Errors using reflowMultilineStringLiterals

[rgoldberg]

In my .swift-format, I tried to use:

{
  "reflowMultilineStringLiterals": "onlyLinesOverLength",
  …
}

But I get:

$ swift-format lint example.swift
<unknown>: error: Unable to read configuration for /Users/user/example.swift: The data couldn’t be read because it isn’t in the correct format.

$ swift-format --version
601.0.0

$ swift --version
swift-driver version: 1.120.5 Apple Swift version 6.1 (swiftlang-6.1.0.110.21 clang-1700.0.13.3)
Target: arm64-apple-macosx15.0

$ sw_vers
ProductName:		macOS
ProductVersion:		15.4
BuildVersion:		24E248

If I remove "reflowMultilineStringLiterals": "onlyLinesOverLength", from my .swift-format, I don't get any errors.

How can I set reflowMultilineStringLiterals to onlyLinesOverLength without getting errors?

This error has been solved in #979 and waiting the swift-format team's review.

For current workaround, you could use

"reflowMultilineStringLiterals": {
  "onlyLinesOverLength": {}
}

if you want the reflowMultilineStringLiterals to work when formatting.
