stack commented on HADOOP-1375:
-------------------------------
Edward:
Looks like the the java wrapper around ReadLine is a popular solution for the
problem of navigating a shell command-line with arrow-keys: See groovy
http://www.nofluffjuststuff.com/blogs_speaker.jsp?speakerId=18 and jython
http://wiki.python.org/jython/ReadlineSetup. I tried it out and it manages the
up/down and left/right for you.
As per Owen's comment, you can't include the readline jar because of its
license. I'd suggest you do as for groovy and jython, and let the user compile
and install readline themselves if they want its functionality. You'll need to
do a little work to allow for an alternate console (as jython does). Default
readline console would be a noop that has the shell work as it currently does
but then if the user sets a system property to point at an alternate
implementation -- e.g. a GNU ReadLine install -- then you'd use it instead.
