_browse        = os.getenv("HOME") .. "/.config/awesome/vain/themes/default/layouts/browsew.png"
theme.layout_gimp          = os.getenv("HOME") .. "/.config/awesome/vain/themes/default/layouts/gimpw.png"
theme.layout_cascade       = os.getenv("HOME") .. "/.config/awesome/vain/themes/default/layouts/cascadew.png"
theme.layout_cascadebrowse = os.getenv("HOME") .. "/.config/awesome/vain/themes/default/layouts/cascadebrowsew.png"
theme.layout_centerwork    = os.getenv("HOME") .. "/.config/awesome/vain/themes/default/layouts/centerworkw.png"
...
return theme

Then, you can tell beautiful to use this extended theme:

beautiful.init(os.getenv("HOME") .. "/.config/awesome/extended_default_theme.lua")

Icons for the default theme are available in black and white. There's also a set of icons for the "zenburn" theme (this is what I use).

What do my layouts do?

termfair

I do a lot of work on terminals. The common tiling algorithms usually maximize windows, so you'll end up with a terminal that has about 200 columns or more. That's way too much. Have you ever read a manpage in a terminal of this size?

This layout restricts the size of each window. Each window will have the same width but is variable in height. Furthermore, windows are left-aligned. The basic workflow is as follows (the number above the screen is the number of open windows, the number in a cell is the fixed number of a client):

     (1)                (2)                (3)
+---+---+---+      +---+---+---+      +---+---+---+
|   |   |   |      |   |   |   |      |   |   |   |
| 1 |   |   |  ->  | 2 | 1 |   |  ->  | 3 | 2 | 1 |  ->
|   |   |   |      |   |   |   |      |   |   |   |
+---+---+---+      +---+---+---+      +---+---+---+

     (4)                (5)                (6)
+---+---+---+      +---+---+---+      +---+---+---+
| 4 |   |   |      | 5 | 4 |   |      | 6 | 5 | 4 |
+---+---+---+  ->  +---+---+---+  ->  +---+---+---+
| 3 | 2 | 1 |      | 3 | 2 | 1 |      | 3 | 2 | 1 |
+---+---+---+      +---+---+---+      +---+---+---+

The first client will be located in the left column. When opening another window, this new window will be placed in the left column while moving the first window into the middle column. Once a row is full, another row above it will be created.

The number of columns is fixed and controlled by the value of nmaster of the tag. The number of rows is usually variable but you can set a minimum by setting ncol of the tag.

This sets the termfair layout on tag 7 of screen 1 and sets it to 3 columns and at least 2 rows:

awful.layout.set(vain.layout.termfair, tags[1][7])
awful.tag.setnmaster(3, tags[1][7])
awful.tag.setncol(2, tags[1][7])

browse

A very wide browser window is a pain. Some pages do restrict their width but others don't. The latter will be unreadable because your eye has to keep track of very long lines.

The browse layout has a fixed column on the left which is meant for the browser. Its size is controlled by mwfact of the tag. Additional windows will be opened in another column right to your browser. New windows are placed above old windows.

    (1)              (2)              (3)              (4)
+-----+---+      +-----+---+      +-----+---+      +-----+---+
|     |   |      |     |   |      |     | 3 |      |     | 4 |
|     |   |      |     |   |      |     |   |      |     +---+
|  1  |   |  ->  |  1  | 2 |  ->  |  1  +---+  ->  |  1  | 3 |
|     |   |      |     |   |      |     | 2 |      |     +---+
|     |   |      |     |   |      |     |   |      |     | 2 |
+-----+---+      +-----+---+      +-----+---+      +-----+---+

For my laptop, I place the right column on top of the browser column: Additional windows will overlap the browser window. This is unusual for a tiling layout but I need it: When browsing the web, I often want to open a terminal window (just for a few minutes, then I'll close it). Typically, the browser window would get resized and for most browsers this means that the current position in the web page is lost. Hence, I'd need to scroll the page to reach that point where I was before I opened the terminal. That's a mess.

Whether the slave column is place on top of the browser window or not is controlled by the value of ncol of the tag. A value of 1 means "overlapping slave column" and anything else means "don't overlap windows".

