- 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
* Set an index for the last saved change
I added an index that represents the last saved change.
Editors are considered to be unsaved or modified if the current change
is different from the save index. In other words, if the last saved
change is `5`, undoing or redoing past that change should indicate that
the editor has been modified.
This is needed to fix two bugs in COSMIC Edit:
* https://github.com/pop-os/cosmic-edit/issues/116
* https://github.com/pop-os/cosmic-edit/issues/128
* Unit test that confirms pivot logic works
I'll most likely simplify the API as end users don't have a way to
cleanly use `Pivot::Exact` without access to the internal command
buffer.
* Simplify save point API
* Implement more save point unit tests
A unit test for an edge case currently fails but normal usage works.
* Fix edge case for empty command index and pivot
* More save point unit tests for common use cases
- Scroll is identified by line index and layout index, instead of just
layout index
- Shaping has the option to prune, where caches outside of the scroll
view are cleared
- Syntax editor no longer requires layout of all lines, only of lines
inside scroll
- BufferLine has a metadata field that can be used by other abstractions
to know when text was changed
