named: Named parameters (keyword arguments) for Haskell
named
is a lightweight library for named function parameters (keyword
arguments) based on overloaded labels. Keyword arguments have several
advantages over positional arguments:
they can be supplied in arbitrary order
their names serve as documentation at call site
it is impossible to accidentally mix them up
Unlike newtype
wrappers, keyword arguments don't pollute the global
namespace, don't require top-level definitions, and don't need to be
exported.
This implementation of named parameters is typesafe, provides good type inference, descriptive type errors, and has no runtime overhead.
Example usage:
import Named createSymLink :: "from" :! FilePath -> "to" :! FilePath -> IO () createSymLink (Arg from) (Arg to) = ... main = createSymLink ! #from "/path/to/source" ! #to "/target/path"
