cool! i don't know if it's your end goal or not, but this could make it possible to test flowconfig in Try Flow. (aside: if your goal is to allow config changes in Try Flow, flowconfig isn't necessary, we can discuss further)

this is AGPL-3+, and the part based on strstubs.c is LGPL2 + static linking exception. we will have to review license compatibility...

without looking into how hard it'd be first, i'd be more inclined to remove the uses of Str instead. might even make sense to use a real parser (we already depend on sedlex and ocamllex) but that's a bigger project.

Thanks, I'll remove it for now, I think LGPL2 is compatible with MIT, not sure about AGPL3

Str also would be useful for flow.js overall, not just flowconfig parser

It was fixed, but I know that Flow uses old js_of_ocaml

I'm not sure about specific goal, I heard that babel needed flowconfig parsing for all option, also this can incorporate flow init but accept js objects instead of CLI

@mroch I think LICENSE was updated

Files: coq-js/js_stub/str.js
License: LGPL2.1
Comment: Derived from OCaml (https://github.com/ocaml/ocaml).

Is this still doesn't work with MIT?

My goal is to allow any js tool to write or read flowconfig, related #7771

/cc @mroch does LICENSE still bad one? It is LGPL2.1 now

sign = 0 is not correct.

Closing since there are license issues, and we already have support for flowconfig in try-flow
