Documentation

data ColModInfo

Specifies how a column should be modified. Values of this type are derived in a traversal over the input columns by using deriveColModInfos. Finally, columnModifier will interpret them and apply the appropriate modification function to the cells of the column.

Constructors

FillAligned OccSpec AlignInfo

FillTo Int

FitTo Int (Maybe (OccSpec, AlignInfo))

showCMI :: ColModInfo -> String

Private show function.

widthCMI :: ColModInfo -> Int

Get the exact width of a ColModInfo after applying it with columnModifier.

unalignedCMI :: ColModInfo -> ColModInfo

Remove alignment from a ColModInfo. This is used to change alignment of headers while using the combined width information.

ensureWidthCMI :: Int -> Position H -> ColModInfo -> ColModInfo

Ensures that the modification provides a minimum width but only if it is not limited.

ensureWidthOfCMI :: String -> Position H -> ColModInfo -> ColModInfo

Ensures that the given String will fit into the modified columns.

fitTitlesCMI :: [String] -> [Position H] -> [ColModInfo] -> [ColModInfo]

Fit titles of a header column into the derived ColModInfo.

columnModifier :: (Cell a, StringBuilder b) => Position H -> CutMark -> ColModInfo -> a -> b

Generates a function which modifies a given cell according to Position, CutMark and ColModInfo. This is used to modify a single cell of a column to bring all cells of a column to the same width.

deriveColModInfos :: Cell a => [(LenSpec, AlignSpec)] -> [Row a] -> [ColModInfo]

Derive the ColModInfo by using layout specifications and the actual cells of a column. This function only needs to know about LenSpec and AlignInfo.

deriveColModInfos' :: Cell a => [ColSpec] -> [Row a] -> [ColModInfo]

deriveColMods :: (Cell a, StringBuilder b) => [ColSpec] -> [Row a] -> [a -> b]

Derive the ColModInfo and generate functions without any intermediate steps.

deriveAlignInfo :: Cell a => OccSpec -> a -> AlignInfo

Generate the AlignInfo of a cell by using the OccSpec.
