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

2021-10-21`RubyVM.keep_script_lines`Koichi Sasada
`RubyVM.keep_script_lines` enables to keep script lines for each ISeq and AST. This feature is for debugger/REPL support. ```ruby RubyVM.keep_script_lines = true RubyVM::keep_script_lines = true eval("def foo = nil\ndef bar = nil") pp RubyVM::InstructionSequence.of(method(:foo)).script_lines ``` Notes: Merged: https://github.com/ruby/ruby/pull/4913

... 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

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.

As well as `\u`, `\U` should be invalid there too. And highlight including `u`/`U` not only the backslash before it.
2021-05-12Fix handling of control/meta escapes in literal regexpsJeremy Evans
Ruby uses a recursive algorithm for handling control/meta escapes in strings (read_escape). However, the equivalent code for regexps (tokadd_escape) in did not use a recursive algorithm. Due to this, Handling of control/meta escapes in regexp did not have the same behavior as in strings, leading to behavior such as the following returning nil: ```ruby /\c\xFF/ =~ "\c\xFF" ``` Switch the code for handling \c, \C and \M in literal regexps to use the same code as for strings (read_escape), to keep behavior consistent between the two.

2021-01-01Make args info for RubyVM::AST to available on endless method without parensMasataka Pocke Kuwabara
Problem === Arguments information is missing for endless method without parens. For example: ```ruby # ok pp RubyVM::AbstractSyntaxTree.parse(<<~RUBY).children[2] def x() = 42 RUBY # => (DEFN@1:0-1:12 # mid: :x # body: # (SCOPE@1:0-1:12 # tbl: [] # args: # (ARGS@1:5-1:6 # pre_num: 0 # pre_init: nil # opt: nil # first_post: nil # post_num: 0 # post_init: nil # rest: nil # kw: nil # kwrest: nil # block: nil) # body: (LIT@1:10-1:12 42))) # ok pp RubyVM::AbstractSyntaxTree.parse(<<~RUBY).children[2] def x() 42 end RUBY # => (DEFN@1:0-1:14 # mid: :x # body: # (SCOPE@1:0-1:14 # tbl: [] # args: # (ARGS@1:5-1:6 # pre_num: 0 # pre_init: nil # opt: nil # first_post: nil # post_num: 0 # post_init: nil # rest: nil # kw: nil # kwrest: nil # block: nil) # body: (LIT@1:8-1:10 42))) # It has a problem, the `args` is nil pp RubyVM::AbstractSyntaxTree.parse(<<~RUBY).children[2] def x = 42 RUBY # => (DEFN@1:0-1:10 # mid: :x # body: (SCOPE@1:0-1:10 tbl: [] args: nil body: (LIT@1:8-1:10 42))) ``` It causes an error if a program expects `args` node exists. For example: https://github.com/ruby/rbs/issues/551 Solution ==== Call `new_args` on this case. Notes: Merged: https://github.com/ruby/ruby/pull/4016 Merged-By: nobu <nobu@ruby-lang.org>
