How to upgrade to v12 in monorepo?
I figured that when I run npm exec -- rescript build from the root, it uses v11 for whatever reason. I’m going to clean this mess up so the repo only has v12 and report back on what’s going on when I...

Hello! I am making a ledger app for myself, and am puzzled with finding the proper transformation after lexer and parser steps into the app logic. I provide the part of text / types which are relevant...

Then you should probably reduce to option<t>: let make: array<ParserResult.t> => option<t> = lines => lines->Array.reduce(None, (ledger, parserResult) =>...

if you want the validation to be in a subsequent stage, making all the record field optional would make sense then, wouldn’t it? You’d then have a “validated” ledger settings record that you could...

I played with this last week. Some feedback: This should also work for Null.t and Nullable.t. It would be more ergonomic if we could mix various types. For example: let updateH2Color2 = () => {...

Could you do me a favor and try this script: gist.github.com/nojaf/f3c26f2354b1609366bb51c59bfed20e Does it find the correct @rescript/runtime folder in a reasonable time?
