String manipulation utilities

Documentation

isBlank :: YiString -> Bool

chomp :: String -> String -> String

Remove any trailing strings matching irs (input record separator) from input string. Like perl's chomp(1).

capitalize :: String -> String

capitalizeFirst :: YiString -> YiString

dropSpace :: String -> String

Trim spaces at beginning and end

fillText :: Int -> YiString -> [YiString]

Fills lines up to the given length, splitting the text up if necessary.

onLines :: ([YiString] -> [YiString]) -> YiString -> YiString

mapLines :: (YiString -> YiString) -> YiString -> YiString

A helper function for creating functions suitable for modifySelectionB and modifyRegionB. To be used when the desired function should map across the lines of a region.

lines' :: Text -> [Text]

Split a Text in lines. Unlike lines, this does not remove any empty line at the end.

unlines' :: [Text] -> Text

Inverse of lines'. In contrast to unlines, this does not add an empty line at the end.

padLeft :: Int -> String -> String

padRight :: Int -> String -> String

commonTPrefix :: [Text] -> Maybe Text

Works by resupplying the found prefix back into the list, eventually either finding the prefix or not matching.

commonTPrefix' :: [Text] -> Text

Like commonTPrefix but returns empty text on failure.

listify :: [YiString] -> YiString

This is kind of like the default Show instance for lists except over Text. It does not leave the elements in extra quotes and should not be attempted to be shown and read back.

showT :: Show a => a -> Text

Helper that shows then packs the Text, for all those cases where we use show.

overInit :: (YiString -> YiString) -> YiString -> YiString

overInit f runs f over the init of the input if possible, preserving the last element as-is. If given a string with length ≤ 1, it effectively does nothing.

Also see overTail.

overTail :: (YiString -> YiString) -> YiString -> YiString

overInit f runs f over the tail of the input if possible, preserving the head element as-is. If given a string with length ≤ 1, it effectively does nothing.

Also see overInit.
