[Proposal] add "split" function - array[string] split(string $separator, string $subject)

[morokin]

Just copy of issue opened by @biochimia: jmespath/jmespath.site#35

I propose the addition of a split() function, counterpart to the already standard join() function. split breaks a string into an array of substrings that are separated by $separator in the original $subject.

(Not entirely unlike Python's string.split() function)

Personally I also looked for the split function (I'm heavily using jmespath in ansible playbooks). I mean - it's little bit uncomfortable to have join function and not to have split

Maybe the concrete Python implementation is also not the right place for this issue, as the language specific implementation follows the spec... so the right place for the enhancement wishes is the spec, which has no own repository, but lives in the site? :)

Here or there, I'd also be interested in the feature.

I'd be interested to hear an idea from the project maintainer how we can go about implementing such enhancements ourselves. The issue and pull requests in the project seem to be pretty abandoned.
@jamesls are you still working on the project?

We also have an issue with the absence of a string split() function which could transfor a string to a new array of values. We receive a JWT data structure which is parsed in Grafana using JMESPath for role mapping. The groups claim inside the JWT hasn't an array but a character-delimited list of groups like "|group|another|andanother|" and i'd love to have split functionality for these bogus values. I am perfectly aware that it is a problem with the system which sends the token, but i really would like to be able to fix this in-place instead of adding something like a preprocessing proxy.
