[ruby-core:111988] [Ruby master Feature#19370] Anonymous parameters for blocks?

Issue #19370 has been reported by zverok (Victor Shepelev). ---------------------------------------- Feature #19370: Anonymous parameters for blocks? https://bugs.ruby-lang.org/issues/19370 * Author: zverok (Victor Shepelev) * Status: Open * Priority: Normal ---------------------------------------- Just to clarify: are anonymous parameters delegation is planned to support in blocks? It would be a nice addition, if it is possible to implement: ```ruby # data in form [request method, URL, params]: [ [:get, 'https://google.com', {q: 'Ruby'}, {'User-Argent': 'Google-Chrome'}], [:post, 'https://gist.github.com', 'body'], # ... ].each { |method, *| request(method.to_s.upcase, *) } ``` ...and at the very least, consistent with what the method definition can have. If they are NOT planned to be implemented, I believe that at least error messages should be made much clearer, because currently, this would happen while running the code above: > no anonymous rest parameter (SyntaxError) I understand the reason (the `request` clause doesn't "see" anonymous parameter of the **block**, and claims that current **method** doesn't have them), but it looks honestly confusing and inconsistent. -- https://bugs.ruby-lang.org/

However, it builds fine with GNU make and when using BSD make with `--with-baseruby`. Previous Ruby tarball releases have built fine with BSD make without `--with-baseruby`, so this issue has been introduced recently. When building with BSD make without `--with-baseruby`, building fails after generating RI format with: ``` /bin/sh: false: not found *** Error 127 in . (exts.mk:94 'ruby': @make UPDATE_LIBRARIES=no EXTENCS=dmyenc.o BASERUBY=echo\ executable\ host\ ruby\ is\ required.\ \ ...) *** Error 2 in /home/jeremy/local/ruby-3.3.0-preview1 (Makefile:948 'build-ext': @make -f exts.mk libdir="/usr/local/lib" LIBRUBY_EXTS=./...) ``` -- https://bugs.ruby-lang.org/

[ruby-core:114722] [Ruby master Bug#19877] Non intuitive behavior of syntax only applied to literal value

Issue #19877 has been reported by tompng (tomoya ishida). ---------------------------------------- Bug #19877: Non intuitive behavior of syntax only applied to literal value https://bugs.ruby-lang.org/issues/19877 * Author: tompng (tomoya ishida) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-09-08T23:08:32Z master b635a66e95) [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Non intuitive behavior of syntax only applied to literal value Some ruby syntax is only applied to literal value. ~~~ruby def 1.foo; end # receiver is a literal, it is Syntax Error /(?<a>)/ =~ s # receiver is regexp literal, it will assign to local variable if cond1..cond2; end # range-like syntax appears in condition, it is flipflop ~~~ If it is wrapped with parenthesis, the behavior seems not intuitive for me, and YARP parses it differently. ~~~ruby def (1).foo; end # Syntax Error def ((1;1)).foo; end # Syntax Error def ((;1)).foo; end # Syntax OK def ((1+1;1)).foo; end # Syntax OK def ((%s();1)).foo; end # Syntax Error def ((%w();1)).foo; end # Syntax OK def ("#{42}").foo; end # Syntax Error def (:"#{42}").foo; end # Syntax OK (/(?<a>)/) =~ s # assigns to a (;/(?<a>)/) =~ s # does not assigns (%s();/(?<a>)/) =~ s # assigns to a (%w();/(?<a>)/) =~ s # does not assigns (1; (2; 3; (4; /(?<a>)/))) =~ s # assigns to a (1+1; /(?<a>)/) =~ s # does not assign if ((cond1..cond2)); end # flipflop if (; cond1..cond2); end # range if (1; cond1..cond2); end # flipflop if (%s(); cond1..cond2); end # flipflop if (%w(); cond1..cond2); end # range if (1; (2; (3; 4; cond1..cond2))); end # flipflop if (1+1; cond1..cond2); end # range ~~~ I expect YARP and parse.y parses same. I expect all parenthesis-wrapped result same. I think it is simple and intuitive if parenthesis-wrapped code always behaves different from non-wrapped code because there are more complex variation like this ~~~ruby def (class A; 1; end).foo; end (break; /?<a>/) =~ s class A; /?<a>/; end =~ s ~~~ -- https://bugs.ruby-lang.org/

[ruby-core:113180] [Ruby master Feature#19588] Allow Comparable#clamp(min, max) to accept nil as a specification

