IMPORTANT: You do not have to build this library before using it. It is a header-only library. Many modern C++ libraries are developed this way and it makes them much easier to reuse - something we really want to encourage.
Comet is a library that provides a modern (STL-like) C++ interface around the complexities of Microsoft COM. It allows you to do both COM client and COM server programming, without any dependency on either ATL or MFC. Instead, it builds upon the C++ Standard Library that is included with every modern C++ compiler, regardless of platform.
Other versions of Comet are most likely version 1 gamma 32 plus or minus a few bugfixes. This is Comet version 2 because it breaks backward compatibility with those versions so that we can develop it more freely.
Comet was designed and implemented by Sofus Mortensen with contributions, ideas and bug fixes from Paul Hollingsworth, Michael Geddes, Mikael Lindgren, Kyle Alons and Vladimir Voinkov. This version of comet is maintained by Alexander Lamaison.
Just add comet/include to your compiler's include path and you are
ready to go.
If you're using CMake version 3 or above for your project, Comet can set itself up for you. Remember you don't have to compile Comet. The CMake files just make it easier to use in an existing CMake project.
find_package(Comet REQUIRED CONFIG)
target_link_libraries(my_project_target PRIVATE comet)
Because Comet is header-only, this doesn't link in the traditional sense. It just makes the target aware of Comet's usage requirements such as the include path. Referencing Comet this way means you don't have to change your build configuration if those requirements change in the future.
Of course, you have to make Comet available to your project. There are two ways to do this:
If you have a CMake 'superbuild' to pull in dependencies automatically, you can add Comet like this:
include(ExternalProject)
ExternalProject_Add(
Comet
URL https://github.com/alamaison/comet/archive/3.0.0.tar.gz
URL_HASH SHA1=dced97055d9ce593ffa52b0ba067ac04b0d96239
CMAKE_ARGS "-DBUILD_TESTING=NO"
INSTALL_COMMAND "")
ExternalProject_Add(
MyProject DEPENDS Comet
SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/src
INSTALL_COMMAND "")
When you build your super-project, CMake will download Comet, and
export its configuration to the user package registry where your
project will find it by calling find_package.
Download and configure Comet.
$ cmake -H . -B _builds -DBUILD_TESTING=NO
This will export it to the user package registry where your project
will find it by calling find_package.
The library is documented inline and you can use Doxygen to generate documentation for it if you want. Also, read the following articles. They are based on Comet v1 but, as yet, there isn't much difference.
And last but not least, the Comet version 1 documentation.
No, not really. We use Boost, but only for the test suite so you don't even need that.
