Thanks for the PR, @calebhearth. I think adding an ability to have a global .swift-format configuration without putting .swift-format in / will be useful.
A couple comments regarding the search locations:
- I think we should also support
XDG_CONFIG_DIRSfor a system-wide configuration file isntead of just a user-wide configuration file. - We should also offer default search locations on Windows, the Build Server Protocol uses
%LOCALAPPDATA%\bsp\and%PROGRAMDATA%\bsp\and I think we could do the same here. - The search path discovery for BSP servers is implemented in SourceKit-LSP at https://github.com/swiftlang/sourcekit-lsp/blob/4ca25836226a2b28868a42df3a3336fcc481e1c5/Sources/BuildSystemIntegration/ExternalBuildSystemAdapter.swift#L195-L220. I think you should be able to steal a lot of that (especially note that there are methods in Foundation to get the path for the
Application Supportdirectories). Also, I think it makes sense to follow that precedent for ranking the XDG-dirs vsApplication Support.

@WuerfelDev opened the PR, but I second the thanks! |

Oh, whoops, sorry. @WuerfelDev thank you for opening the PR 🙏🏽 |

I will make the changes within the next week. However I am unable to test on windows Thanks for the SourceKit link, I'll get some "inspiration" from there |
That’s fine. Just try and do the best you can think of, leaving FIXMEs for things that you know need covering and I can do the rest. |

@ahoppen Thank you so much for guiding me through this feature implementation, being new to swift I've learned a bunch of things along the way |

Sorry, I only now noticed: Do we ever add nil to this array? I don’t think so and we wouldn’t need to do case var location? in the loop below if we don’t allow optionals in here.
Searches for configuration files (
swift-format/config.json) in the config directories (~/Library/Application Support,$XDG_CONFIG_HOME,.config).That enables a "global" (userwide) configuration that is stored eg in the dotfiles.
The configuration file is only used when no other configuration file was found
