Emmanuel Bourg updated CLI-15:
------------------------------
Component/s: (was: CLI-2.x)
Help formatter
Environment: (was: Operating System: All
Platform: All)
Summary: HelpFormatter does not handle groups properly (was: [cli]
HelpFormatter does not handle groups properly)
> HelpFormatter does not handle groups properly
> ---------------------------------------------
>
> Key: CLI-15
> URL: https://issues.apache.org/jira/browse/CLI-15
> Project: Commons CLI
> Issue Type: Bug
> Components: Help formatter
> Affects Versions: 1.0
> Reporter: Etienne Pelletier
> Fix For: 2.0
>
> Attachments: HelpFormatter.java, Option.java
>
>
> The HelpFormatter repeats Options that have previously been printed with the
> group.
> The problem is in the else block where options not belonging to a group are
> printed. The code gets executed if it does not belong to a group -OR- if the
> group has already been printed.
> if( group != null && !list.contains(group)) {
> // this gets executed when a new group is found
> ...
> } else {
> // this gets executed if the group is OR ISN'T null, and if group is in
> list.
> ....
> }
> The else statement on line 267 should be as follows:
> } else if (group == null) {
> // This will make sure that options that have not been printed as part of a
> group
> // will not get printed again.
> ...
> }
> I believe this change fixes the problem.
> Also, the append on line 264 should add an extra space after the ] to make
> sure
> that there will be a space between the ] and the next option.
