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.
This commit add an optional `--screen off` command to initialize Lua
without first adding the screens. This is inconvinient for most users
since it restrict the APIs that are usable out of the box.
However, this allows AwesomeWM to work independently from the hardware.
This means that when a screen is unplugged, it is the Lua code that will
remove the screen instead of CAPI pulling the carpet from under. It also
allows to ignore some screen areas before the screen is ever created.
Combined, it makes it possible to work with screens even when they are
physically disconnected. Finally, it will allow for an awful.rules like
API to control how screens are created.
All in all, some people need this for their setup and some people might
want to do it anyway for fine grained and/or dynamaic multi-screen
setups.
This commit also adds 4 new signals to `capi` to be able to
execute code at specific points during the initialization. The commit
improves naughty error notifications to work even if problems occurs
before the screens are added.
Note that AwesomeWM will exit if no screens are created. While it would
be easy to just call `refresh_screen();` after unsetting the magic
variable, doing so would have corner cases. Better be harsher and
prevent the user from shooting themselves in the foot from not reading
the f****** manual. Code introduced in future commits will take care
of automatically calling fake_screen in the event nothing is created.
Fixes#1382
This function allows to update the content of a table using the
content of a second table. It helps to keep the original reference
and to know what has been added and removed.
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.
This code is inside an "if new_timeout and [something else]". Thus, it
only executes when new_timeout is "truthy". Thus, "new_timeout or
[whatever]" will always evaluate to "new_timeout".
This commit removes that tiny bit of dead code.

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.
The way background are rendered changed to accomodate issues regarding
cliping and border. However this broke the documentation examples.
This commit fixes this in the least hacky way I found.
Fixes#2727
Nobody wants to set this parameter. It is necessary because the old
API allowed `awful.rules` to be used with random for random matching.
This stopped "really" working between the 3.4 and 3.5 release because
the code started to accumulate "corner case" fixes aligned with the
client properties. v4.0 added more ordering and v4.3 added external
sources. After this, it is unusable with external objects, but
`gears.matcher` handle this use case very well.
In a perfect world we would have pure expression matching, but
that's problematic with all the "metaness" of the code. For now,
this adds an imperfect way to match the minimum and maximum of
number properties.
It will be used by the screen rules for the DPI and size properties.
This is hardcoded in `awful.rules`, but cannot be shared due to the
priority corner cases. Given in the long run any "standard" priority
should use the topological sort API, better not try to share *that*
code.
It is now possible to add and remove rules. This is superior to how
`awful.rules` originally handled rules because modules can now
assume adding and removing rules works.
The reason for the methods rather than `table.insert` is partially
because future commits will add signals. In turn, this will allow
`gears.matcher` to be extended by module using it using the extra
"introspection" made possible by the signals.
The name is self explanatory, it adds more actions to a notification.
One of the use case is adding a snooze/reming_me action. Another one
is "mute similar notifications".
The reason is that if actions are provided by rules, only one instance
exist. It was a mistake to couple actions with their notifications. It
could not work reliably and has to be removed.
The commit also change the notification action storage to be a copy
instead of the original table. This allows to append actions (not part
of this commit) without risking adding them to the wrong notification.
**WARNING** This break an unreleased API by removing the `notification`
property of an action.
* app_name: To be used in filters when no clients are found.
* max_width: Allow to set it from the rules, it might be different
when a `widget_template` is used.
* widget_template: Now it can be set from the rules without further
boilerplate code.
The old preset code had a primitive implementation of the rule API
used in `naughty.dbus`. Now that `gears.matcher` is extracted from
`awful.rules`, it is possible to share the code.
The first step is to only enable the old API when the new
`request::preset` isn't connected. This is the same way the legacy
popup is only enabled when nothing is connected to `request::display`.
This removes the imperative "mutex" logic from rc.lua, where it doesn't
belong. It also makes it closer to the "vision" of making `rc.lua` fully
modular.
* action icons
* persistence
* residence
* categories
* animated icons

In addition, the commit also tries its best to attach notifications to
objects using various dubious semi compliant hints or the DBus PID. It
works often enough to be useful.
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.

