in thread Regex Search String in a Variable

°) alas not in GnuEmacs. XEmacs had "raw strings", but became abandon-ware.

While it does not provide raw strings, I've always found the rx macro to offer a very neat solution for building complicated regular expressions, somewhat akin to Perl's /x flag:

(rx "\\x2"
    (one-or-more nonl)
    "\\x4")

    that's true, but you still need two \\ to quote a meta.

    here a bad but not exceptional line taken from cperl-mode

    "\\((\\(\\\\.\\|[^\\\\()]\\|([^\\\\()]*)\\)*)\\)?"

    edit

    and more things need escaping in elisp regexes
