[ruby-talk:444024] [ANN] ruby_parser 3.19.2 Released
by Ryan Davis 03 Dec '22

03 Dec '22

ruby_parser version 3.19.2 has been released! * home: <https://github.com/seattlerb/ruby_parser> * bugs: <https://github.com/seattlerb/ruby_parser/issues> * rdoc: <http://docs.seattlerb.org/ruby_parser> ruby_parser (RP) is a ruby parser written in pure ruby (utilizing racc--which does by default use a C extension). It outputs s-expressions which can be manipulated and converted back to ruby via the ruby2ruby gem. As an example: def conditional1 arg1 return 1 if arg1 == 0 return 0 end becomes: s(:defn, :conditional1, s(:args, :arg1), s(:if, s(:call, s(:lvar, :arg1), :==, s(:lit, 0)), s(:return, s(:lit, 1)), nil), s(:return, s(:lit, 0))) Tested against 801,039 files from the latest of all rubygems (as of 2013-05): * 1.8 parser is at 99.9739% accuracy, 3.651 sigma * 1.9 parser is at 99.9940% accuracy, 4.013 sigma * 2.0 parser is at 99.9939% accuracy, 4.008 sigma * 2.6 parser is at 99.9972% accuracy, 4.191 sigma * 3.0 parser has a 100% parse rate. * Tested against 2,672,412 unique ruby files across 167k gems. * As do all the others now, basically. Changes: ### 3.19.2 / 2022-12-03 * 5 bug fixes: * Fixed bug parsing array patterns using %w, %i, etc. * Fixed dedenting when heredoc has only empty line and interpolation. (mvz) * Fixed dsym unescaping. (mvz) * Fixed vars in pattern matching that should be lasgn, not lvar. * find_pat mid-patterns are now splatted inline, not wrapped in an array_pat.

It isn't possible to implement i++, but it is... kinda... possible to implement ++i. Take a look at the following code. Just please don't use it in production 😉 class IntContainer def initialize(value, origref=nil) @value = value @origref = origref end def +@ case @origref when nil IntContainer.new(+@value, self) else @origref.value += 1 @origref end end def -@ case @origref when nil IntContainer.new(-@value, self) else @origref.value -= 1 @origref end end attr_accessor :value def method_missing(meth, ...) IntContainer.new((a)value.send(meth, ...)) end def inspect(...) = @value.inspect(...) def to_s(...) = @value.to_s(...) end int = IntContainer.new(5) p int + 10 ++int p int --int p int On 10/14/22 19:01, iloveruby wrote: > Is it posible define new method :++ to Integer class? > > Thanks! > > > Enviado desde Proton Mail móvil > > > > -------- Mensaje original -------- > El 14 oct 2022 4:53, Martin DeMello < martindemello(a)gmail.com> escribió: > > > i++ works in C and similar languages because a variable is a > concrete object, representing a specific chunk of memory. i++ > increments the contents of that chunk of memory. > > in ruby, a variable is a transparent reference to an object, so > any operation on a variable is actually an operation on the object > it points to. i++ would mean "mutate the object i points to by > incrementing it by 1", and since numbers are immutable you cannot > do that. on the other hand, "i += 1" is just shorthand for "i = > i + 1", which means "point the variable i to a new object that is > 1 more than the object it currently points to", which works fine > with ruby's semantics. > > here's an illustration by contrast with strings, which do have > mutating methods: > > > irb(main):001:0> a = "hello" > => "hello" > irb(main):002:0> b = a > => "hello" > irb(main):003:0> a.upcase! > => "HELLO" > irb(main):004:0> b > => "HELLO" > irb(main):005:0> i = 1 > => 1 > irb(main):006:0> j = i > => 1 > irb(main):007:0* i++ # <- what would you expect j to be after this? > > > martin > > On Thu, Oct 13, 2022 at 7:40 PM Henrik P <henrik(a)simplemail.co.in> > wrote: > > I found for a int the "++" operator doesn't work in ruby. > such as, > > i=0 > i++ > > not working. but instead it would write as: > > i=0 > i += 1 > > so "++" is not supported in ruby really? thanks > > > $ ruby -v > ruby 2.6.3p62 (2019-04-16 revision 67580) > [universal.x86_64-darwin20] > > -- > Simple Mail > https://simplemail.co.in/ > > Unsubscribe: > <mailto:ruby-talk-request@ruby-lang.org?subject=unsubscribe> > <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-talk> > > > Unsubscribe: <mailto:ruby-talk-request@ruby-lang.org?subject=unsubscribe> > <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-talk>

[ruby-talk:444016] [ANN] Opal 1.6.0 and Opal-RSpec 1.0.0 released
by hmdne 29 Nov '22

