ewig

ewig是一個簡單的文字編輯器（Ersatz Emacs），使用 C++ 中的不可變資料結構來編寫。

程式碼以簡單的風格編寫，以展示基於價值的功能架構。我們邀請您研究程式碼。在CppCon'17 演講中了解更多：後現代不可變資料結構。

該專案是幫助互動式和並發 C++ 程式變得更容易編寫的長期願景的一部分。透過成為贊助人或購買贊助套餐來幫助該專案的長期可持續性： [email protected]

嘗試一下

如果您使用 Nix 套件管理器（我們強烈推薦它），您只需安裝該軟體即可。

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

發展

要建立程式碼，您需要 C++17 編譯器、 cmake和支援 unicode 的ncurses （Debian 及其朋友中的軟體包libncursesw5-dev ）。

您可以手動安裝它們，但啟動並運行開發環境的最簡單方法是使用 Nix 套件管理器。在儲存庫的根目錄中只需鍵入：

    nix-shell

這將下載所有必需的依賴項並建立一個隔離的環境，您可以在其中使用這些依賴項，而不會污染您的系統。

然後就可以使用CMake生成開發專案了。

    mkdir build && cd build
    cmake ..

若要配置最佳化的建置和編譯，請執行以下操作：

    cmake .. -DCMAKE_BUILD_TYPE=Release
    make

全域安裝已編譯的軟體：

    sudo make install

鍵綁定

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 " },
});
