This splits out the .clang-format settings from the .clang-tidy file.
Right now, the .clang-tidy file has a bit of a mix: it contains both
clang-tidy checks and clang-format style options.
This actually works fine in some tools (like CLion which doesn't
completely fail), but newer versions of clangd-based tools (VSCode,
Neovim, etc.) are stricter and will outright reject the config because
they expect .clang-tidy to only contain tidy-related stuff.
So here's what I did:
- Moved all the formatting-related options into a brand new
.clang-format file
- Kept .clang-tidy focused only on checks, warnings-as-errors, and any
check-specific options
No changes to the actual style rules or tidy checks. Everything should
behave exactly the same as before.
This should now play nicely with clangd, VSCode/VSCodium, Neovim, and
other modern clang-based tools, while still working perfectly in CLion.
I did this because some/*my* PRs had some formatting errors that could
be prevented in the future, thus lessing the work while
reviewing/merging.
Test the old .clang-tidy with
```
clang-tidy --dump-config
./.clang-tidy:13:1: error: unknown key 'SpaceBeforeCaseColon'
... more errors
```
