Crate smudge_text 

Text layout for Smudge, backed by parley.

This crate owns parley’s font and layout contexts in a per-thread TextSystem, lays out text through TextLayout, and shares a TextStyle with widgets through reactive context.

The fonts in this crate’s assets/fonts directory are embedded by default, so layout is deterministic and never depends on the fonts installed on the host. System font discovery is opt-in through the system-fonts feature and is unavailable on wasm.

Without the complex-scripts feature, line and word breaks follow the Unicode rules alone. Chinese and Japanese still wrap between characters, but word selection treats each Han character as a word, and Thai, Lao, Khmer and Burmese, which put no spaces between words, wrap only at spaces. The feature compiles in the break dictionaries for those scripts, at about 3 MB per binary and about 5 percent more layout time for other text.

use smudge_text::{TextLayout, TextSystem, TextStyle};

TextSystem::bundled_only().install();

let style = TextStyle::default();
let layout = TextLayout::new("Hello, Smudge", &style, None);
assert!(layout.size().width > 0.0);
