bfcwasm is a brainfuck compiler targetting WebAssembly.
On macOS it is available in homebrew:
brew install chezscheme
If you don't have homebrew or are using Linux, it may be easier to build from
sources. You'll need development versions of the ncurses and libx11
libraries.
The compiler uses the nanopass framework, but it's already configured as a git submodule. To get it after cloning this repository:
git submodule init
git submodule update
After this you can compile programs using the script:
./compile.sh test/hello.bf
This will generate a bfprog.wat, a textual representation of the generated
WebAssembly program. The wabt tools are needed to transform it to a binary
module:
wat2wasm bfprog.wat -o bfprog.wasm
Now copy the generated bfprog.wasm and the HTML page runtime/bfprog.html
to the same directory, and open the HTML file in a browser with WebAssembly
support (the easiest is probably a recent Firefox). The page will show the
result of running the brainfuck program.
