Added scopes for many kernel and special methods in tree-sitter parser #285

Open gsmetal opened 4 years ago

gsmetal commented 4 years ago

Description of the Change

Added scopes for many kernel and special methods in tree-sitter parser. For example:

visibility methods (private, protected ...)
new method
Gemfile-specific methods
lambda notation (->(a) { })
attr_accessors
some predefined constants (ENV, __FILE__)

Alternate Designs

None.

Benefits

More accurate highlighting.

Possible Drawbacks

None.

Applicable Issues

252

Disclaimer

I didn't understand how to "extend" grammars to make Gemfile's grammar separate and just extend ruby grammar with some specials. Is it possible?
I haven't found any explicit information about available scopes and logic for mapping them to each language-specific situation. So I've done my best effort.

As a heads up, except for the gemfile specific methods, #291 provides scopes for everything in this PR.
