## 📲 Install

### 🍺 Homebrew

[Homebrew](http://brew.sh) is the preferred way to install:

```bash
brew install mas
```

⚠️ Note that macOS 10.13 (High Sierra) is required to install mas from the core Homebrew formula.

### ☎️ Older macOS Versions

We provide a [custom Homebrew tap](https://github.com/mas-cli/homebrew-tap) with pre-built bottles
for all macOS versions since 10.11.

To install mas from our tap:

```bash
brew install mas-cli/tap/mas
```

#### Known Installation Issues On macOS Before 10.14.4

Starting with [mas 2.0.0](https://github.com/mas-cli/mas/releases/tag/v2.0.0), if you get
an error similar to `dyld: Symbol not found: _$s11SubSequenceSlTl` when running mas,
you'll need to install the [Swift 5 Runtime Support for Command Line Tools](https://support.apple.com/kb/DL1998).

Alternatively, you can:

- Update to macOS 10.14.4 or later
- Install Xcode 10.2 or later at `/Applications/Xcode.app`
- Rebuild mas from source using Xcode 10.0 or later

### 🐙 GitHub Releases

Alternatively, binaries are available in the [GitHub Releases](https://github.com/mas-cli/mas/releases)

## 🤳🏻 Usage

Each application in the Mac App Store has a product identifier which is also
used for mas-cli commands. Using `mas list` will show all installed
applications and their product identifiers.

```bash
$ mas list
446107677 Screens
407963104 Pixelmator
497799835 Xcode
```

It is possible to search for applications by name using `mas search` which
will search the Mac App Store and return matching identifiers.
Include the `--price` flag to include prices in the result.

```bash
$ mas search Xcode
497799835 Xcode
688199928 Docs for Xcode
449589707 Dash 3 - API Docs & Snippets. Integrates with Xcode, Alfred, TextWrangler and many more.
[...]
```

To install or update an application simply run `mas install` with an
application identifier:

```bash
$ mas install 808809998
==> Downloading PaintCode 2
==> Installed PaintCode 2
```

If you want to install the first result that the `search` command returns, use the `lucky` command.

```bash
$ mas lucky twitter
==> Downloading Twitter
==> Installed Twitter
```

> Please note that this command will not allow you to install (or even purchase) an app for the first time:
it must already be in the Purchased tab of the App Store.

Use `mas outdated` to list all applications with pending updates.

```bash
$ mas outdated
497799835 Xcode (7.0)
446107677 Screens VNC - Access Your Computer From Anywhere (3.6.7)
```

> `mas` is only able to install/update applications that are listed in the Mac App Store itself.
Use [`softwareupdate(8)`] utility for downloading system updates (like iTunes, Xcode Command Line Tools, etc)

To install all pending updates run `mas upgrade`.

```bash
$ mas upgrade
Upgrading 2 outdated applications:
Xcode (7.0), Screens VNC - Access Your Computer From Anywhere (3.6.7)
==> Downloading Xcode
==> Installed Xcode
==> Downloading iFlicks
==> Installed iFlicks
```

Updates can be performed selectively by providing the app identifier(s) to
`mas upgrade`

```bash
$ mas upgrade 715768417
Upgrading 1 outdated application:
Xcode (8.0)
==> Downloading Xcode
==> Installed Xcode
```

### 🚏📥 Sign-in

To sign into the Mac App Store for the first time run `mas signin`.

```bash
$ mas signin mas@example.com
==> Signing in to Apple ID: mas@example.com
Password:
```

> ⚠️ Due to breaking changes in the underlying API that mas uses to interact with the Mac App Store,
> the `signin` command has been temporarily disabled on macOS 10.13+ ⛔.
> For more information on this issue, see [#164](https://github.com/mas-cli/mas/issues/164).

If you experience issues signing in this way, you can ask to signin using a graphical dialog (provided by Mac App Store application):

```bash
$ mas signin --dialog mas@example.com
==> Signing in to Apple ID: mas@example.com
```

You can also embed your password in the command.

```bash
$ mas signin mas@example.com 'ZdkM4f$gzF;gX3ABXNLf8KcCt.x.np'
==> Signing in to Apple ID: mas@example.com
```

Use `mas signout` to sign out from the Mac App Store.

## 🍺 Homebrew integration

`mas` is integrated with [homebrew-bundle]. If `mas` is installed, and you run `brew bundle dump`,
then your Mac App Store apps will be included in the Brewfile created. See the [homebrew-bundle]
docs for more details.

## 💥 When something doesn't work

If you see the error "This redownload is not available for this Apple ID either because it was bought by a different user of the item was refunded or cancelled.", it's probably because you haven't installed the app through the App Store yet. See [#46](https://github.com/mas-cli/mas/issues/46#issuecomment-248581233).

If `mas` doesn't work for you as expected (e.g. you can't update/download apps), run `mas reset` and try again. If the issue persists, please [file a bug](https://github.com/mas-cli/mas/issues/new)! All your feedback is much appreciated ✨

## 📺 Using `tmux`

`mas` operates via the same system services as the Mac App Store. These exist as
separate processes with communication through XPC. As a result of this, `mas`
experiences similar problems as the pasteboard when running inside `tmux`. A
[wrapper tool exists](https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard) to
fix pasteboard behaviour which also works for `mas`.

You should consider configuring `tmux` to use the wrapper but if you do not wish
to do this it can be used on a one-off basis as follows:

```bash
brew install reattach-to-user-namespace
reattach-to-user-namespace mas install
```

## ℹ️ Build from source

You can now build from Xcode by opening `mas-cli.xcodeproj`, or from the Terminal:

```bash
script/build
```

Build output can be found in the `build/` directory within the project.

## ✅ Tests

The tests in this project are a recent work-in-progress.
Since Xcode does not officially support tests for command-line tool targets,
all logic is part of the MasKit target with tests in MasKitTests.
Tests are written using [Quick].
