-- | Multiline strings, interpolation and templating.
--   
--   This package adds quasiquoter for multiline strings, interpolation and
--   simple templating. It can handle repetition templates which makes it
--   Handy for outputting larger structures, such as latex tables or
--   gnuplot files.
@package Interpolation
@version 0.2.2

module Data.String.Interpolation

-- | Quasiquote <a>str</a> implements multiline strings with interpolation.
--   Interpolating a value into the string is done by $&lt;String
--   expression&gt;$ and interpolating anything with instance Show is
--   $:&lt;Show expression&gt;$. Due to pretty deep limitations, the parser
--   is not able to properly deduce associtivity of infix operators, so use
--   lots and lots of parenthesis.
--   
--   Repetitive patterns can be made with # symbol:
--   
--   <pre>
--   #&lt;var&gt; in &lt;list&gt;: &lt;interpolated string&gt; (|&lt;interpolated string&gt;)#
--   </pre>
--   
--   Where (|&lt;interpolated string&gt;) denotes optional separator for
--   the elements.
--   
--   Multiline indentation is handled by aligning on smallest un-empty line
--   after the first. Neither pattern matching nor nested #-patterns are
--   supported. Normal '\\n' style escaping of special characters is
--   intentionally not supported. Please use $endline$ or $<a>n</a>$ style
--   instead. (Also, in this beta release $, and : symbols are not escaped
--   in the interpolated expressions.
--   
--   As an example, let's plot set of vectors with gnuplot:
--   
--   <pre>
--   plotVecs :: [(String,[Double])] -&gt; String
--   plotVecs vs =  
--       [$str| ## Plot multiple vectors
--              plot #(n,_) in vs:<a>-</a> with lines lw 5 title $n$ |, #
--              #d in map snd vs:$singleVec d$$endline$e$endline$# |]
--   where
--    singleVec n = [$str|#(e,i) in zip n [1..]: $:i$ $:e$|$endline$#|]
--   </pre>
--   
--   <pre>
--     *Gnuplotter&gt; plotVecs [(<a>A</a>,[1..5]),(<a>B</a>,[2..6])]
--     # Plot multiple vectors
--      plot <a>-</a> with lines lw 5 title A , <a>-</a> with lines lw 5 title B
