Rather than only adapt refactoring actions that conform to
SyntaxRefactoringProvider, which takes a syntax node and produces a
syntax node, adapt to the less-constraining EditRefactoringProvider,
which takes a syntax node and produces edits. We can map edits over
just as effectively.
This change includes a number of new refactoring code actions that
build on the syntax refactorings for the SwiftRefactor module of swift-syntax:
* Add digit separators to an integer literal, e.g., `1000000` ->
`1_000_000`.
* Remove digit separators from an integer literal, e.g., 1_000_000 ->
1000000.
* Format a raw string literal, e.g., `"Hello \#(world)"` ->
`##"Hello\#(world)"##`
* Migrate to new if let syntax, e.g., `if let x = x { ... }` ->
`if let x { ... }`
* Replace opaque parameters with generic parameters, e.g.,
`func f(p: some P)` --> `func f<T1: P>(p: T1)`.
This is generally easy to do, requiring one conformance to provide a name for the refactoring:
extension AddSeparatorsToIntegerLiteral: SyntaxRefactoringCodeActionProvider {
public static var title: String { "Add digit separators" }
}
