would we perhaps want a input.replace "\d" " " cleanse too? (like Duplicate_Whitespace, except always replacing with spaces - for example, 'foo bar\t\t baz')

although it probably wouldn't be too late to only add that only when someone actually has a usecase for it...

So operator78170.replace (regex "\d") ' ' exists today. But do you mean the ability to use our named regexs in replace?

That is an interesting idea...

I understood as ability for the regex to replace the number not with empty "", but with single whitespace " ". Not sure if that was what you meant @somebody1234 ?

But I'm writing because this also struck a chord with me - I was thinking that with this method when cleaning e.g. [a,b,c] from all non-letters, I will get abc. Often that is what I want. But it feels to me that I may also want to get a b c. For example for language processing tasks, if I want to do some naive cleanup of punctuation before tokenization, I want foo:bar, baz... Hmm? to probably become foo bar baz Hmm, so that I can then split it on " " to get all the tokens. (Of course if foo:bar should become foo bar or actually foobar is highly use-case dependent.)

But essentially this stems the idea if maybe we should be able to control if the cleansing should "preserve separation between words". I.e. by default we replace everything with "", but we could have an alternative mode where we kind of replace everything with " " and then do remove duplicate whitespace as the last step to normalize all separators to be a single space.

But it feels like this is complicating this rather simple tool, so maybe that is not really what we want at this stage for this component. Just throwing ideas around.

whoops my bad, i meant "\s+" " " :sweat_smile:
