Fields

• getAttr :: Attr

Instances

Monoid AttrMonoid

We want mempty to be defAttr instead of currentAttr for use in combineSpans.

Methods

mempty :: AttrMonoid

mappend :: AttrMonoid -> AttrMonoid -> AttrMonoid

mconcat :: [AttrMonoid] -> AttrMonoid

applyAttrs :: RenderInfo -> Image

Apply a list of styles to the given text, resulting in a Image.

textAndStylesToImage :: [(Coord, Attr)] -> [YiString] -> Image

Makes and image from text and styles

attrLine :: [(Coord, Attr)] -> YiString -> Image

Applies the list of attrs to the line and returns a Image. It assumes that the list contains only Coords on the same line (i.e. row == 0)

Should be able to clean this up and provide better guarantees if I do a scan over attrs and get each successive mappend of them, then do T.splitAt for each offset, then apply the attr for each section at the begining of each of T.lines within each group. Ugly I know.

pairLines :: [(Coord, b)] -> [a] -> [([(Coord, b)], a)]

Pairs up lines with their styles.

decrRow :: [(Coord, a)] -> [(Coord, a)]

Decrements the row of all future attrs' location

decrCol :: Int -> [(Coord, a)] -> [(Coord, a)]

Decrements the column of all future attrs' location by the given amount

plainText :: YiString -> Image

Creates a text image without any new attributes.