Thus, the following sets the browse layout on tag 7 of screen 1. The main column will have half of the screen width and there will be a separate column for slave windows.

awful.layout.set(vain.layout.browse, tags[1][7])
awful.tag.setmwfact(0.5, tags[1][2])
awful.tag.setncol(1, tags[1][7])
vain.layout.browse.extra_padding = 5

extra_padding reduces the size of the main window if "overlapping slave column" is activated. This allows you to see if there are any windows in your slave column.

gimp

Please note: Since Gimp 2.8, this layout is deprecated and no longer maintained. It may still work but I don't use it anymore. Gimp 2.8 has a "single window mode" which does all I need.

Gimp is something very special. A lot of people don't use Gimp because it has "so many windows". Using an own layout for Awesome, you can solve this "problem". (I don't consider it a problem, actually.)

The gimp layout uses one big slot for Gimp's image window. To the right, there's one slot for each toolbox or dock. Windows that are not Gimp windows are set to floating mode.

+-------+---+---+
|       |   |   |
| Image | T | D |
|       |   |   |
+-------+---+---+

By default (i.e., if ncol is 1), when opening another image window, it will be placed over the first window overlapping it. So usually, you only see one image window because that's the image you're working on. You can use an application switcher or hotkeys to switch to other image windows (see menu_clients_current_tags in the section "Utility functions").

Sometimes, you may need to get a better overview. By setting the value of ncol to 2, you can switch to "cascade mode":

+-------------+---+---+
|     +-----+ |   |   |
|     |     | |   |   |
|   +-| Img | |   |   |
|   | |     | |   |   |
| +-| +-----+ | T | D |
| | |     |   |   |   |
| | +-----+   |   |   |
| |     |     |   |   |
| +-----+     |   |   |
+-------------+---+---|

You can control the offset for each window by setting the global variable vain.layout.gimp.cascade_offset. The default value is 16 pixels.

When setting ncol to 2, all images will be stacked in the main slot:

+-------+---+---+
| Image |   |   |
+-------+   |   |
| Image | T | D |
+-------+   |   |
| Image |   |   |
+-------+---+---+

Again, mwfact controls the width of the main slot. So, the following will use the gimp layout on tag 7 of screen 1, defaulting to "stacking mode" and the main slot will have a width of 75% of your screen:

awful.layout.set(vain.layout.gimp, tags[1][7])
awful.tag.setmwfact(0.75, tags[1][2])
awful.tag.setncol(3, tags[1][7])

However, this is not enough. Default Awesome rules will set the toolboxes and docks to floating mode because they are utility windows. But: A layout doesn't manage floating windows. So we'll need a set of rules that set Gimp toolboxes back to normal mode. You have to merge this set of rules with your existing rules:

awful.rules.rules = awful.util.table.join(
    awful.rules.rules,
    vain.layout.gimp.rules
)

You can still use your own rules, for example, to move Gimp windows to a specific tag.

cascade

Cascade all windows (see gimp layout) of a tag.

Similarly, you can control the offsets by setting those two variables:

vain.layout.cascade.cascade_offset_x = 64
vain.layout.cascade.cascade_offset_y = 16

The following reserves space for 5 windows:

awful.tag.setnmaster(5, tags[s][1])

That is, no window will get resized upon the creation of a new window, unless there's more than 5 windows.

cascadebrowse

Similar to the regular browse layout, however, clients in the slave column are cascaded instead of tiled. Thus, there's a similar set of settings:

vain.layout.cascadebrowse.cascade_offset_x = 2
vain.layout.cascadebrowse.cascade_offset_y = 32
vain.layout.cascadebrowse.extra_padding = 5
awful.tag.setnmaster(5, tags[s][1])
awful.tag.setncol(1, tags[s][1])

I recommend setting cascade_offset_x to a very small value or even 0 to avoid wasting space.

