Yangre-gui is the idea of Benoit Claise and was built by myself for the IETF 99 Hackathon
It is a GUI on top of W3C-compliant regex validators like w3cgrep and yangre (one of the tools from libyang) so that one can be sure their regexs will work in YANG models.
For context, this was a major issue that Openconfig had. While there were a number of POSIX/Perl validators like regex101.com, there wasn't a W3C one.
After cloning the project, configure config.py with the appropriate paths for the yangre and w3cgrep executables. I had some issues with yangre not finding the right library files, so I included an explicit path to the library. Feel free to remove or customize this as needed.
Once configured, launch the web GUI simply with
python run.py
Note that this is not ideal for production. For use in a production environment, please use nginx or similar.
- Have w3cgrep and yangre installed on the local machine
- Python 3.5
- Flask
The application can also be run using docker. In the docker folder, run
docker-compose build
docker-compose up
Yangre is now available at http://localhost/yangre
- See RFC 7950 section 9.4.5 for details on the YANG regular expressions.
- See RFC 7950 section 6.1.3 for information on quoting
Thanks to Joe Clarke, Radek Krejci, all the testers from IETF and especially Benoit Claise for allowing me to participate! :)
