Preinstall ruby-debug and rcov?

[Charles Oliver Nutter-4]

Hey, I was thinking yesterday it would be nice to preinstall some of
the tools a lot of people end up using like ruby-debug and rcov. Any
objections to something like this?

I've already committed adba60c which installs the ruby-debug bits
during our build. This allows you to jruby --debug -S rdebug a script
right away with a JRuby install. I'm debating if we'd want to merge it
to 1.4 or not.

Thoughts?

I think that would be great.

The 2 step I have to go through to install rdebug with jruby was
always a little bit cumbersome... This would be superfantastic.

So long as they are gems I don't see how it could harm anything other
than download size.  Honestly, these are probably pretty tiny in the
grand scheme of things.

I can see how it would be helpful to folks that use them but will it create a headache for folks that want a minimal JRuby install?

I'd use it, and the tools you mentioned are not too heavy, but it might create a little confusion too depending on the implementation.  Were you thinking of "j___" versions of any binaries (as, e.g. jirb, so jrcov ...)?  Or keep the native names?

Anti-bloat is a good principle too, and this might be the first wiggly rock on a slippery slope.

I guess my first preference would be to avoid direct packaging, but include some useful scripts that can quickly bootstrap suites of useful gems that work well with JRuby.  For example, I am making a lot of Rails apps under JRuby so I keep having to install rails, jdbc-* drivers, jruby-rack, and the lot; this pile is certainly not lightweight, but I want it instantly within reach after installing jruby (so I have my own little script...).  Especially in cases where the JRuby gem stack requires some changes from C ruby idiom, this easy bootstrapping could save first time JRuby adopters a lot of digging, and grizzled veterans a lot of repetition.

I'm also thinking here of what my Ubuntu boxen do when I type a command but forgot to install the corresponding package:

The program 'xpdf' is currently not installed.  You can install it by typing:

apt-get install xpdf-reader

I always like those reminders.  Saves me on long-term memory storage.

I like this idea a lot. Would meta-gems that are basically empty gems
+ dependencies work? For example:

jruby-essential:
  - jruby-openssl
  - jruby debug stuff

jruby-rails:
  - activerecord-jdbcmysql-adapter
  - activerecord-jdbcsqlite3-adapter
  - rails
  - warbler
  - mongrel or glassfish
  - json-jruby ?

Other ideas? Maybe 'jruby-dev' or 'jruby-testing' gems?
