Search for all files *not* containing a string in VS Code
There is a VS Code extension called Reverse Search It can find files that do not contain a specific string
In general regex, to search for anything that does not contain a certain string, you do stringbefore(?!string)
That is a negative lookahead, it says that only match if whatever you specify as string
is not present. In your case it would be something like [\W\w]+(?!OnPush)
But, Negative Lookaheads aren't supported in VS Code Search... So you can't do much.
