Issue #20761 has been updated by kddnewton (Kevin Newton). Yeah, I think it would make sense to update those docs to indicate that it only works when the instruction sequences were compiled with the old compiler. ---------------------------------------- Bug #20761: [DOC] `RubyVM::AbstractSyntaxTree.of` examples raise because parser is prism by default https://bugs.ruby-lang.org/issues/20761#change-109920 * 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... ```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/
