Full description
@language-haskell-extract@ contains some useful helper functions on top of Template Haskell.
@functionExtractor@ extracts all functions after a regexp-pattern.
> foo = "test"
> boo = "testing"
> bar = $(functionExtractor "oo$")
will automagically extract the functions ending with @oo@ such as
> bar = [("foo",foo), ("boo",boo)]
This can be useful if you wish to extract all functions beginning with test (for a test-framework)
or all functions beginning with wc (for a web service).
@functionExtractorMap@ works like @functionsExtractor@ but applies a function over all function-pairs.
This functions is useful if the common return type of the functions is a type class.
Example:
> secondTypeclassTest =
> do let expected = ["45", "88.8", "\"hej\""]
> actual = $(functionExtractorMap "^tc" [|\n f -> show f|] )
> expected @=? actual
>
> tcInt :: Integer
> tcInt = 45
>
> tcDouble :: Double
> tcDouble = 88.8
>
> tcString :: String
> tcString = "hej"
