Add configuration option to only run swift format when a .swiftformat file exists

[adam-fowler]

I'd like to enable this extension universally, but it means if I work on a project which isn't using swift format it applies the default formatting to it when I'd rather it did nothing. The existence of a .swiftformat file is a pretty good indicator that swift format is being used.

Can we add a configuration option to only run swift format is a .swiftformat file exists in the base of the project

Thanks for the great suggestion!
I'll try to implement this within the next two weeks.

Has been released as 1.4.0.

Within the next few minutes, I will also publish updates for vknabel/vscode-apple-swift-format and vknabel/vscode-swiftlint which implement the same feature.

{
  "swiftformat.onlyEnableWithConfig": true,
  "apple-swift-format.onlyEnableWithConfig": true,
  "swiftlint.onlyEnableWithConfig": true
}
