Generate document with doxygen.
Doxygen file located at doc/libcopp.doxyfile .
libcopp use cmake to generate makefile and switch build tools.
- [required] GCC or Clang or VC support ISO C++ 98 and upper
- [required] cmake 2.8.9 and upper
- [optional] gtest 1.6.0 and upper (better test supported)
- [optional] Boost.Test (Boost.Test supported)
- [required] masm (in vc)
- [optional] if using gtest, pthread is required.
1. make a build directory
mkdir build
2. run cmake command
cmake <libcopp dir> [options]
options can be cmake options. such as set compile toolchains, source directory or options of libcopp that control build actions. libcopp options are listed below:
-DBUILD_SHARED_LIBS=YES|NO [default=NO] enable build dynamic library.
-DLIBCOPP_ENABLE_SEGMENTED_STACKS=YES|NO [default=NO] enable split stack supported context.(it's only availabe in linux and gcc 4.7.0 or upper)
-DGTEST_ROOT=[path] set gtest library install prefix path
3. make libcopp
make [options]
4. run test [optional]
test/coroutine_test
5. install [optional]
make install
Or you can just copy include directory and libcopp.a in lib or lib64 into your project to use it.
Just include headers and linking library file of your platform to use libcopp
There is a simple example of using coroutine context below:
#include <cstdio>
#include <cstring>
#include <iostream>
#include <inttypes.h>
#include <stdint.h>
// include context header file
#include <libcopp/coroutine/coroutine_context_container.h>
// define a coroutine runner
class my_runner : public copp::detail::coroutine_runnable_base
{
public:
int operator()() {
// ... your code here ...printf("cortoutine %" PRIxPTR " exit and return %d.\n", (intptr_t)&co_obj, co_obj.get_ret_code());
copp::coroutine_context_default* addr = get_coroutine_context<copp::coroutine_context_default>();
std::cout<< "cortoutine "<< addr<< " is running."<< std::endl;
addr->yield();
std::cout<< "cortoutine "<< addr<< " is resumed."<< std::endl;
return 1;
}
};
int main() {
// create a coroutine
copp::coroutine_context_default co_obj;
std::cout<< "cortoutine "<< &co_obj<< " is created."<< std::endl;
// create a runner
my_runner runner;
// bind runner to coroutine object
co_obj.create(&runner);
// start a coroutine
co_obj.start();
// yield from runner
std::cout<< "cortoutine "<< &co_obj<< " is yield."<< std::endl;
co_obj.resume();
std::cout<< "cortoutine "<< &co_obj<< " exit and return "<< co_obj.get_ret_code()<< "."<< std::endl;
return 0;
}
And then, you can custom many function such as set your stack allocator, coroutine type and etc. by set your template parameters of coroutine context. Notice: One coroutine runner can only below to one coroutine context
There is a simple example of using coroutine task below:
#include <iostream>
// include task header file
#include <libcotask/task.h>
typedef cotask::task<> my_task_t;
int main(int argc, char* argv[]) {
// create a task using factory function [with lambda expression]
my_task_t::prt_t task = my_task_t::create([](){
std::cout<< "task "<< cotask::this_task::get_task()->get_id()<< " started"<< std::endl;
cotask::this_task::get_task()->yield();
std::cout<< "task "<< cotask::this_task::get_task()->get_id()<< " resumed"<< std::endl;
return 0;
});
std::cout<< "task "<< task->get_id()<< " created"<< std::endl;
// start a task
task->start();
std::cout<< "task "<< task->get_id()<< " yield"<< std::endl;
task->resume();
std::cout<< "task "<< task->get_id()<< " stoped, ready to be destroyed."<< std::endl;
return 0;
}
And then, you can custom many functions by set your macro type of coroutine and task to do some other function.
split stack support: if in Linux and user gcc 4.7.0 or upper, add -DLIBCOPP_ENABLE_SEGMENTED_STACKS=YES to use split stack supported context.
