get_children's return value should not be called "The". That was a
mistake because ldoc requires a name for return values and parameters.
If a name isn't provided, it thinks the first word of the description
is the name.
Now always call both check_widget and make_widget_from_value. This
should make it a lot less confusing when randomly trying to create
a widget as all ways to do it slowly converge toward an unified
one.
ldoc has a magical `@classmod` module type which tries to detect
what is a method and what is a static function. It fails about as
often as it works. This commit makes everything explicit to remove
such issues.
Fixes#2640
Ref #1373
* Move table functions out of awful.util into new gears.table
* travis: Use v9999 prefix for full requests
Make sure no newly deprecated functions are used
* Move all `awful.util.table.*` calls to `gears.table.*` calls
Move table test functions from awful/util_spec to new gears/table_spec
Change awful.util.subsets call to gears.math.subsets in awful/key.lua
It should be called "align", but the name is already taken
It doesn't use awful.placement because it would break the dependency
graph.
Some cases previously required 2 wibox.layout.align layouts,
one for each axis. This is massively overkill to simply place
a widget at the center of a larger area.
