;;; test-org-noter-config--title-to-slug.el --- Tests for cj/org-noter--title-to-slug -*- lexical-binding: t; -*-
;;; Commentary:
;; Tests for `cj/org-noter--title-to-slug'. The function lowercases its
;; input, replaces every run of non-alphanumeric characters with a
;; single hyphen, and trims leading/trailing hyphens. It's used to
;; turn a book title into a filename-safe slug.
;;; Code:
