Hi, cpp easily gets confused by single primes in variables names, which do not exist in C. You can use a better suited cpp implementation, such as http://projects.haskell.org/cpphs/ Greetings, Joachim Am Freitag, den 11.08.2017, 18:25 +0300 schrieb Baa:
Hello, Dear List!
I have code (this is the fragment only):
{-# LANGUAGE CPP #-} ... ... let user' = ... ... else defect $ logger # ("authentication failure (user: " ++ user' ++ ")") #: __LINE__ ... ...
and I get compilation error:
• Found hole: __LINE__ :: Int Or perhaps ‘__LINE__’ is mis-spelled, or not in scope • In the second argument of ‘(#:)’, namely ‘__LINE__’ In the second argument of ‘($)’, namely ‘logger # ("authentication failure (user: " ++ user' ++ ")") #: __LINE__’ In the expression: defect $ logger # ("authentication failure (user: " ++ user' ++ ")") #: __LINE__ • Relevant bindings include... ... etc ...
But if I change variable name to `userx` (from user'), all is compiled succesflully, no any holes. Where is the hole?
