Question: How to change `default-directory` when in `consult-ripgrep`

[lynnux]

Hi @minad, I use consult-ripgrep only search current dir not the whole project, code by this:

(defun my-consult-ripgrep(&optional dir)
             (interactive "P") 
             (require 'consult)
             (let  ((consult-ripgrep-args (concat consult-ripgrep-args " --no-ignore")))
               (consult-ripgrep (or dir default-directory)))
             )

and there is a function binding to C-l to change the directory to parent, code like this:

           (defun is-consult-ripgrep()
             (eq 'consult-grep
                 (completion-metadata-get
                  (completion-metadata (minibuffer-contents)
                                       minibuffer-completion-table
                                       minibuffer-completion-predicate)
                  'category)))
           (defun is-consult-line()
             (eq 'consult-location ;; 
                 (completion-metadata-get
                  (completion-metadata (minibuffer-contents)
                                       minibuffer-completion-table
                                       minibuffer-completion-predicate)
                  'category)))
           (defun my/vertico-C-l ()
	     (interactive)
             (if (is-consult-ripgrep)
                 (progn
                   (setq default-directory (file-name-directory (directory-file-name default-directory)))
                   (let ((text (substring-no-properties (or (car-safe vertico--input) ""))))
                     (delete-minibuffer-contents)
                     (insert text)
                     ))
               (call-interactively 'vertico-directory-delete-word)))
(define-key vertico-map (kbd "C-l") 'my/vertico-C-l)

When I invoke C-l, the search result is fine, but the C-n(vertico-next) not work as expect, and RET also not work.

I don't understand what you are trying to achieve but searching a specific directory is possible by pressing C-u first (prefix argument). See the docstring of consult-grep. There shouldn't be the need to write code.

EDIT: I reread your issue again. The problem is that consult-ripgrep does not allow changing the default-directory on the fly. This breaks preview as you discovered since consult--temporary-files captures the default directory in the closure. I don't recall the reasons for why it does that, but I am sure there was a reason. :)

However there is an alternative better way to achieve what you want, which is less fragile. We simply restart the entire command.

(defun consult-ripgrep-up-directory ()
  (interactive)
  (run-at-time 0 nil #'consult-ripgrep
               (file-name-directory (directory-file-name default-directory))
               (ignore-errors
                 (buffer-substring-no-properties
                  (1+ (minibuffer-prompt-end)) (point-max))))
  (minibuffer-quit-recursive-edit))

(consult-customize
 consult-ripgrep
 :keymap (let ((map (make-sparse-keymap)))
           (define-key map (kbd "M-l") #'consult-ripgrep-up-directory)
           map))

Thank you @minad , works like a charm :)
