This command can be used to transform a local Container using a given Container transformer.

Currently Available Official Transformers

    pbxproj Can be used to patch one or more pbxproj (iOS project file) included in the Container, in specific ways.
    build-config Can be used to update Build Configuration(s) -build settings- of a generated iOS Container.
    script This transformer allows for executing an arbitrary script to transform the Container in some custom way. It supports transformation of both iOS and Android Containers.
    git-patch Can be used to apply one or more sequential git patches to the Container.


ern transformer-container
    The local file system path to the directory containing the Container to transform.
    Default If this option is not provided, the command will look for a Container in the default platform directory ~/.ern/containergen/out/[platform].=
    Specify the native platform of the target Container to transform.
    This option is required, there is no default (unless --descriptor is used)
    Specify the Container transformer to use (for ex build-config).
    Can also include a specific version or a version range (for ex [email protected] or [email protected]^1.0.0)
    If no version is specified, the latest available version of the publisher will be used at the time of publication (this is a bit risky given that new major publisher versions will contain breaking changes. We recommend that you use a specific version or version range allowing minor and patch updates only)
    It is also possible to pass a local file system path to a Container transformer package (only used for transformers development).
    This option is required, there is no default (unless --descriptor is used)
    Extra configuration specific to the transformer (as json)
    Some transformers might not need any extra configuration. Check the specific Container transformer documentation for reference.
    There is three different ways to provide the json extra configuration :
      As a json string
      For example --extra '{"configKey": "configValue"}'
      As a file path
      For example --extra <path>/transformer-config.json
      In that case, the configuration will be read from the file
      As a Cauldron file path
      For example --extra cauldron://config/publishers/transformer-config.json
      In that case, the configuration will be read from the file stored in Cauldron.
      For this way to work, the file must exist in Cauldron (you can add a file to the cauldron by using the ern cauldron add file command).
ern create-container | Create a new Container (native or JavaScript only) locally to the workstation. ern publish-container | Publish a Container.
