And call `extern crate std` when the feature is enabled.
I've read this is the good practice on how to do it.
So that the std prelude is no longer included automatically.
There is then less difference between std and and no-std build which
should avoid surprises in the CI when we use things from the prelude.
The downside is that there is a bit of churn in the tests
The struct held provides access to the design metrics of the font scaled
to the font pixel size used by the element.
ChangeLog: Slint Language: Added font-metrics property to `Text` and `TextInput`.
Closes#6047
This adds a new wrapping mode called `char-wrap`, which allows for wrapping at any character.
Currently, it only supports the Qt backend, with the other backends falling back to `word-wrap` when this option is selected.
Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
Only the hand-picked sensible things, not all of it ;-)
Also fix a few typos that cspell complained about when I
tried to commit and some formatting changes that cargo fmt
insisted on when commiting.
Remove platform glyph abstraction, just use non-zero u16 as glyph index
like everyone else. As a bonus, this reduces the memory consumption of
the glyph buffers per glyph from a size of a pointer to the size of the
u16.
The AboutSlint text has a forced linebreak in it, which becomes a box
glyph on MCUs when the font on the host system doesn't use an empty
glyph but a box glyph for \n.
This patch explicitly excludes glyph clusters from text fragments that
feed into lines that originate from one of the three valid separators:
ascii newline, unicode paragraph and unicode line separators.
Separate the text shaping functionality from font metrics by having a
FontMetrics trait next to the TextShaper. AbstractFont is the combining
super trait. This allows eliminating the font height member from
TextParagraphLayout and improving the overall naming of fields and
types.
Finally, this prepares the API for composability of TextShaper for font
fallback handling.
Use the term glyph cluster instead of grapheme where we're dealing with
the glyphs for line breaking. Those may coincide with grapheme
boundaries, but aren't required to.
Replace the abstract glyph trait with a glyph struct. That way the text
layout code can operate properly on a struct with fields, instead of on
functions on a trait (some of which returning a mutable reference). The
input is a glyph with offset, advance, etc. - everything needed for the
layout and the output is a position along with the platform specific
glyph data.
Remove the font reference field anymore as it's not needed anymore and
remove the manual clone implementations. Those were needed because
otherwise the TextShaper trait would have to also support clone - as
[derive(Clone)] imposes that. Now we can impose that just on Glyph and
that's easy and makes sense.
Replace the lazy text shaping with an up-front shaping of all text. It
needs to be done eventually anyway, so by doing it in one go we can
avoid interior mutability and simplify the code overall.
Make ShapeBoundaries produce single offsets, there's no need for
ranges as the boundaries are contiguous.
In GraphemeCursor collect all boundaries in one go as text runs, to
simplify state handling. This will be needed anyway for recording bidi
runs in the future.
The unicode linebreak iterator always produces a mandatory break at end
of text. This is not only confusing, but also inconsistent with the
simple line break iterator and with trailing spaces it could cause the
line break algorithm to emit empty lines at the end of text.
