Hello, fellow ruby enthusiasts! I'm a first time caller, long time listener. Does highline allow you to send the "ask" prompt to STDERR? I often times use it to prompt for passwords in command line tools that I want to pipe to less or more. The problem is that if I pipe it to less or more I never see the password prompt, and I believe the usual workaround is to send the password prompt to STDERR to get around this. Any ideas? - Thanks!

Glad you decided to join us. > Does highline allow you to send the "ask" prompt to STDERR? Sure. If using the import interface, you can do it like this: $terminal = HighLine.new($stdin, $stderr) ask( … ) Otherwise, you can just build the proper HighLine instance and use it: hl = HighLine.new($stdin, $stderr) hl.ask( … ) Hope that helps.

So if you want to have an interactive filter in a pipeline, that reads from stdin and writes to stdout, you can have it do all of it's interaction (both ways) on stderr to read from the terminal. That's how `vim -' works --Ken
