A simple command line argument parser.

Usage:

1. Define parameters with param, requiredParam, repeatedParam and command. Each of these methods gives back a handle to a future argument value.

2. Call parse() with actual arguments.

3. If parsing succeeds, the arguments will be available in the handles defined in step 1.

If parsing fails, error descriptions are printed and the program exits with 2. (This behaviour may be changed by subclassing and redefining the check() method).

Example

val parser = argparse.ArgumentParser("0.1.0")

val p1 = parser.param[String]("--this-is-a-named-param", default = "default value")
val p2 = parser.param[Int]("positional-param", default = 2)

parser.parse(Seq("--this-is-a-named-param=other", 5)) println(p1())

println(p2())

A typeclass that defines how to convert a string from a single command line argument to a given type.

The name of the flag to use for generating standalone bash-completion.

Set this to the empty string to disable bash-completion entirely.

Generate a help message from parameters.
