README
harg :nut_and_bolt:
harg
is a library for configuring programs by scanning command line arguments,
environment variables, default values and more. Under the hood, it uses a subset
of optparse-applicative
to expose regular arguments, switch arguments and subcommands. The library
relies heavily on the use of higher kinded data (HKD) thanks to the
barbies
library. Using
higgledy
also helps reduce
boilerplate code significantly.
Documentation
To find out more, check out the docs or the package page on hackage. There is also an example module that serves as an extensive demonstration of the library.
