How to grep/search over all packages?

Hi Julia Devs,

Guess the subject basically says it all. But, to make it more concrete, a couple of packages I’ve tried to use crashed over the same issue, generating a :macrocall expression. The fix was similar, and it should quite possibly apply wherever such an expression is generated. So, hence, a search over all packages is needed.

Of course, I could clone all of them, but a more online/centralized way would be nice to have. might help.

This only covers registered packages, and it takes up a bit of space to clone them all, but I have a few scripts at that I use for exactly this.
