Based on #347, I created the lexer in golang.


  • Keywords based on RFC7950
  • Seperating keywords in groups, based on BNF definition of RFC7950 for maintenance
  • Highlighting of constants, like true, false or deprecated with special token
  • Highlighting of namespace-prefix, like type namespace-prefix:counter64;. namespace-prefix will have special token.
    For example namespace urn:ieee:std:802.1AX:yang:ieee802-dot1ax; will have no special token
  • Prefix-highlighting should be the complex regex pattern of all pattern. Due to that, I created test cases to validate prefix-highlighting
  • Add some test cases for testing of another complex scenarios, like revision-date
  • Create example yang file for testing
