There is already a hack into `awful.widget.common`. This system aim
to make the hack obselete while preserving the useful part.
I think this is also necessary to properly support SVG (with DPI
and resize).
Finally, Qt handle this using the QBrush concept, where you can have
programmatic patterns. Cairo doesn't have this concept, so there is no
"clean" way to have programmatic brushes.
It's unused since commit 0aa4304bda. Before this was a stable sorting
algorithm since table.sort is allowed to be unstable. Apparently we don't need a
stable sorting algorithm anymore.

Any awful.titlebar.widget.button widget (e.g. floatingbutton or closebutton)
decides on the currently visible symbol based on several factors. One of them is
"is the client currently focused?" and thus the button has to be updated when
the client is focused/unfocused.
The way the code did this was to use client.connect_signal("focus", f) and
client.connect_signal("unfocus", f). However, these signals are never
disconnected and kept alive forever. The callback function had a strong
reference to the client (as an upvalue) and thus this also prevented the client
from being garbage collected.
Fix this by using c:connect_signal("focus/unfocis", f) instead. These kind of
signals are only kept alive by the client object and don't prevent it from being
garbage collected.
This fixes the new test that the previous commit added.

Until now, this layout was "append only". There was no official
APIs to remove, replace, insert and swap widgets. This is fine
for the usual wibox + sensors widget used by the majority of
users, but lack flexibility necessary to use the layout system
to place dynamic elements such as clients.
The methods introduced by this commit are also recursive. This
allow widgets to be decorated, wrapped and splitted without
having to add boilerplate code everywhere.
This remove duplicated code and will allow more "collection"
style layouts to be implemented without logic duplication.
This commit also do some small cleanup to remove duplicated
code now present in `awful.util`.

Go around a limitation of the lua language spec. The return value
of this method guaranteed `ipairs()` correctness.
Please note that both the official Lua and Luajit implementation
provide a sparse table compatible `ipairs()` and __len implementation
by default.
It is an internal API and is used by `gears.shape`, `gears.pattern`
and `gears.composition` only.
This commit also add `:rotate_at` and `:copy` methods.
It is necessary to have it beforehand when creating layout objects
for unselected layouts.
In the current layout system, there is no layout object, but to allow
tabs and dynamic tagging features like ion3, layouts cannot be stateless.
Before, it was the caller job to make sure the client wasn't floating.
This limitation is unecessary. awful.client.idx now return nil instead
of an error. awful.rules setting the master width factor are now
foolproof.
This code is imported from Elv13 config and make it very easy
to create shaped objects.
If accepted upstream, other shapes, such as arrow and powerline
will also be added. This commit introsuce the 2 most common
shapes, rounded rectangle and rounded bar.
This allow the most basic kind of stateful layouts to be created.
It is now possible to have layout instances instead of global
stateless layout arrange functions.
This allow layout "arrange" to be called less often and react on
the cause of the change itself rather than it's consequences
(usually, the "focus" signal).
Previously, the layout were re-arranged everytime the focus changed.
Now, with "raised" and "lowered", it require less "arrange".
"swapped" allow smarted layouts. Currently, swapped cause a full
re-arrange. It re-read the "index" list from scratch and create
a "new" layout. With "swapped", incremental layout changes are
possible.

gears.surface now returns a fallback image surface that is good enough for what

Instead of throwing a Lua error, the code now just prints an error message to
stderr on invalid markup. For callers which want to handle this case specially,
we add :set_markup_silently() which returns error messages.

This adds support to gears.color.parse_color to parse things like "#fff" (one
character per color component, without alpha) and "#ffff0000ffff0000" (four
characters per component, with alpha).
This makes sense on its own, but should also help with

*WARNING* This introduce a minor API break as awful.tag.setscreen
arguments are now swapped for consistency
This allow to introduce logic for each properties and improve
awful.tag.add and execute logic when setting properties.
The code here doesn't always work, so it's best to just don't mess with
awesome.version, but return it directly.

Previously, a Lua error was thrown when loading a file failed. Most callers are
not prepared for this and the result is less than optimal.
This commit makes the functions print the errors and return nil instead. For
callers that want to handle errors themselves, "_silent" variants of the
functions are introduced which just return errors to the caller.

Having many arguments can easily get confusing and hard to understand. This

This adds functions for getting directories according to the XDG base dir
specification. This might be useful in general.
This also adds a function for getting the cache dir, because I like an explicit
function call more than something which "switches" based on a string argument.
Better error messages if you mis-type something. :-)
Finally, this adds a function for getting the directory containing the rc.lua
file. Sadly, awful.util.getdir("config") did not actually do that. See #218.

Without this fix `wibox.widget.textbox` ignores current theme font
setting and resets it to the initial one.
It becomes handy when the initial theme is tweaked during runtime, ie.
in `rc.lua`. Other AwesomeWM components like `awful` (taglist,
tasklist, menu) are aware and do respect the actual theme settings.

Lua will remove objects as values from a weak table before these objects are
finalized, but as values only in the next garbage collection cycle after the
object was finalized. Up to now, gears.object uses a table with weak keys so
that :disconnect_signal() works. This means that a signal can still call methods
which were already considered garbage by the garbage collector and thus can use
userdata from the C side which was already finalized. Crashes and other bugs
result.
This commit changes the code so that the function is also a value in the weak
table. Thus, the GC will remove the entry before the object is finalized.
Special magic is needed for Lua 5.1, because there only userdata has the
behavior that we want while we have a function. We do some magic with function
environments to make this work...

When emitting layout_changed, the widget is relayouted. If this doesn't actually
change anything, nothing will be redrawn. Thus, this also emits redraw_needed to
force redraws.
This fixes a race condition with some weird tray icons. A new tray icon is
created and the systray is updated. Then this new icon is destroyed immediately
again and at the same time another icon is created. Then, the systray isn't
updated since the number of icons (=the layout) did not actually change.
However, it needs to be updated and so we ended up with broken/missing icons.
