This project is currently in alpha, and contains no compiler. A scanner and parser are being developed to support a future compiler.To help, check out parser. This project contains tests that iterate through sass-spec running the parser against example inputs. Errors detected by the parser are reported. However, you could also set the Parser mode to Trace and verify proper ast trees are being built from the input. As the parser matures, output can automatically be verified by the example outputs in these directories.
