The next dev meeting

Date: 2025/10/23 13:00-17:00 (JST)
Log: https://github.com/ruby/dev-meeting-log/blob/master/2025/DevMeeting-2025-10-23.md

• Dev meeting IS NOT a decision-making place. All decisions should be done at the bug tracker.
• Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly.
• Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue).
• We will write a record of the discussion in the file or to each ticket in English.
• All activities are best-effort (keep in mind that most of us are volunteer developers).
• The date, time and place of the meeting are scheduled according to when/where we can reserve Matz's time.
• DO NOT discuss then on this ticket, please.

Call for agenda items

If you have a ticket that you want matz and committers to discuss, please post it into this ticket in the following format:

* [Ticket ref] Ticket title (your name)
  * Comment (A summary of the ticket, why you put this ticket here, what point should be discussed, etc.)

Example:

* [Feature #14609] `Kernel#p` without args shows the receiver (ko1)
  * I feel this feature is very useful and some people say :+1: so let discuss this feature.

• It is recommended to add a comment by 2025/10/20. We hold a preparatory meeting to create an agenda a few days before the dev-meeting.
• The format is strict. We'll use this script to automatically create an markdown-style agenda. We may ignore a comment that does not follow the format.
• Your comment is mandatory. We cannot read all discussion of the ticket in a limited time. We appreciate it if you could write a short summary and update from a previous discussion.

• Related to Misc #14770: [META] DevelopersMeeting added

[kddnewton (Kevin Newton)]

• [Feature #21572] Make illegal variable in alternation pattern a syntax error (kddnewton)
  • Can we make this into a parse-time syntax error as opposed to a compiler error?

[k0kubun (Takashi Kokubun)]

• [Misc #21609] Propose Stan Lo (@st0012 (Stan Lo)) as a core committer (k0kubun)
  • To speed up the ZJIT development, can we let him merge his PRs by himself?

[tenderlovemaking (Aaron Patterson)]

• [Feature #20163] Add Integer#popcount
  • Add a method for counting "on" bits in an integer
  • Raises an exception for negative numbers
  • Method would be helpful for bitsets, bitboards, and other data structures

[Eregon (Benoit Daloze)]

• [Bug #21640] Core Pathname is missing 3 methods / is partially-defined (eregon)
  • This seems a bad user experience: partially-defined class missing some methods, require "pathname" doesn't load the gem as expected (even with Bundler), etc
  • I think it would be better to keep Pathname as a default gem and not core, it avoids all 6 problems.
  • If we absolutely must have Pathname in core, how to fix these 6 problems then?

[matheusrich (Matheus Richard)]

• [Feature #21615] Introduce Array#values
  • Seems reasonable to have an API to simplify traversal of hash/array values
  • There is some precedence, since both Hashes/Arrays have #values_at.
  • If approved, should it be added to Set too?

[jhawthorn (John Hawthorn)]

• [Misc #21646] Propose Luke Gruber as a Ruby committer (jhawthorn)
  • Luke has been fixing bugs in Ractors and elsewhere. Would be helpful if he could merge his own PRs.

[kddnewton (Kevin Newton)]

• [Misc #21630] Suggest @Earlopain for core contributor
  • They have been very helpful for Prism maintenance, and also other areas of Ruby. It would be helpful for them to merge their own PRs.

[kddnewton (Kevin Newton)]

• [Feature #21573] Simpler syntax errors
  • Developers want nice syntax errors in the command line, that is implemented today.
  • Language-agnostic tools that parse stdout want simple-to-parse errors and warnings.
  • Can we add a mode/switch/environment variable/some other mechanism to trigger this?

• Status changed from Open to Closed
