1️⃣ Nomono

nomono standardizes local sibling-gem dependency loading for multi-repo setups.

It provides two Gemfile macros:

• nomono_gems(**opts) returns { gem_name => absolute_path }
• eval_nomono_gems(**opts) directly emits gem "name", path: "..."

The API mirrors existing *_local.gemfile patterns used in kettle-rb projects, but centralizes path/env logic in one reusable library.

Installation

Install the gem and add it to your Gemfile:

bundle add nomono

Or install directly:

gem install nomono

Usage

In your Gemfile (or a modular Gemfile loaded via eval_gemfile):

require "nomono/bundler"

local_gems = %w[
  kettle-dev
  kettle-test
  kettle-soup-cover
]

if ENV.fetch("KETTLE_RB_DEV", "false").casecmp("false").zero?
  # remote/released gems
  gem "kettle-soup-cover", require: false
else
  eval_nomono_gems(gems: local_gems, prefix: "KETTLE_RB")
end

Environment contract

By default (prefix: "NOMONO_GEMS"):

• NOMONO_GEMS_DEV controls local mode (false disables; true uses ~/src/kettle-rb; any other value is a path)
• NOMONO_GEMS_VENDORED_GEMS (or legacy VENDORED_GEMS) is a comma-delimited list of gems resolved from vendor dir
• NOMONO_GEMS_VENDOR_GEM_DIR (or legacy VENDOR_GEM_DIR) points at the vendor base path
• NOMONO_GEMS_DEBUG enables debug output

Override env variable names with options:

nomono_gems(
  gems: %w[rubocop-lts rubocop-ruby3_2],
  prefix: "RUBOCOP_LTS",
  path_env: "RUBOCOP_LTS_LOCAL",
  vendored_gems_env: "VENDORED_GEMS",
  vendor_gem_dir_env: "VENDOR_GEM_DIR",
  debug_env: "RUBOCOP_LTS_DEBUG"
)

Development

After checking out the repo, run bin/setup to install dependencies. Then run specs:

bundle exec rspec

To install locally:

bundle exec rake install
