What is Neovim?

Neovim is a highly configurable, extensible, and powerful text editor. But that description can be a little intimidating! Let's break it down. It's often described as a "modal editor," which means it operates in different modes. Think of it like a camera: it has different modes for taking pictures, recording video, etc. Neovim has modes for inserting text, navigating the file, and executing commands.

It's a fork of Vim (that's V-I-M), a text editor that's been around for decades and is famous for its efficiency and power. Neovim was created to improve upon Vim, making it more modern, easier to extend, and better suited for collaboration.

Why choose Neovim?

  • Efficiency: Once you learn the keybindings, you can edit text very quickly without taking your hands off the keyboard.
  • Customization: Neovim is incredibly customizable. You can tailor it to your exact needs and preferences.
  • Extensibility: Plugins allow you to add features like code completion, linting, debugging, and much more. It can truly become a full-fledged IDE.
  • Lightweight: Neovim is generally very fast and doesn't consume a lot of system resources.
  • Cross-Platform: It runs on Linux, macOS, and Windows.

Getting Started: Installation

Before you can start using Neovim, you need to install it. The installation process varies depending on your operating system:

  • Linux: Most distributions have Neovim in their package repositories. For example, on Debian/Ubuntu: sudo apt install neovim
  • macOS: The easiest way is to use a package manager like Homebrew: brew install neovim
  • Windows: You can download a pre-built binary from the Neovim releases page. You might also consider using a package manager like Winget, Chocolatey or my favourite Scoop

After installation, you can launch Neovim by typing nvim in your terminal.

Basic Concepts: Modes

Understanding Neovim's modes is crucial. Here are the most important ones:

  • Normal Mode: This is the default mode. You use it for navigating the file, deleting text, copying, pasting, and executing commands. You enter this mode when you open a file or press <Esc>.
  • Insert Mode: This is where you actually type text. You enter this mode by pressing i, a, o, or other insert commands.
  • Visual Mode: This mode allows you to select text. You enter this mode by pressing v (character-wise), V (line-wise), or <Ctrl-v> (block-wise).
  • Command Mode: You enter this mode by pressing :. You use it to execute commands like saving the file, searching, or running shell commands.

Essential Keybindings

Here are a few keybindings to get you started:

  • h: Move cursor left
  • j: Move cursor down
  • k: Move cursor up
  • l: Move cursor right
  • i: Enter Insert Mode (before the cursor)
  • a: Enter Insert Mode (after the cursor)
  • o: Enter Insert Mode (on a new line below)
  • <Esc>: Return to Normal Mode
  • :w: Save the file
  • :q: Quit Neovim
  • :q!: Quit without saving
  • dd: Delete the current line
  • yy: Yank (copy) the current line
  • p: Paste
