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.

2021-12-13Remove `NODE_DASGN_CURR` [Feature #18406]Nobuyoshi Nakada
This `NODE` type was used in pre-YARV implementation, to improve the performance of assignment to dynamic local variable defined at the innermost scope. It has no longer any actual difference with `NODE_DASGN`, except for the node dump. Notes: Merged: https://github.com/ruby/ruby/pull/5251

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

`RubyVM.keep_script_lines` enables to keep script lines for each ISeq and AST.

... as per ko1's preference. He is preparing to extend this feature to ISeq for his new debugger. He prefers "keep" to "save" for this wording. This API is internal and not included in any released version, so I change it in advance.

2021-07-21Fix interpolated heredoceileencodes
This fixes https://bugs.ruby-lang.org/issues/18038. The provided reproduction showed that this happens in heredocs with double interpolation. In this case `DSTR` was getting returned but needs to be convered to a `EVSTR` which is what is returned by the function. There may be an additional bug here that we weren't able to produce. It seems odd that `STR` returns `DSTR` while everything else should return `EVSTR` since the function is `new_evstr`.

2021-07-17One-line pattern matching is no longer experimentalKazuki Tsujimoto
https://github.com/ruby/dev-meeting-log/blob/master/DevelopersMeeting20210715Japan.md#feature-17724-make-the-pin-operator-support-instanceclassglobal-variables-jeremyevans0
2021-07-15Add pattern matching pin support for instance/class/global variablesJeremy Evans
Pin matching for local variables and constants is already supported, and it is fairly simple to add support for these variable types. Note that pin matching for method calls is still not supported without wrapping in parentheses (pin expressions). I think that's for the best as method calls are far more complex (arguments/blocks).

2021-06-18node.h: Reduce struct size to fit with Ruby object size (five VALUEs)Yusuke Endoh
by merging `rb_ast_body_t#line_count` and `#script_lines`. Fortunately `line_count == RARRAY_LEN(script_lines)` was always satisfied. When script_lines is saved, it has an array of lines, and when not saved, it has a Fixnum that represents the old line_count. Notes: Merged: https://github.com/ruby/ruby/pull/4581
2021-06-18ast.rb: RubyVM::AST.parse and .of accepts `save_script_lines: true`Yusuke Endoh
This option makes the parser keep the original source as an array of the original code lines. This feature exploits the mechanism of `SCRIPT_LINES__` but records only the specified code that is passed to RubyVM::AST.of or .parse, instead of recording all parsed program texts.
