Module shaper 

Shaper: a text engine of our own, so a host without one can still be told where every glyph lands.

Structs

Placing 🔒

The pen walking a shaped run, and the cluster it is in the middle of.

Shaped 🔒

One glyph as the shaper reports it, in font units.

Shaper

One typeface, shaped by harfrust and broken into rows by the desktop engine’s rules — the whole of what TextLayout asks of a host, with no toolkit under it.

Constants

UNKNOWN 🔒

The character a shaper reports for a byte it cannot read back.

Functions

place 🔒

The shaped run placed along one endless row, one glyph per character: a cluster the shaper folded into fewer glyphs than it has characters is padded out with zero-advance continuations, so cursor arithmetic above this can count characters.
