Settings

Trigger

Output	Description
args	An array of command line arguments

The array contains the command-line flags from os.Args[2:], os.Args[1] is used to determine which flow is called. So a Flogo app with a CLI trigger that is started like:

$ ./cliapp -myflow -param1 foo -param2 bar 

will result in the engine executing the flow where the handler.settings.command field is myflow and pass on the other four arguments in the array args.

Handler:

Setting	Description
command	The command invoked
default	Indicates if its the default command

Map arguments

To use the args array from the trigger you'll need to specify an input parameter of type array and map the args from the trigger to it.

"mappings": {
  "input": [
    {
      "mapTo": "commandline",
      "type": "assign",
      "value": "$.args"
    }
  ]
}
