purescript-symbol-case

Functions for manipulating type level strings (symbols).

Overview

I'm not even sure if this library is useful but imagine you have an external endpoint with undesirable label format (e.g in snake case) and you'd like to have'em in camel case.

import Record (rename)

type MovieResponse =
  { id :: MovieId
  , title :: String
  , poster_path :: Maybe String
  , adult :: Boolean
  , overview :: String
  , release_date :: String
  , popularity :: Number
  , vote_count :: Number
  , vote_average :: Number
  }

response :: MovieResponse

camelCaseKeys = rename (SProxy :: _ "poster_path") (SProxy :: _ "posterPath")
  >>> rename (SProxy :: _ "release_date") (SProxy :: _ "releaseDate")
  >>> rename (SProxy :: _ "vote_count") (SProxy :: _ "voteCount")
  >>> rename (SProxy :: _ "vote_average") (SProxy :: _ "voteAverage")

desired = camelCaseKeys response

Instead of converting them manually by hand, you can make use of this library to automatically convert them for you.

import Record.Case (toCamelRecord)

desired = toCamelRecord response

⚠️ Limitation

Currently it supports only the ISO Latin Basic Alphabet (English letters). Suggestions and/or PRs are welcomed 🙂
