First substantive commit: the entire Sprinter C compiler tree on top of
the bare README+gitignore initial commit.
What's in here:
bin/sprinter-cc — driver script invoking SDCC + linker + mkexe
libc/ — Sprinter-specific libc layer over ESTEX/BIOS
(conio, gfx, io, mem, stdio + headers)
runtime/ — crt0 variants (default/small/banked/minimal)
+ heap + bank trampolines
toolchain/ — mkexe (SprintEXE packer, C + tests)
examples/ — 30 demo programs (gfx, file I/O, env, time, …)
lib/Makefile — builds the libc archive (sprinter.lib)
docs/ — converted Sprinter manuals + asm reference samples
third_party/ — solid-c reference compiler dump + sdcc setup script
release_docs/ — packaging / release notes
gitignore overhaul:
• Drop dangerous blanket patterns: *.asm (would hide docs/samples/*.asm)
and *.exe (case-insensitive match was hiding third_party/solid-c/*.EXE
on macOS APFS). Replaced with examples/*/*.{asm,exe,…} and lib/*.lib.
• Restore tracking of toolchain/mkexe/tests/{one,big}.bin — those are
INPUT fixtures, not build outputs.
• Collapse the duplicated SDCC/C/Sdcc sections into one section per
concern (build outputs / vendored / OS-junk).
• Add .sprinter-cc-*/, build/ (catches lib/build/ too), .claude/.

* dir.h — directory iteration via ESTEX F_FIRST / F_NEXT ($19 / $1A).
|
|
*
|
|
* ffirst(pattern, &buf, attrib)
|
|
* Initialises the search. The pattern is a DOS wildcard like
|
|
* `*.TXT` or `DATA\\*`. attrib is the search mask (use FA_NORMAL
|
|
* to match plain files, OR in FA_DIREC to include subdirectories).
|
|
* Returns 0 on success (buf is populated), -1 on failure (errno set).
|
|
*
|
|
* fnext(&buf)
|
|
* Steps to the next matching entry, reusing the same buf. Returns
|
|
* 0 on success, -1 when no more files match (errno = ENOENT) or on
|
|
* other errors.
|
|
*
|
|
* The buffer fields below mirror ESTEX's layout exactly so we can hand
|
|
* it straight to the kernel. Use `buf.found_name` (NUL-terminated DOS
|
|
* "name.ext" form) to display results.
