Can regexp2 provide the same APIs adapt to std.regexp? about regexp2 HOT 5 OPEN

I’m assuming gostd.regexp is the go standard library regexp package.

This package isn’t designed to be a drop-in replacement for the standard library.

At first blush a conversation layer doesn’t seem too difficult so it seems like a project that requires swapping between them could write a normalization layer.

Have you tried writing this layer yourself and run into problems? Are there specific functions or concepts from regexp you want that aren’t present in regexp2?

I am doing some heavy regexp processing, what need back-reference syntax from regexp library, which is not supported by std.regexp.
I found regexp2 meet all what I need.

I have try to export this APIs at https://gitee.com/gxlb/gogp/blob/dev_gt/vendor/github.com/dlclark/regexp2/regexp_api.go
But failed today, I'll try latter.
It will be greatfull if regexp2 directly adapt all APIs from std.regexp library.

I have sucessfully replaced std.regexp with regexp2.
When I finish adapt other unused APIs, may I put a PR to regexp2 to compatibility with std.regexp APIs?

Sure! Be sure to document the compatibility goal in the README and include tests.

Here is something that I want to do on regexp2 next:

1. Add compatibility with std.regexp APIs
2. Add coverage test cases
3. Add examples of APIs usage
