CliOption

Synopsis

- data Option
  - = FileOption String String
  - | Option String
- showOpt :: Option -> String

# Documentation

data Option Source #

When invoking external tools as part of the compilation pipeline, we pass these a sequence of options on the command-line. Rather than just using a list of Strings, we use a type that allows us to distinguish between filepaths and 'other stuff'. The reason for this is that this type gives us a handle on transforming filenames, and filenames only, to whatever format they're expected to be on a particular platform.
