pHPrintStringNoColor :: MonadIO m => Handle -> String -> m ()pretty-simple Text.Pretty.Simple Like pPrintStringNoColor, but take a Handle to determine where to print to.
>>> pHPrintStringNoColor stdout $ show $ Just ["hello", "bye"] Just [ "hello" , "bye" ]
pHPrintStringOpt :: MonadIO m => CheckColorTty -> OutputOptions -> Handle -> String -> m ()pretty-simple Text.Pretty.Simple Similar to pPrintStringOpt, but take a Handle to determine where to print to.
>>> let foo = show (1, (2, "hello", 3)) >>> pHPrintStringOpt CheckColorTty defaultOutputOptionsNoColor stdout foo ( 1 , ( 2 , "hello" , 3 ) )
pPrint :: (MonadIO m, Show a) => a -> m ()pretty-simple Text.Pretty.Simple Pretty-print any data type that has a Show instance. If you've never seen MonadIO before, you can think of this function as having the following type signature:
pPrint :: Show a => a -> IO ()
This function will only use colors if it detects it's printing to a TTY. This function is for printing to a dark background. Use pPrintLightBg for printing to a terminal with a light background. Different colors are used. Prints to stdout. Use pHPrint to print to a different Handle.>>> pPrint [Just (1, "hello")] [ Just ( 1 , "hello" ) ]
pPrintDarkBg :: (MonadIO m, Show a) => a -> m ()pretty-simple Text.Pretty.Simple Alias for pPrint.
pPrintForceColor :: (MonadIO m, Show a) => a -> m ()pretty-simple Text.Pretty.Simple Similar to pPrint, but print in color regardless of whether the output goes to a TTY or not. See pPrint for an example of how to use this function.
pPrintForceColorDarkBg :: (MonadIO m, Show a) => a -> m ()pretty-simple Text.Pretty.Simple Alias for pPrintForceColor.
pPrintForceColorLightBg :: (MonadIO m, Show a) => a -> m ()pretty-simple Text.Pretty.Simple Just like pPrintForceColorDarkBg, but for printing to a light background.
pPrintLightBg :: (MonadIO m, Show a) => a -> m ()pretty-simple Text.Pretty.Simple Just like pPrintDarkBg, but for printing to a light background.
pPrintNoColor :: (MonadIO m, Show a) => a -> m ()pretty-simple Text.Pretty.Simple Similar to pPrint, but doesn't print in color. However, data types will still be indented nicely.
>>> pPrintNoColor $ Just ["hello", "bye"] Just [ "hello" , "bye" ]
pPrintOpt :: (MonadIO m, Show a) => CheckColorTty -> OutputOptions -> a -> m ()pretty-simple Text.Pretty.Simple Similar to pPrint but takes OutputOptions to change how the pretty-printing is done. For example, pPrintOpt can be used to make the indentation much smaller than normal. This is what the normal indentation looks like:
>>> pPrintOpt NoCheckColorTty defaultOutputOptionsNoColor $ Just ("hello", "bye") Just ( "hello" , "bye" )This is what smaller indentation looks like:>>> let smallIndent = defaultOutputOptionsNoColor {outputOptionsIndentAmount = 1} >>> pPrintOpt CheckColorTty smallIndent $ Just ("hello", "bye") Just ( "hello" , "bye" )Lines in strings get indented>>> pPrintOpt NoCheckColorTty defaultOutputOptionsNoColor (1, (2, "foo\nbar\nbaz", 3)) ( 1 , ( 2 , "foo bar baz" , 3 ) )
Lines get indented even in custom show instances>>> data Foo = Foo >>> instance Show Foo where show _ = "foo\nbar\nbaz" >>> pPrintOpt CheckColorTty defaultOutputOptionsNoColor (1, (2, Foo, 3)) ( 1 , ( 2 , foo bar baz , 3 ) )
CheckColorTty determines whether to test stdout for whether or not it is connected to a TTY. If set to NoCheckColorTty, then pPrintOpt won't check if stdout is a TTY. It will print in color depending on the value of outputOptionsColorOptions. If set to CheckColorTty, then pPrintOpt will check if stdout is conneted to a TTY. If stdout is determined to be connected to a TTY, then it will print in color depending on the value of outputOptionsColorOptions. If stdout is determined to NOT be connected to a TTY, then it will NOT print in color, regardless of the value of outputOptionsColorOptions.
