Takes an environment variable list and all the name mappings and prepares a set of environment variables according to the RichEnv rules.

>>> mappingsToValues [("FOO", "bar"), ("SOME", "thing")] (Mappings $ HM.fromList [("OTHER", "FOO")])
Values {unValues = fromList [("OTHER","bar")]}

Takes an environment variable list and all the prefix mappings and prepares a set of environment variables according to the RichEnv rules.

>>> prefixesToValues [("FOO", "bar"), ("SOME", "thing")] (Prefixes $ HM.fromList [("OTHER", ["FOO"])])
Values {unValues = fromList [("OTHER","bar")]}

Takes a Values object and sets its contents as environment variables.

Takes a Values object and transforms it into a list of key-value pairs representing environment variables.

valuesToEnvList = Data.HashMap.Strict.toList . unValues

Takes an environment variable list and a RichEnv object and generates a Values object.

>>> richEnvToValues RichEnv.Types.defaultRichEnv [("FOO", "bar"), ("SOME", "thing")]
Values {unValues = fromList []}

>>> import RichEnv.Types.Values as V
>>> let richEnvValue = RichEnv.Types.defaultRichEnv { values = V.fromList [("OTHER", "var")]}
>>> let envList = [("FOO", "bar"), ("SOME", "thing")]
>>> richEnvToValues richEnvValue envList
Values {unValues = fromList [("OTHER","var")]}

>>> import RichEnv.Types.Mappings as M
>>> let richEnvValue = RichEnv.Types.defaultRichEnv { mappings = M.fromList [("SOME", "FOO")]}
>>> let envList = [("FOO", "bar"), ("SOME", "thing"), ("SOME", "other")]
>>> richEnvToValues richEnvValue envList
Values {unValues = fromList [("SOME","bar")]}

>>> import RichEnv.Types.Prefixes as P
>>> let richEnvValue = RichEnv.Types.defaultRichEnv { prefixes = P.fromList [("NEW_", ["PREFIXED_"])]}
>>> let envList = [("PREFIXED_VAR", "content"), ("PREFIXED_VAR2", "content2")]
>>> richEnvToValues richEnvValue envList
Values {unValues = fromList [("NEW_VAR","content"),("NEW_VAR2","content2")]}
