CodeRay::Encoders::LinesOfCode

Counts the LoC (Lines of Code). Returns an Integer >= 0.

Alias: :loc

Everything that is not comment, markup, doctype/shebang, or an empty line, is considered to be code.

For example,

A Scanner class should define the token kinds that are not code in the KINDS_NOT_LOC constant, which defaults to [:comment, :doctype].

Constants

NON_EMPTY_LINE
