Having some trouble setup a template with "#i"

[Inc0n]

Whilst the provided examples as shown below works perfectly fine.

(inc "#include <" (p (concat (file-name-base (or (buffer-file-name) (buffer-name))) ".h")) ">")

I would like to if possible setup another such template with "#i" instead, here is what I have so far

(\#i "#include <" (p (concat (file-name-base (or (buffer-file-name) (buffer-name))) ".h")) ">")

The slash \ is needed to escape the '#' for the emacs lisp reader. And thus I thought this should complete the setup. However, even then it's still not usable when I try it in an actual c-mode buffer. Emacs minibuffer showing the message of user-error: tempel-expand: No completions is not only mildly infuriating but also defeating.

It does appear that following test does return t so theoretically a template with "#i" is technically possible?

(eq (car (with-temp-buffer
        (insert "(\n  \\#i")
        (goto-char (point-max))
        (insert "\n)")
        (goto-char (point-min))
        (read (current-buffer))))
    '\#i)

I am at a loss for what possible information I am lacking in possesion to make this work, hence, needing to make a post to seek external expertise for aid. It should go without a saying that any help or suggestions will be greatly appreciated.

Maybe you want to use tempel-trigger-prefix instead?
