Instances
insertSemi :: [GoTokenPos] -> [GoTokenPos]Source
insertSemi performs semicolon insertion.
stripComments :: [GoTokenPos] -> [GoTokenPos]Source
tokenFromComment :: Bool -> String -> GoTokenSource
tokenFromInt :: String -> GoTokenSource
tokenFromReal :: String -> GoTokenSource
tokenFromImag :: String -> GoTokenSource
tokenFromChar :: String -> GoTokenSource
tokenFromChar c unquotes the Go representation of a single
character literal, including the single quotes.
unquoteChar :: String -> Maybe CharSource
unquoteString :: String -> Maybe StringSource
Parsers for elementary punctuation
