---------------------------------------------------------------------
Key: CLI-186
URL: https://issues.apache.org/jira/browse/CLI-186
Project: Commons CLI
Issue Type: Bug
Components: Help formatter
Affects Versions: 1.3
Environment: Mac OS X 10.5 Java 6, Windows XP Java 6
Reporter: Kristoff Kiefer
The generated help text will not show "<arg>" for the first argument added.
See following test case:
public void testArgsFormattingCorrect(){
Options options = new Options();
OptionBuilder.isRequired();
OptionBuilder.hasArg();
OptionBuilder.withDescription("Description");
OptionBuilder.withLongOpt("a-a");
options.addOption(OptionBuilder.create("a"));
OptionBuilder.isRequired();
OptionBuilder.hasArg();
OptionBuilder.withDescription("Description");
OptionBuilder.withLongOpt("b-b");
options.addOption(OptionBuilder.create("b"));
ByteArrayOutputStream out = new ByteArrayOutputStream();
HelpFormatter formatter = new HelpFormatter();
PrintWriter pw = new PrintWriter(out);
formatter.printHelp(pw, 80, "command", "", options, 0, 0, "");
pw.flush();
assertTrue(options.getOption("a").hasArg());
assertEquals("usage:
command\n-a,--a-a<arg>Description\n-b,--b-b <arg>Description\n",
out.toString());
}
