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/.

|
||
## Quick lookup: I want to ...
|
||
|
||
* **Print text** → `<stdio.h>` (`printf` / `puts` — fast, no colour) or
|
||
`<conio.h>` (`cprintf` / `cputs` — applies `textcolor`).
|
||
* **Read a key** → `<conio.h>`: `getch()` (blocking, no echo), `getche()` (echo),
|
||
`kbhit()` (non-blocking poll).
|
||
* **Open / read / write files** → `<unistd.h>` + `<fcntl.h>` (POSIX) or
|
||
`<stdio.h>` (`fopen` family).
|
||
* **List a directory** → `<dir.h>`: `ffirst` / `fnext`.
|
||
* **Draw pixels** → `<gfx.h>`.
|
||
* **Allocate memory** → `<stdlib.h>`: `malloc` / `free` / `calloc` / `realloc`.
|
||
* **Get current time** → `<time.h>`: `getdatetime` or POSIX `time`/`localtime`.
|
||
* **Read mouse** → `<mouse.h>`.
|
||
* **Read an env var** → `<sprinter.h>`: `getenv` / `putenv`.
|
||
* **Set text colour** → `<conio.h>`: `textcolor(COLOR_YELLOW)`,
|
||
`textbackground(COLOR_BLUE)`, or `textattr(COLOR(fg, bg))`.
