[jira] Commented: (CLI-199) Improve HelpFormatter by making renderOptions() and renderWrappedText() public

["Emmanuel Bourg (JIRA)" <ji...@apache.org>]

    [ 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.
