The sheer number of backslashes my regexps require is pretty crazy. Does elisp have regexp literals, so I can write something like
One option is to use the
rx macro to construct your expressions using sexps.
Your example becomes
(rx "some" (group "regexp"))
Here are a couple more examples from the commentary section in rx.el, to get an idea of how
(rx (or (and line-start ";;" (0+ space) ?\n) (and line-start ?\n)))
(rx (and (zero-or-more (in " \t\n")) ":" (submatch (or line-end (one-or-more (not (any ?:)))))))
No it does not have regexp literals, but many find pcre2el to be a helpful alternative.
Specifically using it from elisp like this:
(rxt-pcre-to-elisp "(abc|def)\\w+\\d+") ;; => "\\(\\(?:abc\\|def\\)\\)[_[:alnum:]]+[[:digit:]]+"
