How to translate this input surrounding?

[xigoi]

I see the custom surrounding system for mini.surround has changed. I have this input surrounding defined using the old system:

input = { find = "%b[]", extract = "^(%[[^%s%[%]]*%s*).*(%])$" },

How do I translate it to the new system? The guide in the documentation can't be applied because ane pattern for find doesn't contain the pattern for replace,

I am not sure why documented approach wouldn't work.

Does next setting behave not the same as this one?

input = { "%b[]", "^%[[^%s%[%]]*%s*().*()%]$" },

Oh, probably because one example shows those patterns merged together. It doesn't need to be, it was just an example.

Transition should literally just be:

• Remove find = and extract = .
• Move ( of left match to its right part (forming ()).
• Move ) of right match to its left part (also forming ()).
