red :: TTY -> Text -> Text Source #

Color text red

redBackground :: Orientation -> TTY -> Text -> Text Source #

Color text background red

green :: TTY -> Text -> Text Source #

Color text green

greenBackground :: Orientation -> TTY -> Text -> Text Source #

Color text background green

grey :: Orientation -> TTY -> Text -> Text Source #

Color text grey

minus :: TTY -> Text -> Text Source #

Format the left half of a diff

plus :: TTY -> Text -> Text Source #

Format the right half of a diff

explain :: Text -> Text Source #

Format text explaining a diff

renderWith :: Changed a -> ((Text -> Text, a) -> Render ()) -> Render () Source #

Utility to automate a common pattern of printing the two halves of a diff. This passes the correct formatting function to each half

renderOutputs :: Set Text -> Text Source #

Format the derivation outputs
