The yakyak is all but a solved problem in many languages.in c++ Clang format on submission, and clang format on updating files to your preferred local syntax.
No kidding. The number of projects and developers that I see that refuse to use the tools is quite interesting. One project I worked on dozens of engs say 'your code is so easy to read'. Then one dude comes along and it 'gives him a headache'. He also spent way too much time refactoring and renaming things. He became obsessed by it. Every few weeks changing the spacing, indentation, and naming conventions. Then expecting everyone to keep up with whatever decision he made at 10PM on some random Friday 3 weeks ago in a fit of open every file and change everything. He looked like the hardest working person in the group but he was adding zero new features. It killed the project. The worst are the groups that say 'everyone is a professional we do not have to deal with that'. You then end up with dozens of modules with whatever rando style they happen to like that day. Pick one. Put it in the tool. Stick to it for a decent amount of time. If it is not working bring it up in a meeting.
The ‘black’ formatting tool for python has worked amazingly for my projects. It may be controversial, but I think Python’s strong opinions on code format and conventions was one of the things it got right.
It might be solved for the very basic stuff (spacing, indentation, etc), but there's still plenty of yakyak to be had for higher-order "religious" debates...