See the browse layout for an explanation of extra_padding and ncol.

uselessfair and uselesstile

These are duplicates of the stock fair and tile layouts. However, I added "useless gaps" (see below). Use like this:

awful.layout.set(vain.layout.uselessfair, tags[1][7])

centerwork

You start with one window, centered horizontally:

+--------------------------+
|       +----------+       |
|       |          |       |
|       |          |       |
|       |          |       |
|       |   MAIN   |       |
|       |          |       |
|       |          |       |
|       |          |       |
|       |          |       |
|       +----------+       |
+--------------------------+

This is your main working window. You do most of the work right here. Sometimes, you may want to open up additional windows. They're put in the following four slots:

+--------------------------+
| +---+ +----------+ +---+ |
| |   | |          | |   | |
| | 0 | |          | | 1 | |
| |   | |          | |   | |
| +---+ |   MAIN   | +---+ |
| +---+ |          | +---+ |
| |   | |          | |   | |
| | 2 | |          | | 3 | |
| |   | |          | |   | |
| +---+ +----------+ +---+ |
+--------------------------+

Yes, the number "four" is fixed. In total, you can only have five open windows with this layout. Additional windows are not managed and set to floating mode. This is intentional.

Set the layout on one of your tags:

awful.layout.set(vain.layout.centerwork, tags[s][t])

You can set the order of the four auxiliary windows. This is the default configuration:

vain.layout.centerwork.top_left = 0
vain.layout.centerwork.top_right = 1
vain.layout.centerwork.bottom_left = 2
vain.layout.centerwork.bottom_right = 3

This means: The bottom left slot will be occupied by the third window (not counting the main window). Suppose you want your windows to appear in this order:

+--------------------------+
| +---+ +----------+ +---+ |
| |   | |          | |   | |
| | 3 | |          | | 0 | |
| |   | |          | |   | |
| +---+ |   MAIN   | +---+ |
| +---+ |          | +---+ |
| |   | |          | |   | |
| | 2 | |          | | 1 | |
| |   | |          | |   | |
| +---+ +----------+ +---+ |
+--------------------------+

This would require you to use these settings:

vain.layout.centerwork.top_left = 3
vain.layout.centerwork.top_right = 0
vain.layout.centerwork.bottom_left = 2
vain.layout.centerwork.bottom_right = 1

Please note: If you use Awesome's default configuration, navigation in this layout may be very confusing. How do you get from the main window to the window on the bottom left? This depends on the order in which the windows are opened! Thus, I suggest you use awful.client.focus.bydirection():

globalkeys = awful.util.table.join(
    awful.key({ modkey }, "j",
        function()
            awful.client.focus.bydirection("down")
            if client.focus then client.focus:raise() end
        end),
    awful.key({ modkey }, "k",
        function()
            awful.client.focus.bydirection("up")
            if client.focus then client.focus:raise() end
        end),
    awful.key({ modkey }, "h",
        function()
            awful.client.focus.bydirection("left")
            if client.focus then client.focus:raise() end
        end),
    awful.key({ modkey }, "l",
        function()
            awful.client.focus.bydirection("right")
            if client.focus then client.focus:raise() end
        end),
    -- ...
)

--> If you do this, you might want to change Standard program section (modkey -> altkey)

Useless gaps

Useless gaps are gaps between windows. They are "useless" because they serve no special purpose despite increasing overview. I find it easier to recognize window boundaries if windows are set apart a little bit.

The uselessfair layout, for example, looks like this:

+================+
#                #
#  +---+  +---+  #
#  | 1 |  |   |  #
#  +---+  |   |  #
#         | 3 |  #
#  +---+  |   |  #
#  | 2 |  |   |  #
#  +---+  +---+  #
#                #
+================+

All of my layouts provide useless gaps. To set the width of the gap, you'll have to extend your beautiful theme. There must be an item called useless_gap_width in the theme table. If it doesn't exist, the width will default to 0.

...
theme.useless_gap_width = "5"
...

Widgets

Each function returns a widget that can be used in wiboxes. Most widgets are updated periodically; see the code for the default timer values.

systemload

Show the current system load in a textbox. Read it directly from /proc/loadavg.

mysysload = vain.widgets.systemload()

A click on the widget will call htop in your terminal.

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 10 seconds.
.show_all: Show all three values (true) or only the first one (false)? Defaults to false.

cpuusage

Show the average CPU usage for a given amount of time. This is what htop does.

mycpuusage = vain.widgets.cpuusage()

A click on the widget will call htop in your terminal.

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 10 seconds.

memusage

Show used memory and total memory in MiB. Read from /proc/meminfo.

mymemusage = vain.widgets.memusage()

A click on the widget will call htop in your terminal.

