Method: Parser::Source::Map#to_hash

Defined in:
lib/parser/source/map.rb

#to_hash ⇒ Hash<Symbol, Parser::Source::Range>

Converts this source map to a hash with keys corresponding to ranges. For example, if called on an instance of Collection, which adds the ‘begin` and `end` ranges, the resulting hash will contain keys `:expression`, `:begin` and `:end`.

Examples:

require 'parser/current'

p Parser::CurrentRuby.parse('[1, 2]').loc.to_hash
# => {
#   :begin => #<Source::Range (string) 0...1>,
#   :end => #<Source::Range (string) 5...6>,
#   :expression => #<Source::Range (string) 0...6>
# }
