Tag Declaration

rascal-0.40.17

Synopsis​

Tag declarations are not implemented (yet).

Description​

Tag declarations explain which type the expected value of a tag should have.

Benefits​

  • They help the type checker to find common errors and they can help the parser to parse the contents of a string tag using a context-free grammar declaration.

Pitfalls​

  • Not yet implemented, so basically tags are not checked
