VIM Editor

What is Vim?

Vim is a text editor for Unix that comes with Linux, BSD, and macOS. It is known to be fast and powerful, partly because it is a small program that can run in a terminal (although it has a graphical interface). It is mainly because it can be managed entirely without menus or a mouse with a keyboard.

For the following five reasons, I feel people should use Vim:

  1. It's omnipresent. You don't have to think about learning about several boxes with a new editor.
  2. It is highly scalable. You can use it only to edit configuration files or become your entire forum for writing.
  3. It has a shallow memory footprint.
  4. It's command-centered. With a few commands, you can perform complex text-related tasks.
  5. It is highly configurable and uses simple text files to store its settings.

Why Use Vim?

In all POSIX systems, Vim is the default fallback editor. Vim is sure to be open, whether you have just installed the operating system, or you have booted into a minimal system repair environment, or you are unable to access any other editor. While you can switch out other tiny editors on your systems, such as GNU Nano or Jove, it's Vim that's all but guaranteed to be on every other system in the world.

In short, I think competence with Vim should be considered the way you view competence with your native language, or simple maths, etc.
