ewig

ewig是一个简单的文本编辑器（Ersatz Emacs），使用 C++ 中的不可变数据结构编写。

该代码以简单的风格编写，以展示基于价值的功能架构。我们邀请您研究代码。在CppCon'17 演讲中了解更多信息：后现代不可变数据结构。

该项目是帮助交互式和并发 C++ 程序变得更容易编写的长期愿景的一部分。通过成为赞助人或购买赞助套餐来帮助该项目的长期可持续性： [email protected]

尝试一下

如果您使用 Nix 包管理器（我们强烈推荐它），您只需安装该软件即可。

    nix-env -if https://github.com/arximboldi/ewig/archive/master.tar.gz

发展

要构建代码，您需要 C++17 编译器、 cmake和支持 unicode 的ncurses （Debian 及其朋友中的软件包libncursesw5-dev ）。

您可以手动安装它们，但启动并运行开发环境的最简单方法是使用 Nix 包管理器。在存储库的根目录中只需键入：

    nix-shell

这将下载所有必需的依赖项并创建一个隔离的环境，您可以在其中使用这些依赖项，而不会污染您的系统。

然后就可以使用CMake生成开发项目了。

    mkdir build && cd build
    cmake ..

要配置优化的构建和编译，请执行以下操作：

    cmake .. -DCMAKE_BUILD_TYPE=Release
    make

全局安装已编译的软件：

    sudo make install

键绑定

摘自main.cpp ：

 const auto key_map_emacs = make_key_map(
{
    { key::seq ( key::ctrl ( ' p ' )), " move-up " },
    { key::seq (key::up),        " move-up " },
    { key::seq (key::down),      " move-down " },
    { key::seq ( key::ctrl ( ' n ' )), " move-down " },
    { key::seq ( key::ctrl ( ' b ' )), " move-left " },
    { key::seq (key::left),      " move-left " },
    { key::seq ( key::ctrl ( ' f ' )), " move-right " },
    { key::seq (key::right),     " move-right " },
    { key::seq (key::page_down), " page-down " },
    { key::seq (key::page_up),   " page-up " },
    { key::seq (key::backspace), " delete-char " },
    { key::seq (key::backspace_), " delete-char " },
    { key::seq (key::delete_),   " delete-char-right " },
    { key::seq (key::home),      " move-beginning-of-line " },
    { key::seq ( key::ctrl ( ' a ' )), " move-beginning-of-line " },
    { key::seq (key::end),       " move-end-of-line " },
    { key::seq ( key::ctrl ( ' e ' )), " move-end-of-line " },
    { key::seq ( key::ctrl ( ' i ' )), " insert-tab " }, // tab
    { key::seq ( key::ctrl ( ' j ' )), " new-line " }, // enter
    { key::seq ( key::ctrl ( ' k ' )), " kill-line " },
    { key::seq ( key::ctrl ( ' w ' )), " cut " },
    { key::seq ( key::ctrl ( ' y ' )), " paste " },
    { key::seq ( key::ctrl ( ' @ ' )), " start-selection " }, // ctrl-space
    { key::seq ( key::ctrl ( ' _ ' )), " undo " },
    { key::seq ( key::ctrl ( ' x ' ), key::ctrl ( ' C ' )), " quit " },
    { key::seq ( key::ctrl ( ' x ' ), key::ctrl ( ' S ' )), " save " },
    { key::seq ( key::ctrl ( ' x ' ), ' h ' ), " select-whole-buffer " },
    { key::seq ( key::ctrl ( ' x ' ), ' [ ' ), " move-beginning-buffer " },
    { key::seq ( key::ctrl ( ' x ' ), ' ] ' ), " move-end-buffer " },
    { key::seq ( key::alt ( ' w ' )),  " copy " },
});
