IRB for mac

ruby-talk
1

In the terminal there seems to be problem with the arrow keys.
When pressing arrow_left then I see ^[[D in the terminal.
pressing CTRL-A doesn't work neither.
I suspect the escape sequences isn't being read correct.

What is the solution for this?

btw: I am learning about Cocoa on mac and figured it would be
interesting to write a GUI frontend for IRB. Something like this:
http://aeditor.rubyforge.org/data/mac_irb1.png

I wonder how I can establish communication with irb.
I am in paticular curious to how/if the freeride team has done it.

Install the readline extension - see list archives.

In FreeRIDE, we are using Martin DeMello's FXIrb:

You could take a look and see what he is doing.

I suspect Ruby did not link against the readline library when installing. I always install GNU Readline on OX X before I build Ruby. I can use the arrow keys in irb normally, but my .irbrc file contains:

require 'irb/completion'
ARGV.concat [ "--readline" ]

Might try "irb --readline".

I'm completely guessing here and way out of my area though, so maybe on of the gurus will have better advice...

Good luck.

I wasn't aware of FXIrb, nice. Thanks.

I am wondering how to make my Cocoa project into a ruby-extension,
so that I can require it from Ruby (so that main is in Ruby).
Any ideas on this ?

Thanks, I should have known that a week ago :slight_smile:

I just realized that there exists a binary installer for ruby 1.8.2, that has
readline with it. The reason why I overlooked it the first time, was
because I didn't knew what a .dmg file was.

I will try it out.
