~~~~ListBrowser README~~~~

I was working on a parser for a very specific tree structure, and was  
frustrated  
that there wasn’t a simple way to parse it in irb. “What??”, I thought.  
“I have  
to use my brain?! God forbid!”.  
So I set to using my brain a little more to create this tool. It’s not  
much,  
but maybe it’ll make someone’s life a little easier.

It can be used in irb, and really should be used there - when you call  
it on  
a tree structure, you’ll get a menu with a list of choices on how you  
want to  
go through whatever structure you gave it.

In my particular, special case, I would do something like this:

require ‘sgf\_parser’ # For my tree structure  
require ‘list\_browser’ # For this.

tree = SgfParser::Tree.new :filename =\> “kogo.sgf”

ListBrowser.new tree.root, ‘parent’, ‘children’, ‘properties’

# And follow the menu!

In my particular case, I would not need to enter those strings, as they  
just happen to be the names I chose for my tree structure, but they  
should  
serve as a good enough example!

Right. As I was saying…  
If you have gemcutter installed, just do:  
gem install ListBrowser

And you’re set!
