ClickYaml reads a `.yaml` file and creates click Commands out of it.

* Documentation: https://clickyaml.readthedocs.io.

Installation
------------
To install clickYaml, run this command in your terminal:

.. code-block:: bash

    pip install clickyaml

Usage
--------

Input ``yaml`` file example:

.. code-block:: yaml

    simplecommand:
        script: "/home/user/scripts/simplecommand.bash"
        params:
            - !arg
                param_decls: [argument]
            - !opt
                param_decls: ["--option"]

    complexcommand:
        script: "/home/user/scripts/complexcommand.bash"
        help: "Complex Command"
        params:
            - !arg
                param_decls: [id]
            - !arg
                param_decls: [type]
            - !arg
                param_decls: [category]
                type: !obj
                    class: click.Choice
                    choices: ["1","2","3","ALL"]
                    case_sensitive: False
            - !opt
                param_decls: ["--email","-E"]
                multiple: True
                envvar: MY_EMAIL
                help: "Specify the mailing list with this option"

**Note**: There are certain rules on the structure of the yaml file:

- Each command block needs to have blocks for each *parameter* of the command that you define. To know the available parameters refer to the `click documentation <https://click.palletsprojects.com/en/8.1.x/api/#click.Command>`_
- Apart from parameters to click.Command a *script* block can also be used. Script represents a script that you want to link with your command.
- There are three types of tags that can be used in the yaml file: `!obj`, `!arg` and `!opt`
- **!obj** can be used to create custom objects
- **!arg** can be used to create ``click.Argument`` objects
- **!opt** can be used to create ``click.Option`` objects

There are two ways to get the commands from yaml data as **click.Command** objects:

1. Using get_command()
2. Using get_commands()

Get specific commands from the yaml file
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: python

    from clickyaml import get_command, parse_yaml

    parsed_yaml = parse_yaml(path=path_to_yaml)

    # this command has a default callback that runs the script associated with the command
    command_default = get_command(name="simplecommand",parsed_yaml=parsed_yaml,)

    #this command has custom callback that prints the passed arguments
    cstm_clbk = lambda **kwargs: print(kwargs)
    command_custom = get_command(name="simplecommand",parsed_yaml=parsed_yaml,callback=cstm_clbk)

Get all the commands yaml file in a dictionary
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

*all the commands will be assigned the default callback*

.. code-block:: python

    from clickyaml import get_commands

    commands = get_commands(yaml=yaml_data) # returns all the commands in a dictionary

    simplecommand = Commands["simplecommand"]
    complexcommand = Commands["complexcommand"]
