* feat: add Ellipsize enum
* chore: API changes needed for ellipsize
Decided not to change "layout()" function for now to avoid breaking the
interface. For now.
* chore: shape ellipsis
* feat: Ellipsize::Start
Since it can only have 1 line, it's easier to implement.
* DROPME: temporarily change rich-text for testing
* test(ellipsize): Testing Ellipsize::Start
Long text in small buffer should produce ellipsis glyphs
* fix: do not need font_system anymore
We moved ellipsis shaping elsewhere so no need to pass font_system to
layout function (which also was recreating a new one in the tests every
time making them take forever).
* feat: Ellipsize::End
* improv(ellipsize): use a single ellipsis shape
* improv: Ellipsie::End && Wrap::None
There is no need to layout the whole line if it's not going to fit.
* fix: mixed bidi text when Ellipsize::End && Wrap::None
* chore: clean up and simplify when line.RTL==span.RTL
* fix(ellipsize): last word is not (word_count -1) if iter().rev()
* refactor(layout): extract the layout algorithm to make it more readable
* improv(ellipsize): Ellipsize::Start && Wrap::None
we iterate in reverse and only layout what's going to be visible
* Revert: delete the previous approach of post processing ellipsis
* doc: explain the interaction between Ellipsize and Wrap
* chore: lower the scope
* feat: Ellipsize the last line of a paragraph
For now only the number of lines is supported
* fix: clear ellipsized field on visual lines
This was causing ellipsis to show on random lines
* chore: remove old tests
will add better tests soon
* chore: clean up changes from previous attempt
* fix: consider the ellipsis width when doing alignment
* feat(ellipsize): add `Height` limit to `Ellipsize`
* fix: ellipsize the start of the last line correctly
* fix: ellipsize at the start of mixed bidi lines
* feat: Ellipsize::Middle
* fix: consider ellipsize::middle when calculating alignment correction
* refactor: improve readability
* refactor: deduplicate "fit_glyphs"
* refactor: combine backward and forward layout into one (wip)
* fix: Backward works in the unified layout_spans
* chore: clean up
* fix: Ellipsize::Middle
* fix: handle large words in bidi boundaries
* chore: clean up and some refactoring
* fix: ellipsis is now the same level as the surrounding text
* fix: try to fit more when ellipsizing::middle
* improv: ellipsis now have the same level as the neighbors
This makes ellipsized RTL text inside a LTR line more readable.
before:
Hello سلام...خوبی؟
Hello خولی؟...سلام
* fix: some extra words were being rendered in Ellipsize::Middle
This was causing the last word (if it's not the same level as the rest)
to be rendered outside the buffer.
* test: a few test cases for ellipsize
* fix: assign the correct byte range to ellipsis
this should fix the panic when selecting or clicking on or near the
ellipsis in the editor.
- 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
* 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
For use cases that want to reverse the alignment of RTL
lines, this avoids needing to check the RTL status of every line
manually.
This is a breaking change.
