🍲 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.

I've summarized my thoughts in this blog post.

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.

Available as part of the Tidelift Subscription.

The maintainers of this and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source packages you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact packages you use.

• 💡Subscribe for support guarantees covering all your FLOSS dependencies
• 💡Tidelift is part of Sonar
• 💡Tidelift pays maintainers to maintain the software you depend on!
  📊@Pointy Haired Boss: An enterprise support subscription is "never gonna let you down", and supports open source maintainers

Alternatively:

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

This gem is cryptographically signed and has verifiable SHA-256 and SHA-512 checksums by stone_checksums. Be sure the gem you install hasn’t been tampered with by following the instructions below.

Add my public key (if you haven’t already; key expires 2045-04-29) as a trusted certificate:

gem cert --add <(curl -Ls https://raw.github.com/galtzo-floss/certs/main/pboling.pem)

You only need to do that once. Then proceed to install with:

gem install nomono -P HighSecurity

The HighSecurity trust profile will verify signed gems, and not allow the installation of unsigned dependencies.

If you want to up your security game full-time:

bundle config set --global trust-policy MediumSecurity

MediumSecurity instead of HighSecurity is necessary if not all the gems you use are signed.

NOTE: Be prepared to track down certs for signed gems and add them the same way you added mine.

Nomono has an 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",
)

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

While kettle-rb tools are free software and will always be, the project would benefit immensely from some funding. Raising a monthly budget of... "dollars" would make the project more sustainable.

We welcome both individual and corporate sponsors! We also offer a wide array of funding channels to account for your preferences (although currently Open Collective is our preferred funding platform).

If you're working in a company that's making significant use of kettle-rb tools we'd appreciate it if you suggest to your company to become a kettle-rb sponsor.

You can support the development of kettle-rb tools via GitHub Sponsors, Liberapay, PayPal, Open Collective and Tidelift.

Support us with a monthly donation and help us continue our activities. [Become a backer]

I’m driven by a passion to foster a thriving open-source community – a space where people can tackle complex problems, no matter how small. Revitalizing libraries that have fallen into disrepair, and building new libraries focused on solving real-world challenges, are my passions. I was recently affected by layoffs, and the tech jobs market is unwelcoming. I’m reaching out here because your support would significantly aid my efforts to provide for my family, and my farm (11 🐔 chickens, 2 🐶 dogs, 3 🐰 rabbits, 8 🐈‍ cats).

If you work at a company that uses my work, please encourage them to support me as a corporate sponsor. My work on gems you use might show up in bundle fund.

I’m developing a new library, floss_funding, designed to empower open-source developers like myself to get paid for the work we do, in a sustainable way. Please give it a look.

Floss-Funding.dev: 👉️ No network calls. 👉️ No tracking. 👉️ No oversight. 👉️ Minimal crypto hashing. 💡 Easily disabled nags

See SECURITY.md.

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 reek, 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.

This Library adheres to . Violations of this scheme should be reported as bugs. Specifically, if a minor or patch version is released that breaks backward compatibility, a new version should be immediately released that restores compatibility. Breaking changes to the public API will only be introduced with new major versions.

dropping support for a platform is both obviously and objectively a breaking change
—Jordan Harband (@ljharb, maintainer of SemVer) in SemVer issue 716

I understand that policy doesn't work universally ("exceptions to every rule!"), but it is the policy here. As such, in many cases it is good to specify a dependency on this library using the Pessimistic Version Constraint with two digits of precision.

For example:

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

SemVer should, IMO, but doesn't explicitly, say that dropping support for specific Platforms is a breaking change to an API, and for that reason the bike shedding is endless.

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:

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.
