Issue #18368 has been updated by mame (Yusuke Endoh). Status changed from Open to Closed I think there is no task in this ticket. Thank you @zverok ---------------------------------------- Feature #18368: Range#step semantics for non-Numeric ranges https://bugs.ruby-lang.org/issues/18368#change-109954 * Author: zverok (Victor Shepelev) * Status: Closed ---------------------------------------- I am sorry if the question had already been discussed, can't find the relevant topic. "Intuitively", this looks (for me) like a meaningful statement: ```ruby (Time.parse('2021-12-01')..Time.parse('2021-12-24')).step(1.day).to_a # ^^^^^ or just 24*60*60 ``` Unfortunately, it doesn't work with "TypeError (can't iterate from Time)". Initially it looked like a bug for me, but after digging a bit into code/docs, I understood that `Range#step` has an odd semantics of "advance the begin N times with `#succ`, and yield the result", with N being always integer: ```ruby ('a'..'z').step(3).first(5) # => ["a", "d", "g", "j", "m"] ``` The fact that semantic is "odd" is confirmed by the fact that for Float it is redefined to do what I "intuitively" expected: ```ruby (1.0..7.0).step(0.3).first(5) # => [1.0, 1.3, 1.6, 1.9, 2.2] ``` (Like with [`Range#===` some time ago](https://bugs.ruby-lang.org/issues/14575), I believe that to be a strong proof of the wrong generic semantics, if for numbers the semantics needed to be redefined completely.) Another thing to note is that "skip N elements" seem to be rather "generically Enumerable-related" yet it isn't defined on `Enumerable` (because nobody needs this semantics, typically!) Hence, two questions: * Can we redefine generic `Range#step` to new semantics (of using `begin + step` iteratively)? It is hard to imagine the amount of actual usage of the old behavior (with String?.. to what end?) in the wild * If the answer is "no", can we define a new method with new semantics, like, IDK, `Range#over(span)`? **UPD:** More examples of useful behavior (it is NOT only about core `Time` class): ```ruby require 'active_support/all' (1.minute..20.minutes).step(2.minutes).to_a #=> [1 minute, 3 minutes, 5 minutes, 7 minutes, 9 minutes, 11 minutes, 13 minutes, 15 minutes, 17 minutes, 19 minutes] require 'tod' (Tod::TimeOfDay.parse("8am")..Tod::TimeOfDay.parse("10am")).step(30.minutes).to_a #=> [#<Tod::TimeOfDay 08:00:00>, #<Tod::TimeOfDay 08:30:00>, #<Tod::TimeOfDay 09:00:00>, #<Tod::TimeOfDay 09:30:00>, #<Tod::TimeOfDay 10:00:00>] require 'matrix' (Vector[1, 2, 3]..).step(Vector[1, 1, 1]).take(3) #=> [Vector[1, 2, 3], Vector[2, 3, 4], Vector[3, 4, 5]] require 'unitwise' (Unitwise(0, 'km')..Unitwise(1, 'km')).step(Unitwise(100, 'm')).map(&:to_s) #=> ["0 km", "1/10 km", "1/5 km", "3/10 km", "2/5 km", "0.5 km", "3/5 km", "7/10 km", "4/5 km", "9/10 km", "1 km"] ``` **UPD:** Responding to discussion points: **Q:** Matz is concerned that the proposed simple definition will be confusing with the classes where `+` is redefined as concatenation. **A:** I believe that simplicity of semantics and ease of explaining ("it just uses `+` underneath, whatever `+` does, will be performed") will make the confusion minimal. **Q:** Why not introduce new API requirement (like "class of range's `begin` should implement `increment` method, and then it will be used in `step`) **A:** require *every* gem author to change *every* of their objects' behavior. For that, they should be aware of the change, consider it important enough to care, clearly understand the necessary semantics of implementation, have a resource to release a new version... Then all users of all such gems would be required to upgrade. The feature would be DOA (dead-on-arrival). The two alternative ways I am suggesting: change the behavior of `#step` or introduce a new method with desired behavior: 1. Easy to explain and announce 2. Require no other code changes to immediately become useful 3. With something like [backports](https://github.com/marcandre/backports) or [ruby-next](https://github.com/ruby-next/ruby-next) easy to start using even in older Ruby version, making the code more expressive even before it would be possible for some particular app/compny to upgrade to (say) 3.2 All examples of behavior from the code above are real `irb` output with monkey-patched `Range#step`, demonstrating how little change will be needed to code outside of the `Range`. -- https://bugs.ruby-lang.org/

