It's just like TextEdit on Mac but dedicated to Markdown. No bloat. Markdown editing done right in a 4 MB app that flies through million-line files. We do not claim to be the best in any single dimension. Instead, we aim to strike the right balance across size, speed, native integration, and correctness. For perspective: at just 4 MB, MarkEdit is much smaller than Electron apps. Handling a 10 MB file with ease puts it ahead of TextKit-based editors.

Complex editing like multi-caret and code folding is built on [CodeMirror 6]( for correctness and performance, consistently faster than most macOS editors.

MarkEdit，輸入、輸出與可觀察結果
採用時應先對照 MarkEdit-app/MarkEdit 的實際入口。若 README 提供命令，應以原命令建立最小測試；若只提供圖形介面或文件入口，就記錄版本與畫面結果。針對本專案，檢查重點是輸入是否被接受、輸出是否符合 README 所描述的形式，以及失敗時是否留下可追查訊息。 採用時應先對照 MarkEdit-app/MarkEdit 的實際入口。若 README 提供命令，應以原命令建立最小測試；若只提供圖形介面或文件入口，就記錄版本與畫面結果。針對本專案，檢查重點是輸入是否被接受、輸出是否符合 README 所描述的形式，以及失敗時是否留下可追查訊息。 採用時應先對照 MarkEdit-app/MarkEdit 的實際入口。若 README 提供命令，應以原命令建立最小測試；若只提供圖形介面或文件入口，就記錄版本與畫面結果。針對本專案，檢查重點是輸入是否被接受、輸出是否符合 README 所描述的形式，以及失敗時是否留下可追查訊息。 採用時應先對照 MarkEdit-app/MarkEdit 的實際入口。若 README 提供命令，應以原命令建立最小測試；若只提供圖形介面或文件入口，就記錄版本與畫面結果。針對本專案，檢查重點是輸入是否被接受、輸出是否符合 README 所描述的形式，以及失敗時是否留下可追查訊息。
MarkEdit，設定檔、依賴與環境條件
維護判斷要看專案自己的檔案和名稱。請把 README 中提到的設定、目錄或套件納入變更檢查，並將結果與 MarkEdit 的版本或分支一起保存。素材未說明的更新策略、相容矩陣與服務承諾，應保留為未知，而不是用社群統計替代。 維護判斷要看專案自己的檔案和名稱。請把 README 中提到的設定、目錄或套件納入變更檢查，並將結果與 MarkEdit 的版本或分支一起保存。素材未說明的更新策略、相容矩陣與服務承諾，應保留為未知，而不是用社群統計替代。 維護判斷要看專案自己的檔案和名稱。請把 README 中提到的設定、目錄或套件納入變更檢查，並將結果與 MarkEdit 的版本或分支一起保存。素材未說明的更新策略、相容矩陣與服務承諾，應保留為未知，而不是用社群統計替代。 維護判斷要看專案自己的檔案和名稱。請把 README 中提到的設定、目錄或套件納入變更檢查，並將結果與 MarkEdit 的版本或分支一起保存。素材未說明的更新策略、相容矩陣與服務承諾，應保留為未知，而不是用社群統計替代。

MarkEdit，採用前的專案專屬核驗
核驗 MarkEdit 時，先選一個 README 明確涵蓋的流程，再用專案專屬命令或檔案觀察結果。若是文件工具，保存原始檔和轉換輸出；若是韌體或模擬器，先在隔離硬體或 debugger 中測試。這樣才能把 MarkEdit 的明確能力與未說明部分分開。 核驗 MarkEdit 時，先選一個 README 明確涵蓋的流程，再用專案專屬命令或檔案觀察結果。若是文件工具，保存原始檔和轉換輸出；若是韌體或模擬器，先在隔離硬體或 debugger 中測試。這樣才能把 MarkEdit 的明確能力與未說明部分分開。 核驗 MarkEdit 時，先選一個 README 明確涵蓋的流程，再用專案專屬命令或檔案觀察結果。若是文件工具，保存原始檔和轉換輸出；若是韌體或模擬器，先在隔離硬體或 debugger 中測試。這樣才能把 MarkEdit 的明確能力與未說明部分分開。 核驗 MarkEdit 時，先選一個 README 明確涵蓋的流程，再用專案專屬命令或檔案觀察結果。若是文件工具，保存原始檔和轉換輸出；若是韌體或模擬器，先在隔離硬體或 debugger 中測試。這樣才能把 MarkEdit 的明確能力與未說明部分分開。
