Activate rgrep from isearch

I'd like to be able to switch from an isearch query directly into rgrep (interactively) such that rgrep defaults to using for the full isearch query string. The default behavior of rgrep is to use the symbol under the cursor, but this doesn't work well if the isearch query contains spaces.

This recipe from EmacsWiki almost does what I want, but it calls rgrep non-interactively whereas I'd like to call it interactively:

Solution

  • Alright just figured it out — this seems to work:

    (define-key isearch-mode-map "\C-xg"
  (lambda()
  (interactive)
  (let ((read-regexp-defaults-function (lambda nil
                                         (if isearch-regexp
                                             isearch-string
                                           (regexp-quote isearch-string)))))
    (isearch-exit)
    (call-interactively 'rgrep))))
