;;; Commentary:

;; This library sets some variables for git-email to make it work
;; better with Piem.

;;; Code:

(require 'git-email)
(require 'piem)

;; TODO: Use `piem-merged-inboxes' instead of `piem-inboxes'
;; <https://inbox.kyleam.com/piem/20210610185943.14155-5-kyle@kyleam.com/T/#u>

This will read the `piem-inboxes' variable."
  (let ((inbox (git-email-piem-inbox-by-coderepo)))
    (piem-inbox-get :address inbox)))

(defun git-email-piem-inbox-by-coderepo ()
  "Return the inbox based on the current project."
  (catch 'hit
