web-sw-cor24-fortran

Browser-based FORTRAN hello-world demo for the COR24-TB p-code virtual machine.

Live demo: https://sw-embed.github.io/web-sw-cor24-fortran/

What this is

A small Yew/WASM page that embeds the COR24 emulator and runs a pre-built examples/hello.lgo produced upstream by sw-cor24-fortran (the SNOBOL4-based FTI-0 Fortran compiler). The page shows the hello.f source on the left and the program's UART output on the right.

This repo is intentionally narrow: a single hello-world demo, no in-browser compiler, no editor. The Trunk + Yew shape is reusable for future Fortran demos as the upstream compiler matures.

Pipeline

hello.f                     <- examples/hello.f (FORTRAN source)
   |
   v  sw-cor24-fortran  (SNOBOL4)
hello.s                     <- COR24 assembly
   |
   v  cor24-asm
hello.lgo                   <- examples/hello.lgo (loadable object)
   |
   v  cor24-emulator (compiled to WASM)
"Hello, World!"             <- this page

Building locally

You need Trunk and a Rust toolchain with the wasm32-unknown-unknown target.

# Sibling path-deps (cor24-emulator + cor24-isa) must be checked out
# next to this repo. From your sw-embed/ workspace root:
[ -d sw-cor24-emulator ] || git clone <bare>/sw-cor24-emulator.git
[ -d sw-cor24-isa ]      || git clone <bare>/sw-cor24-isa.git

cd web-sw-cor24-fortran
./scripts/serve.sh       # http://127.0.0.1:8414/

Deploying

./scripts/build-pages.sh   # writes to pages/
git add pages/ && git commit -m "Deploy: rebuild pages/"
git push

.github/workflows/pages.yml deploys pages/ on push to main. A pages/.nojekyll marker is committed so GitHub Pages serves the WASM and JS shim files directly without Jekyll preprocessing.
