#243

I'm not sure about the category. (I put #242 into basics, but app development seems better now^^)

[Phaiax]

I stole this one from the regex crate

Hi @Phaiax thanks for all the submissions!

Unfortunately I'll not be able to follow up with anything resembling review for the next two weeks due to holidays 😞 . I may drop some comments when Im on mobile later and I've asked other maintainers to drop from time to time and look into the PR's.

To answer your unspoken question, regex examples would go to basics section (atm the distinction between basics and app is quite arbitrary and this will change in the future)

Hi @Phaiax nice work! just some quick comments from mobile to help out the next reviewer

• this example would go into basics

also some of the comments in #247 are applicable.

please add

 ```rust 

otherwise the testrunner will not compile nor run it.

Almost perfect! I would only suggest to update PR description with fixes #243 to autoclose the issue on merge.

also I would mention the key identifiers (replace_all) with links and docs about the capture groups.
