This will be useful to address the screens by roles/names in the client
and tag rules. Since the sceen rules will make setups where sceens are
attached and removed much easier to work with, using indexes or output
names in the rules becomes a limitation.
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 commit, the C code stores if the screen was created with
`fake_screen` and also stores if the Lua side "promise" to manage
(aka, track the viewport and remove it) the object. There is now
3 kind of screens:
* Managed by C (created and deleted by the core code)
* Managed by Lua (replicate the core code, but with more hooks)
* Unmanaged (created directly with fake_screen)
It moves the actual place where when screen array is stored into the
area object. This allows to store the outputs when screens are not
automatically created.
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 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.
Fixes#2640
Ref #1373
Between xcb_grab_server() and xcb_ungrab_server(), XCB's output buffer
might fill up. Thus, the GrabServer request might already have been sent
to the server, but the following UngrabServer request could end up in
XCB's output buffer. There, it might sit around for quite a while and
cause problems.
Since we cannot detect when XCB's output buffer fills up, we just always
flush after generating an UngrabServer request.

Instead of refreshing screens at the end of the current main loop
iteration, this now uses a GLib idle source with a very low priority.
This increases the chance of batching multiple refreshes together. Also,
this means that awesome_refresh() does less work.

As requested in the review, instead of just having a single string
argument, selection_acquire() now has a table as its argument. It
searches the string under the "selection" key here.

Today I learnt that _NET_WM_STATE_STICKY means something else than I
previously thought.
ICCCM and EWMH support virtual desktops that are larger than the actual
screen. The idea is that one can scroll through this virtual desktop,
which means that e.g. all windows move to the left, so one can see the
windows that are further to the right.
_NET_WM_STATE_STICKY indicates that a window is sticky. This means that
it does not scroll with the virtual desktop, but instead sticks to its
current position.
In AwesomeWM, we use a different definition. A sticky window is always
visible, even when it is not tagged with any of the currently selected
tags. This behaviour is indicated in EWMH with a special value of
_NET_WM_DESKTOP. This commit updates the code to actually set this
special value.
This fixes attaching tabs in Google Chrome when the "target window" is
sticky (in the AwesomeWM sense).

When a selection transfer is done, we are no longer interested in events
from the selection window. However, this happens after we set the
property to indicate end of transfer, not before.
The (untested) theory here is that this should make selection transfers
from AwesomeWM to AwesomeWM, i.e. internal transfers, work.

This commit adds a "continue" signal on transfer objects. This signal is
used to request the next chunk of data from Lua after the last one was
sent.

Large amounts of data have to be send in chunks via the INCR protocol.
This commit adds support for that protocol to selection transfers.

This commit makes :send{ data={"TARGETS", "UTF8_STRING"}, format="atom"}
work correctly. This was tested with xclip -o -target TARGETS.
With this commit, it becomes possible to implement the TARGETS target.

This now creates a selection transfer object and requests Lua to reply
to the request via this object. However, so far no answer is possible.

This allows to voluntarily give up ownership of a selection. Because
selection acquire objects cannot be garbage-collected before they are
released, this also gets rid of the function destroying the window when
its selection acquire object is destroyed. Instead, the window is
immediately destroyed when no longer needed.

The list of supported formats of the selection is queried by requesting
the target TARGETS. This target is a list of ATOMs and needs special
handling which is what this commit adds.

This commit adds support for simple selection transfers. INCR support is
still missing. The API is that a selection getter object emit the "data"
signal when some data becomes available and "data_end" when all data was
received.

So far they do not do match. The selection and target are specified and
a window is created for a transfer, but no transfer is actually started
yet.
