Emmanuel Bourg updated CLI-37:
------------------------------
Fix Version/s: (was: 2.0)
1.2
> HelpFormatter does not wrap lines correctly after the second line
> -----------------------------------------------------------------
>
> Key: CLI-37
> URL: https://issues.apache.org/jira/browse/CLI-37
> Project: Commons CLI
> Issue Type: Bug
> Components: Help formatter
> Affects Versions: 1.0
> Reporter: Peter Kunszt
> Fix For: 1.2
>
>
> The HelpFormatter does not wrap the option lines
> correctly because the logic in renderWrappedText
> seems to be doubled up. on one side, padding is
> inserted of length nextLineTabStop for every line
> after the first, but then in findWrapPos this
> nextLineTabStop is ADDED to the width, resulting
> in lines rendered not of width, but nextLineTabStop + width.
> the following patch fixes this:
> --- old/HelpFormatter.java Wed Mar 5 18:02:18 2003
> +++ new/HelpFormatter.java Wed Mar 5 17:59:47 2003
> @@ -802,7 +802,7 @@
> while (true)
> {
> text = padding + text.substring(pos).trim();
> - pos = findWrapPos(text, width, nextLineTabStop);
> + pos = findWrapPos(text, width, 0);
> if (pos == -1)
> {
> however, this reduces the usage of findWrapPos to always
> using the third argument = 0 which makes most of its logic
> obsolete. it could be rewritten to be MUCH shorter. but maybe
> i'm just missing something.
> the output is fully satisfactory now.
