-- | Haskell source code formatter
--   
--   The Haskell Formatter formats Haskell source code. It is strict in
--   that it fundamentally rearranges code.
@package haskell-formatter

module Language.Haskell.Formatter.Internal.Newline

-- | Unicode newline strings ordered by descending length. This corresponds
--   to the set of newlines from
--   <a>http://www.unicode.org/standard/reports/tr13/tr13-5.html</a>.
newlines :: [String]

-- | Concatenates strings with default newlines <tt>"\n"</tt> between.
--   
--   Unlike <a>unlines</a>, this does not append a newline to the last
--   string.
--   
--   <pre>
--   &gt;&gt;&gt; joinSeparatedLines ["apple", "pine"]
--   "apple\npine" 
--   </pre>
joinSeparatedLines :: [String] -> String

-- | Breaks a string up into its lines at <a>newlines</a>. The resulting
--   strings do not contain <a>newlines</a>.
--   
--   Unlike <a>lines</a>, this interprets a newline as a separator, not a
--   terminator. Thus, if the input string ends with a newline, the output
--   list ends with the empty string.
