What this system is

This system is Rake, a build automation tool written in Ruby that manages tasks and dependencies. It provides a command-line interface for executing build scripts, supporting features like file-based tasks, Makefile-style dependency imports, and package creation. The project includes comprehensive documentation, a modular library structure, and a robust test suite to ensure reliability across various Ruby versions.

Features

Add comprehensive Rake documentation and examples

This change introduces a complete set of documentation files for the Rake build tool, including a detailed guide on command-line usage (\doc/command\_line\_usage.rdoc\) covering all available options and environment variables like \RAKEOPT\, a reference for the Rakefile format (\doc/rakefile.rdoc\) explaining tasks, file tasks, directory tasks, and multitasks, and a glossary (\doc/glossary.rdoc\) defining key concepts. It also adds example Rakefiles (\doc/example/Rakefile1\, \doc/example/Rakefile2\) demonstrating basic and Ruby-powered build patterns, along with supporting source files (\a.c\, \b.c\, \main.c\) and a historical prototype (\doc/proto\_rake.rdoc\) and rationale (\doc/rational.rdoc\) for the tool's design.

doc · high confidence

Added executable rake script

A new executable script at exe/rake has been added, allowing users to run Rake directly from the command line without needing to invoke it through the gem or bundle system. The script requires the rake library and runs the application, providing a standalone entry point for executing Rake tasks.

exe · high confidence

Added standard Rails binstubs for console, setup, and RuboCop

The project now includes executable scripts in the bin directory to streamline common development tasks. Users can run \bin/console\ to launch an interactive IRB session with the application environment loaded, \bin/setup\ to install dependencies via Bundler, and \bin/rubocop\ to lint the codebase. These binstubs ensure consistent execution contexts and simplify local environment configuration.

bin · high confidence

Initial project scaffolding and configuration

This change establishes the foundational structure for the Rake project by adding essential configuration and documentation files. It introduces a \.gitignore\ file to exclude build artifacts and IDE files, a \.rubocop.yml\ configuration to enforce Ruby 2.4+ coding standards, and a \CONTRIBUTING.rdoc\ guide for developers. Additionally, it provides the \MIT-LICENSE\, a comprehensive \README.rdoc\, and a \Rakefile\ that sets up the test suite and documentation generation tasks, effectively preparing the repository for development and distribution.

(repo-wide) · high confidence

Support for importing Makefile-style dependency files

Users can now import dependency information generated by Make's dependency tools (such as makedepend) into Rake tasks. A new MakefileLoader class parses .mf files, correctly handling escaped spaces and multiple targets per line, and registers itself to handle the 'mf' file extension via the import loader.

lib/rake/loaders · high confidence

Architecture

Rake library restructured into modular components

The Rake build tool has been refactored from a single monolithic file into a modular library structure. The main entry point now loads individual components such as the DSL definition, task management, file list handling, and Windows-specific utilities via relative requires. This change improves code organization and maintainability without altering the public API, as top-level constants like FileList and RakeFileUtils are still exposed for backward compatibility.

lib · high confidence

Behavioural changes

Rake 13.4.2 release

This update introduces Rake version 13.4.2, which includes a new \--debug-at-stop\ option to enable post-mortem debugging sessions when a task fails, and adds support for xz-compressed archives in \PackageTask\.

lib/rake · high confidence

Rake string extensions refactored into separate files

The Rake string extension methods (such as \ext\ and \pathmap\) have been reorganized into dedicated files (\lib/rake/ext/core.rb\ and \lib/rake/ext/string.rb\) with explicit \require\_relative\ dependencies. This structural change improves code modularity and readability but does not alter the functionality of the string extensions available to users.

lib/rake/ext · high confidence

Test coverage

Added test support infrastructure for Rake; Comprehensive test suite migration to minitest.

Dependencies

Add Gemfile and update rake.gemspec for modern Ruby development

The project now includes a Gemfile that declares development dependencies on test-unit, coveralls, rubocop, and rdoc, replacing the previous inline gemspec development dependency declarations. The rake.gemspec has been updated to require Ruby version 2.3 or higher, includes explicit metadata URIs for bug tracking, changelogs, documentation, and source code, and lists the gem's file structure explicitly.

Survey your own repository

ruby/rake was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.

About this page

  • The score is its most recent published measurement, taken on 19 September 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 8b4e8eb0da4bed60e3721167766a5c46ce7df32c — the exact code this score is about.
  • Scored under rubric-2026.09.15 — the same rubric and the same method as every other entry in this index.
  • Measured by watchdog.canine.dev using codehealth-analyzer preprod-13a154b7f5d1.
