Merge pull request #2066 from KvanTTT/unreachable-tokens 
New unreachable token value warning
 2017-12-06 12:35:53 -08:00
Nicolas d2685bf37f Add a test case for merging clashing channel names during import. 2017-12-04 17:35:08 +13:00
Nicolas 0301bb946c Add a test case for importing modal lexers into a composite grammar. The 
test case demonstrates an error is produced (due to importing modes into a
composite grammar).
 2017-11-30 23:24:11 +13:00
Nicolas d02844c813 This is one implementation addressing issue 160. 
Change to support import of lexer grammars containing modes into other
lexer grammars. The semantics for this are,
   * sets of channels from all grammars are merged
   * rules of modes found in an imported grammar which are in the root
     grammar are merged into the root grammar mode.
   * modes which are not in the root grammar are added to the root
     grammar, excluding modes which become empty due to a re-definition of
     rules in the root grammar.
