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(definesKB_TEXT_SHAPE_IMPLEMENTATIONand includes it), andc/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).
