* Fix use of numbered parameter inside proc that is default value of optargJeremy Evans2019-05-051-0/+1
| | | | | | | | | | | | | | | | This allows cases such as: ```ruby m ->(a = ->{@1}) {a} m.call.call(1) m2 ->(a: ->{@1}) {a} m2.call.call(2) ``` Previously, this would cause a syntax error. [Bug#15789]
* Fix a case where numbered parameters should not be allowedJeremy Evans2019-05-051-0/+1
| | | | | | | | | | | | | | | | | | Because `proc{|| @1}` is a syntax error, the following should also be syntax errors: ```ruby proc { | | @1} ``` ```ruby proc { |; a| @1 } ``` This fixes both cases. [Bug #15825]
* parse.y: duplicated when clause warningNobuyoshi Nakada2019-05-051-7/+87
| | | | | * parse.y (case_args): moved "duplicated when clause" warning from compile phase, so that `ruby -wc` shows them.

* Disallow also CR in here-doc identifierNobuyoshi Nakada2019-04-291-1/+1
| | | | | | * parse.y (heredoc_identifier): CR in here-document identifier might or might not result in a syntax error, by the EOL code. make a syntax error regardless of the EOL code.
* parse.y: fix here-doc identifier with newlineNobuyoshi Nakada2019-04-291-12/+2
| | | | | | | | | | | | | | | * parse.y (heredoc_identifier): quoted here-document identifier must end within the same line. the only corner case that here-document identifier can contain a newline is that the closing qoute is placed at the beginning of the next line, and has been warned since 2.4. ```ruby <<"EOS " # warning: here document identifier ends with a newline EOS ```
* Hide internal IDsNobuyoshi Nakada2019-04-261-1/+2
| | | | | | | | * parse.y (internal_id): number the ID serial for internal use by counting down from the neary maximum value, not to accidentally match permanent IDs. [Bug #15768]
