3DS CodEdit

3DS CodEdit is a code-first editor and project workspace for Nintendo 3DS. It combines a lightweight multi-tab text editor, project Git workflow, file manager tools, and a monochrome draw mode for quick PBM assets.

What It Focuses On

1. Code editing on-device

• Multi-tab text editor (up to 4 open documents).
• Create, open, edit, save, and save-as files directly on SD.
• Line-based editing with cursor movement, line numbers, and visible cursor position (Ln/Col).
• Fast editing actions from buttons and top menu:
  • edit current line with OSK,
  • insert newline,
  • close/switch tabs,
  • find next text match,
  • undo/redo support.
• Sidebar workflow for project files: open files/folders, create new file/folder, go to parent directory.

2. Integrated Git + GitHub workflow

• Local Git actions:
  • init repository,
  • add all,
  • commit staged changes,
  • staged file counter and branch display.
• GitHub actions:
  • probe remote,
  • clone to current path,
  • fetch,
  • pull (fast-forward),
  • push,
  • personal access token storage.
• .gitignore support in add-all and push file scanning.
• Multi-repository safety improvements:
  • repository-local remote/branch state is preferred,
  • Root* warning when operating from a subfolder,
  • double-confirm guard for root-scope actions.

3. Draw mode for pixel assets (.pbm)

• Built-in black/white canvas editor (stylus pen + eraser).
• Create new drawings from editor sidebar (DRAW).
• Open existing .pbm files from Explorer or editor sidebar.
• Save as PBM (P4) and return to Git workflow for commit/push.

File and System Features

• Explorer with storage usage bar, icons, and multi-select.
• File operations: create, rename, delete, copy, move, and batch operations.
• Archive extraction support (.zip, .rar, .7z, .lzma).
• Image viewer with zoom/pan and image properties.
• Search and quick jump to a path.
• Optional CTRNAND browsing/copying in developer options.
• Sorting modes: alphabetical (asc/desc) and size (largest/smallest).
• Dark theme, updater, and persistent config (last_dir, sort mode, Git defaults, token).

Quick Navigation Notes

• Home icon toggles between Explorer and editor.
• In Explorer, SELECT also returns to editor.
• In editor, SELECT opens/closes the top menu (File, Edit, Search, View, Project).
• Project opens the Git panel.
