Java Simple Option parser is inspired from ruby OptParser class (rdoc/OptionParser). This work has been created as part of Semester Work on University of West Bohemia (zcu.cz).
Add java source files in to your project and import them in files in which you want to use them.
You can find usage in tests or in example bellow. JavaOpt class provides basic fluent interfaces for creating option definitions.
- Option - classic option (ex: -v, --verbose)
- Path/Expression - string or path after option fields
cd *path/expression*
cd ~/strnadj/Projects
cp *option* *path/expression* *path/expression*
cp -R ~/strnadj/Projects ~/strnadj/Projects_bacup/
We want basic ls command with options:
- Only files
- Only directories
- With hidden files
- Help
- And optional path
OptParser options = OptParser.createOptionParser("ls", "Show directory contents") .addOption('f', "files", OptParser.OPTIONAL, "", "Just files") .addOption('d', "directories", OptParser.OPTIONAL, "", "Just directories") .addOption('h', "help", OptParser.OPTIONAL, "", "Show this help") .addPathOrExpression("path", OptParser.OPTIONAL, ".", "Directory to listing");
.addOptionRequiredValue('t', "target", OptParser.OPTIONAL, null, "Target folder")
System.out.println(options.getHelp());
Usage: ls [options] "path" Optional options: -f, --files Just files -d, --directories Just directories -h, --help Show this help
try { options.parseArguments(args); } catch(Exception e) { System.err.println(e.getMessage()); System.exit(-1); }
// Get if parameter was set if (options.getOption("help") != null) { // Parameter help was set } // Values? if (options.getOption("directories") != null) { options.getOption("directories").value(); }
