Alexey Lapshin 2d61c9ca79 tools: move cmake executable check into function uses it
Before this change idf.py could exit with reason cmake does not exist in PATH
even cmake will not be executed by idf.py (e.g., 'idf.py gdb').

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
