This breaks GSortingProxyModel selection preservation across resorts.
I'm not yet sure how we're going to solve that, but it's going to have
to work a bit differently than before, since the model itself no longer
knows what's selected.
Selection is now managed by GModelSelection which allows us to select
any arbitrary number of items, and to have different selections in
different views onto the same model. Pretty sweet. :^)
Each GAbstractView now has a GModelSelection backed by a simple
HashTable<GModelIndex>. When the selection changes somehow, the view
gets notified via the notify_selection_changed() callback.
In the future it will probably make sense to move to using some kind of
ranges as the internal representation instead.
`GTabWidget` now allows the user/caller to get the currently active
tab widget, meaning that actions that are applied globally (such as
an 'Apply' or 'OK' button) can now react to specific tabs etc.
An interactive application to modify the current display settings, such as
the current wallpaper as well as the screen resolution. Currently we're
adding the resolutions ourselves, because there's currently no way to
detect was resolutions the current display adapter supports (or at least
I can't see one... Maybe VBE does and I'm stupid). It even comes with
a very nice template'd `ItemList` that can support a vector of any type,
which makes life much simpler.
Now that the kernel supports thread-local storage, we can declare errno
with the __thread keyword, which causes it to be per-thread.
This should fix all the stupid issues that happen when many threads use
the same errno. :^)
We were already borrowing a getopt() from the BSD family until the day
we write our own. This patch borrows a slightly more modern one so we
also get getopt_long().
Fixes#190.
See also #91 for the desire to eventually NIH our own getopt()..
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)
This is not as perfect as it is elsewhere in the system, as we cannot
really change how terminal "thinks about" characters and bytes. What
we can do though, and what this commit does, is to *render* emojis, but
make it seem as if they take up all the space, and all the columns their
bytes would take if they were all regular characters.
From here on, all strings displayed to the user are expected to
be encoded as UTF-8. The next few commits will deal with a few
existing places where this requirement is currently violated.

This class can locate and load emojis, which are expected to be stored
as regular PNG images at /res/emoji/U+XXXX.png, where XXXX is the
character codepoint.

This is a variant of the enqueue() API that returns immediately and
may fail. It's useful when you don't want to block until the audio
server can receive your sample buffer.
This solves an issue in GScrollableWidget where hiding one of the two
scrollbars needs to trigger a relayout since the other one should grow
into the "shared space" in the bottom right corner.
A GWidget can now override custom_layout() which will be called at any
time we would normally delegate work to the GLayout, e.g on resize
or child visibility changes, size policy changes, etc.
There were various little mistakes in the width calculations used by
the line-wrapping layout code.
With this patch, we should no longer see the horizontal scrollbar get
enabled with line-wrapping enabled. I will hide the scrollbar in a
separate patch.
text_position_at() was returning -1 if the position wasn't in
the bounds of a visual line. Now if the position is past the last
line, we simply return the last line index instead of -1.
Fixes#502.
