Twelf is an implementation, in Standard ML, of a logical framework based on the type theory LF.
Inspired by Twelf Live, and thanks to this PR against the MLton compiler, which adds a cross-compilation target for Wasm/WASI, you can now run twelf inside your browser.
Go here to interact with the twelf server.
From a fresh checkout, you can do
npm install
make build
make serveto serve locally on port 8000.
Alternatively the default build target
make
runs a watch process, continually rebuilding javascript from typescript source.
make wasmrebuilds the twelf.wasm asset in docker. This artefact is also checked into the repository,
and it similarly does not need to be built from a fresh checkout.
make deploypushes to the deploy branch, which causes this Actions workflow to rebuild the static site.
make publishpushes to the publish branch, which causes this Actions workflow to publish the npm package.
