The added functions enable mixing colors and manipulating the opacity
of colors and brushes.
They enable the behavior of some of the available functions from SASS and are
added for future use for adding the Adwaita style (future PR).
In the compiler this is still very primitive, but an attempt to start a
generic interface. The basic assumption is that all item functions will
eventually need access to the window adapter and itemrc. Support for
additional arguments is still missing.
Also missing is support for the function access via rtti in the
interpreter, hence the hardcoding at the moment.
In the screenshot tests this works by setting SLINT_DEFAULT_FONT to
pointer to a directory, instead of a file. We then load all fonts in
that directory and consider their families the default unless a family
is specified. This way for "Noto Sans" a regular as well as an italic
version is registered in fontdb and returned in the list of font
fallback ids. embed_glyphs in the compiler then embeds those variants
and we find them at run-time.
Because we `return None` in case of error before we remove the file from `currently_loading`
we would then await forever next time we try to load that file.
This will cause a deadlock that can be causing #2709
For .slint files that are included, we canonicalize the path before
adding it into the import stack, to avoid duplicates. We didn't do that
for images in the global_embedded_resources.
Ensure this by canonicalizing as early as possible.
Fixes#2608
Commit 893983e8d3 "fixed" it to be 0 based as it was
documented. But that's a change of behavior so restore the previous behavior and
document it properly
* compiler: Make mapping from source offset to line/column more reusable
* compiler: Improve mapping of offset to line/column
* Fix unit tests after line mapping update
* interpreter: Add code to have a element picker mode
* slintpad: Add picker mode to the preview
* slintpad: Do not try to highlight "empty" highlight requests
* Slintpad: Cycle through all the possible elements in design mode
* Slintpad: Ignore builtins and eat less clicks
* Slintpad: Highlight the element selected in design mode
* Slintpad: Do not use static mut variable in design mode
* slintpad: Rename `set_current_element_information_callback`
* Interpreter: Do not use unsafe in design mode code
Done with: @ogoffart and @tronical
The old parser always try first to find `Foo :=` from the old syntax so it
would error saying it expect an identifier or `:=`
But if we don't find a component, don't try to parse it as a component too early
This way we get better error and better auto-completions
That way the error for an expression is at a better location, and
this also prevent the formater that removes space in expressions to
remove the spaces before the expression that shouldn't be removed
