branch_io_cli gem
This is a command-line tool to integrate the Branch SDK into mobile app projects. (Currently iOS only.)
Preliminary release
This is a preliminary release of this gem. Please report any problems by opening issues in this repo.
Using Fastlane?
See also the Branch Fastlane plugin, which offers the same support via Fastlane.
Getting started
gem install branch_io_cli
Note that this command may require sudo access if you are using the system Ruby, i.e. sudo gem install branch_io_cli.
branch_io -h
branch_io setup -h
branch_io validate -h
Commands
Setup command
branch_io setup
Integrates the Branch SDK into a native app project. This currently supports iOS only.
It will infer the project location if there is exactly one .xcodeproj anywhere under
the current directory, excluding any in a Pods or Carthage folder. Otherwise, specify
the project location using the --xcodeproj option, or the CLI will prompt you for the
location.
If a Podfile or Cartfile is detected, the Branch SDK will be added to the relevant
configuration file and the dependencies updated to include the Branch framework.
This behavior may be suppressed using --no-add-sdk. If no Podfile or Cartfile
is found, and Branch.framework is not already among the project's dependencies,
you will be prompted for a number of choices, including setting up CocoaPods or
Carthage for the project or directly installing the Branch.framework.
By default, all supplied Universal Link domains are validated. If validation passes,
the setup continues. If validation fails, no further action is taken. Suppress
validation using --no-validate or force changes when validation fails using
--force.
By default, this command will look for the first app target in the project. Test
targets are not supported. To set up an extension target, supply the --target option.
All relevant target settings are modified. The Branch keys are added to the Info.plist,
along with the branch_universal_link_domains key for custom domains (when --domains
is used). For app targets, all domains are added to the project's Associated Domains
entitlement. An entitlements file is also added for app targets if none is found.
Optionally, if --frameworks is specified, this command can add a list of system
frameworks to the target's dependencies (e.g., AdSupport, CoreSpotlight, SafariServices).
A language-specific patch is applied to the AppDelegate (Swift or Objective-C).
This can be suppressed using --no-patch-source.
Prerequisites
Before using this command, make sure to set up your app in the Branch Dashboard. See https://docs.branch.io/pages/dashboard/integrate/ for details. To use the setup command, you need:
- Branch key(s), either live, test or both
- Domain name(s) used for Branch links
- Location of your Xcode project (may be inferred in simple projects)
To use the --commit option, you must have the git command available in your path.
To add the SDK with CocoaPods or Carthage, you must have the pod or carthage
command, respectively, available in your path.
Options
| Option | Description |
|---|---|
| -L, --live-key key_live_xxxx | Branch live key |
| -T, --test-key key_test_yyyy | Branch test key |
| --app-link-subdomain myapp | Branch app.link subdomain, e.g. myapp for myapp.app.link |
| -D, --domains example.com,www.example.com | Comma-separated list of custom domain(s) or non-Branch domain(s) |
| -U, --uri-scheme myurischeme[://] | Custom URI scheme used in the Branch Dashboard for this app |
| --xcodeproj MyProject.xcodeproj | Path to an Xcode project to update |
| --target MyAppTarget | Name of a target to modify in the Xcode project |
| --podfile /path/to/Podfile | Path to the Podfile for the project |
| --cartfile /path/to/Cartfile | Path to the Cartfile for the project |
| --frameworks AdSupport,CoreSpotlight,SafariServices | Comma-separated list of system frameworks to add to the project |
| --[no-]pod-repo-update | Update the local podspec repo before installing (default: yes) |
| --[no-]validate | Validate Universal Link configuration (default: yes) |
| --[no-]force | Update project even if Universal Link validation fails (default: no) |
| --[no-]add-sdk | Add the Branch framework to the project (default: yes) |
| --[no-]patch-source | Add Branch SDK calls to the AppDelegate (default: yes) |
| --[no-]commit | Commit the results to Git (default: no) |
All parameters are optional. A live key or test key, or both is required, as well as at least one domain. Specify --live-key, --test-key or both and --app-link-subdomain, --domains or both. If these are not specified, this command will prompt you for the information.
Examples
Test without validation (can use dummy keys and domains)
branch_io setup -L key_live_xxxx -D myapp.app.link --no-validate
Use both live and test keys
branch_io setup -L key_live_xxxx -T key_test_yyyy -D myapp.app.link
Use custom or non-Branch domains
branch_io setup -D myapp.app.link,example.com,www.example.com
Avoid pod repo update
branch_io setup --no-pod-repo-update
Validate command
branch_io validate
This command validates all Universal Link domains configured in a project without making any modification. It validates both Branch and non-Branch domains. Unlike web-based Universal Link validators, this command operates directly on the project. It finds the bundle and signing team identifiers in the project as well as the app's Associated Domains. It requests the apple-app-site-association file for each domain and validates the file against the project's settings.
Only app targets are supported for this command. By default, it will validate the first. If your project has multiple app targets, specify the <%= color('--target', BOLD) %> option to validate other targets.
Options
| Option | Description |
|---|---|
| -D, --domains example.com,www.example.com | Comma-separated list of domains. May include app.link subdomains. |
| --xcodeproj MyProject.xcodeproj | Path to an Xcode project to update |
| --target MyAppTarget | Name of a target to modify in the Xcode project |
All parameters are optional. If --domains is specified, the list of Universal Link domains in the
Associated Domains entitlement must exactly match this list, without regard to order. If no --domains
are provided, validation passes if at least one Universal Link domain is configured and passes validation,
and no Universal Link domain is present that does not pass validation.
Return value
If validation passes, this command returns 0. If validation fails, it returns 1.
Examples
See the examples folder for several example projects that can be used to exercise the CLI.
