Lib CFG

Lib CFG - A small C++11 library for configuration file handling, CVars and Commands. Inspired by the in-game console of games like Quake and DOOM.

The whole library is contained into two source files, cfg.hpp and cfg.cpp, so it should be easy to integrate it into other projects. There are no external dependencies, besides the C and C++ Standard libraries. Some basic C++11 features are required. Exceptions and RTTI are not used, so it should compile cleanly with -fno-exceptions and -fno-rtti.

Registering commands:

cfg::CommandManager * cmdManager = cfg::CommandManager::createInstance();

// You can also register plain functions and member functions as command handlers!
cmdManager->registerCommand("my_cmd",
        [](const cfg::CommandArgs & args)
        {
            std::cout << "Running my_cmd with arguments:\n";
            for (auto arg : args)
            {
                std::cout << "> " << arg << "\n";
            }
        });

// Run the commands:
cmdManager->execAppend("my_cmd \"hello commands world!\" \'another arg for my_cmd.\'\n");
cmdManager->execBufferedCommands();

Registering CVars:

cfg::CVarManager * cvarManager = cfg::CVarManager::createInstance();

cfg::CVar * bVar = cvarManager->registerCVarBool("bVar", "a boolean", cfg::CVar::Flags::RangeCheck, true);
CFG_ASSERT(bVar->getBoolValue()   ==  true);
CFG_ASSERT(bVar->getStringValue() == "true");

cfg::CVar * iVar = cvarManager->registerCVarInt("iVar", "an integer", cfg::CVar::Flags::RangeCheck, 10, -10, +10);
CFG_ASSERT(iVar->getIntValue()    ==  10);
CFG_ASSERT(iVar->getStringValue() == "10");

cfg::CVar * fVar = cvarManager->registerCVarFloat("fVar", "a float", cfg::CVar::Flags::RangeCheck, 0.5, -1.0, +1.0);
CFG_ASSERT(fVar->getFloatValue()  ==  0.5);
CFG_ASSERT(fVar->getStringValue() == "0.5");
