nightshade-text

Text shaping, styling, and glyph geometry, built on cosmic-text.

It shapes a string into laid-out glyphs, describes how a run should look, and holds the slot storage consumers index into. Turning glyph geometry into GPU buffers is left to the caller.

This is a leaf crate: it depends on no other nightshade crate, so the renderer and the retained UI can both build on it. Anything else can too, not only the nightshade engine.

[dependencies]

nightshade-text = "0.57.0"

What lives here

• text_data: TextMesh and TextVertex, the geometry shaping produces, plus the FontKind and alignment enums that describe a run. Always available.
• font_engine: FontEngine, owning the font database, the shaping context, and the glyph rasterization cache. Four fonts are embedded: Roboto, JetBrains Mono, Material Icons, and Lucide.
• text: TextProperties for styling, TextCache for slot storage, and TextState pairing a cache with a font engine.
• text_wrapping: wrap_text, re-flowing a string to a width.

Everything here sits on the path from a &str to laid-out glyphs. Nothing that is not on that path belongs here.

Features

default = ["shaping"]

With shaping off, the crate is the geometry and styling types alone, with no font database and no shaping dependency.

Examples

cargo run --example shape   # shape and measure a string, then re-flow it to a width
