CommandLineParser (Grace Framework

org.grails.build.parsing.CommandLineParser

```
public class CommandLineParser
extends Object
```
Command line parser that parses arguments to the command line. Written as a replacement for Commons CLI because it doesn't support unknown arguments and requires all arguments to be declared up front. It also doesn't support command options with hyphens. This class gets around those problems.

- Method Detail
  - public void addOption(String name, String description)
    
    Adds a declared option
    Parameters:
    name - The name of the option
    description - The description
  - protected DefaultCommandLine createCommandLine()
  - public static CommandLine getCurrentCommandLine()
  - public String getOptionsHelpMessage()
  - public CommandLine parse(String args)
    
    Parses the given list of command line arguments. Arguments starting with -D become system properties, arguments starting with -- or - become either declared or undeclared options. All other arguments are put into a list of remaining arguments
    Parameters:
    args - The arguments
    Returns:
    The command line state
  - public CommandLine parse(DefaultCommandLine cl, String[] args)
  - public CommandLine parseString(String string)
    
    Parses a string of all the command line options converting them into an array of arguments to pass to #parse(String..args)
    Parameters:
    string - The string
    Returns:
    The command line
  - public CommandLine parseString(String commandName, String args)
    
    Parses a string of all the command line options converting them into an array of arguments to pass to #parse(String..args)
    Parameters:
    commandName - The command name
    args - The string
    Returns:
    The command line
  - protected String processOption(DefaultCommandLine cl, String arg)
  - protected void processSystemArg(DefaultCommandLine cl, String arg)
  - public static String[] translateCommandline(String toProcess)
    
    Crack a command line.
    Parameters:
    toProcess - the command line to process.
    Returns:
    the command line broken into strings. An empty or null toProcess parameter results in a zero sized array.
