MultiRepo

MultiRepo is a tool for managing multiple git repositories.

gem install multi_repo

Typical usage will be from single scripts. In order to keep each script manageable, it can be preferable to use bundler/inline to define the gems needed by that script. To do this, add the following to the top of the script:

#/usr/bin/env ruby

require "bundler/inline"
gemfile do
  source "https://rubygems.org"
  gem "multi_repo", require: "multi_repo/cli"
end

Then, you would set up options for your script. A MultiRepo::CLI helper is provided to make this easier. It has the optimist gem already prepared and comes with a .common_options helper method to set up options for --repo-set, --repo, and --dry-run. For example,

opts = Optimist.options do
  opt :some_opt, "An option your script needs", :type => :string, :required => true

  MultiRepo::CLI.common_options(self)
end

would produce the following help output:

Options:
  -o, --some-opt=<s>    An option your script needs

Common Options:
  -s, --repo-set=<s>    The repo set to work with (default: master)
  -r, --repo=<s+>       Individual repo(s) to work with; Overrides --repo-set
  -d, --dry-run         Execute without making changes
  -h, --help            Show this message

After you have set up the options, you can write your script. MultiRepo::Service classes are provided to help interface with common third-party services, such as GitHub. MultiRepo::Helper classes are provided to do relatively common operations, such as renaming labels. The MultiRepo::CLI class also has helpers for looping over the repo set. For example, to loop over each repo in the repo set and show the file contents one can do:

MultiRepo::CLI.each_repo(**opts) do |repo|
  system("ls")
end

Certain commands interact with GitHub and expect a GitHub API Token set in the ENV variable GITHUB_API_TOKEN.

If you don't already have a token, or want to create one specific to these purposes

• Go to https://github.com/settings/tokens
• Choose "Generate New Token"
• Give the token a description
• At a mimimum, choose "repo" for the permissions.
• Click "Generate Token"
• Copy the token given to you, and keep it in a safe location, as once you leave the page, the token is no longer accessible

Then, in order to use it, export the ENV variable permanently, or pass it to the program as part of the call.

GITHUB_API_TOKEN=<token> bin/update_labels
