How to find all places in a project, where overridden ~= is used?
问题
extension String {
static func ~= (lhs: String, rhs: String) -> Bool {
guard let regex = try? NSRegularExpression(pattern: rhs) else { return false }
let range = NSRange(location: 0, length: lhs.utf16.count)
return regex.firstMatch(in: lhs, options: [], range: range) != nil
}
}
我找不到一种方法来查找项目中使用了这个重写函数的所有位置。
在这种情况下，Cmd+Ctrl+Shift+H 不起作用。
你可以说：“只需搜索代码库中的~=符号”。
但~=也隐式用于评估switch-case操作符。
用例：
假设我想更改~=函数的逻辑（我真的想这样做）。
我确切地知道，我还必须修复使用这个函数的地方的代码。
否则，这些switch-case将不正确地工作（编译器不会显示任何警告）。
附言：
作为解决方案的示例：搜索代码库中的所有switch出现，并在其中仅查找switch String/case String。
这正是我所需要的。
这种方法的唯一问题是：这将花费我几个小时（如果不是几天）🤣
英文:
extension String {
static func ~= (lhs: String, rhs: String) -> Bool {
guard let regex = try? NSRegularExpression(pattern: rhs) else { return false }
let range = NSRange(location: 0, length: lhs.utf16.count)
return regex.firstMatch(in: lhs, options: [], range: range) != nil
}
}
I can’t figure out a way to find all places in a project, where this overridden function is used.
Cmd+Ctrl+Shift+H doesn’t work in this case for some reason.
You can say: “Just search for ~= symbols in the codebase”.
But ~= is also implicitly used for evaluation of switch-case operators.
Use case:
Let’s say I want to change the logic of the ~= function (and I really do). And I know for sure, that I also have to fix the code in places, where this function is used. So I need to find all the switch-cases where it is used. Otherwise these switch-cases will become work incorrectly (and the compiler will not show any warnings).
P. S.
As an example of a solution: to search for all the switch appearance in the codebase and among them look only for switch String/case String. That would be exactly what I need.
The only problem with this approach: it will take me hours (if not days) 🤣

如果您要弃用覆盖，那么您只需查看编译器警告。
extension String {
@available(*, deprecated, message: "Found it")
static func ~= (lhs: String, rhs: String) -> Bool {
guard let regex = try? NSRegularExpression(pattern: rhs) else { return false }
let range = NSRange(location: 0, length: lhs.utf16.count)
return regex.firstMatch(in: lhs, options: [], range: range) != nil
}
}
英文:
What if you were to deprecate the override? Then you just have to look through your compiler warnings.
extension String {
@available(*, deprecated, message: "Found it")
static func ~= (lhs: String, rhs: String) -> Bool {
guard let regex = try? NSRegularExpression(pattern: rhs) else { return false }
let range = NSRange(location: 0, length: lhs.utf16.count)
return regex.firstMatch(in: lhs, options: [], range: range) != nil
}
}
