runCpphsPass1 :: CpphsOptions -> FilePath -> String -> IO [(Posn, String)] Source
runCpphsPass2 :: BoolOptions -> [(String, String)] -> FilePath -> [(Posn, String)] -> IO String Source
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.
tokenise :: Bool -> Bool -> Bool -> Bool -> [(Posn, String)] -> [WordStyle] Source
tokenise is, broadly-speaking, Prelude.words, except that: * the input is already divided into lines * each word-like "token" is categorised as one of {Ident,Other,Cmd} * #define's are parsed and returned out-of-band using the Cmd variant * All whitespace is preserved intact as tokens. * C-comments are converted to white-space (depending on first param) * Parens and commas are tokens in their own right. * Any cpp line continuations are respected. No errors can be raised. The inverse of tokenise is (concatMap deWordStyle).
Each token is classified as one of Ident, Other, or Cmd: * Ident is a word that could potentially match a macro name. * Cmd is a complete cpp directive (#define etc). * Other is anything else.
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.
macroPassReturningSymTab Source
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.

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