Autogenerate completions for CLI tools built with cement

Project description

Autogenerate Completions for CLI tools built with cement

This package generates Fig completions for CLI tools built on Cement.


Install the integration as a dependency using pip:

pip install cement_complete_fig


Choose one of the methods below to add the generate-fig-spec subcommand to the top level of your CLI tool.

Method 1: Load as a Cement extension

This package provides a Cement extension for convenience called 'cement_complete_fig.ext.ext_complete_fig' which can be loaded in any of the ways cited in the linked documentation.

Repeated here for convenience you can do one of the following:

  1. Add the extension to the Meta of your App object:
from cement import App

class MyApp(App):
    class Meta:
        label = 'myapp'
        extensions = [
  1. Manually load the extension before running your app:
from cement import App

with App('myapp') as app:
  1. Add the extension to your app configuration file (e.g. .myapp.conf):
exensions = cement_complete_fig.ext.ext_complete_fig

Method 2: Bind the controller manually

You can also add the GenerateFigSpecController manually as a handler to your app:

from cement import App
from cement_complete_fig import GenerateFigSpecController

class MyApp(App):
    class Meta:
        label = 'myapp'
        handlers = [

with MyApp() as app:

Generating the spec file

Once you've added the integration you will have new subcommand nested under your base handler. When this subcommand is invoked it will print a Fig spec.

To save your completion spec skeleton to a file, run the following:

myapp generate-fig-spec > myapp.ts
