Uncrustify configuration

[TimothyClaeys]

This PR adds the uncrustify configuration file.

You can install the uncrustify binary on Mac OSX, Linux and Windows

• Linux: sudo apt install uncrustify
• Mac OS: brew install uncrustify
• Windows: download from uncrustify

Alternatively you can clone the repo and compile the project yourself (latest version)

To run it on your code use:
uncrustify -c uncrustify-openwsn.cfg -f $FilePath -o $FilePath (makes the changes in-place)

I've applied the configuration to a bunch of files in the firmware project and I think the resulting layout looks nice, is properly aligned, and most importantly, improves code readability.

There are a lot of configuration options (700+) and they are all listed here: . Some options seem to override other ones. The latter can sometimes lead to weird formatting. I tried my best to remove contradicting configuration options, but it is possible some remain.

Before we reformat the entire FW repo, I propose that the people who are developing firmware code first try the uncrustify configuration on their local working trees and see if the configuration makes sense (and if they personally agree with the proposed code layout). If we see that it works well on all the files and we've converged on a fixed code layout/style, we can reformat the entire project once. Next, we can add the uncrustify configuration to the Travis builder to enforce future PRs to adhere to the coding style.

Hi @kyh-ly, I don't think the branch openwsn_FW-881-nrf52840dk is actively maintained at the moment. This is probably why it is broken and does not work with the current version of openvisualizer. Please, in the future, if you have a problem, open a github issue and do not use unrelated PR to ask questions.

@TimothyClaeys Sorry I don't have access to open issues, please tell me how to do this. 😄

@kyh-ly Sorry, apparently, the issues tab was disabled. I enabled it now. If you go the repository's main page:

openwsn-fw

You should now see an Issues tab. Can you open an new issue there for your problem with the NRF52840, and any new issues you might encounter in the future. Thanks.
