 Journalscript tries to use the editor the `EDITOR` variable set in your environment. If it is absent, then it defaults to `vim`. However you can configure journalscript to use any editor of choice with the `JOURNALSCRIPT_EDITOR`. For example edit `journalscript.env` and replace the default `JOURNALSCRIPT_EDITOR="vim"` with `JOURNALSCRIPT_EDITOR="emacs"`, `JOURNALSCRIPT_EDITOR="nvim"`, `JOURNALSCRIPT_EDITOR="code"`, etc.
