2022-06-06Ignore invalid escapes in regexp commentsJeremy Evans
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.

2021-12-30Add support for anonymous rest and keyword rest argument forwardingJeremy Evans
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.

2021-11-23Assign temporary ID to anonymous ID [Bug #18250]Nobuyoshi Nakada
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. Notes: Merged: https://github.com/ruby/ruby/pull/5157
2021-11-21Refactor hacky ID tables to struct rb_ast_id_table_tYusuke Endoh
The implementation of a local variable tables was represented as `ID*`, but it was very hacky: the first element is not an ID but the size of the table, and, the last element is (sometimes) a link to the next local table only when the id tables are a linked list. This change converts the hacky implementation to a normal struct. Notes: Merged: https://github.com/ruby/ruby/pull/5136
