Emmanuel Bourg commented on CLI-199:
------------------------------------
Could you give an example of the processing you do on the output of the
HelpFormatter? With the current API you should be able to achieve the same
result with a StringWriter inside a PrintWriter.
> Improve HelpFormatter by making renderOptions() and renderWrappedText() public
> ------------------------------------------------------------------------------
>
> Key: CLI-199
> URL: https://issues.apache.org/jira/browse/CLI-199
> Project: Commons CLI
> Issue Type: Improvement
> Components: CLI-1.x
> Affects Versions: 1.1, 1.2, 1.3
> Reporter: gg
> Priority: Trivial
>
> Under certain circumstances it is usefull that HelpFormatter printing methods
> return a string buffer which can be used in further processing instead of
> direct printing to a PW or std.out.
> When having a closer look at the source one can easily retrieve string
> buffers with formatted text by changing the visibility of renderOptions() and
> renderWrappedText() from protected to public. This will make the "core"
> formatting methods available without adding additional functionallity to the
> HelpFormatter.
> Another option would be to add a set of print....() methods returning the SB
> instead of printing its content.
