Slim Template
Template language to reduce the syntax to the essential parts
Slim is a Ruby template language whose goal is reduce the syntax to the essential parts without becoming cryptic. The initial design of Slim is what you see on the home page. It started as an exercise to see how much could be removed from a standard html template (<, >, closing tags, etc.). As more people took an interest in Slim, the functionality grew and so did the flexibility of the syntax. Slim will strive to maintain simplicity, but not everyone's definition of a readable syntax is the same. The docs will show you the options. Short syntax without closing tags (Using indentation instead) HTML style mode with closing tags. Slim is a fast, lightweight templating engine with support for Rails 3 and later. It has been heavily tested on all major ruby implementations. We use continuous integration (travis-ci). Slim uses Temple for parsing/compilation and is also integrated into Tilt, so it can be used together with Sinatra or plain Rack. -

Faraday
Simple, but flexible HTTP client library, with support for backends
Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters (such as Net::HTTP) and embraces the concept of Rack middleware when processing the request/response cycle. You probably don't want to use Faraday directly in your project, as it will lack an actual client library to perform requests. Instead, you probably want to have a look at Awesome Faraday for a list of available adapters. The best starting point is the Faraday Website, with its introduction and explanation. This library aims to support and is tested against the currently officially supported Ruby implementations. This means that, even without a major release, we could add or drop support for Ruby versions, following their EOL. Currently that means we support Ruby 2.6+. You can also install the faraday_middleware extension gem to access a collection of useful Faraday middleware. -

i18n-tasks
Manage translation and localization with static analysis, for Ruby i18
Manage translation and localization with static analysis, for Ruby i18n. i18n-tasks helps you find and manage missing and unused translations. This gem analyses code statically for key usages, such as I18n.t('some.key'), in order to report keys that are missing or unused. Pre-fill missing keys, optionally from Google Translate or DeepL Pro. Remove unused keys. Thus addressing the two main problems of i18n gem design, missing keys only blow up at runtime. i18n-tasks can be used with any project using the ruby i18n gem (default in Rails). i18n-tasks health checks if any keys are missing or not used, that interpolations variables are consistent across locales, and that all the locale files are normalized (auto-formatted). -

DevDocs
API Documentation Browser
The devdocs repository powers the DevDocs web application, a fast, offline-friendly documentation browser for many programming languages, libraries, and APIs. It aggregates documentation from multiple sources (e.g., MDN, Python, Ruby, Git, etc.), converts them into a uniform format, and indexes them for instant text searching. The codebase includes a backend that handles ingestion, parsing, and transformation of documentation sources into a static site structure, as well as the client side UI code for browsing, searching, and reading docs in a responsive interface. DevDocs supports offline usage: users can download sets of docs for use without an internet connection, benefiting from caching and compact compressed storage. The repository includes scripts for updating doc sources, building, and deploying the documentation site. Because it is meant as a reference tool, performance and usability (e.g. fast search, minimal latency) are emphasized in design. -

Homebrew Core
Default formulae for the missing package manager for macOS (or Linux)
Homebrew-core is the canonical formula repository for Homebrew, the macOS (and Linux) package manager, containing the Ruby “formulae” that describe how to fetch, build, and install thousands of open-source packages. Each formula encodes metadata, dependencies, build instructions, and tests so Homebrew can produce reproducible bottles (prebuilt binaries) or source builds across supported macOS and Linux environments. The repo is the operational center for package maintenance: maintainers review updates, address compatibility patches, and manage version migrations and deprecations to keep the ecosystem healthy. When users install or upgrade packages, Homebrew leverages the core formulae to resolve dependencies, perform sandboxed builds, and run post-install hooks, making development toolchains and end-user apps easy to provision.
