Ruby 3.3 adds a new parser named Prism, uses Lrama as a parser generator, adds a new pure-Ruby JIT compiler named RJIT, and many performance improvements especially YJIT.</p> <h2>Prism</h2> <ul> <li>Introduced <a href="https://web.archive.org/web/20231225071449/https://github.com/ruby/prism">the Prism parser</a> as a default gem <ul> <li>Prism is a portable, error tolerant, and maintainable recursive descent parser for the Ruby language</li> </ul> </li> <li>Prism is production ready and actively maintained, you can use it in place of Ripper <ul> <li>There is <a href="https://web.archive.org/web/20231225071449/https://ruby.github.io/prism/">extensive documentation</a> on how to use Prism</li> <li>Prism is both a C library that will be used internally by CRuby and a Ruby gem that can be used by any tooling which needs to parse Ruby code</li> <li>Notable methods in the Prism API are: <ul> <li><code class="language-plaintext highlighter-rouge">Prism.parse(source)</code> which returns the AST as part of a parse result object</li> <li><code class="language-plaintext highlighter-rouge">Prism.parse_comments(source)</code> which returns the comments</li> <li><code class="language-plaintext highlighter-rouge">Prism.parse_success?(source)</code> which returns true if there are no errors</li> </ul> </li> </ul> </li> <li>You can make pull requests or issues directly on <a href="https://web.archive.org/web/20231225071449/https://github.com/ruby/prism">the Prism repository</a> if you are interested in contributing</li> <li>You can now use <code class="language-plaintext highlighter-rouge">ruby --parser=prism</code> or <code class="language-plaintext highlighter-rouge">RUBYOPT="--parser=prism"</code> to experiment with the Prism compiler. Please note that this flag is for debugging only.</li> </ul> <h2>Use Lrama instead of Bison</h2> <ul> <li>Replace Bison with <a href="https://web.archive.org/web/20231225071449/https://github.com/ruby/lrama">Lrama LALR parser generator</a> <a href="https://web.archive.org/web/20231225071449/https://bugs.ruby-lang.org/issues/19637">[Feature #19637]</a> <ul> <li>If you have interest, please see <a href="https://web.archive.org/web/20231225071449/https://rubykaigi.org/2023/presentations/spikeolaf.html">The future vision of Ruby Parser</a></li> <li>Lrama internal parser is replaced with LR parser generated by Racc for maintainability</li> <li>Parameterizing Rules <code class="language-plaintext highlighter-rouge">(?, *, +)</code> are supported, it will be used in Ruby parse.y</li> </ul> </li> </ul> <h2>YJIT</h2> <ul> <li>Major performance improvements over Ruby 3.2 <ul> <li>Support for splat and rest arguments has been improved.</li> <li>Registers are allocated for stack operations of the virtual machine.</li> <li>More calls with optional arguments are compiled.

The default is set to <code class="language-plaintext highlighter-rouge">0.01</code> (1%).
