@jgabriels thanks for the contribution. our test suite is stable on master if you would kindly rebase and add output fixtures and fix and linting issues. See #128 for inspiration.

@darrenjennings
I'm following this issue because @jgabriels and I just discussed it.
Has anything changed since your last comment in 2019, or is the process still the same?

@wbraswell No, this PR needs to be recreated under the new directory structure and TypeScript codebase.
