I myself found a cool plugin that makes it easy, its called logpress, got it
off codecanyon, cost a couple bucks, but definitely worth it.

Hi Claude,

When I'm developing new plugins I run a full mirror of my sites on a
localhost to test the plugin across multiple datasets and structures, but
the secondary benefit is that I can use the cross file search capacity of my
editor to quickly do a bulk search across thousands of files.

I'm 100% sure that you're right, there must be a better way to handle this
and I'd love to know how but for me, the fastest way to detect depreciated
functions is oddly similar to your own.
