split-string case insensitive?

split-string case insensitive?

[pwl_b]

Hi!

I am trying to split a string in eLisp using split-string, and here is
a sample outcome of it:

(split-string "Abcade" "A" t)
=> ("bc" "de")

The question is: Why it does not care about case of "A"? And is there
a way to split string in case-sensitive manner?

The strange thing to me is that split-string does accept regexp as a
separator, but it still doesn't care about the cases e.g.:

(split-string "A1ba2b" "A." t)
=> ("b" "b")

I would appreciate any help given, and I am sorry if this question has
an obvious answer but I couldn't find any on the Web.

Regards,
Paweł.

It depends on the setting of the case-fold-search variable:

(let ((case-fold-search t))
  (split-string "Abcade" "A" t)) --> ("bc" "de")

(let ((case-fold-search nil))
  (split-string "Abcade" "A" t)) --> ("bcade")

It does work! Thanks a lot!
