@guneriu/pi-files

Shows the files the agent edited this session in a compact widget above the input bar, and opens an interactive, gitignore-aware project tree on demand.

Features

• Compact widget above the editor: + new / M modified, capped rows with … +N more overflow so a big change set never swamps the terminal.
• Idle hint when nothing is edited yet (toggle off in settings).
• /pi-files — full-screen tree overlay with keyboard navigation; auto-expands to your edited files on open.
  • Enter opens the selected file in your OS default app.
  • Space opens a scrollable, syntax-highlighted in-TUI peek (Quick Look style).
  • d (inside peek) toggles between diff view and full-content view for modified files.
  • Type anything to filter all project files instantly — no prefix needed.
• Diff-first peek for modified files — when you peek at a file the agent has edited, the view opens in diff mode by default: red for removed lines, green for added lines, compared against the session baseline (the file contents at session start). Press d to toggle back to the full file view at any time.
• /pi-files-settings — interactive settings menu to toggle the widget, collapse it for the session, adjust the row cap, set the peek size limit, and more.
• Respects .gitignore via git ls-files; falls back to a filesystem walk outside git repos.

Commands & shortcuts

Slash commands

| Command | Description | |---|---| | /pi-files | Open the interactive project tree overlay | | /pi-files-settings | Open the settings menu |

Inside the project tree (/pi-files)

| Key | Action | |---|---| | ↑ / ↓ | Move selection | | Enter | Open file in OS default app — expands a directory | | Space | Peek — in-TUI syntax-highlighted preview (toggle: same key closes) | | d | Inside peek: toggle diff view ↔ full-content view | | → | Expand a directory | | ← | Collapse a directory — or jump to its parent if already collapsed | | Esc | Close the overlay (clears filter first if one is active) | | any printable char | Filter — type to search all project files instantly | | Backspace | Remove last filter character; empty filter returns to tree view |

Type-to-filter search

Start typing anywhere in the tree — no prefix key needed. The view switches to a flat filtered list of all project files (including inside collapsed directories) whose path contains your query (case-insensitive).

• The header shows / query▌ N results esc clear while filtering.
• Matched portion of each path is highlighted.
• ↑/↓, Enter, and Space (peek) all work on filter results.
• Esc clears the filter and returns to the tree. Esc again closes the overlay.
• Backspace removes one character at a time; empties = back to tree.
• → / ← expand/collapse are inactive while filtering.

Opening files

• Enter launches the file with your OS default application (open on macOS, xdg-open on Linux, start on Windows). On a headless/SSH box with no GUI handler you'll get a notification instead.
• Space opens a scrollable, syntax-highlighted preview inside pi — no need to leave the terminal. Press Space again (or Esc/q) to close.
  • Scroll with ↑/↓, page with PgUp/PgDn, jump to top/bottom with g/G.
  • Markdown files get structural highlighting (headings, code blocks, lists, links) via a built-in pure ANSI renderer — no extra tools required.
  • Files larger than Max peek size (default 512 KB) are refused with a hint to open them externally instead.
  • Binary files are detected and refused (open them externally).

Diff view (modified files)

When you peek at a file the agent has modified this session, the peek opens in diff mode by default — red lines for what was removed, green for what was added, compared against the session baseline (the file content at session start, or the last committed version if the session baseline isn't available).

• The hint bar shows [diff·git] +N −N d content ↑↓ g/G spc close.
• Press d to switch to the full file view; press d again to return to diff.
• If no baseline is available (new file, or identical content), diff mode is skipped and pi notifies you that no diff is available.
• New (untracked) files always open in content mode.

Inside the settings menu (/pi-files-settings)

| Key | Action | |---|---| | ↑ / ↓ | Move between items | | Space or Enter | Toggle a boolean setting | | ← / → | Decrease / increase a number setting | | Esc or q | Close the menu |

Settings

Settings can be changed interactively via /pi-files-settings or by editing <agent-dir>/extensions/pi-files/settings.json directly.

| Key | Default | Meaning | Persists? | |---|---|---|---| | enabled | true | Master on/off for the widget | ✅ yes | | maxWidgetRows | 6 | Max file rows shown in the compact widget | ✅ yes | | showIdleHint | true | Show a one-line hint when no files have been edited yet | ✅ yes | | maxPeekBytes | 524288 | Largest file (bytes) the in-TUI peek will render | ✅ yes |

In the settings menu, Max widget rows is adjusted with ←/→ (range 1–20) and Max peek size (KB) in 64 KB steps (range 64 KB–8 MB).

Session collapse

The settings menu also offers Collapse this session — a temporary hide that lasts only until you close pi. Unlike enabled, it is never written to disk, so the widget always comes back on the next session start without any manual action.

Use it when you want to free up screen space mid-session without permanently disabling the feature.
