[ruby-talk:444796] [ANN] zenweb 3.12.1 Released
by Ryan Davis 14 Apr '26

14 Apr '26

zenweb version 3.12.1 has been released! * home: <https://github.com/seattlerb/zenweb> * bugs: <https://github.com/seattlerb/zenweb/issues> * rdoc: <http://docs.seattlerb.org/zenweb> Zenweb is a set of classes/tools for organizing and formating a website. It is website oriented rather than webpage oriented, unlike most rendering tools. It is content oriented, rather than style oriented, unlike most rendering tools. It uses a rubygems plugin system to provide a very flexible, and powerful system. Zenweb 3 was inspired by jekyll. The filesystem layout is similar to jekyll's layout, but zenweb isn't focused on blogs. It can do any sort of website just fine. Zenweb uses rake to handle dependencies. As a result, scanning a website and regenerating incrementally is not just possible, it is blazingly fast. #### To Install: Changes: ### 3.12.1 / 2026-04-14 * 1 bug fix: * Make Binary pages hard link instead of copy to save some disk.

[ruby-talk:444795] [ANN] minitest 6.0.4 Released
by Ryan Davis 14 Apr '26

14 Apr '26

minitest version 6.0.4 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: ### 6.0.4 / 2026-04-14 * 1 bug fix: * Fixed refute_predicate to call assert_respond_to w/ include_all:true like assert_predicate does. (jparker)

[ruby-talk:444794] [ANN] flay 2.14.4 Released
by Ryan Davis 14 Apr '26

14 Apr '26

flay version 2.14.4 has been released! * home: <http://ruby.sadi.st/> * code: <https://github.com/seattlerb/flay> * rdoc: <http://docs.seattlerb.org/flay/> Flay analyzes code for structural similarities. Differences in literal values, variable, class, method names, whitespace, programming style, braces vs do/end, etc are all ignored. Making this totally rad. ## Features/Problems: * Reports differences at any level of code. * Adds a score multiplier to identical nodes. * Differences in literal values, variable, class, and method names are ignored. * Differences in whitespace, programming style, braces vs do/end, etc are ignored. * Works across files. * Add the flay-persistent plugin to work across large/many projects. * Run --diff to see an N-way diff of the code. * Provides conservative (default) and --liberal pruning options. * Provides --fuzzy duplication detection. * Language independent: Plugin system allows other languages to be flayed. * Ships with .rb and .erb. * javascript and others will be available separately. * Includes FlayTask for Rakefiles. * Uses path_expander, so you can use: * dir_arg -- expand a directory automatically * @file_of_args -- persist arguments in a file * -path_to_subtract -- ignore intersecting subsets of files/directories * Skips files matched via patterns in .flayignore (subset format of .gitignore). * Totally rad. Changes: ### 2.14.4 / 2026-04-14 * 2 bug fixes: * Fix Sexp#[] to return empty sexp if indicies run off the end. (slbug) * Loosened dependency on ruby2ruby to catch up and drop ruby_parser.

[ruby-talk:444791] Regression: Ruby 4.0 constantly crashing
by Peter 'PMc' Much 10 Apr '26

10 Apr '26

Good morning, After upgrade to ruby 4.0, all our Rails applications are continuously crashing on different nodes at different locations. All the applications were running flawlessly for about a year with 4.0.0.p1 and 4.0.0.p2. Reverting to 4.0.0.p2 solves the issue. The behaviour is the same with 4.0.0 and 4.0.1, where 4.0.1 has the additional issue that the value of ulimit "unlimited" has been reduced below "EFBIG", so no coredumps can be written ("too big"). Bug reporting is not possible: After registering an account on https://bugs.ruby-lang.org/, one is requested to follow the instructions in an e-mail, but such e-mail is never sent; not even after repeatedly requesting it. Versions tried: 4.0.0 (2025-12-25 revision 553f1675f3) +PRISM [amd64-freebsd14] 4.0.1 (2026-01-13 revision e04267a14b) +PRISM [amd64-freebsd14] FreeBSD-PR:

[ruby-talk:444789] [ANN] llm.rb 4.11.0 released
by Robert 05 Apr '26

05 Apr '26

Hi all, I’ve been working on a Ruby library called llm.rb and wanted to share today's release (v4.11.0) because it has come a long way. Most LLM libraries focus on requests and responses. In practice, once you build anything non-trivial, you end up dealing with state, tool execution, streaming, and concurrency as first-class concerns. llm.rb is built around that layer. It provides: - Stateful contexts that can be serialized as JSON and restored to a Ruby object. - Explicit tool execution (local, remote, and MCP) - Streaming with structured callbacks and tool-call events - The ability to start tool execution while streaming (overlapping latency) - Explicit concurrency (threads, fibers, async tasks) - Integration with MCP servers over stdio and HTTP - A unified interface across providers (OpenAI, Anthropic, Google, Ollama, etc.) - Runs on Ruby's stdlib by default, opt-in to optional features like async and net-http-persistent The goal is to treat LLMs as part of your system architecture, not just API calls, while keeping everything explicit and stdlib-friendly.

[ruby-talk:444788] [ANN] minitest 6.0.3 Released
by Ryan Davis 01 Apr '26

01 Apr '26

minitest version 6.0.3 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: ### 6.0.3 / 2026-03-31 * 1 bug fix: * assert_same(nil, value) no longer allowed. Use assert_nil to be explicit. (paddor)
