Minimum version requirement for Bison is changed to 3.0. See: https://bugs.ruby-lang.org/issues/19068 [Feature #19068]

* Fix SEGV of dump parsetreeyui-knk2022-10-081-0/+3
| | | | | | | | | Assign internal_id to semantic value so that dump parsetree option can render the tree for these codes without SEGV. * `def m(&); end` * `def m(*); end` * `def m(**); end`
* "expr_value" can be erroryui-knk2022-10-081-0/+6

* Move `error` from top_stmts and top_stmt to stmtyui-knk2022-10-081-8/+6
| | | | | | | | | | | | | | | | | | | By this change, syntax error is recovered smaller units. In the case below, "DEFN :bar" is same level with "CLASS :Foo" now. ``` module Z class Foo foo. end def bar end end ``` [Feature #19013]
* Treat "end" as reserved word with consideration of indentyui-knk2022-10-081-1/+36
| | | | | | | | | | | | | | | | | | | | "end" after "." or "::" is treated as local variable or method, see `EXPR_DOT_bit` for detail. However this "changes" where `bar` method is defined. In the example below it is not module Z but class Foo. ``` module Z class Foo foo. end def bar end end ``` [Feature #19013]

* Add error_tolerant option to RubyVM::ASTyui-knk2022-10-081-1/+14
| | | | | | | If this option is enabled, SyntaxError is not raised and Node is returned even if passed script is broken. [Feature #19013]

* Ignore invalid escapes in regexp commentsJeremy Evans2022-06-061-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Invalid escapes are handled at multiple levels. The first level is in parse.y, so skip invalid unicode escape checks for regexps in parse.y. Make rb_reg_preprocess and unescape_nonascii accept the regexp options. In unescape_nonascii, if the regexp is an extended regexp, when "#" is encountered, ignore all characters until the end of line or end of regexp. Unfortunately, in extended regexps, you can use "#" as a non-comment character inside a character class, so also parse "[" and "]" specially for extended regexps, and only skip comments if "#" is not inside a character class. Handle nested character classes as well. This issue doesn't just affect extended regexps, it also affects "(#?" comments inside all regexps. So for those comments, scan until trailing ")" and ignore content inside. I'm not sure if there are other corner cases not handled. A better fix would be to redesign the regexp parser so that it unescaped during parsing instead of before parsing, so you already know the current parsing state.

* Add support for anonymous rest and keyword rest argument forwardingJeremy Evans2021-12-301-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows for the following syntax: ```ruby def foo(*) bar(*) end def baz(**) quux(**) end ``` This is a natural addition after the introduction of anonymous block forwarding. Anonymous rest and keyword rest arguments were already supported in method parameters, this just allows them to be used as arguments to other methods. The same advantages of anonymous block forwarding apply to rest and keyword rest argument forwarding. This has some minor changes to #parameters output. Now, instead of `[:rest], [:keyrest]`, you get `[:rest, :*], [:keyrest, :**]`. These were already used for `...` forwarding, so I think it makes it more consistent to include them in other cases. If we want to use `[:rest], [:keyrest]` in both cases, that is also possible. I don't think the previous behavior of `[:rest], [:keyrest]` in the non-... case and `[:rest, :*], [:keyrest, :**]` in the ... case makes sense, but if we did want that behavior, we'll have to make more substantial changes, such as using a different ID in the ... forwarding case.

* Assign temporary ID to anonymous ID [Bug #18250]Nobuyoshi Nakada2021-11-231-4/+1
| | | | | | | | Dumped iseq binary can not have unnamed symbols/IDs, and ID 0 is stored instead. As `struct rb_id_table` disallows ID 0, also for the distinction, re-assign a new temporary ID based on the local variable table index when loading from the binary, as well as the parser.
