Just went through the examples. Seems really intuitive and looks like it would be a good approach for homegrown linters. Would also love to see some plugin support for editors.

Agreed. What editors do you have in mind?

I filed a ticket for VS Code support because I’ve seen it mentioned in a few of the other comments: https://github.com/returntocorp/semgrep/issues/1329

VS Code and vim would be the ones I would be most concerned about as I typically jump between the two. Although a pre-commit hook is great and something I will definitely use, having this hook reporting issues in a more live manner would be a huge bonus.
