runCpphsReturningSymTab :: CpphsOptions -> FilePath -> String -> IO (String, [(String, String)])Source
Arguments
| :: FilePath | File for error reports |
| -> [(String, String)] | Pre-defined symbols and their values |
| -> [String] | Search path for #includes |
| -> BoolOptions | Options controlling output style |
| -> String | The input file content |
| -> IO [(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 |
| -> BoolOptions | Options that alter processing style |
| -> [(Posn, String)] | The input file content |
| -> IO String | The file after processing |
Walk through the document, replacing calls of macros with the expanded RHS.
macroPassReturningSymTabSource
Arguments
| :: [(String, String)] | Pre-defined symbols and their values |
| -> BoolOptions | Options that alter processing style |
| -> [(Posn, String)] | The input file content |
| -> IO (String, [(String, String)]) | The file and symbol table after processing |
Walk through the document, replacing calls of macros with the expanded RHS. Additionally returns the active symbol table after processing.
data BoolOptions Source
Options representable as Booleans.

Fields

parseOptions :: [String] -> Either String CpphsOptionsSource
Parse all command-line options.
defaultCpphsOptions :: CpphsOptionsSource
Default options.
defaultBoolOptions :: BoolOptionsSource
Default settings of boolean options.
Source positions contain a filename, line, column, and an inclusion point, which is itself another source position, recursively.
