`moon` installs a downloaded archive, AppImage or `.deb` in one command. Zero crates, zero daemons, one binary. ( more features in future )

## Install

```sh
cargo install moon
```

No Rust toolchain? The release script does the same thing from the published binaries, into `~/.local/bin`:

```sh
curl -fsSL https://moonpkg.github.io/cli/scripts/install.sh | bash
```

```sh
moon install app-1.2.3-linux-x64.tar.xz
```

It will:

1. <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/FOLDER.svg" width="16" alt="" valign="-3"> extract the archive into `~/.local/share/moon/apps/<name>/`
2. <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/LINK.svg" width="16" alt="" valign="-3"> symlink the executable(s) into `~/.local/bin` so you can run them from a terminal
3. <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/LIST.svg" width="16" alt="" valign="-3"> write `~/.local/share/applications/<name>.desktop`, reusing the package's own `.desktop` file and icon when present
4. <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/REFRESH.svg" width="16" alt="" valign="-3"> run `update-desktop-database` so it shows up in the applications menu
5. <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/SAVE.svg" width="16" alt="" valign="-3"> remember everything in a manifest, so `moon remove` and `moon undo` can put it all back

| <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/MOON.svg" width="16" alt="moon"> | `moon help`, `moon version` | |

Aliases where they feel natural: `ls` for list, `rm` for remove, `i`/`add` for install, `show`/`what` for inspect, `log`/`hist` for history, `check`/`verify`/`repair` for doctor.

### Install options

| option | meaning |
|---|---|
| `--name <name>` | app and command name (default: guessed from the file name) |
| `--bin <rel/path>` | the main executable inside the archive (default: auto-detected) |
| `--desktop` / `--no-desktop` | force or forbid a menu entry |
| `--force` | overwrite entries that moon does not own |
| `--portable-dir <path>` | keep the app on another disk instead of `~/.local` |

Re-running `install` on an installed app shows what changed and asks whether to upgrade, reinstall, keep or inspect first. In a script it just replaces, and says whether that was an upgrade, a reinstall or a downgrade.

Archives without an icon or `.desktop` file are treated as CLI tools: no menu entry unless you pass `--desktop`.

### <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/PACKAGE.svg" width="18" alt="" valign="-4"> `.deb` packages

```
moon install nowly-host.deb --dry-run   # show the plan, write nothing
moon install nowly-host.deb             # install per-user into ~/.local
sudo moon install nowly-host.deb --root # dpkg-style, into the real /usr
```

| option | meaning |
|---|---|
| `--root` | install to the real `/usr`, `/opt`, ... (needs root) |
| `--run-scripts` | run the package's `preinst`/`postinst` (never by default) |
| `--no-rewrite` | don't rewrite absolute paths inside desktop files and wrappers |
| `--dry-run`, `-n` | show what would be installed |

Packages with files outside `/usr` (icons, appdata, desktop files) get relocated under `~/.local/share/moon/apps/<name>/system` and every absolute path inside the package is rewritten to match, so nothing ends up pointing at paths that don't exist. `--root` skips the relocation. Conflicts with files moon doesn't own are refused unless you pass `--force`.

### <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/DRIVE.svg" width="18" alt="" valign="-4"> Portable installs

<img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/DRIVE.svg" width="16" alt="" valign="-4"> Keep an app on a USB stick instead of in `~/.local`:

```
moon install SomeApp.AppImage --portable-dir /mnt/USB/Apps
```

```
USB/
└── Apps/
    └── someapp/
        ├── SomeApp.AppImage
        ├── someapp.desktop
        └── icon.png
```

Command links in `~/.local/bin` and the menu entry still work; they just point into the bundle. Plug the drive into another machine and the app is there.

### <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/SAVE.svg" width="18" alt="" valign="-4"> Exporting a bundle

<img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/SAVE.svg" width="16" alt="" valign="-4"> Turn anything moon already installed into a self-contained folder:

```
moon export someapp                 # creates ./someapp/
moon export someapp /mnt/USB/Apps   # or somewhere else
moon unexport someapp               # delete the bundle
```

The bundle carries the app, its menu entry and its icon, with absolute paths pointing inside the bundle. `moon doctor` flags a portable app whose directory has gone missing, which is what an unplugged USB stick looks like.

### <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/PACKAGE.svg" width="18" alt="" valign="-4"> `.moon` bundles

A `.moon` bundle is one file that holds a whole app: the program, its metadata, its icon and its menu entry. It is a plain `tar.gz`, so `tar xf SomeApp.moon` still works, and there is no server involved on either end.

```
moon bundle someapp        # an installed app  -> ./someapp.moon
moon bundle ytkew-moon     # a bundle folder  -> ./ytkew-moon.moon
moon install someapp.moon  # on any machine, yours included
```

A bundle folder is a `.manifest` plus `app/`, and optionally `desktop/` and `icon/`:

```
ytkew-moon/
├── ytkew.manifest
├── app/
│   └── ytkew
├── desktop/
│   └── ytkew.desktop
└── icon/
    └── ytkew.svg
```

The manifest is moon's own `key=value` format with paths relative to the bundle: `dir`, `main`, `version`, `desktop`, and `link`/`to` pairs for each command. On install moon rewrites the bundled menu entry to the new machine's paths, links the commands into `~/.local/bin`, and saves a manifest with the real ones. **[How to bundle](https://github.com/moonpkg/cli/blob/main/HOW_TO_BUNDLE.md)** has the whole guide.

### <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/WRENCH.svg" width="18" alt="" valign="-4"> doctor

```
moon doctor
```

```
Broken entries:

⚠ someapp 1.2.3
   Application missing: ~/.local/share/moon/apps/someapp
   Menu entry missing: ~/.local/share/applications/someapp.desktop

⚠ btop
   Symlink exists
   Target missing: ~/.local/bin/btop
   Points at: ~/.local/share/moon/apps/btop/bin/btop
```

<img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/WRENCH.svg" width="16" alt="" valign="-4"> `moon doctor --fix` removes the leftovers and updates the manifests. Add `--yes` to skip the question. It also finds command links in `~/.local/bin` that point at nothing and that moon did not create; those are reported but not touched.

## <img src="https://raw.githubusercontent.com/moonpkg/cli/main/docs/icons/MAGIC.svg" width="18" alt="" valign="-4"> Icons

moon uses Nerd Font glyphs when it detects one and plain text when it does not, so the output stays readable either way:

```
moon config --icons auto   # default: icons only if a Nerd Font is installed
moon config --icons always
moon config --icons never
```

All 26 glyphs are single codepoints in the Font Awesome, Octicons and Devicons ranges of [Nerd Fonts](https://www.nerdfonts.com), so any patched Nerd Font covers them.

## Supported inputs

`.tar.gz` `.tar.xz` `.tar.bz2` `.tar.zst` `.tgz` `.tar` `.zip` `.7z` `.AppImage` `.deb` `.moon`, bare executables, and `http(s)://` URLs.

`moon install` with no arguments opens a picker over the current directory: arrows or `hjkl` to move, `enter` to install, `q` to quit.
