class CodeRay::Encoders::Debug

Debug Encoder

Fast encoder producing simple debug output.

It is readable and diff-able and is used for testing.

You cannot fully restore the tokens information from the output, because consecutive :space tokens are merged. Use CodeRay::Tokens#dump for caching purposes.
