Is there any way to excecute :post-build with sudo?

[Lodger]

Hello, I have this recipe for EMMS:

'(emms
   :type git
   :flavor melpa
   :files ("*.el" "lisp/*.el" "doc/emms.texinfo" "emms-pkg.el" "src/*")
   :repo "https://git.savannah.gnu.org/git/emms.git"
   :post-build (("make" "emms-print-metadata") ("mv" "src/emms-print-metadata" "/usr/local"))))

However, to run mv src/emms-print-metadata /usr/local, I need root permission via sudo. Is there anyway to do this?

Is the goal to run the command as root without any prompt for your password, or do you want to be prompted for your password?

[Lodger]

ideally I would like to be prompted, but either way would be acceptable

:post-build commands can be arbitrary elisp or system processes. I haven't tried it, but you may be able to set up an askpass program and write a script which prompts for a password when you need it.

Yep, that would be the way to do it. straight.el won't be able to do a tty prompt (due to complications with how async processes work), so you'll need some additional configuration.

That said, might it be a better idea to reconfigure whatever dependency wants the EMMS stuff installed in /usr/local so that it can read the configuration out of your home directory instead? That seems like it could potentially be cleaner.

This was the perfect solution, didn't realize i could customize emms-info-libtag-program-name :p, thanks!
