0.11.1

This release adds a new shape-run-cache feature that, when enabled, will cache the results of shaping operations to significantly improve performance, at the cost of increased memory usage. Make sure to trim the cache with the ShapeRunCache::trim function regularly. Also make sure to set keep_ages to a large enough value that entries are not removed too early, as minor changes in the source text can switch between active entries (such as adding or removing a space in the middle of a word).

This release contains a large refactor (#206), performance improvements, and bug fixes.

Links

• Crate on crates.io
• Documentation on docs.rs

Added

• Add function to set metrics and size simultaneously
• Cache rustybuzz shape plans
• Add capability to synthesize italic
• New wrapping option WordOrGlyph to allow word to glyph fallback

Fixed

• Buffer::set_rich_text: Only add attrs if they do not match the defaults
• Do not use Emoji fonts as monospace fallback
• Refresh the attrs more often in basic shaping
• Buffer: fix max scroll going one line beyond end
• Improve reliability of layout_cursor
• Handle multiple BiDi paragraphs in ShapeLine gracefully
• Improved monospace font fallback
• Only commit a previous word range if we had an existing visual line

Changed

• Significant improvements for Editor, SyntaxEditor, and ViEditor
• Require default Attrs to be specified in Buffer::set_rich_text
• Bump fontdb to 0.16
• Allow Clone of layout structs
• Move cursor motions to new Motion enum, move handling to Buffer
• Ensure that all shaping and layout uses scratch buffer
• BufferLine: user layout_in_buffer to implement layout
• BufferLine: remove wrap from struct, as wrap is passed to layout
• Refactor of scroll and shaping
• Move color and x_opt out of Cursor
• Add size limit to font_matches_cache and clear it when it is reached
• Update swash to 0.1.12
• Set default buffer wrap to WordOrGlyph

Removed
