Script Container Transformer

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.

Inputs

• containerPath : Path to the Container to transform
• scriptPath : Path to the script to execute. It can be a local file path (for ex /Users/username/scripts/myscript.sh) or a path to a file stored in the Cauldron (for ex cauldron://scripts/myscript.sh). It is recommended to use the path to a file stored in the CauldronFor the scriptPath (the file needs to be added first to the cauldron through the cauldron add file command).
• scriptParams: Optional parameter(s) to pass on the command line when invoking the script.

Notes

The script will be executed from the Container directory.

Usage

With ern transform-container CLI command

$ ern transform-container --containerPath [pathToContainer] -t script -e '{"scriptPath":"[pathToScript]"}'

Instead of passing the whole configuration on the command line for --extra/-e, it is also possible to use a file path to a json file holding the configuration, or a path to a file stored in the Cauldron. Check out the ern transform-container command documentation for more info.

With Cauldron

To automatically transform the Cauldron generated Containers of a target native application and platform, you can add a transformer entry in the Cauldron in the Container generator configuration object as follow :

Electrode Native <= 0.31

"transformers": [
  {
    "name": "script",
    "extra": {
      "scriptPath": "[pathToScript]",
      "scriptParams": "[params]"
    }
  }
]

Electrode Native >= 0.32

"pipeline": [
  {
    "name": "script",
    "extra": {
      "scriptPath": "[pathToScript]",
      "scriptParams": "[params]"
    }
  }
]

Programmatically

import ScriptTransformer from 'ern-container-transformer-script'
const transformer = new ScriptTransformer()
transformer.transform(
  {
    /* Local file system path to the Container */
    containerPath: string
    /* Extra data specific to this publisher */
    extra?: {
      scriptPath: string,
      scriptParams?: string
    }
  }
})
