Question

I’m using Bundler for the gem dependency management.

Is there a way to get a notification when a new gem of a gem specified in Gemfile available?

Answer 1

According to “Can bundler show me which gems in Gemfile have newer versions (eg. dry-run of bundle update)” topic – there is no direct way to do it.

As a workaround if you use version controll just invoke bundler update print diff of Gemfile.lock (against version from repo) and revert it back.

Update Jun 2012: as of bundler 1.1 there is new command option bundle outdated – it prints nicely what are installed and latest versions of gems:

$ bundle outdated
Fetching gem metadata from http://rubygems.org/.......

Outdated gems included in the bundle:
  * multi_json (1.3.6 > 1.1.0)
  * activesupport (3.2.6 > 3.2.1)
  * activemodel (3.2.6 > 3.2.1)
  * journey (1.0.4 > 1.0.3)
...

Thanks Shaun.
