ramda reimplemented using fp-ts
npm install fp-ts-ramdaSome Ramda functions reimplemented using fp-ts.
Since the question "how do I implement x from Ramda in fp-ts" comes up pretty often
Each function should:
- be API compatible with the original Ramda function (as far as possible, see below)
- come with a property-based test to verify such compatibility (see other tests as an example)
- be typesafe (or even improve on the status of @types/ramda, if possible)
- come with a few typelevel tests (see other tests as an example)
- be non deprecated in Ramda
For some Ramda functions, 100% API compatibility is easy to obtain. For others (typically the ones relying on instances of some typeclass), it's difficult or nearly impossible without compromising type-safety.
All Ramda functions are "auto curried". Since an objective is to remain mostly API-compatible, translations must be curried too.
Each function should have a series of TS overloads making all the possible combinations of parameters well-typed, and be implemented using manual currying: see for instance adjust.ts.
Manual currying is preferred in order to avoid compromising perf, but might be revisited in the future.
A few things I haven't considered up to now and/or not sure how to handle:
- the R.__ placeholder
- "Acts as a transducer if a transformer is given..."
- "Dispatches to the X method of argument, if present."
