kb_text_shape (v2.10, JimmyLefevre) had been LOST from the sx tree — ffi/stb_truetype.sx referenced repo paths that no longer existed (and nothing runs glyph_cache, so the dangling unit never fired). The trimmed copy returns from the m3te project as a proper vendor: curated c/kbts_api.h decls over the full upstream header, README with provenance, and examples/1627 pinning context + font creation so the unit compiles and runs in-suite. file_utils (in-house asset-read helper with the Android AAssetManager hook) gets the same unit shape. modules/ffi/stb_truetype.sx is gone: glyph_cache imports the three vendored units (stb_truetype, kb_text_shape, file_utils) directly.

# vendors/kb_text_shape — OpenType text shaping for sx programs
|
|
|
|
- Version: **v2.10** (version history at the top of the header)
|
|
- Source: <https://github.com/JimmyLefevre/kb> (`kb_text_shape.h`)
|
|
- License: zlib-style permissive (see the header's license block)
|
|
- Files: `c/kb/kb_text_shape.h` (the full upstream single-header,
|
|
~30k lines), `c/kb_text_shape_impl.c` (defines
|
|
`KB_TEXT_SHAPE_IMPLEMENTATION` and includes it), and
|
|
`c/kbts_api.h` — a hand-curated MINIMAL declaration header carrying
|
|
only the bound surface, so decl synthesis never parses the full
|
|
upstream header.
|
|
|
|
`#import "vendors/kb_text_shape/kb_text_shape.sx"` resolves through
|
|
the stdlib search paths; the implementation compiles once per machine
|
|
through sx's object cache. Shape contexts, fonts, runs, and glyphs are
|
|
opaque pointers on the sx side (modules/ui/glyph_cache.sx is the
|
|
reference consumer; `examples/1627-vendor-kbts-shape-context.sx` pins
|
|
context + font creation in the sx suite).
|
|
|
|
To upgrade: replace `c/kb/kb_text_shape.h` with a newer upstream copy,
|
|
extend `c/kbts_api.h` if the bound surface grows, update this file,
|
|
and rebuild (the object cache keys on source bytes).
