manage 0.1.15.dev0

1. Using a custom click_commands module (single file)

Lets say you have a commands module in your application, you write your custom command there and manage will load it

# myproject/commands.py
import click
@click.command()
@click.option('--name')
@click.option('--passwd')
def create_user(name, passwd):
    """Create a new user"""
    click.echo('Creating the user...')
    mysystem.User.create(name, password)

Now you go to your manage.yml or .manage.yml and specify your custom command module.

click_commands:
  - module: commands

Now you run manage –help

$ manage --help
...
Commands:
  create_user  Create a new user
  debug        Shows the parsed manage file
  init         Initialize a manage shell in current...
  shell        Runs a Python shell with context

Using a click_commands package (multiple files)

It is common to have different files to hold your commands so you may prefer having a commands/ package and some python modules inside it to hold commands.

# myproject/commands/user.py
import click
@click.command()
@click.option('--name')
@click.option('--passwd')
def create_user(name, passwd):
    """Create a new user"""
    click.echo('Creating the user...')
    mysystem.User.create(name, password)

# myproject/commands/system.py
import click
@click.command()
def clear_cache():
    """Clear the system cache"""
    click.echo('The cache will be erased...')
    mysystem.cache.clear()

So now you want to add all those commands to your manage editing your manage file with.

click_commands:
  - module: commands

Now you run manage –help and you have commands from both modules

$ manage --help
...
Commands:
  create_user  Create a new user
  clear_cache  Clear the system cache
  debug        Shows the parsed manage file
  init         Initialize a manage shell in current...
  shell        Runs a Python shell with context

Custom click_command names

Sometimes the name of commands differ from the name of the function so you can customize it.

click_commands:
  - module: commands.system
    config:
      clear_cache:
        name: reset_cache
        help_text: This resets the cache
  - module: commands.user
    config:
      create_user:
        name: new_user
        help_text: This creates new user

Having different namespaces

If customizing the name looks too much work for you, and you are only trying to handle naming conflicts you can user namespaced commands.

namespaced: true
click_commands:
  - module: commands

Now you run manage –help and you can see all the commands in the same module will be namespaced by modulename_

$ manage --help
...
Commands:
  user_create_user    Create a new user
  system_clear_cache  Clear the system cache
  debug        Shows the parsed manage file
  init         Initialize a manage shell in current...
  shell        Runs a Python shell with context

And you can even customize namespace for each module separately

click_commands:
  - module: commands.system
    namespace: sys
  - module: commands.user
    namespace: user

Now you run manage –help and you can see all the commands in the same module will be namespaced.

$ manage --help
...
Commands:
  user_create_user  Create a new user
  sys_clear_cache  Clear the system cache
  debug        Shows the parsed manage file
  init         Initialize a manage shell in current...
  shell        Runs a Python shell with context

2. Defining your inline commands in manage file directly

Sometimes your command is so simple that you do not want (or can’t) have a custom module, so you can put all your commands in yaml file directly.

inline_commands:
  - name: clear_cache
    help_text: Executes inline code to clear the cache
    context:
      - sys
      - pprint
    options:
      --days:
        default: 100
    code: |
      pprint.pprint({'clean_days': days, 'path': sys.path})

Now running manage –help

$ manage --help
...
Commands:
  clear_cache  Executes inline code to clear the cache
  debug        Shows the parsed manage file
  init         Initialize a manage shell in current...
  shell        Runs a Python shell with context

And you can run using

$ manage clear_cache --days 15

3. Using general functions as commands

And if you already has some defined function (any callable works).

# my_system.functions.py
def create_user(name, password):
    print("Creating user %s" % name)

function_commands:
  - function: my_system.functions.create_user
    name: new_user
    help_text: Create new user
    options:
      --name:
        required: true
      --password:
        required: true

Now running manage –help

$ manage --help
...
Commands:
  new_user     Create new user
  debug        Shows the parsed manage file
  init         Initialize a manage shell in current...
  shell        Runs a Python shell with context

$ manage new_user --name=Bruno --password=1234
Creating user Bruno
