Highline and Termios issues

[Ed Howland]

Hi,

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

agree("overwite #{path}? y/<%=3D color('N', BOLD) %>", true)
{|q| q.default =3D 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 =91Termios_to_termios=92:
termios.c:182: error: =91struct RArray=92 has no member named =91ptr=92

Thanks (Snow Leopard, BTW)

I have question re: Highline. In this code fragment, when running on = MacOS/X:
=20
agree("overwite #{path}? y/<%=3D color('N', BOLD) %>", true)
{|q| q.default =3D false}
=20
... The prompt is followed by a newline in irb/ruby. I can't see an
option in the docs to change this behavior.

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.
