Temporary case-folding in string-match()

Temporary case-folding in string-match()

[Nordlöw]

If I normally use case-folding, how do I *temporarily* set case-fold-
search to nil when doing string-match()?

(let (case-fold-search)
  (string-match ...))

or string-match-p, if you don't need the match data.

If you often want to do that, you can define your own function

(defun my-string-match (regexp string &optional start case-fold-search)
  "Like `string-match', with a local binding of `case-fold-search'."
  (string-match regexp string start)

so you can use it like a non-case-folding string-match, and if you
ever need the case-folding, you just do

  (my-string-match my-regexp my-string nil t)

(let (case-fold-search)
  (string-match ...)
  ...)
