Incomplete usage documentation about Java property option
---------------------------------------------------------
Key: CLI-154
URL: https://issues.apache.org/jira/browse/CLI-154
Project: Commons CLI
Issue Type: Bug
Components: CLI-1.x
Affects Versions: 1.1, 1.0, 1.2
Reporter: HAUTION Philippe
On Usage Scenarios page http://jakarta.apache.org/commons/cli/usage.html, in
the "Java property option" section of "Ant example", after the creation of the
property Option, ie :
Option property = OptionBuilder.withArgName( "property=value" )
.hasArg()
.withValueSeparator()
.withDescription( "use value for given
property" )
.create( "D" );
One should add :
property.setArgs(Option.UNLIMITED_VALUES);
for the example to work properly.
In the "Querying the commandline" section, the code line :
this.buildfile = line.getValue( "buildfile" );
should be :
this.buildfile = line.getOptionValue( "buildfile" );
Also some parsing code could be given about the special property option, for
instance :
Properties props = new Properties();
if( line.hasOption( "D" ) ) {
String[] args = line.getOptionValues( "D" );
for (int i = 0; i < args.length; i += 2) {
String propertyName = args[i];
String propertyValue = null;
if (i + 1 < args.length)
propertyValue = args[i + 1];
props.put(propertyName, propertyValue);
}
}