Issue #19588 has been reported by kyanagi (Kouhei Yanagita). ---------------------------------------- Feature #19588: Allow Comparable#clamp(min, max) to accept nil as a specification https://bugs.ruby-lang.org/issues/19588 * Author: kyanagi (Kouhei Yanagita) * Status: Open * Priority: Normal ---------------------------------------- `Comparable#clamp(min, max)` (with two arguments) accepts `nil`. This behaves the same as beginless/endless Range. ~~~ruby 5.clamp(nil, 0) # => 0 5.clamp(10, nil) # => 10 5.clamp(..0) # => 0 5.clamp(10..) # => 10 ~~~ This behavior is not documented. Presumably, this was not introduced intentionally. The old Rubies did not accept accept a `Range` argument. In Ruby 2.7, accepting `Range` as an argument was introduced. At that time, the approach of passing `nil` as a two-argument method was also discussed but not adopted, and using Range was chosen instead. https://bugs.ruby-lang.org/issues/14784 However, in Ruby 3.0, the behavior of `clamp` has changed to accept `nil`. This change is not documented in the NEWS or the documentation for `clamp`, and I believe that it was not an intentional change. ~~~ % docker run -it --rm rubylang/all-ruby env ALL_RUBY_SINCE=ruby-2.4.0 ./all-ruby -e "p 5.clamp(0, nil)" ruby-2.4.0 -e:1:in `clamp': comparison of Integer with nil failed (ArgumentError) from -e:1:in `<main>' exit 1 ... ruby-2.7.8 -e:1:in `clamp': comparison of Integer with nil failed (ArgumentError) from -e:1:in `<main>' exit 1 ruby-3.0.0-preview1 5 ... ruby-3.2.2 5 ~~~ It seems that https://github.com/ruby/ruby/commit/a93da4970be44a473b7b42e7516eb2663dece2c3 brought about this change. How about making the current behavior a specification? It has been three years since the behavior changed, and I don't see much point in prohibiting `nil` now. -- https://bugs.ruby-lang.org/

Issue #19576 has been reported by jprokop (Jarek Prokop). ---------------------------------------- Bug #19576: Backport request: Gemfile.lock resolving is broken with bundler shipped with Ruby 3.1.4 https://bugs.ruby-lang.org/issues/19576 * Author: jprokop (Jarek Prokop) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This is a backport request for bundler, that regressed in 2.3.36 in a specific situation. Newer and older bundler versions that ship with Ruby are not problematic, only the version that ships with Ruby version >= 3.1.3. A few weeks ago, we discovered a bug in resolving in bundler shipped with Ruby 3.1.3 and 3.1.4: Bundler version: ``` $ bundler --version Bundler version 2.3.26 ``` Affected rubies `ruby -v`: First: ``` $ ruby -v ruby 3.1.4p223 (2023-03-30 revision 957bb7cb81) [x86_64-linux] ``` Second: ``` $ruby -v ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-linux] ``` Initial bug report with reproducer and more in-depth description can be found here: https://github.com/sclorg/s2i-ruby-container/issues/469 Using the following Gemfile for a rails app: https://github.com/sclorg/rails-ex/blob/67b7a61eae9efa1088ff3f634ae316e1022… bundler locks up in trying to resolve Nokogiri for Ruby 3.1, but keeps failing because it keeps using incompatible built binary gem instead of falling back to installing and building the binary extension of Nokogiri locally. We craft this Gemfile to be usable from Ruby 2.5 up to Ruby 3.1, as the app is used mainly for testing. I have created a patch to fix the situation, see the attached files. There are 2 of them, one contains the fix and the other one contains the test from the rubygems repo PR#6225. full commit available here: https://src.fedoraproject.org/fork/jackorp/rpms/ruby/c/5ef600a8f40b76de5636… The patches are created from the following upstream changes in bundler: https://github.com/rubygems/rubygems/pull/6225 and adapted: https://github.com/rubygems/rubygems/commit/7b64c64262a7a980c0eb23b96ea56cf… for the PR#6225. With the fix applied I no longer have issues doing `bundle install` with our Gemfile.lock. ---Files-------------------------------- rubygem-bundler-2.3.26-Tests-from-bundler-PR-6225.patch (1.82 KB) rubygem-bundler-2.3.26-Provide-fix-for-bundler-Gemfile-resolving-regression.patch (5.21 KB) -- https://bugs.ruby-lang.org/