[ruby-core:119322] [Ruby master Feature#6012] Proc#source_location also return the column
by Eregon (Benoit Daloze) 27 Sep '24

27 Sep '24

Issue #6012 has been updated by Eregon (Benoit Daloze). I also really like @ioquatix 's suggestion in https://bugs.ruby-lang.org/issues/6012#note-13 and it is a lot more flexible and more efficient too (since computing e.g. column information if unused is not cheap). For instance `method.source.code` is great because it completely hides the details how to get the source code and slice it. TruffleRuby currently keeps the source code in memory and so could provide this automatically without needing to reread the file from disk. CRuby keeps it but only if `RubyVM.keep_script_lines = true`, so then could use that if available and automatically fallback to read the file from disk (great, because we should avoid users/gems referring to `RubyVM` in their code). One question is where would we place/how would we name this class? We could reuse `Thread::Backtrace::Location` as it's quite similar and already has `path`, `lineno`. But it's not really related to a backtrace here. Still it seems quite a good fit, and I don't have much idea where to place it otherwise (top-level `Source` seems way too prone for conflicts). I think in term of the interface we should have: * start_line * start_column * start_offset * end_line * end_column * end_offset * code: gets the source of the Proc/Method/UnboundMethod ---------------------------------------- Feature #6012: Proc#source_location also return the column https://bugs.ruby-lang.org/issues/6012#change-109936 * Author: rogerdpack (Roger Pack) * Status: Assigned * Assignee: nobu (Nobuyoshi Nakada) ---------------------------------------- As originally suggested in http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/42418 Suggestion/feature request: have #source_location also return the beginning column where it was defined. ["test.rb", 8, 33] Thanks! -roger- -- https://bugs.ruby-lang.org/

Issue #20717 has been reported by mame (Yusuke Endoh). ---------------------------------------- Misc #20717: DevMeeting-2024-10-03 https://bugs.ruby-lang.org/issues/20717 * Author: mame (Yusuke Endoh) * Status: Open ---------------------------------------- # The next dev meeting **Date: 2024/10/03 13:00-17:00** (JST) Log: *TBD* - 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 2024/09/30. 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](https://gist.github.com/mame/b0390509ce1491b43610b9ebb665eb86). 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. -- https://bugs.ruby-lang.org/

[ruby-core:119320] [Ruby master Feature#6012] Proc#source_location also return the column
by Eregon (Benoit Daloze) 27 Sep '24

Issue #6012 has been updated by Eregon (Benoit Daloze). It seems good to revisit this, the workarounds are pretty messy and CRuby-specific, e.g. https://github.com/rails/rails/pull/53055/files I think @mame 's suggestion in https://bugs.ruby-lang.org/issues/6012#note-12 is fine although I think it would be convenient to also expose the byte offsets (start and end): `.source_location #=> [path, start_line, start_column, start_offset, end_line, end_column, end_offset]` Then it would be really easy to "get the source code of a Proc". And of course we should do the same for Method/UnboundMethod (#8751). ---------------------------------------- Feature #6012: Proc#source_location also return the column https://bugs.ruby-lang.org/issues/6012#change-109934 * Author: rogerdpack (Roger Pack) * Status: Assigned * Assignee: nobu (Nobuyoshi Nakada) ---------------------------------------- As originally suggested in http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/42418 Suggestion/feature request: have #source_location also return the beginning column where it was defined. ["test.rb", 8, 33] Thanks! -roger- -- https://bugs.ruby-lang.org/

Issue #20761 has been reported by Earlopain (A S). ---------------------------------------- Bug #20761: [DOC] `RubyVM::AbstractSyntaxTree.of` examples raise because parser is prism by default https://bugs.ruby-lang.org/issues/20761 * Author: Earlopain (A S) * Status: Open * ruby -v: 3.4-dev * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- https://docs.ruby-lang.org/en/master/RubyVM/AbstractSyntaxTree.html#method-… ```rb RubyVM::AbstractSyntaxTree.of(proc {1 + 2}) # => <internal:ast>:97:in 'RubyVM::AbstractSyntaxTree.of': cannot get AST for ISEQ compiled by prism (RuntimeError) ``` Same for the method example. Is this method even functional when prism is used, or is the prism gem able to do this somehow? -- https://bugs.ruby-lang.org/
