v0.6.0

Name	Crates.io	Docs
Parley	Crates.io	Docs
Fontique	Crates.io	Docs

This release has an MSRV of 1.82.

Highlights

Parley now uses HarfRust rather than Swash. This means that Parley now has production-quality shaping for all scripts and can be recommended for general usage.

Migration

As Parley now uses it's own parley::BoundingBox in place of kurbo::Rect, you may need to convert the type if you were previously passing one of these values into a function that expects kurbo::Rect. The following function may be used to perform this conversion:

fn bounding_box_to_rect(bb: parley::BoundingBox) -> kurbo::Rect {
    kurbo::Rect::new(bb.x0, bb.y0, bb.x1, bb.y1)
}

Added

Parley

• Shift-click support through Selection::shift_click_extension and PlainEditorDriver::shift_click_extension. (#385 by @kekelp)
• Add some benchmarks using Tango. (#405 by @taj-p)

Fontique

• Cache character mapping metadata for each font to improve performance of font selection. (#413 by @dfrg)
• Upgrade icu4x dependencies to v2.x. (#418 by @nicoburns)
• Added an unregister_font method to remove a font from a collection. (#395 by @taj-p)

Changed

Parley

• Breaking change: Alignment variants have been renamed to better match CSS. Alignment::Justified is now Alignment::Justify and Alignment::Middle is now Alignment::Center. (#389 by @waywardmonkeys)
• In the PlainEditor, triple-click now selects paragraphs rather than words (#381 by @DJMcNab)
• Updated to accesskit 0.21. (#390 by @mwcampbell)
• Uses HarfRust for text shaping. (#400 by @taj-p)
• Parley no longer depends on peniko or kurbo. (#414 by @nicoburns):
  • Breaking change: The use of peniko::Font has been replaced with linebender_resource_handle::FontData, as such parley::Font is now called Parley::FontData.
    Note that this is the same type as in previous releases, and so is fully backwards-compatible, just with a different name.
  • Breaking change: The use of kurbo::Rect has been replaced with a new parley::BoundingBox type.

Fontique

• The fontconfig backend, used to enumerate system fonts on Linux, has been rewritten to call into the system's fontconfig library instead of parsing fontconfig's configuration files itself. This should significantly improve the behavior of system fonts and generic families on Linux. (#378 by @valadaptive)
• Fontique no longer depends on peniko. The use of peniko::Blob has been replaced with linebender_resource_handle::Blob. This is unlikely to affect users of the crate. (#414 by @nicoburns)

Fixed

Parley

• Selection extension moves the focus to the side being extended. (#385 by @kekelp)
• Ranged builder default style not respecting scale. (#368 by @xStrom)
• Cluster source character not correct. (#402 by @taj-p)
• Don't justify the last line of a paragraph. (#410 by @taj-p)

Fontique

• Font family name aliases (secondary names for font families, often in another language) not being registered. (#380 by @valadaptive)

New Contributors

• @kekelp made their first contribution in #385
• @taj-p made their first contribution in #395

v0.5.0

Name	Crates.io	Docs
parley	Crates.io	Docs
fontique	Crates.io	Docs

This release has an MSRV of 1.82.

Added

Parley

• Editor features required by Android IME. (#334 by @mwcampbell)

Changed

Parley

• Breaking change: Layout::min_content_width, Layout::max_content_width, and Layout::content_widths have been replaced with Layout::calculate_content_widths, which does not internally cache the widths. This means that Layout is now Sync again, but callers will have to cache the min and max content widths themselves. (#353 by @valadaptive)
• Breaking change: the line height style property (StyleProperty::LineHeight and the line_height field on TextStyle) is now a LineHeight enum that allows you to specify absolute, font-size-relative, and font-metrics-relative line heights.
  Previously, it was always font-size-relative. (#362 by @valadaptive)
  • The default line height was previously LineHeight::FontSizeRelative(1.0) if you used RangedStyleBuilder, or LineHeight::FontSizeRelative(1.2) if you used TreeStyleBuilder.
    It is now LineHeight::MetricsRelative(1.0) in both cases.
    This will affect layout if you don't specify your own line height.
• Breaking change: {RangedBuilder, TreeBuilder}::{build_into, build} methods now consume self. (#369 by @dhardy)

New Contributors

• @dhardy made their first contribution in #361

parley	Crates.io	Docs
fontique	Crates.io	Docs

This release has an MSRV of 1.82.

Migration

Quantization of vertical layout metrics is now optional.
For an easy upgrade we recommend enabling it by setting quantize to true when calling LayoutContext::ranged_builder or LayoutContext::tree_builder.

Added

Parley

• Option to skip quantization of vertical layout metrics for advanced rendering use cases. (#297 by @valadaptive, #344 by @xStrom)
• The WordBreak and OverflowWrap style properties for controlling line wrapping. (#315 by @valadaptive)
• PlainEditor methods raw_selection and raw_text. (#316, #317 by @mwcampbell)
• PlainEditor::selection_geometry_with, the equivalent of Selection::geometry_with method. (#318 by @valadaptive)
• BreakLines::is_done method to check if all the text has been placed into lines. (#319 by @valadaptive)

Changed

Parley

• Breaking change: Selection::geometry, Selection::geometry_with, and PlainEditor::selection_geometry now include the line indices that the selection rectangles belong to. (#318 by @valadaptive)
• Updated to accesskit 0.19. (#294 by @waywardmonkeys, #348 by @xStrom)
• Now displaying selected newlines as whitespace in the selection highlight. (#296 by @valadaptive)
• Made BreakReason public. (#300 by @valadaptive)

Fontique

• Breaking change: Collection::register_fonts now takes a Blob<u8> instead of a Vec<u8>. (#306 by @valadaptive)
• Breaking change: Collection::register_fonts now takes an optional second parameter which allows overriding the metadata used for matching the font. (#312 by @valadaptive)

Fixed

Parley

• Text editing for layouts which contain inline boxes. (#299 by @valadaptive)
• Cursor navigation in RTL text sometimes getting stuck within a line. (#331 by @valadaptive)
• Using Layout::align on an aligned layout without breaking lines again. (#342 by @xStrom)
• Selection box height going below ascent + descent with small line heights. (#344 by @xStrom)
• Rounding error accumulation of vertical layout metrics. (#344 by @xStrom)

Fontique

• Panic on macOS when running in debug mode. (#335 by @NoahR02)

• @valadaptive made their first contribution in #300
