The relative library enhances Ruby's core and standard libraries to support naming, opening, and reading files relative to the Ruby file currently being interpreted (the contents of the __ FILE __ identifier). This functionality is especially useful in embedded Ruby (eruby, erb, erubis, etc.) where absolute paths or paths relative to the interpreter's current working directory are problematic (due to file system structures and working directories varying across platforms and web servers).
rest-open-uri is a hack of, and drop-in replacement for, open-uri. It supports all standard HTTP methods (not just GET) and allows you to send an entity-body. This gem will be deprecated if and when equivalent functionality makes it into core Ruby.
not_pressed-core is the foundational engine behind NotPressed, a fully open-source, batteries-included CMS for Rails 8. It provides hierarchical pages, a block-based content editor, automatic navigation discovery from routes and view partials, a media library backed by Active Storage, a pluggable admin panel with configurable auth, and a content type registry — all built on Hotwire with zero external JS dependencies.
Outputs events to Microsoft Application Insights Analytics open schema tables. This gem is a Logstash output plugin required to be installed on top of the Logstash core pipeline using $LS_HOME/bin/logstash-plugin install gemname. This gem is not a stand-alone program
ontoMDE-core is basically a library for loading a RDFS model in ruby memory and process it to do something usefull such as generating Java or C++ code. ontoMDE-core is used by ontoMDE-uml2 which adds UML2 meta-model definitions and some helper methods. ontoMDE-uml2 is in turn used by ontoMDE-uml2-java which adds methods and rules to generate java5 code. But ontoMDE-core is *not* *UML* *specific* and can be used with *any* RDF[http://en.wikipedia.org/wiki/Resource_Description_Framework] / RDFS[http://en.wikipedia.org/wiki/RDF_Schema] model such as those created with Protege_2000[http://protege.stanford.edu]. This opens to ontoMDE-core users the ability to generate code from custom DSL[http://en.wikipedia.org/wiki/Domain_Specific_Language] models, or join different models. This gem bundles, ontomde-inspector which is a web server for browsing a model and a meta-model inside a running ontomde generator. Inspector is available as an independant script but may also be run from generator (such as ontomde-java with option --inspector or --inspectorAfterLoad ) to provide a view of model before or after generation.
AI4R is a lightweight, educational Ruby library featuring clean implementations of core machine learning and AI algorithms—such as decision trees, neural networks, k-means, genetic algorithms, and even a bit size Transformers architecture covering encoder, decoder, and seq2seq variations. Designed with simplicity and clarity in mind, this library is ideal for students, educators, and developers who want to understand these algorithms line by line. With no external dependencies, no GPU support, and no production overhead, AI4R serves as a practical and transparent way to explore the foundations of AI in Ruby. It is a long-maintained open-source effort to bring accessible, hands-on machine learning to the Ruby community.
OpenClacky is a 100% open-source (MIT) AI Agent that matches Claude Code on capability at comparable cost. Built on two years of agentic R&D, it ships with a minimal 16-tool core, near-100% prompt cache hit rate, idle-time auto-compression, and BYOK support for any OpenAI-compatible model. A natural-language Skill system lets you create, evolve, and monetize agent capabilities without writing code, plus first-class integrations with Feishu, WeCom, WeChat, Discord, and Telegram.
Most is a simple academic modular open software tester. Most, the Core is the main part of the system. Most provides the environment and interface bridges for modules that will implement the basic functionality of the testing system. In general Most, the Core consists form two main interfaces: the connector and the tester. The connector interface offers the basic bridge to make an implementation of a module which will act as a controlling interface of the system. It can be a command line interface or it can be a module which will set up a server providing a network access for end users. The tester interface allows building an implementation of the software validator. By default the Most ships with the tester compliant with the ICPC Validator Standard. The Most system proposes to implement a testing system following this standard, but it is not obligatory. The 3-rd party implementation can vary significantly considering the user preferences. It is possible to build other interface bridges using the abstract interface classes provided by the Most system to extend the functionality of the modules. For example the implementation of the connector interface in the form of the network server can build a tunnel interface bridge, so that developers can make implementations, for example, of a SSH tunnel in order to provide a secure connection with the testing system. The default system bundle is shipped with a number of basic interface implementations (modules). Please, consider taking a look on realize notes for the list of supplied modules.
