The stb headers move from the repo-root vendors/ (resolvable only with CWD = sx repo) into library/vendors/ following the sqlite convention — bindings module + c/ sources + provenance README — so '#import "vendors/stb_image/stb_image.sx"' (image v2.30 + image_write v1.16) and '#import "vendors/stb_truetype/stb_truetype.sx"' (v1.26) work from any consumer via the stdlib search paths. modules/ffi/stb.sx dissolves into the stb_image vendor; modules/ffi/stb_truetype.sx keeps its non-stb text-shaping companions and re-imports the vendored unit. examples/1625 pins a deterministic in-memory BMP decode; examples/1626 pins font init + metric invariants against the system Helvetica.
vendors/stb_image — image decode/encode for sx programs
- stb_image: v2.30; stb_image_write: v1.16 (version comments at the top of each header)
- Source: https://github.com/nothings/stb (
stb_image.h,stb_image_write.h) - License: public domain / MIT, dual (see the headers' license blocks)
- Files:
c/stb_image.h+c/stb_image_impl.c,c/stb_image_write.hc/stb_image_write_impl.c(each impl .c defines the*_IMPLEMENTATIONmacro and includes its header)
#import "vendors/stb_image/stb_image.sx" resolves through the stdlib
search paths; the decls (stbi_load, stbi_load_from_memory,
stbi_image_free, stbi_write_png, …) are synthesized from the
headers, and the implementation compiles once per machine through sx's
object cache. examples/1625-vendor-stb-image-decode.sx pins an
in-memory BMP decode in the sx suite.
To upgrade: replace the headers under c/ with newer upstream copies,
update this file, and rebuild (the object cache keys on source bytes).
