Hello mruby-llm is generally available: https://github.com/llmrb/mruby-llm. It supports chat, sessions with serialization, MCP, tools, streaming, and much more. It is a fork of llm.rb that has been adapted for mruby, and supports nearly all the same features - which is a lot. Robert

[ruby-talk:444816] [ANN] db-gui 0.4.0 Released
by Andy Maleh 04 May '26

DB GUI is a Database querying desktop app built in Ruby. It supports PostgreSQL to start. Version 0.4.0 added support for remembering SQL command history. I needed that feature at my job, so I added it very quickly, thanks to the awesomeness of Ruby!

[ruby-talk:444815] [ANN] llm.rb adds Kernel.fork support
by Robert 04 May '26

04 May '26

Hello At the moment llm.rb lets you spawn a tool with a number of different concurrency strategies: fiber, thread, async-task, and ractor. The first three are great for IO bound work, ractor is great for CPU bound work but is not always easy to use. Enter Kernel.fork The fifth strategy is Kernel.fork backed by an IPC layer that transports values between a parent and child. It is also usually easier to use than ractors - at least for now. With this change llm.rb makes it easy to execute your tools with all the major concurrency strategies that Ruby supports, so you can focus on solving problems and not implementing infrastructure that is usually not easy to get right. Check it out: https://github.com/llmrb/llm.rb#readme Robert

[ruby-talk:444814] [ANN] relay.app v0.1.0 released
by Robert 04 May '26

04 May '26

Hi Yesterday I launched relay.app Relay is a self-hostable LLM environment with support for OpenAI, DeepSeek, Anthropic, xAI and zAI out of the box. It has a minimal set of dependencies - built on Roda, Sequel, Falcon, llm.rb, HTMX and web sockets. It is intentionally simple to get started, you should be up and running in under two minutes gem install relay.app relay setup relay start Check screenshots and more at https://github.com/llmrb/relay.app#readme If you want an LLM you can extend, it's worth a look. You can drop your own tools into ~/.relay/tools and have the LLM discover them automatically. No LLM experience required. Robert

[ruby-talk:444813] [ANN] minitest 6.0.6 Released
by Ryan Davis 01 May '26

01 May '26

minitest version 6.0.6 has been released! * home: <https://minite.st/> * code: <https://github.com/minitest/minitest> * bugs: <https://github.com/minitest/minitest/issues> * rdoc: <https://docs.seattlerb.org/minitest> * clog: <https://github.com/minitest/minitest/blob/master/History.rdoc> minitest provides a complete suite of testing facilities supporting TDD, BDD, and benchmarking. "I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is *very* readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/test is a small and incredibly fast unit testing framework. It provides a rich set of assertions to make your tests clean and readable. minitest/spec is a functionally complete spec engine. It hooks onto minitest/test and seamlessly bridges test assertions over to spec expectations. minitest/benchmark is an awesome way to assert the performance of your algorithms in a repeatable manner. Now you can assert that your newb co-worker doesn't replace your linear algorithm with an exponential one! minitest/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/test is meant to have a clean implementation for language implementors that need a minimal set of methods to bootstrap a working test suite. For example, there is no magic involved for test-case discovery. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply. ## Features/Problems: * minitest/autorun - the easy and explicit way to run all your tests. * minitest/test - a very fast, simple, and clean test system. * minitest/spec - a very fast, simple, and clean spec system. * minitest/benchmark - an awesome way to assert your algorithm's performance. * minitest/pride - show your pride in testing! * minitest/test_task - a full-featured and clean rake task generator. * Incredibly small and fast runner, but no bells and whistles. * Written by squishy human beings. Software can never be perfect. We will all eventually die. Changes: ### 6.0.6 / 2026-04-30 * 2 bug fixes: * Fix using assert_equal/same/nil w/ BasicObject by comparing w/ `nil == exp`. (mtasaka) * Removed private Assertions#_where as it is no longer used.

[ruby-talk:444810] What took 1.5 months to build in React JS code took 1.5 days in Glimmer DSL for Web Ruby code
by Andy Maleh 28 Apr '26

28 Apr '26

What took 1.5 months to build in React JS code took 1.5 days in Glimmer DSL for Web Ruby code When I reimplemented a React component as the first Glimmer DSL for Web Component in my job's Fintech Rails web app, I thought I did what would have taken 1 week in React in 1.5 days in Glimmer, which seemed like a great improvement in productivity at the time (333.33% the productivity if we count 1 week of React as 5 business days). I recently inspected the Git timeline of the original React component, and discovered that it actually took 1.5 months to develop initially!!!

[ruby-talk:444809] [ANN] llm.rb v5.1.0 Released
by Robert 25 Apr '26

25 Apr '26

Hello llm.rb is the most capable runtime for building AI systems in Ruby. It is built on the standard library (zero dependencies) but it can still support advanced features through optional dependencies that are loaded on-demand. For example, it can integrate with both ActiveRecord and Sequel, and supports persistent connection pools with net-http-persistent. Since my last email, skill support has been added. It behaves in a similar way to Claude or Codex skills, and launches a sub-agent to execute a skill - with a limited tool subset.

[ruby-talk:444808] wroclove.rb 2026 workshop exercises - Building Rails SPAs in Frontend Ruby w/ Glimmer DSL for Web
by Andy Maleh 25 Apr '26

25 Apr '26

I published a GitHub repo containing the exercises of the wroclove.rb 2026 Ruby conference workshop "Building Rails SPAs in Frontend Ruby with Glimmer DSL for Web". This GitHub repo provides the simplest and fastest way to learn Glimmer DSL for Web (the Ruby-in-the-Browser Rails Frontend Framework that won a Fukuoka Prefecture Future IT Initiative 2025 award after getting judged by Matz and other Fukuoka judges). And, just in time for wroclove.rb 2026, Glimmer DSL for Web now has official Rails 8 setup instructions. https://andymaleh.blogspot.com/2026/04/exercises-for-wrocloverb-2026-ruby.h…

hoe version 4.7.0 has been released! * home: <https://zenspider.com/projects/hoe.html> * code: <https://github.com/seattlerb/hoe> * bugs: <https://github.com/seattlerb/hoe/issues> * doco: <https://docs.seattlerb.org/hoe/> * clog: <https://github.com/seattlerb/hoe/blob/master/History.rdoc> Hoe is a rake/rubygems helper for project Rakefiles. It helps you manage, maintain, and release your project and includes a dynamic plug-in system allowing for easy extensibility. Hoe ships with plug-ins for all your usual project tasks including rdoc generation, testing, packaging, deployment, and announcement. See class rdoc for help. Hint: `ri Hoe` or any of the plugins listed below. For extra goodness, see: https://docs.seattlerb.org/hoe/Hoe.pdf ## Features/Problems: * Includes a dynamic plug-in system allowing for easy extensibility. * Auto-intuits changes, description, summary, and version. * Uses a manifest for safe and secure deployment. * Provides 'sow' for quick project directory creation. * Sow uses a simple ERB templating system allowing you to capture your project patterns. Changes: ### 4.7.0 / 2026-04-22 * 2 minor enhancements: * Added cov_branches to enable branch level coverage reporting. * Merged hoe/gemcutter into hoe/package. Distinction doesn't make sense.