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 10 seconds.
.show_swap: Show amount of used swap space? Defaults to false.

mailcheck

Check Maildirs and show the result in a textbox. For example, I have a set of Maildirs below ~/Mail:

$ pwd
/home/void/Mail
$ tree -ad
.
|-- bugs
|   |-- cur
|   |-- new
|   `-- tmp
|-- lists
|   |-- cur
|   |-- new
|   `-- tmp
|-- system
|   |-- cur
|   |-- new
|   `-- tmp
.
.
.

The mailcheck widget checks whether there are files in the new directories. To do so, it calls find. If there's new mail, the textbox will say something like "mail: bugs(3), system(1)", otherwise it says "no mail".

mymailcheck = vain.widgets.mailcheck()

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 30 seconds.
.mailpath: Path to your maildirs, defaults to ~/Mail.
.ignore_boxes: Another table which lists boxes (just the last part, like lists) to ignore. Defaults to an empty table.
.initial_update: Check for mail when starting Awesome (true) or wait for the first refresh timeout (false)? Defaults to true.

When clicking on the widget, the bash alias smail is called. That's a wrapper script for mutt which I use: It automatically commits to a git repository after I've read mail.

beautiful.mailcheck_new may contain a color. The new-mail-message is shown in this color. Uses red if undefined.

battery

Show the remaining time and capacity of your laptop battery, as well as the current wattage. Uses the /sys filesystem.

mybattery = vain.widgets.battery()

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 30 seconds.
.battery: Identifier of the battery to watch, defaults to BAT0.

volume

Show and control the current volume in a textbox. Periodically calls the control_volume script to get the current volume. That same script is used to set the volume. See below.

Left click: Mute/unmute.
Right click: Mute/unmute.
Middle click: Launch alsamixer in your terminal.
Scroll wheel: Increase/decrase volume.

myvolume = vain.widgets.volume()

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 2 seconds.
.mixer_channel: Defaults to Master.

I currently use a script similar to the following as control_volume:

#!/bin/bash
channel=${2:-Master}
case $1 in
	up)
		mpc volume +2
		;;
	down)
		mpc volume -2
		;;
	toggle)
		amixer set $channel toggle
		;;
	get)
		mpc volume | sed -r 's/^volume: ?([^%]+)%.*/\1/'

		echo -n ' '

		amixer get $channel |
		sed -rn 's/.*\[([a-z]+)\]/\1/p' |
		head -1
		;;
esac

That is, I get and set volume via mpd. I used to do all of that via amixer but this tool gets more and more broken. For example, once the volume reached 0%, amixer can't get it back.

This is a very ugly solution. I decided to use a wrapper script so I don't need to touch my Awesome configuration once I find a better solution.

mpd

Provides a set of imageboxes to control a running instance of mpd on your local host. Also provides controls similiar to the volume widget. To control mpd, mpc is used.

Right click on any icon: Mute/unmute via control_volume. See above.
Middle click on any icon: Call ncmpcpp in your terminal.

This function does not return one widget but a table of widgets. For now, you'll have to add them one for one to your wibox:

mpdtable = vain.widgets.mpd()
...
mywibox[s].widgets = {
    ...
    mpdtable[1],
    mpdtable[2],
    mpdtable[3],
    mpdtable[4],
    mpdtable[5],
    mpdtable[6],
    ...
}

The function takes a table as an optional argument. That table may contain:

.mixer_channel: Defaults to Master.
.show_label: Determines whether mpd: is shown in front of the control icons. Defaults to true.

net

Monitors network interfaces and shows current traffic in a textbox. If the interface is not present or if there's not enough data yet, you'll see wlan0: - or similar. Otherwise, the current traffic is shown in kilobytes per second as eth0: ↑(00,010.2), ↓(01,037.8) or similar.

neteth0 = vain.widgets.net()

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 2 seconds.
.iface: Defaults to eth0.

gitodo

This is an integration of gitodo into Awesome.

todolist = vain.widgets.gitodo()

The function takes a table as an optional argument. That table may contain:

.refresh_timeout: Defaults to 120 seconds.
.initial_update: Check for todo items when starting Awesome (true) or wait for the first refresh timeout (false)? Defaults to true.

beautiful.gitodo_normal is used as the color for non-outdated items, beautiful.gitodo_warning for those items close to their deadline and beautiful.gitodo_outdated is the color of outdated items.

borderbox

Creates a thin wibox at a position relative to another wibox. This allows you to create "separators" or "borders" for your wiboxes. For example, think of this as a wibox:

[======================]

If args.position = 'above', then you'll get an additional wibox below the existing one:

________________________
[======================]

It'll match position and size of the existing wibox.

