invoke travis-ci python

Simple Python task execution

Invoke is a Python (2.6+ and 3.3+) task execution tool & library, drawing inspiration from various sources to arrive at a powerful & clean feature set.

  • Like Ruby’s Rake tool and Invoke’s own predecessor Fabric 1.x, it provides a clean, high level API for running shell commands and defining/organizing task functions from a file:

.. code-block:: python

from invoke import task

def clean(ctx, docs=False, bytecode=False, extra=''):
    patterns = ['build']
    if docs:
    if bytecode:
    if extra:
    for pattern in patterns:"rm -rf %s" % pattern)

def build(ctx, docs=False):"python build")
    if docs:"sphinx-build docs docs/_build")
  • From GNU Make, it inherits an emphasis on minimal boilerplate for common patterns and the ability to run multiple tasks in a single invocation::

    $ invoke clean build

  • Following the lead of most Unix CLI applications, it offers a traditional flag-based style of command-line parsing, deriving flag names and value types from task signatures (optionally, of course!)::

    $ invoke clean –docs –bytecode build –docs –extra=’/*.pyo’ $ invoke clean -d -b build –docs -e ‘/*.pyo’ $ invoke clean -db build -de ‘*/.pyo’

  • Like many of its predecessors, it offers advanced features as well – namespacing, task aliasing, before/after hooks, parallel execution and more.

For documentation, including detailed installation information, please see Post-install usage information may be found in invoke --help.

You can install the development version <>_ via pip install invoke==dev --allow-unverified invoke.
