From: "kddnewton (Kevin Newton) via ruby-core" Date: 2024-09-26T15:47:02+00:00 Subject: [ruby-core:119302] [Ruby master Bug#20761] [DOC] `RubyVM::AbstractSyntaxTree.of` examples raise because parser is prism by default Issue #20761 has been updated by kddnewton (Kevin Newton). Status changed from Open to Closed This is expected behavior. The instruction sequences will have different node ids, so it's not possible to retrieve the RubyVM::AbstractSyntaxTree representation of the AST. If you want to retrieve the Prism AST, you can do so using `Prism.parse` in the same way that error highlight does here: https://github.com/ruby/error_highlight/blob/452f78640c08ab277683416668a52d9fcfb6a26a/lib/error_highlight/base.rb#L57-L66. ---------------------------------------- Bug #20761: [DOC] `RubyVM::AbstractSyntaxTree.of` examples raise because parser is prism by default https://bugs.ruby-lang.org/issues/20761#change-109913 * Author: Earlopain (A S) * Status: Closed * 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-c-of ```rb RubyVM::AbstractSyntaxTree.of(proc {1 + 2}) # => :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/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/lists/ruby-core.ml.ruby-lang.org/
