if(File.directory?(full_name))
list full_name
end
}
end
puts ( list base_dir)
The return inside the block in the "list" method actually return from
the "list" method itself. But i just wanted to exit the block. how does
one exit from a block in ruby?

Why do you use "puts" here? As far as I can see you do the printing in #list.
The return inside the block in the "list" method actually return from
the "list" method itself. But i just wanted to exit the block. how does
one exit from a block in ruby?
please advise.
Not exactly the answer you were looking for, but...
def list base_dir, prefix
Dir.foreach(base_dir){|file|
if (file.eql? "." or file.eql? "..")
puts "break dosent work either"
break
end
# this if is the only solution i found, but its ugly.
if !(file.eql? "." or file.eql? "..")
puts "Got #{prefix+file.gsub(/.java$/,"")}" if file =~ /.*\.java$/
full_name = base_dir+"/"+file
if(File.directory?(full_name))
list full_name, prefix+file+"."
end
end
}
end
list "c:/java/", ""
break not only exited the block but also prevented execution with the
next file in the directory, break actually broke the foreach loop
entirely, I just wanted something like continue
please advise.
I am trying to recurse all directories and find certain type of files.

That would be "next". Note that exiting from a block and switching to
the next iteration is something completely different. You asked for
exiting and thusly were correctly referred to "break".

Thanks for clearing that up, I am thoroughly impressed with the ruby
community, best in world. Even professional support is slower.
I am a young convert from java
