Arguments
| :: FilePath | File for error reports |
| -> [(String, String)] | Pre-defined symbols and their values |
| -> [String] | Search path for #includes |
| -> Bool | Leave #define and #undef in output? |
| -> Bool | Place #line droppings in output? |
| -> String | The input file content |
| -> [(Posn, String)] | The file after processing (in lines) |
Run a first pass of cpp, evaluating #ifdef's and processing #include's, whilst taking account of #define's and #undef's as we encounter them.
Arguments
| :: [(String, String)] | Pre-defined symbols and their values |
| -> Bool | Strip C-comments? |
| -> Bool | Accept # and ## operators? |
| -> Bool | Retain layout in macros? |
| -> Bool | Input language (Haskell/not) |
| -> [(Posn, String)] | The input file content |
| -> String | The file after processing |
Walk through the document, replacing calls of macros with their expanded RHS.
