Best way to develop vagrant plugins?

[Adam Feuer]

Hi,

What's the best way to develop a vagrant plugin? I have been following the documentation, and can install some plugins that are listed here:

https://github.com/mitchellh/vagrant/wiki/Available-Vagrant-Plugins

But I am having trouble figuring out how to develop my own plugin - it's not ready to be uploaded to the RubyGems repository. Ideally there would be a way to install the plugin directly from my source directory (or linked to it) so I wouldn't have to reinstall the plugin to run it. Is that possible? If so, how?

I tried installing the plugin using --plugin-source=file:///path/to/my/local/gem-repository - and it seems like the plugin starts to load, but then fails to load a dependency.

If it helps, here's the end of a debug log that shows the error... vagrant seems to find the repo, but can't resolve the 'git' dependency. I the git-1.2.5 gem is in the local repo (and of course on RubyGems), and I have run gem generate_index to create the index for the local repo...

Does anyone have any idea what's wrong?

Update:

Ok, by re-reading the instructions here:

http://docs.vagrantup.com/v2/plugins/packaging.html

I got the plugin installed by doing:

vagrant plugin install /path/to/plugin.gem

I think I now understand how to test the plugin using a Vagrant source installation too - I am going to try that next so I don't have to run the package and install over and over.

Update:

Ok, I can execute the plugin from its source directory using bundle exec, with a Vagrantfile that requires the plugin.
