REE is installed with wrong/no readline

[jjb]

for REE, when I paste into irb or pry, the characters come in very slowly. it's the problem described here:

• http://stackoverflow.com/questions/7296169/pasting-text-into-irb-is-incredibly-slow-readline-issue
• http://stackoverflow.com/questions/5624740/rails-console-running-incredibly-slowly-when-editing-text

I'm working on a ruby-build solution for this now (although I'm not exactly sure what that is -- the discussions at those questions and elsewhere on the web is never quite clear about what the cause is -- a particular version of readline? I'm going to look at the RVM solution)

Is it worth fixing at the ruby-build level? Have others experience this problem? I'm on 10.6.8

Alright i'm done hacking around with this for tonight, I didn't make any progress installing readline from source. Tomorrow (translation: in a month) I should try using rvm to install readline, and then point ruby-build at it (with -c --with-readline-dir=/foo/bar/baz added to options in share/ruby-build/ree-1.8.7-2011.03)

I patched ruby-build to support $CONFIGURE_OPTS in REE definitions. (See tessro/ruby-build@cf35539)

This worked for me (on OS X 10.7):

CONFIGURE_OPTS="-c --enable-shared -c --with-readline-dir=/usr/local/Cellar/readline/6.2.1/" ruby-build ree-1.8.7-2011.03 ~/.rbenv/versions/ree-1.8.7-2011.03/

nice -- and now you don't have the "slow paste" problem?

[tessro]

I thought this issue was resolved for me, but I can in fact replicate it on my machine. Bummer.

FWIW, this happens in both REE 1.8.6 and REE 1.8.7 when configured with Readline. AFAIK, RVM doesn't install Readline by default which is why this doesn't show up there.

I think this is the relevant patch from RVM:

https://github.com/wayneeseguin/rvm/blob/master/patches/ruby/1.8.7/readline-fix.diff

I'll test it locally when I have a bit more time.

I don't think we want to get into the business of applying patches willy-nilly like RVM. Feel free to pass along whatever you want to $CONFIGURE_OPTS now, though.
