Open Source Ruby Multimedia Software

Danbooru is a full-featured, open-source web application designed for hosting, organizing, and searching large collections of tagged images, particularly focused on anime-style artwork. Built using Ruby on Rails, it provides a robust tagging system that allows users to categorize images with highly structured metadata, enabling precise and flexible search queries. The platform supports advanced moderation workflows, including user roles, content approval systems, and reporting tools, making it suitable for large-scale community-driven repositories. It also includes features such as image uploads, comment threads, favorites, pools, and wiki pages that provide contextual information about tags and artists. Danbooru is optimized for performance and scalability, capable of handling millions of images while maintaining fast search and retrieval speeds.

This library is used on GitHub.com to detect blob languages, ignore binary or vendored files, suppress generated files in diffs, and generate language breakdown graphs. Linguist is a Ruby library so you will need a recent version of Ruby installed. There are known problems with the macOS/XCode supplied version of Ruby that causes problems installing some of the dependencies. Accordingly, we highly recommend you install a version of Ruby using Homebrew, rbenv, rvm, ruby-build, asdf or other packaging system, before attempting to install Linguist and the dependencies. Linguist uses charlock_holmes for character encoding and rugged for libgit2 bindings for Ruby. These components have their own dependencies. A repository's languages stats can also be assessed from the command line using the github-linguist executable. Without any options, github-linguist will output the breakdown that correlates to what is shown in the language stats bar.

Draper adds an object-oriented layer of presentation logic to your Rails application. Without Draper, this functionality might have been tangled up in procedural helpers or adding bulk to your models. With Draper decorators, you can wrap your models with presentation-related logic to organize and test this layer of your app much more effectively. Imagine your application has an Article model. With Draper, you'd create a corresponding ArticleDecorator. The decorator wraps the model, and deals only with presentational concerns. In the controller, you decorate the article before handing it off to the view. In the view, you can use the decorator in exactly the same way as you would have used the model. But whenever you start needing logic in the view or start thinking about a helper method, you can implement a method on the decorator instead.

sorry is a minimal interactive web app designed to generate playful “sorry” animations, messages or digital apology cards. Users can choose from themed styles (fonts, backgrounds, effects) and enter their own message, and the app renders a stylized apology dynamically. Some versions include animation or transitions—letters fading in, shaking, or dissolving—to make the message more expressive. The interface emphasizes simplicity: a user types the text, previews it live, and can share or export the result. Because it’s lightweight and browser-based, it’s perfect as a novelty site or as an embeddable widget in blogs or chats. Its charm lies in marrying a small amount of interactivity and design flair with a simple, human purpose—apologizing creatively.
