Restart command in different directory

[indigoviolet]

Similar to #596, is there a way to change the directory of an arbitrary consult command after we have already entered the prompt?

For example, let's say I'm using consult-find, I can start it with a prefix to prompt for a directory; but if I've already entered consult-find, I can't change the directory I'm searching in.

It would be nice to be able to invoke the directory prompt with some keypress and return to the consult-find command. I can kind of do this via consult-dir, by setting consult-dir-default-command, but not generically - since I don't know how to get the current consult command.

Any suggestions?

You can adapt the solution from #596. In order to obtain the current command you could store this-command in a minibuffer-setup-hook. See for example Marginalia or Embark which use this technique. Emacs 28 comes with the current-minibuffer-command variable which should hold the relevant command name, but I haven't tried this variable so far.

I'm curious if anyone ever wrote a snippet for this that they'd like to share.

I'm trying to reproduce some muscle-memory from Helm; specifically, helm-rg, which allows me to type M-d when I'm in the middle of a grep to switch into "select a directory" mode.

It would be very convenient if this were something that had a general purpose solution. Unfortunately I'm not much good at ELisp myself.
