Subject [jira] Commented: (CLI-199) Improve HelpFormatter by making renderOptions() and renderWrappedText() public
Date Sat, 12 Jun 2010 06:14:14 GMT


gg commented on CLI-199:

The assumption I made was not correct. Both rendering methods can stay protected as it would
colst too much effort to use them for gettig a nice looking output.
Nevertheless my requirement having help content rendered into a StringBuffer had to be solved.
So I added kind of an indirection to the printng exposing additional (public) rendering functions.
One can now decide if to print or to render into a SB.

Due to some strage behavior regarding the newLine usage renderHelp() is the only method which
may currently not be "generic".

I attached my version of the HelpFormatter to give you a better idea of the whole thing.

Cheers, Ulf

>            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.
