Another step in moving these APIs toward the common object oriented and
declarative paradigms used by other APIs.
This commit introduces the `awful.keyboard` module. It currenly only
exists as a placeholder for the first few append/remove function, but
will grow in scope in another pull request to expose the currently
private modifier APIs and to provide keybindings collision detection
and replace some of `awful.hotkey_popup` business logic.
The `keygrabber` tests which uses root keybindings are disabled for
now to keep the commit size small. This is necessary since the shims
will need many iterations of changes before this work again with the
new syntax.
It might not be the most pretty of change, but it works. With this
change, it is possible to have multiple "things" in the "same"
section having the "same" name.
This allows for C/C++ style functions with the same name but different
signatures. Lua doesn't handle this well, so it should usually be
avoided. However, constructors might be a valid exception. Most older
widget (and object) constructors have multiple random argument while
newer one use `args`. Deprecating the old ones for the sake of
standardization might be a bit too much for users upgrading from v3.5.
Given the only reason all of those deprecation would happen is because
"its pretty that way", then lets allow 2 constructors and avoid outrage.
The fix focuses on ewmh.merge_maximization function, which handles client intentions to change maximization states.
The fix includes:
1. Fixing the `get_value` helper function to return the proper resulting state that client wanted to change.
For example, when `c.maximized and not c.maximized_horizontal and not c.maximized_vertical` holds,
the client would observe the `MAXIMIZED_VERT` and `MAXIMIZED_HORZ` atoms in X11, but get_value would compute
the result values based on `c.maximized_{horizontal,vertical}`, which are all false. The fix makes the computation
consistent to clients' view.
2. Interpret a client's maximization intentions based on the client's view of how the X11 atoms changes.
Having buttons without an awful.util.table.join/gears.table.join
has never been officially documented to be supported. I hope there
isn't too many of those and they wont try to mix the new and old
API syntax, because that will totally break.
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.
There is no better place to put it and need to always be required
for backward compatibility. Given Awesome no longer works properly
without `awful`, I put the code there.
The reason for this is that as more of CAPI is brought in line with the
current API guidelines, it is more and more likely the tests will hit
APIs shims (either to test them or because the prototype remains the
same and only the implementation moved to Lua).
The use case for this will be to detech which screen is connected to
an output from the screen rules.
It is in millimeters because this is what the output provides and in
inches because the DPI is based on that unit and screens are sold with
the size in inches on the box.
Identical viewports are already handled before getting into Lua,
but sometime xrandr gives another viewport that encompass all
others. It has to be removed.
When the screens are created from the viewport in Lua, the signal is
sent too early and the DPI and outputs have not yet been added. This
cause the `connect_for_each_screen` callbacks to be called with a
partially initialized screen object. It also causes the drawables to be
repainted too early.
CAPI now emits "_added" and "awful.screen" takes care of emitting
"added".
With this, there is plenty of palces where the DPI can be set before
those signals are sent. This allows wallpaper with the proper DPI to
work with screens created using `fake_add`. In turn, this will allow
screen rules to control the DPI. In "the past", the DPI used for those
handler was the native DPI of the screen with no opportunity to change
it before hand.
This is easier than messing with the `fake_resize()` method. This will
eventually have an awful.screen.rules equivalent to auto-split the
screen from the rules.
This doesn't mean removing all screens is supported. It isn't and never
will be. The only reason this commit exist is to allow some
initialization and error handling code to be tested.
Add `dpi.lua` to config.ld even if it isn't added yet. This is
because the way the test run has it cached in the build dir. A full
rebuild would take too long and timeout on travis for semi-large PRs.
Technically this doesn't solve any memory leak, but AwesomeWM uses in
average less memory when changing the selected tab in quick succession.
This is because it has less "temporary" tables to track.
Some titlebar widgets (`awful.titlebar.widget.titlewidget`,
`awful.titlebar.widget.button` and other specific button widgets) could
not be garbage collected until the associated client was unmanaged,
because the signal connection used to update the widget was never
destroyed, and the signal handling function was keeping a reference to
the widget in its environment. This resulted in high memory usage when
the titlebar widgets were recreated multiple times for the same client
(this does not happen with the default Awesome configuration, but may be
needed for dynamic titlebar reconfiguration in a custom config).
Modify the code to use weak tables instead of direct signal connections
to avoid keeping strong references to widgets. The widget update
functions still keep strong references to the widget itself (creating a
reference loop, but the Lua GC should handle it correctly) and the
client object, but this should not be a problem.
One publicly visible change is that `awful.titlebar.widget.titlewidget`
now has an `update` function, like the button widgets.
