Is there a way to have a beautiful diff as I seen a while ago for OpenGL specification?

In OpenGL specification with diff marked (with colors), it was possible to easily just read changed sections.

I did a side by side comparison of the man-pages and posted it to a site that has the bindings I use, if it helps. Sorry no colors though.

http://groups.google.fr/group/nativelib ... 5ff128b917 (http://groups.google.fr/group/nativelibs4java/browse_thread/thread/a53b935ff128b917)

FYI, there is a very small problem with the HTML title of new man-pages. It still says 1.0 up on the browser tab.

Sorry, I forgot that forum reqd joining (we were getting spam posts, and that was our solution). Here it is below. FYI, the Changes appendix in the spec has a couple more that I missed, but it is not at the parameter level like this.

New 3-element vector types: int3, float3, char3, double3, etc.

clGetDeviceInfo() has new cl_device_info values:
CL_DEVICE_EXTENSIONS missing extensions. These I guess are mandatory. Image support is still optional, but cl_khr_3d_images_writes missing means if image supported than 3d writes reqd.
cl_khr_select_fprounding_mode
cl_khr_global_int32_base_atomics
cl_khr_global_int32_extended_atomics
cl_khr_local_int32_base_atomics
cl_khr_local_int32_extended_atomics
cl_khr_3d_images_writes
cl_khr_byte_addressable_store
CL_DEVICE_HOST_UNIFIED_MEMORY
CL_DEVICE_NATIVE_VECTOR_WIDTH_CHAR
CL_DEVICE_NATIVE_VECTOR_WIDTH_SHORT
CL_DEVICE_NATIVE_VECTOR_WIDTH_INT
CL_DEVICE_NATIVE_VECTOR_WIDTH_LONG
CL_DEVICE_NATIVE_VECTOR_WIDTH_FLOAT
CL_DEVICE_NATIVE_VECTOR_WIDTH_DOUBLE
CL_DEVICE_NATIVE_VECTOR_WIDTH_HALF

clCreateContext() & clCreateContextFromType() has new cl_context_properties values:
CL_CONTEXT_D3D10_DEVICE_KHR
CL_GL_CONTEXT_KHR
CL_EGL_DISPLAY_KHR
CL_GLX_DISPLAY_KHR
CL_WGL_HDC_KHR
CL_CGL_SHAREGROUP_KHR

clGetContextInfo() has new cl_context_info values:
CL_CONTEXT_NUM_DEVICES
CL_CONTEXT_D3D10_PREFER_SHARED_RESOURCES_KHR

clGetEventInfo() has new cl_command_type values:
CL_COMMAND_READ_BUFFER_RECT
CL_COMMAND_WRITE_BUFFER_RECT
CL_COMMAND_COPY_BUFFER_RECT
CL_COMMAND_USER
CL_COMMAND_GL_FENCE_SYNC_OBJECT_KHR
CL_COMMAND_ACQUIRE_D3D10_OBJECTS_KHR
CL_COMMAND_RELEASE_D3D10_OBJECTS_KHR

clGetImageInfo() has new cl_image_info values:
CL_IMAGE_D3D10_SUBRESOURCE_KHR

clGetKernelWorkGroupInfo() has new cl_kernel_work_group_info values:
CL_KERNEL_PREFERRED_WORK_GROUP_SIZE_MULTIPLE
CL_KERNEL_PRIVATE_MEM_SIZE

clGetMemObjectInfo() has new cl_mem_info values:
CL_MEM_ASSOCIATED_MEMOBJECT
CL_MEM_OFFSET
CL_MEM_D3D10_RESOURCE_KHR

new API calls:
clCreateEventFromGLsyncKHR()
clCreateFromD3D10BufferKHR()
clCreateFromD3D10Texture2DKHR()
clCreateFromD3D10Texture3DKHR()
clCreateSubBuffer()
clCreateUserEvent()
clEnqueueAcquireD3D10ObjectsKHR()
clEnqueueCopyBufferRect()
clEnqueueReadBufferRect()
clEnqueueReleaseD3D10ObjectsKHR()
clEnqueueWriteBufferRect()
clGetGLContextInfoKHR()
clSetEventCallback()
clSetMemObjectDestructorCallback()
clSetUserEventStatus()

Depreciated API calls:
clSetCommandQueueProperty

New kernel functions:
get_global_offset()
maxmag()
minmag()

I did a blog on it last week: http://www.streamcomputing.nl/blog/2010 ... -1-changes (http://www.streamcomputing.nl/blog/2010-06-23/opencl-1-1-changes)
Hope that helps?
