Hello, Unlike project-shell-command, project-compile first prompts for a command, then binds default-directory and calls compile. Binding default-directory first makes completion work from the project root, which is useful for completing on filenames relative to the root, on targets from the toplevel Makefile, etc. I see three ways to achieve this: (1) Rewrite project-compile with call-interactively, the way project-shell-command is written (see patch #1). (2) Set COMMAND to nil in the interactive spec, then prompt for it after binding default-directory (see patch #2). (3) Let-binding default-directory once in the interactive spec, and again before calling compile. I'm assuming (1) is out of the question, given 2020-06-02 "* lisp/progmodes/project.el (project-vc-dir, project-shell): New commands." (2c1e5b9e77). I'm CC'ing Juri to get his opinion though; project-compile is new in Emacs 28.1, so its argument list is not yet set in stone. I've taken a stab at (2), but my patch changes the semantics of COMMAND for an edge case: for now calling (project-compile nil) from Lisp causes (compile nil) to be called (which errors out); with my patch, (project-compile nil) yields a prompt. This can be solved using called-interactively-p (or using an optional INTERACTIVE argument); I just don't know if it's worth the hassle? I haven't given much thought to (3), so I haven't yet figured out how to avoid prompting twice for the project (on the rare occasions where prompting is needed). Thanks for your time.
