Description

Please comment on your favorite ticket numbers you want to ask to discuss with your SHORT comment or summary.
(your summary/comment will help us because we don't need to read all of the ticket comments)

DO NOT discuss then on this ticket, please.


Date: 2019/07/11 (Thu)
Time: 13:00-17:00 (JST)
Place and Sign-up: https://ruby.connpass.com/event/135823/
log: https://docs.google.com/document/d/1K61SGIwp8_rNsPyhmayUcERu71vt_etDjXdhqrLmBVY/edit#

NOTES

  • 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 log about the discussion to a 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 are scheduled according to when/where we can reserve Matz's time.

Discussion


Please comment on your favorite ticket we need to discuss with the following format.

* [Ticket ref] Ticket title (your name)
  * your comment why you want to put this ticket here if you want to add.

Your comment is very important if you are no attendee because we can not ask why you want to discuss it.

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.

We don't guarantee to put tickets in agenda if the comment violate the format (because it is hard to copy&paste).

History

Updated by mame (Yusuke Endoh) 4 months ago

Carry-over tickets.

  • [Feature #14912] Introduce pattern matching syntax (pitr.ch)

    • Could the pattern matching be made available as a first-class citizen to be used as a filter when searching in data structures and to be able to implement Actor receive method
    • Consider contractions log_messages.find in [:error, message] { puts message }
    • Non-symbol matching of Hashes would be very desirable
    • Elaborated in https://bugs.ruby-lang.org/issues/14912#note-22
  • [Feature #15797] Use realpath(3) instead of custom realpath implementation if available (jeremyevans0)

    • Is this OK to commit? It may cause regressions on less common Unix not tested by Travis (e.g. FreeBSD, NetBSD, AIX, Solaris), though we could just fallback to current implementation in that case.
    • Do we want to add workarounds for Mac OS <=10.5 (10.5 was released in October 2007)?

  • [Feature #15903] Move RubyVM.resolve_feature_path to Kernel.resolve_feature_path

    • matz: Could you decide between Kernel.resolve_feature_path and $LOAD_PATH.resolve_feature_path?
  • [Feature #15897] it as a default block parameter and [Misc #15723] Reconsider numbered parameters

    • Could committers continue the discussion from last meeting? Are most people OK with just one implicit argument vs many? I think that could be the first thing to settle.
    • I think a comment from matz sharing his thoughts on either ticket would be helpful.

Updated by nobu (Nobuyoshi Nakada) 4 months ago

  • [Feature #5400] Remove flip-flops in 2.0
    • Strong objections.

Updated by sawa (Tsuyoshi Sawada) 4 months ago

  • [Feature #15950]Allow negative length in Array#[], Array#[]=, Array#slice, Array#slice!, String#[], String#[]=, String#slice, String#slice!
    • 長さの負の値を許し、その場合に左向きに長さを測る提案です。
    • 文字列の右端の定められた長さを取り出すときなどに便利だと思います。
    • これにより、これまで存在していた左端との非対称性を解消できます。
    • これまでnilを返していた一部の場合で文字列を返すようになります。

[Feature #15958] Time#inspect with frac

Updated by Eregon (Benoit Daloze) 4 months ago

  • [Feature #14385] Deprecate back-tick for Ruby 3.
    • What does matz want to use backticks for?
    • It seems too incompatible of a change, isn't it?
  • [Bug #15708] Implicit numbered argument decomposes an array
    • What's the reason of current behavior? Please explain on the ticket.
    • matz: Can you judge whether that behavior is worth the inconsistency with { |x| and making #map, etc not work with unknown element types (if elements can or not be arrays)?

Updated by nobu (Nobuyoshi Nakada) 4 months ago

  • [Feature #11808] Different behavior between Enumerable#grep and Array#grep

    It needs a new C-API.

Updated by Eregon (Benoit Daloze) 4 months ago

  • [Feature #15966] Introducing experimental features behind a flag, disabled by default
    • Could you read the description and reply what you think? Do you think it's a good idea? I think it would be a much better way to introduce experimental features.

  • [Feature #15940] Coerce symbols internal fstrings in UTF8 rather than ASCII to better share memory with string literals

    • Saves some resident memory
    • Makes symbols & constant names defined in UTF-8 files UTF-8 encoded, which is much less surprising.
    • Little to no backward compatibility concerns.
  • [Feature #15939] Dump symbols reference to their fstr in ObjectSpace.dump()

    • It's important for the heap dump consistency. Otherwise when you build the reference graph you end up with some dangling objects.

Updated by nobu (Nobuyoshi Nakada) 3 months ago

  • [Feature #15973] Make Kernel#lambda always return lambda

Updated by nobu (Nobuyoshi Nakada) 3 months ago

  • [Feature #11460] Unhelpful error message when naming a module with the same name as an existing class

Updated by Eregon (Benoit Daloze) 3 months ago

  • [Feature #15987] Let boolean option (such as exception in Kernel#Complex, Kernel#Float, Kernel#Integer, Kernel#Rational) be falsy vs. truthy
    • Does this issue need matz approval or can it be fixed directly? If it does, does matz agree we should address this and use RTEST()?

Updated by mame (Yusuke Endoh) 3 months ago

  • [Feature #15865] <expr> in <pattern> expression (mame)
    • We have some opinions: scoping, matching strictness, the keyword in, and the word order. But all are not specific to the one-line matching. I think it is acceptable if case/in matching is acceptable. May I experimentally commit it as well as case/in?

Updated by jeremyevans0 (Jeremy Evans) 3 months ago

  • [Bug #10463] :~@ and :!@ are not parsed correctly (jeremyevans0)
    • Can we deprecate the automatic conversion of ~@ to ~ and !@ to ! in method names and symbols?

  • [Misc #15805] Let memory sizes of the various IMEMO object types be reflected correctly
  • [Misc #15806] Explicitly initialise encodings on init to remove branches on encoding lookup
    • Currently rb_enc_from_index and related methods explicitly check for encoding table init on each call - I think this should be initialised at boot time instead as even the simple case of loading the interpreter requires the encoding table to be loaded anyways (symbol.c)
