Features / 特性
Pipes: Clean data flow without nesting; things flow from top to bottom. 管道： 清晰的数据流，无需嵌套；数据从上到下流动。
Run errors-as-values: Nil and booleans are replaced by atoms. You can’t use a value without handling an error. All crashes are explicit (WIP). Aided massively by pattern matching, ?, orelse, and :unwrap().
错误即值： Nil 和布尔值被原子（atoms）取代。如果不处理错误，你就无法使用该值。所有崩溃都是显式的（开发中）。得益于模式匹配、?、orelse 和 :unwrap()，处理过程非常顺畅。
Run everything is an expression: No statements; everything (really) always returns a value… but the code still looks procedural. 一切皆表达式： 没有语句；所有东西（真的）总是返回一个值……但代码看起来仍然是过程式的。
Run comp: Execute any (really) expression at compile time. Any script can be compiled into bytecode and get any value baked in. The compile-time VM does not differ from the runtime one. 编译期执行： 在编译时执行任何（真的）表达式。任何脚本都可以编译成字节码并将任何值预先计算进去。编译期虚拟机与运行时虚拟机没有区别。
Run procedural macros: Along with an AST-substituting macro system, this lets you just get an iterator over the raw AST tokens, run any code to transform them, then return back a table of the new AST. 过程宏： 配合 AST 替换宏系统，你可以获取原始 AST 标记的迭代器，运行任何代码进行转换，然后返回一个新的 AST 表。
Run pattern matching: Destructure and branch in place. You will be using atoms and tuples; they are beautiful solutions to their problems. 模式匹配： 原地解构和分支。你将使用原子和元组；它们是解决问题的优雅方案。
Run fibers: I made all your blocking code become non-blocking by just adding a spawn before it.
纤程（Fibers）： 我让所有的阻塞代码只需在前面加上 spawn 即可变为非阻塞。
Run tables: Represent everything; used for module exports, arrays, and maps. 表（Tables）： 代表一切；用于模块导出、数组和映射。
Run convenient typing: The type system is optional, but very well-integrated. Untyped code works just fine, but typed code is faster and gets optimized better (and ensures code correctness at compile-time!). Most of your code is going to be inferred automatically. 便捷的类型系统： 类型系统是可选的，但集成度很高。无类型代码运行良好，但有类型代码更快且优化更好（并确保编译时的代码正确性！）。你大部分的代码都将被自动推断。
Run first-class tests: They’re just closures and they fail when you return an error. The ? postfix operator propagates errors, giving you a pretty simple experience.
一等公民测试： 它们只是闭包，当你返回错误时它们就会失败。? 后缀运算符会传播错误，为你提供非常简单的体验。
Installation / 安装
Get: The latest release is hosted at GitHub releases. However, this project is rapidly changing. I recommend you build from source instead. If a binary release is older than a week, it’s likely that it has some critical bugs that are fixed already. 获取： 最新版本托管在 GitHub Releases。然而，该项目变化迅速，我建议你从源码构建。如果二进制版本超过一周，它很可能存在已经修复的关键 Bug。
Install from source: You need Zig 0.16.0 to build Revo. I also recommend the anyzig version manager.
从源码安装： 你需要 Zig 0.16.0 来构建 Revo。我也推荐使用 anyzig 版本管理器。
Linux/BSD/Mac/etc:
git clone https://github.com/if-not-nil/revo --recursive && cd revo
git submodule update --init --recursive
zig build --fetch
zig build -Doptimize=ReleaseSafe
cp ./zig-out/bin/revo ~/.local/bin/revo
revoWindows: [!NOTE] Some features are unavailable on Windows. I recommend using WSL with the steps above. [!NOTE] 部分功能在 Windows 上不可用。我建议使用 WSL 并按照上述步骤操作。
Tools / 工具
LSP: Diagnostics, highlighting, etc., in your editor! Bundled by default with your Revo. LSP： 编辑器中的诊断、高亮等功能！随 Revo 默认捆绑。
Docs: Output docs in plaintext/html. 文档： 输出纯文本/HTML 格式的文档。
revo doc <file or directory>
revo doc --html <file or directory>Editors: VS Code, Neovim, Helix, Emacs. 编辑器： 支持 VS Code、Neovim、Helix 和 Emacs。
