Ephemeral brings ORM-like functionality to non-persisted Ruby objects. The anticipated use case is for an application that consumes an API and materializes one or more collections of objects from a JSON response or XML response. Another frequent use involves providing relations and scopes to POROs (plain old Ruby objects).
Society analyzes and presents a social graph of relationships between classes in a Ruby or Rails project. It shows both afferent and efferent coupling in a stunning visual graph. You can click on class names to filter the data and focus on couplings (inbound and outbound) related to a given class.
PoroPlus is a tiny Ruby gem that provides friendly methods intended to make POROs (Plain Old Ruby Objects) more useful, most notably by adding intelligent initializers that auto-map to defined attributes.
(Work in progress!) Revenant is a gem that is designed to find dead code in Ruby applications. This is a difficult problem in a dynamic language, since static analysis of the abstract syntax tree (AST) is impossible. As a result the output of the gem will represent "best guesses" about methods that seem to be unused, which when combined with human investigation and instinct can inform a code cleanup effort.
Test run times can be a valuable measure of code quality and the overall health of your development efforts. Long test run times are a sign that TDD is getting more difficult (or ignored), and a test suite that is getting longer over time is a symptom of best testing practices multiplying and spreading. This custom Rspec formatters sends test execution times to a statsd server for tracking your test executions over time.
Ambient Spec is a unique Rspec and Minitest formatter that turns your test output into soothing, atmospheric music. Sweet sounds come from passing examples, and gentle gongs signal failing tests. (Note that you won't hear anything unless your test suite run is longer than 5 seconds. Silence is the most pleasing sound of all.)
Fukuzatsu ("complexity") is a tool for measuring code complexity in Ruby class files. Its analysis generates scores based on cyclomatic complexity algorithms, which in simplest terms measure the number of execution paths through a given piece of code. Fukuzatsu was created by Coraline Ada Ehmke with help from Mike Ziwisky. It is intended to be a replacement for popular tools that overstep the ABC algorithm and inject "opinionated" reasoning about code complexity. It was originally inspired by Saikuro, written by Zev Blut.
Snuffle analyzes source code to identify "data clumps", clusters of attributes that are often used together. It uses this analysis to propose objects that may be extracted from a given class. It also looks for objects that are hinted at by method names and identifies them as "latent objects". For example, if you have home_address and work_address methods in a User class, Snuffle will tell you that you might want to extract those methods to a latent Address class. Snuffle is still pre-release and will not be ready for serious use until it hits version 1.0.0. Based on an idea developed with Kerri Miller (@kerrizor).
Alice is a Slack bot with intelligence and personality. Most notable about the Alice project, aside from her natural language processing capabilities and built-in Zork-like game, is her functional-programming-inspired pipeline architecture. You can see see a diagram of this architecture in the project README.
