yttc - YANG to TOSCA converter

Library for converts YANG modules into TOSCA node types for Cloudify orchestration framework. Cloudify

YANG - A Data Modeling Language for the Network Configuration Protocol RFC 6020

TOSCA - Topology and Orchestration Specification for Cloud Applications TOSCA

Installation

This module require Python 2.

$git clone https://github.com/cloudify-cosmo/yttc
$cd yttc
$ pip install .

Usage

For converting yang modules, you must call:

yacc.convert(filenames, out_fd)

Where:

• filenames - list of filenames, of yang files
• out_fd - file descriptor. It may be descriptor of open file, or StringIO class.

The output will be written to the out_fd.

Examples:

With StringIO

> import yttc
> import StringIO
> output = StringIO.StringIO()
> yttc.convert( ['acme.yang', 'acme-augment.yang'], output)
> print output.getvalue()
> output.close()

With standart output

> import yttc
> import sys
> output = sys.stdout
> yttc.convert( ['acme.yang', 'acme-augment.yang'], output)

With file

> import yttc
> import sys
> output = file.open('acme.yaml', 'w')
> yttc.convert( ['acme.yang', 'acme-augment.yang'], output)

Testing

Directory examples contains simple YANG files for testing purpose.

For running converter from commad line you can use "test.py" from 'tests' directory:

cd test
python test.py ../examples/acme.yang

Using converter in command line

This library has simple wrapper for pyang command line utility: yttc

pyang is a YANG validator, transformator and code generator, written in python. It can be used to validate YANG modules for correctness, to transform YANG modules into other formats, and to generate code from the modules. https://github.com/mbj4668/pyang

Instead of run: pyang --plugindir /home/user/yttc/plugin -f tosca acme.yang

You can just run: yttc acme.yang

Also you can use other options, that pyang support. For example: yttc -o acme.yaml acme.yang
