Ceedling YAML to CMakeLists

[sandyK]

All,

Before I head off on that experimental path, was wondering if anyone on here tried to parse and convert project.yml to Cmake arguments? We use ceedling for unit testing the zephyr application. Figured it would be nice if I could have project.yml as single source of truth for both test and target builds where I provide all source , include directories and defines instead of all the nested CMakeLists.txt. I suppose what am trying to do won't sit nice with spirit of CMake?

Thanks

Hi sandyK

I'm not familiar with Ceedling.

CMake doesn't support YaML natively but since CMake v3.19 there has been support for CMake presets:

https://cmake.org/cmake/help/latest/manual/cmake-presets.7.html

which sounds like what you need, although the format is JSON, not YaML.

As said, I'm not familiar with Ceedling, but it could be worth investigating if it supports JSON in addition to YaML.

Else, conversion between JSON to YaML in Python is quite straightforward when the file are regular text fields.

A draft showing CMake presets in nRF Connect SDK can be seen here: https://github.com/nrfconnect/sdk-nrf/pull/3979

Best of luck and would be appreciated if you drop a line later on your experiences on this path.

best regards

Torsten

Hi Tarsten,

An update. Ended up writing a ruby generator script that is invoked by rake build task . The script takes project configuration parameters from Ceedling (YAML Hashes) and converts to CMakeLists.txt before invoking west. At the moment all sources in subdirectory are listed in CMakeLists.txt in project root unlike how CMakeLists.txt normally likes to live in source subdirectories. That's something I can improve upon in future to be in line with CMake.

Best Regards
