Examples of CmdLineParser

com.gitblit.utils.cli.CmdLineParser
Extended command line parser which handles --foo=value arguments.
The args4j package does not natively handle --foo=value and instead prefers to see --foo value on the command line. Many users are used to the GNU style --foo=value long option, so we convert from the GNU style format to the args4j style format prior to invoking args4j for parsing.

com.sanityinc.jargs.CmdLineParser
Largely GNU-compatible command-line options parser. Has short (-v) and long-form (--verbose) option support, and also allows options with associated values (-d 2, --debug 2, --debug=2). Option processing can be explicitly terminated by the argument '--'. @author Steve Purcell @author penSec.IT UG (haftungsbeschränkt) @version 2.0 @see com.sanityinc.jargs.examples.OptionTest

Option processing can be explicitly terminated by the argument '--'. @author Steve Purcell @version $Revision: 1.10 $ @see jargs.examples.gnu.OptionTest

org.molgenis.util.cmdline.CmdLineParser

This class defines the commandline options parser. Based on a class filled with members annotated with the Option annotation-type the parser knows for which minus parameters to look and to convert the accompanying string to which type. After the parse-function is finished the annotated object is filled with the data passed with the command-line options.

 class Example { class Options { \@Option(name="t", param="integer", type=Option.OptionType.REQUIRED_ARGUMENT, usage= "a long description here ...") public int threshold = 500; \@option(name="f", param="filename", type=Option.OptionType.REQUIRED_ARGUMENT, usage= "a long description here ...") public String file = "std_file.txt"; \@option(name="fs", param="filename-list comma separated", type=Option.OptionType.REQUIRED_ARGUMENT, usage= "a long description here ...") public Vector files = new Vector(); \@option(name="d", param="", type=Option.OptionType.NO_ARGUMENT, usage= "a long description here ...") public boolean do_something = false;  } public static void main(String args[]) { Example m = new Example(); Options options = m.new Options(); CmdLineParser parser = new CmdLineParser(options); try { parser.parse(args); } catch(CmdLineException e) { parser.printUsage(System.err, e.toString()); } if (options.do_something) { ... } } }

TODO Although some support is in place, methods are still not supported. TODO Help-output should be nicely formatted. TODO Make the program description also an annotated type ? @author RA Scheltema @version 1.0.0
