Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
This patch introduces two new buttons to apply the current theme being
edited to the whole system and to reset to the previously selected
on disk system theme.
This means all three window titles are visible, regardless of what the
TitleHeight and BorderThickness values are. :^)
The one exception is when TitleHeight is less than the height of the
title text. WindowManager ensures that the real title height is at
least enough to fit the text, so if the value is set to less than that,
the window titles will start to overlap. So, don't set values that are
impossibly small!
This is quite a radical change. The previous UI was very easy to add new
properties to (just add to the FooRole enum and it automatically
works), but not so nice to use: A ComboBox for selecting a property,
and then a box to edit that property's value. This makes it difficult
to compare different properties or edit multiple together without a lot
of back-and-forth.
This new design gives each property its own editing widgets, with those
categorized into several tabs. To try and avoid increasing the
maintenance burden for this, the UI is generated from the
`windows_tab`, `widgets_tab` and `syntax_highlighting_tab` variables,
which are basically just lists of which properties go in that tab. One
of the `FooProperty.gml` files is loaded to create each property's
widgets.
We only need to fire these callbacks when we want to change the palette.
So, when setting widget values to match a palette that has just been
loaded, or to show the value of the role selected in a ComboBox, we can
skip the callbacks. This saves some work, and means we can reliably use
on_palette_change to know when the palette has actually been modified.
There are two different things in ThemeEditor that want to know when a
palette changes:
1. The PreviewWidget subclass, so it can update its preview.
2. The ThemeEditor itself, so we know that the palette is modified.
Using a protected virtual function for 1 means that we can do 2 without
them fighting over the same on_palette_change callback.
This is to simplify the code, as Color, Alignment, Flag, Metric and Path
RoleModel classes looked exactly the same.
Additionally, I've added a try_create() function for error propagation.
:^)
Currently this method always succeeds, but that won't be true once we
switch to the Core::Stream API. :^)
Some of these places would ideally show an error message to the user,
since failure to save a file is significant, but let's not get
distracted right now.
I've attempted to handle the errors gracefully where it was clear how to
do so, and simple, but a lot of this was just adding
`release_value_but_fixme_should_propagate_errors()` in places.
Now that the GML formatter is both perserving comments and also mostly
agrees to the existing GML style, it can be used to auto-format all the
GML files in the system. This commit does not only contain the scripts
for running the formatting on CI and the pre-commit hook, but also
initially formats all the existing GML files so that the hook is
successfull.
Implement a mechanism that allows us to alter colors so that they
mimic those a colorblind person would see. From the color we can then
alter the colors for the whole preview so we can simulate everything
in the theme including icons/decorations.
This filter is also available as a Filter in LibGfx so it can be
reused in multiple other places.
The color simulation algorithm is based on this one
https://github.com/MaPePeR/jsColorblindSimulator publicly available.
Previously, the active window being centered, and then the inactive one
being higher, meant having an awkward gap at the bottom. This is a
simple fix, and not perfect, but it helps. :^)
The GUI for this is a bit odd, especially since we only have one flag,
but otherwise adding new flags would require modifying ThemeEditor. At
least it is consistent with the other theme properties.
