* Use HarfRust for shaping
* Replace ttf-parser with skrifa entirely
* Fix clippy lints
* Add shape plan cache
* Bump harfrust and skrifa

* Cache font ID with plan
* Tune shape plan cache for "BiDi Processing" bench
Refactors the Editor's scrolling implementation to be pixel-based instead of line-based. This provides smoother and more granular scrolling, which works more consistently across different input devices (like trackpads).
- The `Action::Scroll` variant now takes `pixels: f32`.
- The `Editor` now processes scroll actions using pixel values directly.
- Examples have been updated to reflect the new scrolling behavior.
- Fix string formatting with modern interpolation syntax
- Improve Debug implementation with finish_non_exhaustive()
- Fix function placement in shape.rs to avoid items_after_statements warning
- Use more idiomatic Rust patterns (map_or_else, next_back)
- Clean up conditional imports in vi.rs
- Convert multiple methods to `const` functions for optimization and consistency
- Introduce `core_maths` for enhanced no-std compatibility
- Update `Cargo.toml` for the new optional dependency and feature adjustments
* Optimize BidiParagraphs with ASCII fast path - Added fast path for ASCII text that avoids BidiInfo allocation - Added some text shaping benchmarks
* refactor: fix clippy warnings and cleanup imports
- Skip expensive grapheme iteration for simple ASCII words
- 32% performance improvement for code-like text
- 5-7% improvement for general ASCII content
- No regressions for Unicode text processing
- Conservative ASCII detection maintains correctness
* Update editor.rs
* Makes sure indent_required is calculated according to the selection type
removed the redundant check for required_indent == 0,
introduced a slightly different path for when no selection = None, and calculated the required tab width and indent position accordingly.
* Undo typo
undid an accidental move of a redraw call outside of a loop
* Corrected indenting with rustfmt
formatted the code with rustfmt to pass the failing CI checks
* Variable font support
Here's a pretty naïve solution for variable fonts.
The iterator doesn't use the match keys' weight, but instead tries to
get the requested ideal weight, if the font is variable, otherwise it is
ignored and the actual (non-variable) weight is used. This is because I
didn't implement finding variable weight support for match keys; doing
so would be impossible without parsing TTF files when matching and I
didn't want to add that potentially expensive infrastructure if not
entirely necessary.
This is a breaking change, and I'm open for ideas on how to fix that
if it's an issue.
* cargo fmt
* Add variable font example to rich-text example
Font family know gets used when querying the font.
Not sure if this solution is good, if the old code is even needed.
This works for me, which makes it good enough for me.
Due to https://github.com/pop-os/cosmic-text/pull/141 the LayoutRunIter incorrect checks to see if the baseline is past the visible bounds of the buffer, instead of using the maximum ascent and maximum descent from the baseline.
