Ripper

This class provides a compatibility layer between prism and Ripper. It functions by parsing the entire tree first and then walking it and executing each of the Ripper callbacks as it goes. To use this class, you treat ‘Prism::Translation::Ripper` effectively as you would treat the `Ripper` class.

Note that this class will serve the most common use cases, but Ripper’s API is extensive and undocumented. It relies on reporting the state of the parser at any given time. We do our best to replicate that here, but because it is a different architecture it is not possible to perfectly replicate the behavior of Ripper.

The main known difference is that we may omit dispatching some events in some cases. This impacts the following events:

  • on_assign_error

  • on_comma

  • on_ignored_nl

  • on_ignored_sp

  • on_kw

  • on_label_end

  • on_lbrace

  • on_lbracket

  • on_lparen

  • on_nl

  • on_op

  • on_operator_ambiguous

  • on_rbrace

  • on_rbracket

  • on_rparen

  • on_semicolon

  • on_sp

  • on_symbeg

  • on_tstring_beg

  • on_tstring_end
