# COBOL -> WebAssembly proof of concept

This a proof of concept for building COBOL to WebAssembly

## How it works

1. Builds and installs the GNU Multiprecision Library [GMP](https://gmplib.org/) (dependency of GNUCOBOL)

1. Builds and installs [GnuCOBOL](https://www.gnu.org/software/gnucobol/)

1. Builds an LLVM bitcode version of GMP

1. Builds an LLVM bitcode version of libcob

1. Transpile COBOL source to C using GnuCOBOL

1. Build WebAssembly (and helper JS) using [emscripten](https://emscripten.org/), linking in the GMP and libcob bitcode

## Testing it out

The whole development environment is contained in the `.devContainer` directory.

Use Docker and the [containers remote extension](https://code.visualstudio.com/docs/remote/containers) for VSCode to reliably reproduce this environment
