1️⃣ Nomono

if ci_badges.map(&:color).detect { it != "green"} ☝️ let me know, as I may have missed the discord notification.

if ci_badges.map(&:color).all? { it == "green"} 👇️ send money so I can do more of this. FLOSS maintenance is now my full-time job.

👣 How will this project approach the September 2025 hostile takeover of RubyGems? 🚑️

I've summarized my thoughts in [this blog post](https://dev.to/galtzo/hostile-takeover-of-rubygems-my-thoughts-5hlo).

🌻 Synopsis

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.

Compatibility

Compatible with MRI Ruby 3.2.0+, and concordant releases of JRuby, and TruffleRuby. CI workflows and Appraisals are generated for MRI Ruby 3.2.0+. This test floor is configured by ruby.test_minimum in .kettle-jem.yml and may be higher than the gem's runtime compatibility floor when legacy Rubies are not practical for the current toolchain.

✨ Installation

Install the gem and add to the application's Gemfile by executing:

bundle add nomono

If bundler is not being used to manage dependencies, install the gem by executing:

gem install nomono

⚙️ Configuration

Nomono has an environment contract. By default (prefix: "NOMONO_GEMS"):

NOMONO_GEMS_DEV controls local-path mode — tri-state:
- false / 0 / no / off (or unset) — no local gems; released gems are used (CI default)
- true / 1 / yes / on — workspace root is $HOME/src/kettle-rb
- Any other value — treated as an explicit workspace root path (/absolute/path used as-is; relative path prepended with $HOME)
NOMONO_GEMS_VENDORED_GEMS (or legacy VENDORED_GEMS) is a comma-delimited list of gem names resolved from a vendor directory. This is independent of NOMONO_GEMS_DEV — it applies when you have vendored copies of specific gems that should override both the workspace and released versions.
NOMONO_GEMS_VENDOR_GEM_DIR (or legacy VENDOR_GEM_DIR) is the base path of the vendor directory used for gems listed in NOMONO_GEMS_VENDORED_GEMS. Defaults to $workspace_root/vendor. This is not an alternative form of the workspace root — it only affects vendored gems.
NOMONO_GEMS_DEBUG enables debug output from nomono.

Examples

For example, in the kettle-rb family of gems, which nomono is a part of, the parameters used are prefix: "KETTLE_RB", path_env: "KETTLE_RB_DEV". This means that the following is true:

KETTLE_RB_DEV=false (or unset) — released gems from configured gem server (CI / single-gem development default)
KETTLE_RB_DEV=true — local sibling gems from $HOME/src/kettle-rb/<gem> (recommended for full-workspace development)
KETTLE_RB_DEV=/custom/path — local sibling gems from /custom/path/<gem> (non-standard workspace layout only)

You can override the env variable names via options. Here is an example for use with rubocop-lts gems:

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",
)

🔧 Basic 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

🤝 Contributing

If you need some ideas of where to help, you could work on adding more code coverage, or if it is already 💯 (see below) check issues or PRs, or use the gem and think about how it could be better.

We so if you make changes, remember to update it.

⭐️ Star History

📌 Versioning

This library follows for its public API where practical. For most applications, prefer the Pessimistic Version Constraint with two digits of precision.

For example:

spec.add_dependency("nomono", "~> 1.0")

📌 Is "Platform Support" part of the public API? More details inside.

Dropping support for a platform can be a breaking change for affected users. If a release changes supported platforms, it should be called out clearly in the changelog and versioned with that impact in mind. To get a better understanding of how SemVer is intended to work over a project's lifetime, read this article from the creator of SemVer: - ["Major Version Numbers are Not Sacred"][📌major-versions-not-sacred]

See CHANGELOG.md for a list of releases.

🤑 A request for help

Maintainers have teeth and need to pay their dentists. After getting laid off in an RIF in March, and encountering difficulty finding a new one, I began spending most of my time building open source tools. I'm hoping to be able to pay for my kids' health insurance this month, so if you value the work I am doing, I need your support. Please consider sponsoring me or the project.

Please give the project a star ⭐ ♥.

Thanks for RTFM. ☺️
