Jeweler and Gemcutter are my favorite tools for gem development now, thanks for making a screencast on this =)

Ryan,

Jeweler supports releasing to both Gemcutter and Rubyforge. The default is Github. See the options in the README

I see jeweler as too much for what is actually needed. http://github.com/sr/mg is "just enough" in that regard.

Excellent and timely screencast. I didn't know that you could use Jeweler with GemCutter (or RubyForge, for that matter). Thanks again!

Hey Ryan, thanks again for all the awesome casts!

Have you considered adding a captcha to your comment form? I'm getting sick of reporting all these spammers!

You have been such an inspiration to me over the last year and a half, and I really appreciate what you do for the rails community. Thanks for another valuable screencast!

Not Found

The requested URL /videos/183_gemcutter_and_jeweler.mov was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Ryan,

Great presentation. One question, how do you manage the version numbering with a VCS like svn, hg, git etc.? I'm just exploring Mecurial now, but with svn, I'd cp trunk to a tag. If I want to bump a version, there is no automated way to sync that with jeweler, I suspect.

I am currently looking into amp, which lets you customize a Mecurial setup. Maybe there is something that can be done there.

Amp would be a great idea for another Railscast... once it matures a little.

That's a nice demonstration and Gemcutter looks really neat. I also noticed that you can use "gem tumble" multiple times to cycle between different configurations.
