Argument passing

Types of arguments

Jackadi supports different ways to pass arguments to tasks:

Positional arguments

Positional arguments are passed in order after the task name:

jack run node1 myplugin.task2 John 30

In this example:

• John is the first positional argument
• 30 is the second positional argument

The task receives these arguments in the order they are provided.

Named options (key-value pairs)

Named arguments use the key=value syntax:

jack run node1 myplugin.task3 name="John" age=30

This passes:

• name with value "John"
• age with value 30

These key-value pairs are passed to the task argument implementing sdk.Option. See more details here.

Mixed arguments

You can combine positional and named arguments:

jack run node1 myplugin.task4 John age=30

This passes:

• John as the first positional argument
• age=30 as a named argument
