Language.Preprocessor.Cpphs.Options

Description

This module deals with Cpphs options and parsing them

Synopsis

data CpphsOptions = CpphsOptions {
- infiles :: [FilePath]
- outfiles :: [FilePath]
- defines :: [(String, String)]
- includes :: [String]
- preInclude :: [FilePath]
- boolopts :: BoolOptions
}
data BoolOptions = BoolOptions {
- macros :: Bool
- locations :: Bool
- hashline :: Bool
- pragma :: Bool
- stripEol :: Bool
- stripC89 :: Bool
- lang :: Bool
- ansi :: Bool
- layout :: Bool
- literate :: Bool
- warnings :: Bool
}
parseOptions :: [String] -> Either String CpphsOptions
defaultCpphsOptions :: CpphsOptions
defaultBoolOptions :: BoolOptions
trailing :: Eq a => [a] -> [a] -> [a]

Fields

macros :: Bool
Leave #define and #undef in output of ifdef?
locations :: Bool
Place #line droppings in output?
hashline :: Bool
Write #line or {-# LINE #-} ?
pragma :: Bool
Keep #pragma in final output?
stripEol :: Bool
Remove C eol (//) comments everywhere?
stripC89 :: Bool
Remove C inline (/**/) comments everywhere?
lang :: Bool
Lex input as Haskell code?
ansi :: Bool
Permit stringise # and catenate ## operators?

Instances

Show BoolOptions #
Instance details Defined in Language.Preprocessor.Cpphs.Options Methods showsPrec :: Int -> BoolOptions -> ShowS show :: BoolOptions -> String showList :: [BoolOptions] -> ShowS

parseOptions :: [String] -> Either String CpphsOptions #

Parse all command-line options.

defaultCpphsOptions :: CpphsOptions #

Default options.

defaultBoolOptions :: BoolOptions #

Default settings of boolean options.

trailing :: Eq a => [a] -> [a] -> [a] #

Trim trailing elements of the second list that match any from the first list. Typically used to remove trailing forward/back slashes from a directory path.
