Description: ------------ With nested subCommands, the help output is not quite right. Run the test script as ... test.php -h test.php update -h test.php update downgrade -h Essentially 2 issues. 1 - The script path is in the wrong place. 2 - The [args] text is not always present. Test script: --------------- <?php require_once 'Console/CommandLine.php'; $o_Parser = new Console_CommandLine(); $o_Command = $o_Parser->addCommand ( 'update', array ( 'description' => 'Update the given package', ) ); $o_Command->addCommand ( 'downgrade', array ( 'description' => 'Downgrade the given package', ) ); print_r($o_Parser->parse()); Expected result: ---------------- Usage: Z:\test.php [options] [args] Z:\test.php [options] <command> [options] [args] Options: -h, --help show this help message and exit Commands: update Update the given package Update the given package Usage: Z:\test.php [options] update [options] [args] Z:\test.php [options] update [options] <command> [options] [args] Options: -h, --help show this help message and exit Commands: downgrade Downgrade the given package Downgrade the given package Usage: Z:\test.php [options] update [options] downgrade [options] [args] Options: -h, --help show this help message and exit Actual result: -------------- Usage: Z:\test.php [options] Z:\test.php [options] <command> [options] [args] Options: -h, --help show this help message and exit Commands: update Update the given package Update the given package Usage: Z:\test.php [options] update [options] Z:\test.php [options] update [options] <command> [options] [args] Options: -h, --help show this help message and exit Commands: downgrade Downgrade the given package Downgrade the given package Usage: update [options] Z:\test.php [options] downgrade [options] Options: -h, --help show this help message and exit

>> 1 - The script path is in the wrong place. it seems that's a bug, I'll look at it. >> 2. The [args] text is not always present. I don't fully understand the problem, could you please send me the whole script, because in you're example, you don't have any args for the main parser, so it's normal that the [args] text is not displayed in the help message.

I didn't know [args] wasn't displayed. The script I've supplied DOES show [args] in some instances, even though I've not supplied any. The issue comes from showing help with sub-sub-commands. Maybe, limiting subcommands to 1 level.

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
