class CodeRay::Encoders::TokenKindFilter
A Filter
that selects tokens based on their token kind.
Options¶ ↑
:exclude¶ ↑
One or many symbols (in an Array) which shall be excluded.
Default: []
:include¶ ↑
One or many symbols (in an array) which shall be included.
Default: :all, which means all tokens are included.
Exclusion wins over inclusion.

Add the token group to the output stream if kind
matches the conditions.
If it does not, all tokens inside the group are excluded from the stream, even if their kinds match.
