Overview

This is a result specific to the parse and parse_file methods.

Class Method Summary

Result - Inherited

.new

Create a new result object with the given values.

Instance Attribute Summary

  • #value readonly

    The syntax tree that was parsed from the source code.

Result - Inherited

#comments

The list of comments that were encountered during parsing.
#data_loc

An optional location that represents the location of the __END__ marker and the rest of the content of the file.
#errors

The list of errors that were generated during parsing.
#failure?

Returns true if there were errors during parsing and false if there were not.
#magic_comments

The list of magic comments that were encountered during parsing.
#source

A Source instance that represents the source code that was parsed.
#success?

Returns true if there were no errors during parsing and false if there were.
#warnings

The list of warnings that were generated during parsing.

Instance Method Summary

  • #attach_comments!

    Attach the list of comments to their respective locations in the tree.

  • #deconstruct_keys(keys)

    Implement the hash pattern matching interface for ParseResult.

  • #errors_format

    Returns a string representation of the syntax tree with the errors displayed inline.

  • #mark_newlines!

    Walk the tree and mark nodes that are on a new line, loosely emulating the behavior of CRuby’s :line tracepoint event.

Result - Inherited

#code_units_cache

Create a code units cache for the given encoding.
#deconstruct_keys

Implement the hash pattern matching interface for Result.
#encoding

Returns the encoding of the source code that was parsed.
