Highline and Termios issues

ruby-talk

Hi,

I have question re: Highline. In this code fragment, when running on MacOS/X:

        agree("overwite #{path}? y/<%= color('N', BOLD) %>", true)
{|q| q.default = false}

... The prompt is followed by a newline in irb/ruby. I can't see an
option in the docs to change this behavior. I'm trying to emulate the
question when copying a directory tree like the Rails command or its
generators do.

Some searching led me to think that the Termios gem may help, but if I
try to install it (Ruby 1.9.2-p0), I get this:

termios.c: In function ‘Termios_to_termios’:
termios.c:182: error: ‘struct RArray’ has no member named ‘ptr’

Thanks (Snow Leopard, BTW)

Cheers,

You just want to take the answer on the same line? Add some space after the prompt (at the end of your bold N) and HighLine should do the right thing for you.

Hope that helps.
