jaseci-labs/jac：README 來源編輯指南

jaseci-labs/jac 的 README 將專案描述為「The Jac Programming Language -- the only language you need to build anything (full stack app, device driver, video game, website, whatever). One self-contained binary; One language;」。本文只整理倉庫可直接核對的內容，不把 star、Fork 或宣傳語當成品質證明。README 在「README」下寫到：Jac is a programming language designed for humans and AI to build together. It compiles one clean, Python-like syntax to Python bytecode, JavaScript, and native machine code, with the entire PyPI, npm, and C ecosystems available without。這說明的是專案邊界，不是已完成的生產驗證。

從 README 的「README」與相關條目，可以先判斷它是否處理你的實際問題：One language for the whole stack, compiler-checked end to end -- frontend, backend, and data model are one program under one type checker: humans and AI write correct code faster, and there is one codebase to maintain, not five。若需求不同，不應只因專案熱度就採用。本文保留原始專案名、命令與元件名，方便回到一手來源核對。 README 另外列出一項可核對的資訊：One binary, your whole toolchain -- one download replaces the python interpreter, the JS runtime, the Rust/Zig/C compilers, and the package managers: nothing else to install。這類原文條目可用來設計試跑步驟，但不能取代實際環境測試。

README 將運作方式分散在「Try Jac in 30 seconds」等段落。可確認的線索包括：Install the self-contained jac binary. No Python, pip, Node, or C toolchain required:。本文不把未寫出的架構、效能或安全邊界補成結論；真正的執行鏈仍要配合目錄、設定檔與版本標籤檢查。

第一次安裝應從 README 指出的入口開始。目前可核對的命令是： curl -fsSL https://raw.githubusercontent.com/jaseci-labs/jaseci/main/scripts/install.sh | bash 如果倉庫沒有命令，本文不會自行編造步驟，而是建議先閱讀「Why Jac exists」，確認系統依賴、預設埠與首次初始化。

日常使用取決於專案文件。README 的「Try Jac in 30 seconds」段落提到：One language spans all three codespaces in this single codebase: the pages and components compile to JavaScript, the endpoints compile to Python and serve over RPC, and the arcade game in game/arena.jac compiles through LLVM to in-browser。設定檔、環境變數、權限與資料目錄只在來源明確時才會記錄；沒有寫出的預設值，應在測試環境驗證並保留回滾副本。 同一部分也提到：5x less code than a modern full-stack setup -- the difference is glue the compiler now generates: API endpoints, route tables, ORM models, validation, serializers, and migrations you never write, review, or debug。
