Severity: wishlist
Tags: patch

Currently, if you want to construct a regexp which includes a runtime
values using rx, there are two options:

- Use the (eval FORM) subform.  But if using using the rx macro, FORM is
  evaluated at macroexpansion time, which is awkward.  If using
  rx-to-string, then FORM can't access the lexical environment, which is
  also awkward.
- Build a list at runtime and pass to rx-to-string.  This requires the
  whole rx translation infrastructure at runtime, which is sad.

The patch below allows the rx macro to generate a concat expression
instead of just a plain string.  So the example from
https://debbugs.gnu.org/35564#53 would become

    (let ((start (max 0 (1- pos)))
          (char (string (aref command pos)))) ; need string for `regexp-quote'.
      (and (string-match
            (rx (or (seq (or bos blank)
                         (group-n 1 (regexp-quote char))
                         (or eos blank))
                    (seq ?` (group-n 1 (regexp-quote char)) ?`)))
            command start)
           (= pos (match-beginning 1))))

The rx call in the above macroexpands into:

    (concat "\\(?:\\`\\|[[:blank:]]\\)" "\\(?" "1" ":"
            (regexp-quote char)
            "\\)" "\\(?:\\'\\|[[:blank:]]\\)" "\\|" "`" "\\(?" "1" ":"
            (regexp-quote char)
            "\\)" "`")

Which will be optimal once we apply the patch from #14769 "optimize
`concat's literals".

Subject: [PATCH] Support (rx (and (regexp EXPR) (regexp-quote EXPR)))

* lisp/emacs-lisp/rx.el (rx-regexp): Allow non-string forms.
(rx-constituents): Add regexp-quote constituent, which is like a plain
STRING form, but allows arbitrary lisp expressions.
(rx-regexp-quote): New function.
(rx-compile-to-lisp): New variable.
(rx-subforms): New helper function for handling subforms, including
non-constant case.
(rx-group-if, rx-and, rx-or, rx-=, rx->=, rx-repeat, rx-submatch)
(rx-submatch-n, rx-kleene, rx-atomic-p): Use it to handle non-constant
subforms.
(rx): Document new form, wrap non-constant forms with concat call.
* test/lisp/emacs-lisp/rx-tests.el (rx-tests--match): New macro.
(rx-nonstring-expr, rx-nonstring-expr-non-greedy): New tests.
* etc/NEWS: Announce changes.

+---
 *** The rx 'or' and 'seq' forms no longer require any arguments.
 (or) produces a regexp that never matches anything, while (seq)
 matches the empty string, each being an identity for the operation.
 This also works for their aliases: '|' for 'or'; ':', 'and' and
 'sequence' for 'seq'.

+*** 'regexp' and new 'regexp-quote' accept arbirtray lisp as arguments.
+In this case, 'rx' will generate code which produces a regexp string
+at runtime, instead of a constant string.
