# Description:
# An interactive script for setting DNS records for domains in `domains.txt`.
# The script fetches zones from Cloudflare, prompts the user for DNS type 
# (A or AAAA), the corresponding IP value, and a comment (with a shortcut 
# for "N2 address"). It then creates the specified DNS record for each 
# domain in the file matching with the Cloudflare zones. Ideal for batch 
# setting DNS records.

Emacs packages, features, files, layers, extensions, auto-loading, require, provide, use-package… All these terms getting you confused? Let’s clear up a few things.

Files

Emacs files contains code that can be evaluated. When evaluated, the functions, macros and modes defined in that file become available to the current Emacs session. Henceforth, this will be termed as loading a file.

One major problem is to ensure that all the correct files are loaded, and in the

Install Emacs First

Download emacs-w64 and extract somewhere, e.g. a tools or apps folder like C:\Users\<user>\tools\emacs.

Select Emacs' Home

Emacs and many other applications store its configuration in the user's "home" folder. Translated directly from the Unix world, that is %UserProfile% (C:\Users\<user>), but Windows prefers %AppData% instead (C:\Users\<user>\AppData\Roaming).

For simplicity's sake, override this by specifying the HOME environment variable explicitly. Emacs and some other applications (e.g. MinGW) lets this override the default.

Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.
