| # cn-cbor: A constrained node implementation of CBOR in C |
| |
| This is a constrained node implementation of [CBOR](http://cbor.io) in |
| C that I threw together in 2013, before the publication of |
| [RFC 7049](http://tools.ietf.org/html/rfc7049), to validate certain |
| implementability considerations. |
| |
| Its API model was inspired by |
| [nxjson](https://bitbucket.org/yarosla/nxjson). It turns out that |
| this API model actually works even better with the advantages of the |
| CBOR format. |
| |
| This code has been used in a number of research implementations on |
| constrained nodes, with resulting code sizes appreciably under 1 KiB |
| on ARM platforms. |
| |
| I always meant to improve the interface some more with certain API |
| changes, in order to get even closer to 0.5 KiB, but I ran out of |
| time. So here it is. If I do get around to making these changes, the |
| API will indeed change a bit, so please be forewarned. |
| |
| ## Building |
| |
| There is a `Simple-Makefile` for playing around, as well as a complete |
| [`cmake`](http://www.cmake.org)-based build environment. |
| (You can choose what fits your needs better.) |
| |
| Building with `cmake`: |
| |
| ./build.sh |
| |
| Building including testing: |
| |
| ./build.sh all test |
| |
| Generating a test coverage report (requires lcov[^1]; result in `build/lcov/index.html`): |
| |
| ./build.sh all coveralls coverage_report |
| |
