Giammarco-Ferranti/deja：README 來源編輯指南

Giammarco-Ferranti/deja 的 README 將專案描述為「Predictive inline shell autosuggestions for zsh. Go daemon, no TUI, no sync」。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：Deja is a smarter replacement for zsh-autosuggestions. Instead of only surfacing commands that start with what you've typed, Deja uses fuzzy matching, directory awareness, and command sequence prediction to suggest what you actually want。這說明的是專案邊界，不是已完成的生產驗證。

從 README 的「Features」與相關條目，可以先判斷它是否處理你的實際問題：Directory awareness , commands you run in /projects/foo rank higher when you're in /projects/foo。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：Fuzzy matching , suggests commands even when you skip letters or mix up order。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「curl (any Linux/macOS, no Homebrew required)」等段落。可確認的線索包括：Both commands install deja, import your existing zsh history, add the integration to /.zshrc (idempotent), and reload your shell. To audit the curl installer before running it, view it on GitHub.。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： brew install Giammarco-Ferranti/deja/deja && deja import && (grep -qF 'deja init zsh' ~/.zshrc 2>/dev/null || echo 'eval "$(deja init zsh)"' >> ~/.zshrc) && exec zsh 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「Installation」，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「Oh My Zsh」段落提到：If you manage zsh with Oh My Zsh, enable deja the idiomatic way, the same flow as zsh-autosuggestions. The binary still comes from Homebrew or the curl script; the plugin just sources deja's integration for you.。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：Sequence prediction , knows that you usually run make test after make build。
