[ruby-talk:444762] [ANN] minitest-debugger 1.1.1 Released
by Ryan Davis 08 Jan '26

08 Jan '26

minitest-debugger version 1.1.1 has been released! * home: <https://github.com/seattlerb/minitest-debugger> * rdoc: <http://docs.seattlerb.org/minitest-debugger> This is a stupid simple example of how easy it is to make a minitest plugin that does something useful. In this case it wraps assert so that failed assertions will drop into the ruby debugger. Changes: ### 1.1.1 / 2026-01-08 * 1 bug fix: * Loosened the minitest dependency to include MT6.

[ruby-talk:444761] [ANN] path_expander 2.0.1 Released
by Ryan Davis 08 Jan '26

08 Jan '26

path_expander version 2.0.1 has been released! * home: <https://github.com/seattlerb/path_expander> * rdoc: <http://docs.seattlerb.org/path_expander> PathExpander helps pre-process command-line arguments expanding directories into their constituent files. It further helps by providing additional mechanisms to make specifying subsets easier with path subtraction and allowing for command-line arguments to be saved in a file. NOTE: this is NOT an options processor. It is a path processor (basically everything else besides options). It does provide a mechanism for pre-filtering cmdline options, but not with the intent of actually processing them in PathExpander. Use OptionParser to deal with options either before or after passing ARGV through PathExpander. Changes: ### 2.0.1 / 2026-01-08 * 4 bug fixes: * Fix path_expander processing of regexp args on windows. * Normalize paths when expanding dirs. * Added CI setup from minitest 6. * Normalize GHA workflow with minitest and others.

flay version 2.14.2 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. Changes: ### 2.14.2 / 2026-01-06 * 1 bug fix: * Namespace NotRubyParser to avoid problems with bundler's horrid eager loading. (nateberkopec)

(nateberkopec) * Patch prism to recognize `it` as a local. (faisal)

[ruby-talk:444758] [ANN] minitest-autotest 1.2.1 Released
by Ryan Davis 07 Jan '26

07 Jan '26

minitest-autotest version 1.2.1 has been released! * home: <https://github.com/seattlerb/minitest-autotest> * rdoc: <http://docs.seattlerb.org/minitest-autotest> autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. minitest-autotest is the latest incarnation of the venerable and wise autotest. This time, it talks to minitest via minitest-server. As a result, there is no output parsing. There are no regexps to tweak. There's no cruft or overhead. Changes: ### 1.2.1 / 2026-01-06 * 3 bug fixes: * Bumped the minitest dependency to MT6. * Dropped path_expander dependency, using vendored version in MT6. * MT6: Needed to load the server plugin via test_prefix.

[ruby-talk:444757] [ANN] xchan.rb v0.20.0 Released
by Robert 06 Jan '26

06 Jan '26

# About xchan.rb is an easy to use, minimalist library for InterProcess Communication (IPC). The library provides a channel that can help facilitate communication between Ruby processes who have a parent <=> child relationship. A channel lock is provided by lockf(3) and a temporary, unlinked file to protect against race conditions that can happen when multiple processes access the same channel at the same time. # Features * Minimalist IPC for parent <=> child processes. * Channel-based communication. * Support for multiple serializers (`:marshal`, `:json`, `:yaml`) * Support for raw string communication (`:pure`). * Blocking (`#send`, `#recv`) operations * Non-blocking (`#send_nonblock`, `#recv_nonblock`) operations. * Built-in file-based locking (lockf(3)) * Option to use a null lock for scenarios where locking is not needed. * Access to underlying UNIX sockets for control over socket options. * Mac, BSD, and Linux support. * Good docs. # Example #!/usr/bin/env ruby require "xchan" ## # Marshal as the serializer ch = xchan(:marshal) Process.wait fork { ch.send(5) } puts "#{ch.recv} + 7 = 12" ch.close ## # 5 + 7 = 12 # Links https://github.com/0x1eef/xchan.rb#readme https://rubygems.org/gems/xchan.rb Best regards, Robert

The higher the score, the more pain the code is in. Changes: ### 4.9.3 / 2026-01-05 * 1 bug fix: * Fixed bug caused by last release duplicating (frozen) options hash. (nateberkopec)

[ruby-talk:444755] [ANN] lockf.rb v3.0.0 Released
by Robert 05 Jan '26

05 Jan '26

# About lockf.rb offers Ruby bindings for the advisory-mode lock provided by the lockf(3) function. It is similar to flock(2) in spirit but it also has semantic differences that can be desirable when used across the fork(2) boundary and that is usually the main reason to use this library. # Example #!/usr/bin/env ruby require "lockf" pids = [] lockf = Lockf.unlinked 5.times do pids << fork { puts "Wait for lock (pid #{Process.pid})" lockf.synchronize do puts "Lock acquired (pid #{Process.pid})" sleep 5 end } end pids.each { Process.wait(it) } ## # Wait for lock (pid 12345) # Lock acquired (pid 12345) # ... # Links https://github.com/0x1eef/lockf.rb https://rubygems.org/gems/lockf.rb Best regards, Robert
