v0.9.0

Added

• Regular expressions can now be bound by \n, \r, and a combination of \r\n.
• Strings delimited by %, %q, and %Q can now be bound by \n, \r, and a combination of \r\n.
• IntegerNode#value now returns the value of the integer as a Ruby Integer.
• FloatNode#value now returns the value of the float as a Ruby Float.
• RationalNode#value now returns the value of the rational as a Ruby Rational.
• ImaginaryNode#value now returns the value of the imaginary as a Ruby Complex.
• ClassNode#name is now a string that returns the name of just the class, without the namespace.
• ModuleNode#name is now a string that returns the name of just the module, without the namespace.
• Regular expressions and strings found after a heredoc declaration but before the heredoc body are now parsed correctly.
• The serialization API now supports shared strings, which should help reduce the size of the serialized AST.
• *Node#copy is introduced, which returns a copy of the node with the given overrides.
• Location#copy is introduced, which returns a copy of the location with the given overrides.
• DesugarVisitor is introduced, which provides a simpler AST for use in tools that want to process fewer node types.
• {ClassVariable,Constant,ConstantPath,GlobalVariable,InstanceVariable,LocalVariable}TargetNode are introduced. These nodes represent the target of writes in locations where a value cannot be provided, like a multi write or a rescue reference.
• UntilNode#closing_loc and WhileNode#closing_loc are now provided.
• Location#join is now provided, which joins two locations together.
• YARP::parse_lex and YARP::parse_lex_file are introduced to parse and lex in one result.

Changed

• When there is a magic encoding comment, the encoding of the first token's source string is now properly reencoded.
• Constants followed by unary & are now properly parsed as a call with a passed block argument.
• Escaping multi-byte characters in a string literal will now properly escape the entire character.
• YARP.lex_compat now has more accurate behavior when a byte-order mark is present in the file.
• BREAKING: AndWriteNode, OrWriteNode, and OperatorWriteNode have been split back up into their 0.7.0 versions.
• We now properly support spaces between the encoding and =/: in a magic encoding comment.
• We now properly parse -> foo: bar do end.
