-- String buffer facilities.
--
-- Lua's string operations are very flexible and offer an easy-to-use way to
-- manipulate strings. Concatenation using the <code>..</code> operator is such
-- an operation. The drawback of the built-in API however is the way it handles
-- concatenation of many string values. Since strings in Lua are immutable
-- values, each time you concatenate two strings both get copied into the
-- result string.
--
-- The <code>strbuf</code> module offers a workaround for this problem, while
-- maintaining the nice syntax. This is accomplished by overloading the
-- concatenation operator (<code>..</code>), the equality operator (<code>==</code>) and the <code>tostring</code>
-- operator. A string buffer is created by passing a string to
-- <code>strbuf.new</code>. Afterwards you can append to the string buffer,
-- or compare two string buffers for equality just as you would do with normal
-- strings.
--
-- When looking at the details there are some more restrictions/oddities: The
-- concatenation operator requires its left-hand value to be a string buffer.
-- Therefore, if you want to prepend a string to a given string buffer you have
-- to create a new string buffer out of the string you want to prepend. The
-- string buffer's <code>tostring</code> operator concatenates the strings
-- inside the buffer using newlines by default, since this appears to be the
-- separator used most often.
--
-- Example usage:
-- <code>
-- local buf = strbuf.new()
-- local buf2 = strbuf.new('hello')
-- buf = buf .. 'string'
-- buf = buf .. 'data'
-- print(buf)                   -- default separator is a newline
-- print(strbuf.dump(buf))      -- no separator
-- print(strbuf.dump(buf, ' ')) -- separated by spaces
-- strbuf.clear(buf)
-- </code>
