Common workflow language tool description reference implementation
==================================================================

CWL Conformance test: |Build Status|

This is the reference implementation of the Common Workflow Language. It is
intended to be feature complete and provide comprehensive validation of CWL
files as well as provide other tools related to working with CWL.

This is written and tested for Python 2.7.

The reference implementation consists of two packages. The "cwltool" package
is the primary Python module containing the reference implementation in the
"cwltool" module and console executable by the same name.

The "cwl-runner" package is optional and provides an additional entry point
under the alias "cwl-runner", which is the implementation-agnostic name for the
default CWL interpreter installed on a host.

Install
-------

Installing the official package from PyPi (will install "cwltool" package as well)::

pip install cwlref-runner

Or from source::

git clone https://github.com/common-workflow-language/cwltool.git
cd cwltool && python setup.py install
cd cwlref-runner && python setup.py install

Run on the command line
-----------------------

Simple command::

cwl-runner [tool] [job]

Import as a module
----------------

Add::

import cwltool

to your script.

Use with boot2docker
--------------------
boot2docker is running docker inside a virtual machine and it only mounts ``Users``
on it. The default behavoir of CWL is to create temporary directories under e.g.
``/Var`` which is not accessible to Docker containers.

To run CWL successfully with boot2docker you need to set the ``--tmpdir-prefix``
and ``--tmp-outdir-prefix`` to somewhere under ``/Users``::

$ cwl-runner --tmp-outdir-prefix=/Users/username/project --tmpdir-prefix=/Users/username/project wc-tool.cwl wc-job.json
