It might be best if you stuck with the C coding style used by Christophe Devine when he originally wrote the package.

Hello,
You are concerned if: you contribute to Mbed TLS, or you maintain local patches to Mbed TLS. You are not concerned if: you just use Mbed TLS.
We are going to change the C coding style in Mbed TLS. The new style is mostly what you'd find in The C Programming Language, 2nd edition, by Brian Kernighan and Dennis Ritchie (K&R2). The main changes compared to the current style are:
* Spaces outside parentheses, not inside. No space in f(x). * Opening braces on the same line as if(), for(), etc., but on a separate line for functions.
Indentation remains 4 spaces. The recommended maximum line length remains 80 columns. There are a few deviations from K&R2, documentation will be available shortly.
The new code style will be enforced by the CI testing. This means that style that's rejected by the tool will not be merged, full stop. This also means that sometimes we'll have code that looks a bit less good to humans because the tool insists on it. We're doing this to avoid wasting reviewers' and contributors' time with style violations in code review.
The tool we're using is uncrustifyhttps://github.com/uncrustify/uncrustify. You can see how your code will look like by installing uncrustify 0.75.1 and running scripts/code_style.py from mbedtls-3.3.0 or mbedtls-2.28.2. There are previews of the rewritten branches at https://github.com/Mbed-TLS/mbedtls/tree/features/new-code-style/development and https://github.com/Mbed-TLS/mbedtls/tree/features/new-code-style/mbedtls-2.2... (updated every few days until the real branches are rewritten). If you're now starting work on a new feature or bugfix, it will probably be easier to start from those branches, and do an easy rebase once they become official.
If you've been working on a branch, we will provide a script to rebase the branch and rewrite it to the new style commit by commit. You'll need to have uncrustify 0.75.1.
Concretely, when we change the code style:
* If you've started to work on a branch but review has not started yet, we'll ask you to adapt your branch to the new code style. * If your work is under review, you'll need to adapt your branch to the new code style before it can be merged. Rebasing a branch is disruptive for reviews, so please synchronize with the reviewers to decide on a good time.
We plan to do the switch during the first week of January 2023.
Best regards,
