Punch list §25 item 4.3.7e complete. New src/word_source/ttf_words.c registers TTF-TEXT ( c-addr u x y size color -- ): lazily loads the v1 default font capsule + raster cache once, decodes UTF-8 (C reimplementation mirroring capsules/fabric.4th's DECODE-UTF8 exactly), looks up each glyph's cached bitmap, blits via fb_put_pixel, advances the pen by the glyph's real hmtx advance width scaled to pixels. Necessary plumbing: ttf_parse() now also locates hhea/hmtx, and ttf_glyph_advance_width() reads a glyph's advance width -- required for this item's own "proportional spacing correct" acceptance clause, no advance-width data existed anywhere else in the parser. Verified in tools/ttftest.c: A/a/0/space all read advance_width=600, correctly uniform since JetBrainsMono-Regular.ttf is monospace. (x,y) is raster pixel space (top-left origin, Y-down), deliberately not the stroke font TEXT's Cartesian Y-up convention -- recorded explicitly in ttf_words.h, not conflated. Verified live, amd64, screendump: injected S" Hi 4.3.7e!" 200 200 28 16777215 TTF-TEXT over a serial socket after boot, no error, captured a screendump showing the string rendered legibly with correct mixed-case/digit/punctuation glyphs and even spacing. TTF-TEXT is this item's permanent deliverable, not a throwaway probe. Compile-checked clean on all three architectures. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
tools/
Build-time and integration-test utilities for the StarForth / LithosAnanke toolchain.
Contents
| File | Purpose |
|---|---|
mkcapsule.c |
Assembles .4th capsule files into capsule_generated.c baked into the kernel image. Invoked automatically by Makefile.starkernel. |
mkcapsule |
Compiled host binary (rebuilt on demand). |
fbtest.c |
Host framebuffer render test — VT100/framebuffer unit tests, no QEMU needed. |
pe_reloc_gen.py |
Generates PE32+ relocation tables for the UEFI loader. |
svg_to_png.py |
Renders every tracked .svg in the repo to a same-named .png via headless Chromium; leaves the source .svg untouched, run manually. |
hermes_smoke.sh |
Hermes v1 hosted smoke test — swaps in the Hermes init capsule and prints values for manual inspection. |
hermes_channel_smoke.sh |
Exercises the full Hermes channel-negotiation lifecycle (CH-REQUEST → CH-ACCEPT → CH-CLOSE → reap) per the protocol in .claude/HERMES.md. |
hermes_tripod_smoke.sh |
Full Tripod integration test — exercises all 6 inter-VM message paths using the DEFER VM-EXEC/IS VM-EXEC dispatcher shim from init.4th. |
kconfig/ |
Vendored Linux kernel Kconfig tooling (conf/mconf/qconf), GPL-2.0. See tools/kconfig/README.md. |
mkcapsule
# Invoked automatically by the kernel build:
make -f Makefile.starkernel ARCH=amd64 clean qemu
# Manual invocation (for inspection):
./tools/mkcapsule capsules/ build/amd64/kernel/capsule_generated.c
Scans capsules/ for .4th files, computes XXHash64 per capsule, assigns
type (m) to init.4th and (p) to everything else.
