Instructions

You can build this template code using stack build according to the provided stack.yaml file. You can also use cabal if you prefer, as long as you can get the appropriate dependencies in place.

To use this template, first choose whether your program will use one command or more commands. For the multi-command version, use the src/OptParse.hs and test/OptParseSpec.hs files. Otherwise, use the src/OptParseOneCommand.hs and test/OptParseOneCommandSpec.hs files. Copy the modules into your project and follow instructions inside.

You can use template-filler to copy the template into your project, like this:

template-filler --source /path/to/the/OptParse.hs --destination /path/to/your/homeless/shelter/OptParse.hs --find FooBar --replace HomelessShelter

Run stack haddock to read the instructions in haddock form. Otherwise, continue reading in the source and the tests.
