$ ruby -e 'h = { __ENCODING__ => 1, __ENCODING__ => 2 }'
-e:1: warning: key #<Encoding:UTF-8> is duplicated and overwritten on line 1

It should check the result of `rb_parser_search_nonascii`.
|
|
String nodes holds ruby string object on `VALUE nd_lit`.
This commit changes it to `struct rb_parser_string *string`
to reduce dependency on ruby object.
Sometimes these strings are concatenated with other string
therefore string concatenate functions are needed.
|
|
If the pattern matching is invalid, then the pvtbl would get leaked. For
example:
10.times do
100_000.times do
eval(<<~RUBY)
case {a: 1}
in {"a" => 1}
end
RUBY
rescue SyntaxError
end
puts `ps -o rss= -p #{$$}`

No need to use ENC_CODERANGE to record ascii only or not.
|

Introduce `rb_node_const_decl_val` function to allow `rb_ary_join` and
`rb_ary_reverse` functions to be removed from Universal Parser.

`__ENCODING__ `was managed by `NODE_LIT` with Encoding object.
Introduce `NODE_ENCODING` for
1. `__ENCODING__` is detectable from AST Node.
2. Reduce dependency Ruby object for parse.y
|
|
Before this commit `ruby -y -e 'tap {|;x, y|}'` failed with SEGV.
This change fixes it.
|
|
Instead of scanning before the current comment.

This allows ... argument forwarding to benefit from Allocationless
Anonymous Splat Forwarding, allowing the `f` call below to not
allocate an array or a hash.
```ruby
a = [1]
kw = {b: 2}
def c(a, b:)
end
def f(...)
c(...)
end
f(*a, **kw)
```
This temporarily skips prism locals tests until prism is changed
to use * and ** for ..., instead of using ruby2_keywords.
Ignore failures in rbs bundled gems tests, since they fail due
to this change.

This commit changes `struct parser_params` lastline and nextline
from `VALUE` (String object) to `rb_parser_string_t *` so that
dependency on Ruby Object is reduced.
`parser_string_buffer_t string_buffer` is added to `struct parser_params`
to manage `rb_parser_string_t` pointers of each line. All allocated line
strings are freed in `rb_ruby_parser_free`.
|
|
In `args: args ',' arg_splat`, `args` is not unique name.
Currently the associated rule is interpreted as
`$$ = rest_arg_append(p, $$, $3, &@$);`.
The action works as expected because `$$` is initialized with
`$1` before each action is executed.
However it's misleading then change to use index.
|
|
|
|
Before this commit, Array is used to store token locations
which expect `end` token, e.g. `class` and `module`.
This commit introduces dedicated struct to manage them
so that dependency on Ruby Object is reduced.
|
|
|
|
It's allocated outside of parser then no need to track
reference count in rb_parser_config.
|
|
|
|
|
|
The encodings determined at runtime are affected by the runtime
environment, such as the OS and locale, while the file contents are
not.

The strterm is leaked when there is invalid syntax.
For example:
10.times do
100_000.times do
begin
RubyVM::InstructionSequence.compile('private def foo = puts "Hello"')
rescue SyntaxError
end
end
puts `ps -o rss= -p #{$$}`

`:sym` was managed by `NODE_LIT` with `Symbol` object.
This commit introduces `NODE_SYM` so that
1. Symbol literal is detectable from AST Node
2. Reduce dependency on ruby object
|
|
|
|
|
|
|
|
parse.y converted NODE_STR when the string is hash key like
```
h1 = {"str1" => 1}
m1("str2" => 2)
m2({"str3" => 3})
```
This commit stop the conversion.
`static_literal_node_p` needs to know the node is for hash key or not
for the optimization.
|
|
Change the argument to align with other node value functions
like `rb_node_line_lineno_val`.
|
|
These nodes are not NOTE_LIT, so need to treat separately.
|
|
`set_yylval_node` in ripper does not use the argument at all.
|
|
|
|
|
|
When hash keys are duplicated, e.g. `h = {k: 1, l: 2, k: 3}`,
parser changes node structure for correct compilation.
This generates tricky AST. This commit removes AST manipulation
from parser to keep AST structure simple.

`__FILE__` was managed by `NODE_STR` with `String` object.
This commit introduces `NODE_FILE` and `struct rb_parser_string` so that
1. `__FILE__` is detectable from AST Node
2. Reduce dependency ruby object
|
|
Print warning for a code like
```ruby
if __LINE__
end
# => warning: literal in condition
```
|
|
`__LINE__` was managed by `NODE_LIT` with `Integer` object.
This commit introduces `NODE_LINE` so that
1. `__LINE__` is detectable from AST Node
2. Reduce dependency ruby object
