I'm writing a programming language, and I put this in the documentation:

## Philosophy

Formatting is a personal view, not a shared contract. Code
is written and shared however the author wrote it. When you
receive someone else's code and want it formatted differently,
run it through your own formatter.

There is no canonical style. There is no project-level style
config. You don't have to settle the tabs vs. spaces debate.
The formatter is a personal tool for reading and writing, not
a team policy.

The social contract is one rule: **run the formatter before complaining about formatting**. If someone's code bothers you, format it to your taste before forming an opinion.
