The goal is to catch cases where the return value exists, but is
forgotten. There was a large enough number of them to turn this
into a real check. Initially, I just wanted to implement it to fix
the problems, then delete the code. But since this is so common, I
think it is worth the annoyance.
The newly changed code doesn't handle this well:
local w = wibox.widget {
{
--add anything here
widget = wibox.layout.fixed.horizontal
},
widget = wibox.layout.fixed.horizontal,
}
This will cause the "inner" fixed layout to have the minimum size
it supports. In that case, if the last widget has "no size" because
it supports up to 0x0, then it isn't added to the layout.
This was done "on purpose" because if there is a spacing, then `:fit`
would have returned a size "too small" because the last spacing area
would be (correctly) missing.
But if the zero sized widget isn't added to the layout, then it's size
isn't tracker. So if it emits a layout_changed signal, nothing catches
it.
The "fix" is rather hacky and probably a little incorrect. It rely
on the behavior of `:fit()` to avoid adding the "wrong" widgets to
the layout, which is fragile.
However, I don't have a better idea.
Add an explicite `@property` tag to the `wibox.layout.flex` doc
comments to override the `fill_space` property from
`wibox.layout.fixed` and mark it as hidden thanks to `@hidden`.
For each widget, the layout function checks whether placing it would
make the function exceed the allowed geometry.
If not, the function places both the widget and a spacing widget.
This check ignores the size of the spacing widget itself, this can cause
overloading of widgets on top of each other.
For example, the following scenario with these widgets:
widgets: widget1 { width = 10, height = 10 }
widget2 { width = 10, height = 10 }
widget3 { width = 10, height = 10 }
and a call to horizontal layout with the
{ width = 10, height = 10, spacing = -5 } parameters.
The function would layout the widgets the following way:
{
widget1: { x = 0, y = 0, width = 10, height = 10 }
spacing: { x = 5, y = 0, width = 5, height = 10 }
widget2: { x = 5, y = 0, width = 5, height = 10 }
spacing: { x = 5, y = 0, width = 5, height = 10 }
widget3: { x = 5, y = 0, width = 5, height = 10 }
}
This behaviour would be the same for any number of widgets for negative
layout.
This patch changes the layout function to check whether the current
widget uses up the whole space.
It also removes 'pos' variable. Its purpose isn't intuitive in the
presence of x and y. This helps to understand where each widget is
placed now that x, y don't hold the end location of the widget in the
previous loop iteration.
The result of the previous example becomes:
{
widget1: { x = 0, y = 0, width = 10, height = 10 }
}
While this might not be the wanted behaviour exactly, distinguishing
between the scenario where 2 widgets are drawn and a scenario where 3
are drawn might complicate the layout function too much.
This patch also adds unit testing that catches the described behaviour.

The fit function is called twice in row.
- The first time it gets the maximum available width, and returns how
much of it it needs (with 0 spacing it would be 477)
- The second time the available width it gets is the same as it returned
last phase (and probably is expected to return the same result again)
The width fit requests is the total width of all widgets together + the
spacing (e.g. if each tag widget is 53 px and spacing is -10 then the
requested width 53 * 9 - 80).
The function tries to first fit all its widgets (the tag numbers) in the
amount of width it received, and only then adds the spacing to it. This
is problematic because in the second phase the widgets need to fit
themselves in the same width they requested earlier minus the spacing
(in case of negative spacing). This is of course impossible and so some
widgets are just not being drawn correctly.
This patch makes fit function take into account the spacing while
placing the widgets and not afterwards.
Also add unit-testing that test the bug described.

The function has several expressions of the form
if self._private.dir == "y" then
This patch stores the result of
self._private.dir == "y"
to avoid code duplication.
Also remove the 'used_in_dir' and 'in_dir' variables since their values
can be calculated using other variables in the function and updating
them individually is error prone.
This patch doesn't do any functional changes.

There seem to be two issues here. First, the if-statement at the
beginning of the function will return prematurely if
`self._private.widgets[index]` exists. There seems to be a
missing `not` there.
Second, index 1 is interpreted as the top of the stack (although the
documentation says otherwise), but the widget is inserted at the end of
`self._private.widgets`, so it gets pushed to the bottom
instead of the top.
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
It is not possible to distribute 100px to three widgets equally. The
current version of wibox.layout.flex tries to do that anyway, by giving
each widget 33px and leaving one pixel outside of any widget. Thus, if
the widgets e.g. have a common background, this leads to a one pixel gap
in the background.
This patch changes the flex layout so that the extra pixel is assigned
to some widget instead. It does so by basically keeping a sum of
space_per_item for the widgets that was assigned so far. This sum is
rounded and when this leads to rounding, the corresponding child widget
gets an extra pixel.
More precisely, this tracks a pos as before. Widgets get their position
still assigned based on rounding pos. However, this now also remembers
this rounded position for the next iteration of the loop. This allows to
assign the size of widgets based on the difference between the current
and last rounded position.

The ratio, fixed and flex layout can now display a widget between
each layout elements.
The align layout was left out because it doesn't support spacing
This allows, for example, to imeplement the tag `master_fill_policy`
and simplify the client layouts by not having to hardcode empty
columns and rows in each layouts.
Most of the entries that are marked as "TODO: Get rid of these" were
handled. wibox.layout.align:get_children() never worked (it always
called a non-existent function), so we can easily fix this entry without
introducing a regression.
I opened https://github.com/awesomeWM/awesome/issues/1672 to track the
underlying problem behind the broken :get_children() function (which is
missing test coverage).
