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: 1.2, 1.1, 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.
