Welcome to my research pages.

* Add a submodule                                                   :noexport:
#+begin_src emacs-lisp :results none
  (let* ((url (read-string "Add submodule (remote url) "))
         (url-match (string-match "\\([^./]+\\)\\(\\.git\\)?$" url))
         (path (match-string 1 url))
         (path (read-string "Submodule directory " path)))
         (shell-command (concat "git submodule add " url " " path))
         (shell-command (concat "git submodule deinit -f " path)))
#+end_src

* Change submodule url                                              :noexport:
First delete the submodule using
#+begin_src bash
  git rm --cache submodule-name
#+end_src

Then add a new submodule with the updated url.

* Update CSS and JS                                                 :noexport:
#+begin_src bash :results none
