Pros of Weasel

• Weasel is a more lightweight and minimalist input method editor (IME) compared to Squirrel.
• Weasel has a smaller codebase and faster startup time, making it more suitable for low-resource environments.
• Weasel supports a wider range of platforms, including Windows, macOS, and Linux.

Cons of Weasel

• Weasel has fewer features and customization options compared to Squirrel.
• Weasel may not have the same level of community support and active development as Squirrel.
• Weasel's user interface and user experience may not be as polished as Squirrel's.

Code Comparison

Here's a brief code comparison between Weasel and Squirrel:

Weasel (main.cpp):

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    // Initialize Weasel
    Weasel::Initialize(hInstance);

    // Run the main message loop
    Weasel::Run();

    // Uninitialize Weasel
    Weasel::Uninitialize();

    return 0;
}

Squirrel (main.cpp):

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    // Initialize Squirrel
    Squirrel::Initialize(hInstance);

    // Run the main message loop
    Squirrel::Run();

    // Uninitialize Squirrel
    Squirrel::Uninitialize();

    return 0;
}

As you can see, the main entry point and initialization/run/uninitialize process are very similar between the two projects, reflecting their shared purpose as IME frameworks.

Pros of librime

• librime is a cross-platform library for Rime input method engine, allowing for easy integration into various applications.
• librime provides a more comprehensive set of features and functionality compared to Squirrel, making it a more robust and flexible solution.
• librime has a larger community and more active development, ensuring better long-term support and maintenance.

Cons of librime

• librime has a steeper learning curve and may require more technical expertise to integrate into a project.
• librime has a larger codebase and dependency footprint, which can be a drawback for projects with limited resources or specific requirements.
• librime may not be as lightweight and streamlined as Squirrel, which could be a consideration for certain use cases.

Code Comparison

librime (simplified):

class Composer {
public:
    void Compose(const std::string& input) {
        // Compose the input using the Rime engine
    }

    std::string GetComposition() const {
        // Return the current composition
    }
};

Squirrel (simplified):

class SquirrelEngine {
public:
    void ProcessInput(const std::string& input) {
        // Process the input and update the composition
    }

    std::string GetComposition() const {
        // Return the current composition
    }
};

Pros of OpenCC

• Supports a wide range of Chinese character conversion, including Simplified Chinese to Traditional Chinese, and vice versa.
• Provides a comprehensive set of dictionaries and conversion rules for various regional variants of Chinese.
• Actively maintained with regular updates and bug fixes.

Cons of OpenCC

• The project is primarily focused on Chinese character conversion, and may not have the same level of features or customization options as Squirrel.
• The documentation and community support may not be as extensive as Squirrel, which has a larger user base.

Code Comparison

OpenCC:

auto converter = opencc::SimpleConverter("s2t.json");
std::string converted = converter.Convert("你好");
std::cout << converted << std::endl; // 你好

Squirrel:

auto engine = rime::RimeApi::Create();
rime::RimeConfig config;
config.LoadFromFile("rime.yaml");
rime::RimeContext context;
engine->ProcessKey(&config, &context, RIME_KEY_SPACE);
std::string output = context.GetCommit();
std::cout << output << std::endl; // 你好
