This template allows to display a sequence of events for the clients,
tags and screens. Currently, it is hard to display images where the
state of an object is more complex than "here how it was before" and
"here how it is now". With this template, it is possible to have a
timeline of events from the initial states to the final states.
Now, as the line count shows, this isn't small. It is in fact an
enormous template. Worst still, this commit is the first *half* of
it. The second half adds the ability to `print()`, display
inline code and support mouse and keyboard events. The code also isn't
world class. Maintaining this template might be non-trivial in the
long run. I am fully aware of those issues. On the other hand, there
is ~100 places where this will be used once the entire
"new rule library" project is completed. This will bring the ~1.2k
line of code to ~12 lines per consumer. From that point of view,
it makes a lot more sense to merge this given how useful it is
at explaining changes within the "core objects".
It is also important to keep in mind that there is currently very
little or no documentation (beside the mandatory one-liner summary)
for these concepts. Those are the most important aspects of AwesomeWM
API and they are the least documented. This is just wrong.
There are some usecases when terminal font not providing those characters at all or they're provided by fallback font with different dimensions.
Both of the issues above could affect readability/clarity of the version output.
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.
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 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)
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.
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 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.
Now that the previous commits add a proper fallback and a way to test
this, enable the second half.
As long as the default screen mode (`--screen auto`) *or* the `rc.lua`
doesn't execute too much code in the global context, this wont break
much.
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.
Previously, it would create screens outside of a visible output area. In
the following commit, this will be tracked and a warning is printed when
it happens. This makes the test fail.
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.
