Hi folks, I'll be talking about this at Linaro Connect in Hong Kong later today (I believe the session with be recorded and put on YouTube; I'll send the link when it is). Rob and I have been working on a prototype implementation of schema checking written in Python, using YAML schema files and using the JSON Schema vocabulary. Here's the link to the project on GitHub: https://github.com/robherring/yaml-bindings Look at the README file for instructions on setting up the environment (might be buggy; works on my machine, but Rob had problems with it ... Will try to make it more robust tomorrow) Please remember that this is prototype code and I am not suggesting it is ready to use. What it does do in very few lines of Python code (about 250 lines, plus 75 lines of test code) is implement a basic tool which validates both devicetrees, and devicetree schema files. At this stage it is a conceptual design, but it doesn't yet work with the devicetree files in the kernel. It does work with a YAML-transcoded copy of the Juno devicetree in the tests/ directory. You can run the validator against the Juno file with the following command: $ ./dt-validate.py tests/juno.cpp.yaml You can run the test cases just by running: $ make test Finally, you can see an example of a schema file failing validation tests with this command: $ make demo-bad-schema If you run that from within Vim, it will map the errors back to lines of source code. Cheers, g. -- To unsubscribe from this list: send the line "unsubscribe devicetree-spec" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
