Hello one and all, Amid much editing, my Haskell version of protocol-buffer is now released at version 1.0.0. This version supports the feaures of Google's version 2.0.2 including the new extensible options. What is this for? What does it do? Why? It generates Haskell data types that can be converted back and forth to lazy ByteStrings that interoperate with Google's generated code in C++/Java/python. The data types are defined in a ".proto" text file which is translated into the target language. My code is a pure Haskell re-implementation of the Google code at http://code.Google.com/apis/protocolbuffers/docs/overview.html which is "...a language-neutral, platform-neutral, extensible way of serializing structured data for use in communications protocols, data storage, and more." Google's project produces C++, Java, and Python code. This one produces Haskell code. Where is the code? http://hackage.haskell.org/cgi-bin/hackage-scripts/package/protocol-buffers http://hackage.haskell.org/cgi-bin/hackage-scripts/package/protocol-buffers-... http://hackage.haskell.org/cgi-bin/hackage-scripts/package/hprotoc-1.0.0 And it needs to be build and installed in the above order. The first is the support library (Text.ProtocolBuffers). The second is the self-describing descriptor library (Text.DescriptorProtos[.Options]). The third is the 'hprotoc' executable which translates the ".proto" files into Haskell code. This works similarly to the "protoc" program from the original Google project. Cheers, Chris
