Previously the following code did not produce the expected results:
```ruby
bx = binding
block = bx.eval("a = 1; proc { a }")
bx.eval("a = 2")
p block.call # Expect 2 but return 1 due to a bug
```
The previous implementation of `Binding#eval` evaluated the code and then merged the top layer variables.
This patch will parse and expand the variable space before making a call to `eval`.
This means that the call to `Binding#eval` will do the parsing twice.
In addition, the following changes will be made:
- Make `mrb_parser_foreach_top_variable()`, `mrb_binding_extract_proc()` and `mrb_binding_extract_env()` functions private global functions.
- Remove the `posthook` argument from `mrb_exec_irep()`.
The `posthook` argument was introduced to implement the `binding` method.
This patch is unnecessary because it uses a different implementation method.
ref #5362
fixed #5491
mruby-method
An implementation of class Method and UnboundMethod for mruby
p Enumerable.instance_method(:find_all).source_location
#=> ["mruby/mruby/mrblib/enum.rb", 148]
Note
You need to enable debug option in your build configuration to use
source_location method in this gem, for example:
MRuby::Build.new do |conf|
conf.enable_debug
end
