Workflow

The normal workflow would go something like this....

1) Create a branch on the app-repo

Start in the repo for the application that needs the changes. (For example web or pnapi). Create a branch for your story changes.

2) Open the gem for editing

I am using invoca-metrics in this example.

bundle exec invoca_gem edit invoca-metrics

This will do the following:

• check out the invoca-metrics repo into invoca_gems/invoca_metrics.
• create a new branch on that repo starting at the sha from the app-repo Gemfile. The branch will use the same name as the app-repo.
• update the app-repo Gemfile to refer to the invoca metrics gem using a path.

3) Make your gem changes

At this point you can edit the invoca-metrics gem from the invoca_gems/invoca_metrics directory. You can confirm your changes work on the app-repo by running tests there.

4) Save your gem changes

When ready, save your changes to the invoca_metrics gem.

bundle exec invoca_gem save invoca-metrics --commit-message 'made some changes'

This can take a little while, so brace for it. This will do the following:

• Commit your changes to the invoca_metrics gem and push them to github.
• Update the app-repo Gemfile for the new version and sha of the invoca_metrics gem.
• Update any other invoca gems that depend invoca_metrics. For each of these gems it will:
  • Pull down the gem and create a branch at the sha from the app-repo.
  • Update the gem version of invoca_metrics in the gemspec.
  • Update the sha in the Gemfile for the dependent gem.
  • Bundle install to pick up the changes. (Takes a while.)
  • Commit the changes and push to github.
  • Update the app-repo gem to refer to the new sha.
• Bundle install the app-repo to pick up all the changes.

Whew.

5) Create pull requests

When ready you can view the changes and issue pull requests from github using the following command.

bundle exec invoca_gem show_changes

This will open a browser window showing all of the changed gems. From there you can open pull requests and confirm build results.

Other commands

Run the following to find available commands.

bundle exec invoca_gem

Installation

Add this line to your application's Gemfile as a development dependency:

group :development do
  gem 'invoca_gems'
end

And then execute:

$ bundle
