Subject [jira] Commented: (CLI-199) Improve HelpFormatter by making renderOptions() and renderWrappedText() public
Date Fri, 11 Jun 2010 22:52:15 GMT

    [ https://issues.apache.org/jira/browse/CLI-199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12878121#action_12878121

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.

> 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.
