SageFs

概述

SageFs 是一个基于守护程序的 F# 开发工具，通过实时评估、内联结果、测试标记和热重载提供亚秒级代码变更反馈。它通过 MCP 服务器为 AI 代理提供状态机工具，支持 F# 代码执行、类型检查、测试验证和失败解释。多个编辑器和 AI 代理可以同时连接，共享相同的实时会话状态。

FAQ

SageFs 与 Ionide 有什么区别？

Ionide 通过 F# 编译器服务提供智能感知和诊断。SageFs 添加了实时执行功能：评估表达式、查看内联结果、连续测试反馈和热重载。

我可以同时使用 REPL 和 Live 模式吗？

是的，SageFs 支持两种模式。REPL 模式允许完全的类型重定义，而 Live 模式启用浏览器热重载。您可以根据需要切换它们。
