Hello, I'm pleased to announce the first release of the sexpresso [0] library on Hackage. sexpresso is a library to parse, print and work with S-expression. You can for example : - Customize the opening and closing tag, usually '(' and ')'. - Specify if space is needed between atoms (or between only a subset of atoms) - The datatype for S-expression (SExpr) has a extra parameter to make parsing, working and printing with multiple "type" of S-expression, like Scheme list (...) and Scheme vector #(....), easier - Do much more ... read the doc on Hackage or the README on github [1] ! I plan to improve the printer and add recursive scheme soon. [0] http://hackage.haskell.org/package/sexpresso [1] https://github.com/archambaultv/sexpresso Vincent Archambault
