Installation

Requirements

• C++17 compatible compiler
• (Optional) Google Test for tests (included as submodule)
• (Optional) Doxygen for API documentation generation

$ git clone https://github.com/foxcpp/wire
$ cd wire
$ mkdir build; cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release
$ cmake --build .

Note 1 By default libwire will be built as a static library, if you want a shared library then you should add -DBUILD_SHARED_LIBS=ON flag.

Usage

Build system configuration

If you use CMake and clone libwire as a submodule, you can just link it this way:

add_subdirectory(wire/)
target_link_library(your-exectuable libwire)

It will use CMake magic to configure include path and other stuff.

Alternatively, you can access system-installed version using find_package.

find_package(libwire REQUIRED)
target_link_library(your-executable libwire)

In code

Let's write a simple TCP server that echoes back \n-terminated strings.

First, include TCP listener header:

#include <libwire/tcp/listener.hpp>

Then... It's very short so it doesn't needs any commentary:

using namespace libwire;

tcp::listener listener{ipv4::any, 7};

while (true) {
    auto sock = listener.accept();
    auto str = sock.read_until<std::string>('\n');
    sock.write(str);
}

Examples

See examples/ directory for sources and documentation for detailed description.

Documentation

Maintained in Markdown format (for separate page) and as a docstrings in code (for reference). Documentation for lastest commit in master is availiable here. You can also build it locally by running make doc. Ouput will be placed in doxygen_output/ directory.

Note Undocumented public function which behavior is not obvious is A BUG. Report it!

Contributing

Here is some of the ways that you can contribute:

• Submit a bug report. We love hearing about broken things, so that we can fix them.
• Provide feedback. Even simple questions about how things work or why they were done a certain way carries value.
• Test code. Checkout dev branch, compile it and start trying to break stuff! :-)
• Write code. Check issues marked with help wanted tag.
