Best way to parse command-line parameters? [closed]

Answer 1

As everyone posted it's own solution here is mine, cause I wanted something easier to write for the user : https://gist.github.com/gwenzek/78355526e476e08bb34d

The gist contains a code file, plus a test file and a short example copied here:

import ***.ArgsOps._


object Example {
    val parser = ArgsOpsParser("--someInt|-i" -> 4, "--someFlag|-f", "--someWord" -> "hello")

    def main(args: Array[String]){
        val argsOps = parser <<| args
        val someInt : Int = argsOps("--someInt")
        val someFlag : Boolean = argsOps("--someFlag")
        val someWord : String = argsOps("--someWord")
        val otherArgs = argsOps.args

        foo(someWord, someInt, someFlag)
    }
}

There is not fancy options to force a variable to be in some bounds, cause I don't feel that the parser is the best place to do so.

Note : you can have as much alias as you want for a given variable.