29 Nov '22

Opal 1.6.0 and Opal-RSpec 1.0.0 have been released! * home: https://opalrb.com/ * github: https://github.com/opal/opal * chat: https://slack.opalrb.com/ Opal is a Ruby (3.1) to JavaScript (ES5) compiler allowing you to write frontend code in pure Ruby and have it translated to clean and efficient JavaScript. It also includes a highly compatible core library that includes all the methods you've come to love. All this with a robust support of source maps, so you can debug Ruby code, not JavaScript in your Web Console. It can be used both to create websites entirely in Ruby (using Opal-Browser <https://github.com/opal/opal-browser>, or ports of known JavaScript libraries <https://opalrb.com/libraries/>) and to port existing Ruby libraries to JavaScript, to be ran both in Node.JS and in web browsers (and other JavaScript environments). Opal-RSpec is an Opal port of RSpec <https://rspec.info/>, a well known Ruby testing tool, allowing you to easily test your Ruby applications in browser and in Node, just like you can do so with MRI. This release of Opal is focused primarily on improving upon MRI compatibility. We now fully support freezing and also we now have a new robust and hackable control flow instruction handling implementation (think: `break`, `next`, `return`...). Also, Windows support has been improved and Opal gained a parallel compile support - significantly improving compile times on multicore systems. In addition, the `await` subsystem is no longer experimental. Try it now on <https://opalrb.com/try>, or get started instantly with no further steps required (except for installing Ruby): gem install opal # Try either of the following examples: opal -e 'puts "Hello world!"' opal -ce 'puts "Hello world!"' > hello_world.js node hello_world.js opal -OcEe 'puts "Hello world!"' # Or run it in a web browser: bundle init bundle add opal-browser puma bundle add rack -v '< 3' bundle exec opal -Rserver -qopal-browser -rbrowser -e '$document.write("Hello world!")' Read more release notes on: https://opalrb.com/blog/2022/11/24/opal-1-6-opal-rspec-1-0/ Full changelog: Changed * No longer truncate stacktraces to 15 lines (#2440 <https://github.com/opal/opal/pull/2440>) * Mark async/await as non-experimental (#2477 <https://github.com/opal/opal/pull/2477>) Performance * Improve method block performance for runtime (#2449 <https://github.com/opal/opal/pull/2449>) * Uninline non-typical argument handling (#2419 <https://github.com/opal/opal/pull/2419>) * Logic optimization of runtime.js (#2415 <https://github.com/opal/opal/pull/2415>) * Windows support for |performance:compare| CI check (#2450 <https://github.com/opal/opal/pull/2450>) * Improve block performance for even more cases (#2465 <https://github.com/opal/opal/pull/2465>) Added * Added support for |#freeze| and |#frozen?| (#2444, #2468) * Add CLI support for ESM, at least for Chrome, NodeJS, QuickJS and GJS (#2435 <https://github.com/opal/opal/pull/2435>) * Support exit in Chrome CLI Runner, both sync and async (#2439 <https://github.com/opal/opal/pull/2439>) * Make sure the Server CLI Runner can pick up changes in sources (#2436 <https://github.com/opal/opal/pull/2436>) * Delegate and ruby2_keywords (#2446 <https://github.com/opal/opal/pull/2446>) * Source code can now be embedded in the compiled file to improve development/debugging, e.g. RSpec reports, |Proc#source_location| (#2440 <https://github.com/opal/opal/pull/2440>) * Added |Kernel#caller_locations| (#2440 <https://github.com/opal/opal/pull/2440>) * |Opal::Builder::Prefork| for blazingly fast multicore compilation times (#2263, #2462, #2454, #2469, #2475) * Add |Opal::BuilderProcessors::RubyERBProcessor| (#2470 <https://github.com/opal/opal/pull/2470>) Fixed * Closure tracking support fixes a whole array of bugs handling |break| / |next| / |retry| / … (#2357 <https://github.com/opal/opal/pull/2357>) * Fix an edge case of if in the most complex form not returning (#2433 <https://github.com/opal/opal/pull/2433>) * |String#length| is now available when using |opal/mini| (#2438 <https://github.com/opal/opal/pull/2438>) * Auto-await produced invalid code (#2440 <https://github.com/opal/opal/pull/2440>) * Fix |Enumerable#collect_concat| and |#flat_map| implementation (#2440 <https://github.com/opal/opal/pull/2440>) * Improved await support for PromiseV1 (#2440 <https://github.com/opal/opal/pull/2440>) * Compilation error occurs while compiling |being/end| returning a |case/when| (#2459 <https://github.com/opal/opal/pull/2459>) * Ensure UTF-8 encoding of |.sourcesContent| of source maps (#2451 <https://github.com/opal/opal/pull/2451>) * Benchmarks require string/unpack (#2453 <https://github.com/opal/opal/pull/2453>) * Fix compilation of a call: |gets&.chomp| (#2473 <https://github.com/opal/opal/pull/2473>) * Fix specs on Windows (#2460 <https://github.com/opal/opal/pull/2460>) * Make opal CLI tool work again with pipes (#2474 <https://github.com/opal/opal/pull/2474>) Internal * GitHub Workflows security hardening (#2432 <https://github.com/opal/opal/pull/2432>) * Retry if file cache write operation exits with Zlib::BufError (#2463 <https://github.com/opal/opal/pull/2463>) * Eliminate redundant |var constructor| in |allocate_class| (#2452 <https://github.com/opal/opal/pull/2452>) * Fix |performance:compare| asset size calculation (#2457 <https://github.com/opal/opal/pull/2457>) * Fix a few specs after the Opal RSpec 1.0 (alpha) release (#2471, #2472)
