[-- Attachment #1: Type: text/plain, Size: 861 bytes --]

In order to make `project-recompile' symmetric to `recompile' it should
be autoloaded and it should run in the project root. This makes it
possible to call `project-recompile' directly without calling `compile'
first.

    ;;;###autoload
    (defun project-recompile (&optional edit-command)
      "Run `recompile' with appropriate buffer."
      (declare (interactive-only recompile))
      (interactive "P")
      (let ((default-directory (project-root (project-current t)))
            (compilation-buffer-name-function
             (or project-compilation-buffer-name-function
                 compilation-buffer-name-function)))
        (recompile edit-command)))

This change also resolves the comment in project-recompile:

    ;; Should we error instead?  When there's no
    ;; project-specific naming, there is no point in using
    ;; this command.

Thanks, I've pushed this to master.

The comment is related to the previous thread (bug#68570), and it's 
still unresolved, but IIUC this doesn't make things worse, at least.

Cc'ing Juri just in case.

Agreed, this is the right thing to do.

Isn't bug#68570 solved by bug#70136?

Thanks for installing the patch! I just saw that the docstring should
probably also updated accordingly. Maybe like this:

"Run `recompile' in the project root with an appropriate buffer."

Now that you mention it, the solution proposed in bug#70136 does seem 
like the right direction. So we can hope for having it resolved there.

Thank you, pushed now too.
