That just highlights some confusion about Emacs. It’s more akinto Unix and the shell as a whole. That’s why I said VM. If you know perl and have a whole host of utils from a unix box, you can script the workflow you want quite easily, especially if you have access to the cpan libraries.
The same thing can happen with emacs. There’s a lot of low level interfaces (network, process,…) and some high level ones regarding the UI. Then there’s a lot of utils andd whole software built with those. All modifiable quite easily. As another commenter had put it, you don’t even need to save a file. You just write some code, eval it, and you have your new feature. If you’re happy with it, you add it to your config or create a new module (very simple). So elisp covers the whole range from simple configuration to whole software.
