This function updates a hierarchy if the layout of some widgets changed. It does
nothing on the parts that did not change. This should be more efficient than
recomputing the whole hierarchy whenever something changes.
Once again, this has some positive results on the "benchmark test":
Before:
create wibox: 0.083016 sec/iter ( 13 iters, 1.161 sec for benchmark)
update textclock: 0.00391091 sec/iter (271 iters, 3.219 sec for benchmark)
relayout textclock: 0.00273234 sec/iter (397 iters, 1.087 sec for benchmark)
redraw textclock: 0.0010191 sec/iter (989 iters, 1.745 sec for benchmark)
After:
create wibox: 0.083146 sec/iter ( 13 iters, 1.163 sec for benchmark)
update textclock: 0.00170519 sec/iter (647 iters, 2.201 sec for benchmark)
relayout textclock: 0.000581637 sec/iter (1880 iters, 1.094 sec for benchmark)
redraw textclock: 0.0010167 sec/iter (997 iters, 1.773 sec for benchmark)
So again no difference for creating wiboxes (100.16% compared to before). This
time we also have no real difference for creating wiboxes (99.76%). Update (44%)
and relayout (21%) are improved a lot.

This makes the textbox' :draw() and :fit() callbacks use the DPI that is
specified in the given drawing context. With this, the textbox now scales
correctly if different screens have different DPI values.

This has some positive results on the "benchmark test". Each single number is
the best one out of three runs.
Before:
create wibox: 0.0826502 sec/iter ( 13 iters, 1.157 sec for benchmark)
update textclock: 0.0186952 sec/iter ( 57 iters, 2.473 sec for benchmark)
relayout textclock: 0.0158112 sec/iter ( 64 iters, 1.028 sec for benchmark)
redraw textclock: 0.0015197 sec/iter (662 iters, 1.861 sec for benchmark)
After:
create wibox: 0.0825672 sec/iter ( 13 iters, 1.154 sec for benchmark)
update textclock: 0.00378412 sec/iter (277 iters, 4.216 sec for benchmark)
relayout textclock: 0.00259056 sec/iter (420 iters, 1.09 sec for benchmark)
redraw textclock: 0.00105128 sec/iter (958 iters, 1.79 sec for benchmark)
We see no significant change in the creation of wiboxes (99.9% compared to
before). Update (20% of the previous run time), relayout (16%) and redraw (69%)
are all sped up by this change.

Before this, dependencies between widgets where implicitly discovered by
recursive calls to base.fit_widget() and base.layout_widget(). However, it is
too easy to get this wrong (just call one of these functions from outside of a
widget's :fit() / :layout() function) and the resulting mess would be hard to
debug.
Thus, this commit changes the API so that callers have to identify themselves
and we can explicitly record the dependency between the widgets involved.
This also fixes a bug where no dependencies were tracked for widgets after
:set_visible(false). Whoops...
Sorry for breaking the API for adding this.

This is used by `tooltip.place` then to tie the tooltip to the screen of
the mouse. Without this, a tooltip from the tasklist might get moved to
the screen above the tasklist, if it gets considered to be on that
screen given its coordinates.
Closes https://github.com/awesomeWM/awesome/pull/437.
When a complete repaint is scheduled, also do a relayout, because this is also
the case that we go through when the underlying cairo surface is resized. For
example, resizing a client with a titlebar would trigger this.
Also, going through this code path is necessary since this is the only place
where the dirty area is updated so that it includes "everything". Before this
change, nothing was actually redrawn, because the dirty area was empty.

Extend the range of the 'group_names' patterns which is currently
restricted to typical ones like
pc+us+ru:2+de:3+ba:4+inet
to more general ones such as
macintosh_vndr/apple(alukbd)+macintosh_vndr/jp(usmac)+macintosh_vndr/jp(mac):2

returned by awesome.xkb_get_layout_group().
This accidentally called the draw callbacks with a nil argument instead of the

The default config has this:
awful.key({ modkey, }, "o", awful.client.movetoscreen ),
This moves the client to the next screen and focuses that screen.
But it does not ensure that the client is raised above any existing
windows, e.g. when moving a floating client.
This patch emits the `request::activate` signal if the client is
currently focused, but only if the screen property actually has changed.

These caches, well, cache the result of the :layout and :fit callbacks on
widgets.
Clearing caches is done by recording dependencies between a widget. When a call
to base.fit_widget() or base.layout_widget() recursively causes another call to
such a function, this means that the earlier widget depends on the later widget.
This dependency is recorded and when the later widget emits
widget::layout_changed, the caches of all the widgets involved are cleared.

This new function spawns a program, similarly to awful.spawn, but captures its
output. On each line of output on stdout / stderr, a Lua function is called with
this line. There are different callbacks for stdout and stderr. When both stdout
and stderr are closed, another callback function is called. The intention for
this last callback is "the program is done", because most programs should only
close their output when they exit.

