Subject: bug#66260: 29.0.92; project.el should support copying a file path relative to the project root
Date: Thu, 28 Sep 2023 23:26:41 +0000 (UTC)

When communicating with others, it is often useful to copy a file path
to the current file which is relative to the project root.  For example
I'd rather send someone the path lisp/progmodes/project.el than
~/src/emacs/trunk/lisp/progmodes/project.el.

project.el should have a way to copy this file path.

Almost good enough is:

 C-x p f       ;; project-find-file
 M-n	       ;; next-history-element
 C-k	       ;; kill-line

but with project--read-file-cpd-relative, if all the files in
project-files start with a common-parent-directory which is a
subdirectory of project-root, the resulting file path will not be
relative to the project-root but to the subdirectory.

Maybe the thing to do is just make project--read-file-cpd-relative use
project-root instead of calculating a common-parent-directory?  I would
be happy to make that patch if that's acceptable.  I think that's
probably the best option.

Alternatively, it might be cool if there was a variation on:

 C-x C-j     ;; dired-jump
 M-0	     ;; digit-argument
 w	     ;; dired-copy-filename-as-kill

(which copies an absolute path) to instead copy a project-root-relative
path.
