Rules refactor, part 1
This fix the following awful.rules bugs:
* **x**: Broken when "border_width" is set or left titlebars are used
* **y**: Borken when"border_width" is set or top titlebars are used
* **width**: See above + right litlebar
* **height**: Same as above
* **switchtotag**: Have a race with the "manage" -> "tag.withcurrent" code in `awful.tag`
* **tag**: Had dead code
* **screen**: Had a race condition with switchtotag
* **urgent**: Had a race with screen and another with switchtotag+focus
* **focusable**: Was broken yet again when request::activate was introduced (and also because of FS1098, that I also fixed)
* **no_overlap**: The "no_overlap" call in rc.lua "manage" section conflict with the geometry rules as the hints are not set (idk why).
* **size_hints_honor**: If set to false, it would be applied too late, causing height and width offsets due to placement or various geometry related properties
Remove request::fullscreen and request::maximized_* and use
a single request for them. The other client resizing features
will soon also start to use this.
Due to recent changes, it was no longer possible to disable the
default tag selection handler. This commit extend the already
existing request::tag mechanism to let handlers select the tags.
There was a regression when refactoring the API. It was no longer
possible to disable the automatic tag selection.
Due to recent changes, it was no longer possible to disable the
default tag selection handler. This commit extend the already
existing request::tag mechanism to let handlers select the tags.
Testing demonstrated that many rule properties were broken when used
together. This commit try to address this by forcing an execution order
that doesn't trigger the problems.
It is still possible to write broken rules, but it should not happen by
accident anymore. Users should not try to assign the client a tag on
screen 2 and also use screen=screen[1].
This commit also add a 3 step process to apply rules.
Testing showed that many rules are currently broken because
of execution races.
Create a new dynamic tag for the client.
There was many unfixable race conditions that could only be
solved by better integrating the request:: system and
awful.rules. This has the side effect to make rules mandatory.
In the case where one want to put the cursor at the middle of the
workarea, it is logic to do:
x=screen.workarea.x+screen.workasrea.width/2
However, this can cause floating points. This commit move the
burden back to the C-API so the Lua placement code doesn't have
to add a large number of rounding methods. Given 1 type of rounding
cover a vast majority of use cases for each types of coordinates,
the C-API can take care of it in peace. For the other corner cases,
it is still possible for the Lua code to do the rounding there, but
no longer necessary. The convenstions are:
'x' and 'y': use round (move to the closest point)
'width' and 'height': use ceil (to avoid involontary truncating)
This change catches things like c:geometry { width = -42 }.