This is needed because if async code is run inside of a tooltip timer func the started property may not still be false.
The current version causes random spurious timer already started errors.
This is configurable globally or per-notification. When it is
replaced over dbus, it has a new timeout and *that* should be the
new timeout (starting when the notification is replaced).
Closes#2821
The awful.placement.no_overlap function always looked at the currently
visible clients when placing a new client. This produced a confusing
result when using awful.rules or the sn_rules argument of awful.spawn to
place the client on an unselected tag (the client was placed as if it
would be placed on a currently selected tag; if multiple clients were
placed on the same unselected tag, in many cases they were placed at the
same position, overlapping each other).
Make awful.placement.no_overlap check tags of the placed client and
handle the case of placement on an unselected tag in a more useful way:
- If the client is sticky or at least one of the client tags is
selected, keep the previous behavior: avoid overlap with all other
floating clients which are currently visible, and use the currently
active layout to determine the floating status.
An explicit check based on `c:tags()` is made instead of using
`c:isvisible()`, so that the previous behavior is kept even if the
client is hidden or minimized for some reason.
- If all client tags are unselected, avoid overlap with all other
floating clients which either are sticky or share at least one tag
with the placed client, and use the layout of the first tag of the
placed client to determine the floating status.

A call to cairo_close_path() adds a straight line to the beginning of
the current sub-path. This is used in some of the shapes to, well, close
the shapes.
Sub-paths can be created explicitly via cairo_new_sub_path(), but also
implicitly via cairo_move_to(). When a new sub-path is started, there is
no current point on the path. This means that e.g. cairo_line_to() is in
this start equivalent to cairo_move_to() (= no line is created) and that
cairo_curve_to() first does a cairo_move_to() to the beginning of the
curve. Similarly, cairo_arc() and cairo_arc_negative() first do a
line_to() to the beginning of the arc, and this line_to() can be
implicitly turned into a curve_to().
The problem with the code in gears.shape is that parts of the code
(implicitly) assume that there is not yet any path when the shape
function is called. If this assumption is broken, the call to
close_path() could go to the wrong point, because the path did not start
at the expected position.
Most of the functions in gears.shape already implicitly start a new
sub-path via a call to cairo_move_to(). Those that do not (necessarily)
begin with a call to cairo_move_to() are handled in this commit: They
get an explicit call to cairo_new_sub_path().
This change fixes the issue reported at
https://github.com/awesomeWM/awesome/pull/2804, because the shapes will
no longer be influenced by the pre-existing path. The move_to() that was
left around and caused that issue turns into a degenerate part (it only
has a move_to(), so nothing can be drawn) and is then discarded by
cairo.

Cairo's save/restore methods handle all properties except for the
current path. The path is just left as-is.
A widget's draw method could create some path without consuming it. This
path would then interfere with random things later which did not expect
a path to already exist.
This commits adds calls to cairo_new_path() in the relevant positions to
clean things up.
This not only applies to a widget's draw method, but also
{before,after}_draw_{child,children}. However, these methods could (for
whatever reason) create paths that are to be consumed in one of the
other methods. To keep this working, the path is only cleared after all
of these methods ran.
I do not expect this commit to break anything, because a widget cannot
really assume much about what widget is drawn after it. Especially so,
because partial redraws could mean that some later widget is skipped and
not redrawn.
This should fix the issue reported at
https://github.com/awesomeWM/awesome/pull/2804.

This function checks if a given cairo context has an empty clip. It was
written with the assumption that cairo_clip_extents() produces the x, y,
width, height of the clip extents. However, that function actually
produces x1, y1, x2, y2, where (x1, y1) and (x2, y2) are the corners of
the rectangles.
Due to the way the function is written, it will return non-zero numbers
when there is a translation (cr:translate()). Thus, this function worked
basically never.
Fix this by checking if both points have the same X- or Y-coordinate.

With draw_empty=false, :fit() can return 0,0. Then, when :layout() is
called, it will compute negative widths and heights. This can then cause
lots of problems later on.
Avoid this by having :layout() return nothing instead of producing
negative sizes.

Also document the `test` property as deprecated. It exists because the
older API (`naughty.notify`) had it. It exists on purpose in the
rewrite, it cannot just be removed even if it was never in a release.
This will be shared by the notifications stored in a wibox/wibar and the
ones using a popup. It extends the constraint and margins container
to take care of some boilerplate code. While other widgets have their
own public API, those 2 are private since they are not different enough
to warrent a new public module.
There is some boilerplate code that make using the widget_template
harder when using the raw `wibox.container.background`. This widget
takes care of it.
It is a normal textbox with some extra boilerplate code. Having this
in a separate widget allows the notification to be defined from rc.lua
without a ton of beautiful options and connect_signal.
This way their name doesn't get mangle by the broken magic. It will also
eventually allow to `error()` in the template when the implicit
`@function` is used.
This commit also fixes a large number of issues found while
proof-reading everything.
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.