After this change, fit_widget() enforces that a widget cannot ask for more space

In expand nodes "none" and "outside", the variable size_remains describes how
much space is available for the first/third widget. Everything else is used by
the second widget. Thus, fitting the second widget to anything involving
size_remains is wrong. Instead, this commit uses the correct value.
This also fixes a messed up argument order for horizontal align layouts.

The tooltip might be partly outside of the screen, and especially the
workarea, e.g. for tooltips on the tasklist.
Calling `awful.placement.no_offscreen` makes sure that it is fully
inside, and will even restrict it to the workarea, not only to the screen.

This adds gears.timer.start(timeout, callback) that creates a timer object and
connects a callback to it, all in one go.
Additionally, this adds gears.timer.weak_start(timeout, callback). The weak
version still allows the callback function to be garbage collected and will then
stop the timer.
This was tested with the following code:
require("gears.timer").start(0.3, function()
print("ping")
if collectgarbage("step", 500) then
print("collection done")
error("err")
end
return true end)
require("gears.timer").weak_start(0.1, function()
io.stdout:write(".")
return true
end)
After a full collection cycle, both timers are stopped. The first one is stopped
because of the error() that it generated. The second one is stopped because the
callback function was garbage collected.

Given an outcome of e.g. 1.01 its more sane to use 1 than 2, especially

Because of `placement.under_mouse` (and without
`placement.no_offscreen` fixing it), this will cause the tooltip to hide
immediately again.
There is no need for hooking into this signal, but this adds a click
handler to close the tooltip when clicking into it.
This splits the logic for `delay_show` out of `show`/`hide`, and handles
an already stopped timer. The timer gets also stopped after the tooltip
has been displayed.

Use `beautiful.xresources.apply_dpi` for `common.list_update`'s textbox
margins, and add a left margin for the imagebox, too.
The latter is useful/nicer with the default behavior of an inverted
style for the focused tasklist entry.
18f6ab1 changed the behavior when resizing floating clients using the
mouse (via modkey + RMB).
Previously, you could initiate the mousegrabber using e.g. "modkey +
RMB", release the key and button, and resize the window using the left
mouse button.
This restores this behavior by canceling the mousegrabbers only if the
cursor was moved, without _any_ mouse button being pressed.

Instead of `client.client`, the client object is now referred to as

This adds a `stacked` boolean argument to `awful.client.visible`, and
(relevant) callers of it.

This adds an optional screen argument to get_dpi/apply_dpi and set_dpi
to store DPI values per screen.
This can be used in your config to manage different DPI values for an
internal and external display:
beautiful.xresources.set_dpi(125, 1)
beautiful.xresources.set_dpi(94, 2)
This is meant to be the foundation for more evolved DPI handling in
awesome.

color_strip_alpha was used to insert colors into Pango markup, but it
did not correctly check for valid Pango colors. ensure_pango_color
checks if the color is valid in Pango, and returns a placeholder if it

In ed09d8e this was changed accidentally, while only `request::focus`
should have been changed:
- c:emit_signal('request::activate',"rules")
+ c:emit_signal('request::activate', "rules", false)
Currently `taglist_update` gets triggered often, because it listens to
a lot of signals.
This patch makes it only call the last one through `timer.delayed_call`.
Currently `tasklist_update` gets triggered often, because it listens to

This patch makes it only call the last one through `timer.delayed_call`.
In #152 I've changed the autofocus handler to emit the request::activate
signal, instead of setting client.focus only.
This is wrong IMHO, and can be annoying:
If you have two floating clients above a tiled / maximized one, and
close one of the floating ones, with the tiled one being the one
selected by autofocus, it will be raised above the other floating
client.
This is changed now to use the new `request::focus` signal instead.
This basically reverts 20cdb5d (#152), but allows for customizing this
behavior, by overriding the default `request::focus` handler
(`ewmh.focus`).
It would be nice if there was a helper to check if a window's content
isn't visible at all (i.e. covered by other windows), and that could be
used then by the (new) default handler for request::focus - raising the
client only, if it's completely covered by another window.
Fixes https://github.com/awesomeWM/awesome/issues/217
This still does `client.focus = c` by default, but allows to customize
it.
This was initially suggested in #194, but by using `request::activate`
instead, which would not be the same. Therefore a new signal is being
used instead.

This way "that other widget" doesn't prevent the current widget from being
garbage collected.
Please note that this in all of these cases the widget under consideration does
have a strong reference to the callback function. This means that the callback
cannot be garbage collected until "this widget" itself is collected. Thanks to
this, this change is safe.

In commit 3cbdc2a79f, the argument order for awful.layout.inc was changed
from (layouts, i, s) to (i, s, layouts), so that layouts can become an optional

To hide this breakage, we assume the old argument order if the number i is a
