Installation

Make sure you have Elixir installed. If you’re on a Mac, just run brew install elixir

Run mix deps.get and mix escript.build or combine them as mix do deps.get, escript.build

• mix deps.get: Download the dependencies defined inside mix.exs
• mix escript.build: Build the executable that can be invoked from the command line

Usage

With compiled binary:

$ echo -e "fork\nstar" | ./prepend "Give a "
Give a fork
Give a star

Or run prepend directly via mix task

$ echo -e "fork\nstar" | mix prepend "Give a "
Give a fork
Give a star

Development

• Start mix test.watch and develop TDD or run tests only once with mix test
• Property tests can be run with mix test --only property
• To give the code a try in the REPL use iex -S mix and try the this:

["one", "two"] |> Prepend.stream_lines("$ ") |> Enum.to_list

• Format code using mix format
• Lint code using mix credo and mix dialyzer
