Merge into master from pull request #360: add of_bsn_tlv_reference (https://github.com/floodlight/loxigen/pull/360)
LoxiGen is a tool that generates OpenFlow protocol libraries for a number of languages. It is composed of a frontend that parses wire protocol descriptions and a backend for each supported language (currently C, Python, and Java, with an auto-generated wireshark dissector in Lua on the way).
LoxiGen currently supports OpenFlow Versions 1.0, 1.1, 1.2, and 1.3.1. Versions 1.0 and 1.3.1 are actively used in production. Support for versions 1.1 and 1.2 is considered experimental.
Loxigen is free and open source software. The Loxigen tool itself is licensed under the Eclipse Public License, version 1.0 (EPL), with an exception allowing for the distribution of the generated artifacts under terms of your choice (copyright notices must be retained, see the loxigen.py header for details.)
Running the unit tests requires nosetests. You can install it via easy_install,
easy_install nose
pip,
pip install nose
or via your distribution's package manager (example for Debian/Ubuntu):
sudo apt-get install python-nose
Nosetests is only required for running the unit tests, not for running LoxiGen itself. We do ask you to install it and use it before submitting pull requests, though.
Running the Java unit tests requires Maven 3: sudo apt-get install maven.
You can run LoxiGen directly from the repository. There's no need to install it, and it has no dependencies beyond Python 2.7+.
To generate the libraries for all languages:
make
To generate the library for a single language:
make c
The currently supported languages are c, python and java. There is an experimental/partially completed backend that generates a lua wireshark dissector (wireshark).
The generated libraries will be under the loxi_output directory. This can be changed with the LOXI_OUTPUT_DIR environment variable when using the Makefile.
Each generated library comes with its own set of documentation in the standard format for that language. Please see that documentation for more details on using the generated libraries.
Please fork the repository on GitHub and send us a pull request. You might also be interested in the INTERNALS file which has notes about how LoxiGen works.
Loxigen comes with a set of internal unit-tests, as well as with a set of tests for the generated artifacts. Be sure to run
make check-all
and correct any problems before submitting a pull request.
