Rake is a Make-like program where tasks and dependencies are specified in standard Ruby syntax.

The coderake-compiler-dock gem provides a cross compiler environment for building gems on a variety of platforms (GNU/Linux, JRuby, Windows and Mac).

rubocop is a Ruby code style checking tool. It aims to enforce the community-driven Ruby Style Guide.

Sorcerer generates Ruby code from a Ripper-like abstract syntax tree (i.e. S-Expressions). Sorcerer is targeted mainly at small snippets of Ruby code, expressible in a single line. Longer examples may be re-sourced, but they will be rendered in a single-line format.

Minitest-hooks adds around, before_all, after_all, around_all hooks for Minitest. This allows, for instance, running each suite of specs inside a database transaction, running each spec inside its own savepoint inside that transaction. This can significantly speed up testing for specs that share expensive database setup code.

Diff::LCS computes the difference between two Enumerable sequences using the McIlroy-Hunt longest common subsequence (LCS) algorithm. It includes utilities to create a simple HTML diff output format and a standard diff-like tool.

This module provides a String#unindent Ruby method to unindent strings, which can be useful to unindent multiline strings embedded in already-indented code.

Rspec-expectations provides a simple API to express expected outcomes of a code example.

SimpleCov is a code coverage framework for Ruby with a powerful configuration library and automatic merging of coverage across test suites.

The Pagination Generator forms the core of the pagination logic in Jekyll. It calculates and generates the pagination pages.

GRPC is a high performance, open-source universal RPC framework. This package provides a ruby interface for it.

RubyProf is a fast code profiler for Ruby. Its features include:

Speed

Being a C extension, it is many times faster than the standard Ruby profiler.

Measurement Modes

It can measure program wall time, process time, object allocations and memory usage.

Reports

A variety of text and cross-referenced HTML reports can be generated.

Threads

Profiling multiple threads simultaneously is supported.

Net::SCP is a pure-Ruby implementation of the SCP client protocol.

Delayed_job (or DJ) encapsulates the common pattern of asynchronously executing longer tasks in the background. It is a direct extraction from Shopify where the job table is responsible for a multitude of core tasks.

Provides empty Module#ruby2_keywords method, for the forward source-level compatibility against ruby2.7 and ruby3.

Rubygems-task provides Rake tasks for managing and releasing Ruby Gems.

This gem provides parser dictionary data for AnyStyle.

Covered uses modern Ruby features to generate comprehensive coverage, including support for templates which are compiled into Ruby. It has the following features:

• Incremental coverage -- if you run your full test suite, and the run a subset, it will still report the correct coverage - so you can incrementally work on improving coverage.

• Integration with RSpec, Minitest, Travis & Coveralls - no need to configure anything - out of the box support for these platforms.

• It supports coverage of views -- templates compiled to Ruby code can be tracked for coverage reporting.

This package adds custom processing for warnings for Ruby, including the ability to ignore specific warning messages, ignore warnings in specific files/directories, include backtraces with warnings, treat warnings as errors, deduplicate warnings, and add custom handling for all warnings in specific files/directories.

EDTF-Ruby provides a parser and an API for the EDTF standard, implemented as an extension to Ruby's Date class.

This module allows Ruby programs to interface with the SQLite3 database engine.

Oj is a JSON parser and generator for Ruby, where the encoding and decoding of JSON is implemented as a C extension to Ruby.

This package provides methods for benchmarking Ruby code, giving detailed reports on the time taken for each task.

This package provides bindings for any kind of Ruby exceptions.