If your main wiboxes are stored in a table called mywibox (one wibox for each screen) and are located at the bottom of your screen, then this adds a borderbox on top of them:

for s = 1, screen.count()
do
    -- Most likely, you'll want to do this as well:
    awful.screen.padding(screen[s], { bottom = 1 })

    -- Create the box and place it above the existing box.
    vain.widgets.borderbox(mywibox[s], s, { position = 'above' } )
end

borderbox() is defined as follows:

function borderbox(relbox, s, args)

relbox and s (a number) are required arguments, args is optional. args may contain:

.position: One of above, below, left and right. Defaults to above.
.color: The color of the additional box. Defaults to #FFFFFF.
.size: The size of the additional box, measured in pixels. Defaults to 1.

Utility functions

I'll only explain the more complex functions. See the source code for the others.

menu_clients_current_tags

Similar to awful.menu.clients(), but this menu only shows the clients of currently visible tags. Use it like this:

globalkeys = awful.util.table.join(
    ...
    awful.key({ "Mod1" }, "Tab", function()
        awful.menu.menu_keys.down = { "Down", "Alt_L", "Tab", "j" }
        awful.menu.menu_keys.up = { "Up", "k" }
        vain.util.menu_clients_current_tags({ width = 350 }, { keygrabber = true })
    end),
    ...

magnify_client

Set a client to floating and resize it in the same way the "magnifier" layout does it. Place it on the "current" screen (derived from the mouse position). This allows you to magnify any client you wish, regardless of the currently used layout. Use it with a client keybinding like this:

clientkeys = awful.util.table.join(
	...
	awful.key({ modkey, "Control" }, "m", vain.util.magnify_client),
	...
)

If you want to "de-magnify" it, just reset the clients floating state to false (hit Mod+CTRL+Space, for example).

Window borders colored according to nice values

By default, your rc.lua contains something like this:

client.add_signal("focus", function(c) c.border_color = beautiful.border_focus end)
client.add_signal("unfocus", function(c) c.border_color = beautiful.border_normal end)

You can change it to this:

client.add_signal("focus", vain.util.niceborder_focus)
client.add_signal("unfocus", vain.util.niceborder_unfocus)

Now, when a client is focused or unfocused, Awesome will look up its nice value in /proc/<pid>/stat. If it's less than 0, this window is classified as "high priority"; if it's greater than 0, the window is classified as "low priority". If it's equal to 0, nothing special happens.

This requires to define additional colors in your theme.lua. This is what I use:

theme.border_focus_highprio  = "#FF0000"
theme.border_normal_highprio = "#A03333"

theme.border_focus_lowprio   = "#3333FF"
theme.border_normal_lowprio  = "#333366"

tag_view{next,prev}_nonempty

Maybe you're using a taglist that shows only non-empty tags:

mytaglist = awful.widget.taglist(s, awful.widget.taglist.label.noempty, mytaglist.buttons)
--                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Now, the default setup looks something like this:

globalkeys = awful.util.table.join(
	-- Standard navigation
	awful.key({ modkey }, "Left",   awful.tag.viewprev),
	awful.key({ modkey }, "Right",  awful.tag.viewnext),
	...

So when pressing modkey + right, you jump to the next tag. However, when only showing non-empty tags, the target tag may be empty! I don't like that. I always want to jump to the next non-empty tag.

tag_viewnext_nonempty() and tag_viewprev_nonempty() do exactly this. How to use them:

globalkeys = awful.util.table.join(
	-- Standard navigation
	awful.key({ modkey }, "Left",   vain.util.tag_viewprev_nonempty),
	awful.key({ modkey }, "Right",  vain.util.tag_viewnext_nonempty),
	...

Note: To jump to an empty tag, you now must address it directly. That is, press modkey + 4 or similar.
