Upgrading v0.8 to v0.9

Updating the Code

v0.9 includes a major overhaul of the C++ API for creating values. If you haven't already been using a git version from sometime in the last two/three months, this is going to break any C++ code from previous versions. Sorry, but it's worth it and not that hard to get working again. Basically you need to change from this:

object env = create_object();

to be this instead:

object env = create< object >();

Similarly for array, string, natives etc. This new create api is much more powerful -- and too much to go into here, check out the docs for it : <http://flusspferd.org/docs/group__create.html#ga4330a9ba851b6f11a49654bcec110d6a> (there will be a more permanent url when 0.9 is released)

Updating the CFlags

If when compiling you get an error like this:

/usr/local/include/flusspferd/create/native_object.hpp:95: error: wrong number of template arguments (6, should be 5)
/usr/local/include/boost/parameter/parameters.hpp:714: error: provided for ‘template<class PS0, class PS1, class PS2, class PS3, class PS4> struct boost::parameter::parameters’

It means you are missing a define, namely: -DBOOST_PARAMETER_MAX_ARITY=10 The pkg-config file has these changes, and if you are just compiling a plugin module (rather than embedding flusspferd itself) We've made it easier for you. Simply create a CMakeLists.txt in your module root, and have it contain something like this:

cmake_minimum_required(VERSION 2.6.4)

execute_process( COMMAND flusspferd --cmake OUTPUT_VARIABLE hippo_cmake) 
include("${hippo_cmake}")

if(NOT CMAKE_BUILD_TYPE)
    set( CMAKE_BUILD_TYPE Release CACHE STRING
        "Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel." 
        FORCE)
endif()

FILE(GLOB_RECURSE sources 
     "${CMAKE_SOURCE_DIR}/src/*.cpp" 
     "${CMAKE_SOURCE_DIR}/src/*.hpp")

add_definitions("-Wall")
flusspferd_plugin(
  "zest" 
  SOURCES ${sources})

Other things you can pass to "flusspferd_plugin" are:

- JS - js files to install along with native module
- LIBRARIES - libraries to use at link time; and
- DEFINITIONS - C++ definitions to define at compile time.

If you have any problems that aren't described above, or any of the fixes dont work, come grab us on irc://irc.freenode.net/#flusspferd or on the mailing list http://groups.google.com/group/flusspferd.
