List processing
splitBy :: (a -> Bool) -> [a] -> [[a]]
Split list by groups of one or more sep.
splitByIndices :: [Int] -> [a] -> [[a]]
splitStringByIndices :: [Int] -> [Char] -> [[Char]]
Split string into chunks divided at specified indices.
substitute :: Eq a => [a] -> [a] -> [a] -> [a]
Replace each occurrence of one sublist in a list with another.
Text processing
Arguments
:: [Char] | list of special characters to escape |
-> [(Char, String)] |
Returns an association list of backslash escapes for the designated characters.
escapeStringUsing :: [(Char, String)] -> String -> String
Escape a string of characters, using an association list of characters and strings.
stripTrailingNewlines :: String -> String
Strip trailing newlines from string.
trim :: String -> String
Remove leading and trailing space (including newlines) from string.
triml :: String -> String
Remove leading space (including newlines) from string.
trimr :: String -> String
Remove trailing space (including newlines) from string.
stripFirstAndLast :: String -> String
Strip leading and trailing characters from string
camelCaseToHyphenated :: String -> String
Change CamelCase word to hyphenated lowercase (e.g., camel-case).
toRomanNumeral :: Int -> String
Convert number < 4000 to uppercase roman numeral.
escapeURI :: String -> String
Escape whitespace in URI.
Arguments
:: Int | Tab stop |
-> String | Input |
-> String |
Convert tabs to spaces and filter out DOS line endings. Tabs will be preserved if tab stop is set to 0.
Date/time
normalizeDate :: String -> Maybe String
Parse a date and convert (if possible) to YYYY-MM-DD format.
Pandoc block and inline list processing
orderedListMarkers :: (Int, ListNumberStyle, ListNumberDelim) -> [String]
Generate infinite lazy list of markers for an ordered list, depending on list attributes.
normalizeSpaces :: [Inline] -> [Inline]
Normalize a list of inline elements: remove leading and trailing
Space
elements, collapse double Space
s into singles, and
remove empty Str elements.
Change final list item from Para
to Plain
if the list contains
no other Para
blocks.
Change final list item from Para
to Plain
if the list contains
no other Para
blocks. Like compactify, but operates on Blocks
rather
than [Block]
.
data Element
Data structure for defining hierarchical Pandoc documents
hierarchicalize :: [Block] -> [Element]
Convert list of Pandoc blocks into (hierarchical) list of Elements
uniqueIdent :: [Inline] -> [String] -> String
Generate a unique identifier from a list of inlines. Second argument is a list of already used identifiers.
isHeaderBlock :: Block -> Bool
True if block is a Header block.
headerShift :: Int -> Pandoc -> Pandoc
Shift header levels up or down.
isTightList :: [[Block]] -> Bool
Detect if a list is tight.
TagSoup HTML handling
renderTags' :: [Tag String] -> String
Render HTML tags.
File handling
inDirectory :: FilePath -> IO a -> IO a
Perform an IO action in a directory, returning to starting directory.
readDataFile :: Maybe FilePath -> FilePath -> IO ByteString
Read file from specified user data directory or, if not found there, from Cabal data directory.
readDataFileUTF8 :: Maybe FilePath -> FilePath -> IO String
Same as readDataFile
but returns a String instead of a ByteString.
fetchItem :: String -> String -> IO (ByteString, Maybe String)
Fetch an image or other item from the local filesystem or the net. Returns raw content and maybe mime type.
openURL :: String -> IO (ByteString, Maybe String)
Read from a URL and return raw data and maybe mime type.
Error handling
err :: Int -> String -> IO a
warn :: String -> IO ()
Safe read
safeRead :: (Monad m, Read a) => String -> m a
