OK, thanks Ian. Using pragState on only the pragma line gives me the proper
token types, but on the whole Haskell input it fails, obviously I need to
combine the two lexer states to get the full lexing, but I can achieve what
I want anyway, I just wanted to understand.
Thank you
JP

let prTS = lexTokenStream sb lexLoc flg
This prints: ["ITblockComment \" CPP #\"","ITmodule","ITconid \"Main\"","ITwhere","ITvocurly","ITvarid \"main\"","ITequal","ITvarid \"undefined\""]
Why is the first token ITblockComment and not ITlanguage_prag? Do I need
to
enable something special to get pragma tokens?
lexTokenStream uses mkPState, but I think you need to use pragState to get the language pragmas. (see Lexer.x).
Thanks Ian
