I implemented a format-agnostic search that can match patterns across various naming conventions like camelCase, snake_case, PascalCase, kebab-case. If needed, I'll integrate in space-separated words.
I've just published the tool to PyPI, so you can easily install it using pip (`pip install super-grep`), and then you just run it from the command line with `super-grep`. You can let me know if you think there's a smarter name for it.
If you do, email a link to hn@ycombinator.com and we'll put it in the second-chance pool (https://news.ycombinator.com/pool, explained at https://news.ycombinator.com/item?id=26998308), so it will get a random placement on HN's front page.
