I found a bug in my previous regexp-split implementation, and fixed now:

(define* (regexp-split regex str #:optional (flags 0))
(let ((ret (fold-matches

I think it would make a nice addition to (ice-9 regexp). I don't think
we need to capture the delimiters though; some other funct

It's the last optional argument of `split-string'. The last paragraph
in the documentation notes that when you call this function with just
a single argument

That can work, though I personally prefer a sep

OK, I'll put this proc in my own lib since there's no regexp-lib but a
regexp-core in Guile. Anyway, it's almost completed now. One may copy the
final version if needed.

I'm afraid I can't recall what happened following that thread.
What feels important to me, though, is the elegance of the overall API.

Now that we have previous thread on this topic, I think it's no need to
format a patch.
Maybe this will solve the problem:
(define* (regexp-split regex str #:optional (flags 0))
(let ((ret (fold-matches
regex str (list '() 0 str)
(lambda (m prev)
(let* ((ll (car prev))

I notice that this does not handle the case where there are no matches:
scheme@(guile-use
Well, I see.
So the previous discussion didn't make this proc put into Guile?
Now that so many people interested in this topic.

Group capturing is useful, but the quest

We've had this topic before, and it only needs a search for
"regex-split guile" to find it:
http://old.nabble.co
I just expressed "I think group capturing is useful and someone didn't
think that's true".
If this is not what your last mail mean, I think it's better to ignore it.

Hmm, interesting!
I must confess I'm not familiar with Racket, but I think the aim of Guile
contains practicality.
So I think regex-lib of Guile does this at least.
Anyway, I believe an implementation should do its best to provide any
useful mechanism for the user. Or it won't be popular anymore.

`regexp string' is also
Well, I realized it's a mistake. We can use fold-matches anyway.

hi Daniel! Very glad to see your reply.
1. I also think the order: (regexp str) is strange. But it's according to
python version.
And I think the 'string-match' also put regexp before str. Anyway, that's
an easy mend.
2. I think it's a little different to implement a flag as python version.

It seems like there's no "regexp-split" procedure in Guile.
What we have is "string-split" which accepted Char only.
So I wrote one for myself.
