Commandline options and output-"method"

Ruby
1

I’ve got two questions:

Is it possible to run a ruby script with options? i.e.:
foobar.rb --someoption
foobar.rb -o

secondly,
(how) is it possible to change the output of a script to a static
output, so you only update a part of it? Like the progressbar of wget,
for example.

Yes - they appear in the ARGV array, and can be parsed with one of a
number of tools, eg OptionParser which is in the standard library.

You need to output ANSI terminal control characters, which you probably
also want to do through a library - ProgressBar is a simple tool if you
actually want a progress bar, otherwise you might like to look at the
Ruby ncurses bindings for more advanced applications.

Thanks

well, its not a progressbar that I need. Do you know where I can find
some good Tutorials fur ruby ncurses?

there is absolutely no documentation about the ncurses-ruby lib out
there. And porting C-examples to ruby doesnt really work.

Is there an other way or lib to create GUI-like terminal apps?
