idf.py extensions

Python modules (subdirectories and files) in this directory named [your_extension]_ext will be loaded as idf.py extensions. If you want to provide extra extensions just provide ; separated list of directories with extensions in IDF_EXTRA_ACTIONS_PATH. Extensions will be loaded in alphanumeric order. Command line arguments parsing and extension mechanism is implemented on top of Click (versions >=5.0 are supported).

They should define a function action_extensions(base_actions, project_path) where:

• base_actions - dictionary with actions that are already available for idf.py
• project_path - working dir, may be defaulted to os.getcwd()

This function have to return a dict with 3 possible keys:

{
    # Additional options that will be available from id
    "global_options": [{
        "names": ["--option-name"],
        "help": "Help for option --option-name.",
    }],
    # List of functions that will have access to full app context, and can mangle with arguments
    "global_action_callbacks": [global_callback],
    # Additional subcommands for idf.py
    "actions": {
        "subcommand_name": {
            "callback": subcommand_callback,
            "help": "Help for subcommand.",
        },
    },
}

Where function global_callback(ctx, global_args, tasks) accepts 3 arguments:

• ctx - Click context
• global_args - dictionary of all available global arguments
• tasks - list of Task objects

And subcommand_callback(subcommand_name, ctx, args) accepts 3 arguments:

• subcommand_name - name of subcommand
• ctx - Click context
• args - list of command's arguments
