[Bug #21049]
|
|
This commit allows codes like `a b do end.()` and `a b do end&.()`.
|
|
`ruby2_keywords` is set only to be `0` in parse.y.
However `args->ruby2_keywords` is initialized with `0` by `MEMZERO`
in `rb_node_args_new` function and `body->param.flags.ruby2_keywords`
is initialized with `0` by `ZALLOC` in `rb_iseq_constant_body_alloc` function,
so `args->ruby2_keywords` does nothing for `body->param.flags.ruby2_keywords`.
|
|
Because `FORWARD_ARGS_WITH_RUBY2_KEYWORDS` definition was removed
by 4f77d8d3289ece0e3537d9273a5c745120bff59a.
|
|
In the past parse.y and ripper had different `new_nil` definition
so that `new_nil` returns `nil` for ripper.
```c
// parse.y
#define new_nil(loc) NEW_NIL(loc)
// ripper
#define new_nil(loc) Qnil
```
However Rearchitect Ripper (89cfc1520717257073012ec07105c551e4b8af7c)
removed `new_nil` definition for ripper then this commit removes
needless parse.y macro and uses `NEW_NIL` directly.
|
|
In the past parse.y and ripper had different `value_expr` definition
so that `value_expr` does nothing for ripper.
```c
// parse.y
#define value_expr(node) value_expr_gen(p, (node))
// ripper
#define value_expr(node) ((void)(node))
```
However Rearchitect Ripper (89cfc1520717257073012ec07105c551e4b8af7c)
removed `value_expr` definition for ripper then this commit removes
needless parse.y macro and uses `value_expr_gen` directly.
|
|
This commit makes these codes to be invalid.
```ruby
case 0
in [a] | 1
end
case 0
in { a: b } | 1
end
case 0
in [{ a: [{ b: [{ c: }] }] }] | 1
end
```
|
|
Should fail even with `-c` option.
|
|
`brace_block` is `'{' brace_body '}'` or `k_do do_body k_end`.
Both of them are not null so no need to check `$5`.
|
|
Since `mlhs` is already defined as a nonterminal as follows, using the same name as a parameterizing rule is a bit confusing, so rename the parameterizing rule.

Add locations to struct `RNode_SCLASS`.
memo:
```
@ ProgramNode (location: (1,0)-(1,18))
+-- locals: []
+-- statements:
@ StatementsNode (location: (1,0)-(1,18))
+-- body: (length: 1)
+-- @ SingletonClassNode (location: (1,0)-(1,18))
+-- locals: []
+-- class_keyword_loc: (1,0)-(1,5) = "class"
+-- operator_loc: (1,6)-(1,8) = "<<"
+-- expression:
| @ SelfNode (location: (1,9)-(1,13))
+-- body: nil
+-- end_keyword_loc: (1,15)-(1,18) = "end"
```
|
|
This change makes `RubyVM::AST.of` and `.node_id_for_backtrace_location`
return a parent node of NODE_SCOPE (such as NODE_DEFN) instead of the
NODE_SCOPE node itself.
(In future, we may remove NODE_SCOPE, which is a bit hacky AST node.)
This is preparation for [Feature #21543].
|
|
Add locations to struct `RNode_IN`.
memo:
```bash
> ruby -e 'case 1; in 2 then 3; end' --parser=prism --dump=parsetree
@ ProgramNode (location: (1,0)-(1,24))
+-- locals: []
+-- statements:
@ StatementsNode (location: (1,0)-(1,24))

+-- end_keyword_loc: (1,21)-(1,24) = "end"
```

Add `keyword_module` amd `keyword_end` locations to struct `RNode_MODULE`.
memo:
```
>ruby --dump=parsetree -e 'module A end'
@ ProgramNode (location: (1,0)-(1,12))
+-- locals: []
+-- statements:
@ StatementsNode (location: (1,0)-(1,12))
+-- body: (length: 1)
+-- @ ModuleNode (location: (1,0)-(1,12))
+-- locals: []
+-- module_keyword_loc: (1,0)-(1,6) = "module"
+-- constant_path:
| @ ConstantReadNode (location: (1,7)-(1,8))
| +-- name: :A
+-- body: nil
+-- end_keyword_loc: (1,9)-(1,12) = "end"
+-- name: :A
```

Add keyword_defined locations to struct RNode_DEFINED
|
|
Follow up [Bug #21029].
Currently, `defined? (x;)` returns `expression` when using Prism parser.
See:
- https://github.com/ruby/ruby/pull/12949
- https://bugs.ruby-lang.org/issues/21029
However, `defined? (x;)` returns nil when using parse.y, as reported in bug ticket comment and test-all (when using parse.y parser) test result.
This change adds a context flag to track trailing semicolons in defined? scope.
When a trailing semicolon is detected within a defined? scope, the generated AST node is wrapped with NODE_BLOCK.
This change ensures consistent behavior with `defined? (;x)` .

It was defined in `arg` only; moved that pattern to `op_asgn` rule to
share it with `command_asgn`.

NODE_LINE and NODE_ENCODING cases are used SWITCH_BY_COND_TYPE macro that is same to NODE_INTEGER and other cases.
NODE_LINE and NODE_ENCODING cases can be marge to NODE_INTEGER and other node cases.
