Switching to Neovim as a Full IDE: A Vim User’s Experience

#

I’ve used vi and vim for 25 years, mostly for quick edits: config files, scripts, remote server work. For actual development I used heavier IDEs. After seeing Neovim used as a full IDE by a couple of developers I follow, I decided to set it up properly and see if it could replace PyCharm as my daily driver. It did.

Key Takeaways

#

• Neovim with LazyVim is a viable full IDE replacement for PyCharm — with comparable LSP support for Python, Rust, Go, and Lua out of the box
• Existing vim muscle memory transfers directly; LazyVim builds IDE features around modal editing rather than layering on top of it
• The which-key popup (Space, then wait) surfaces all available keybindings contextually — you don’t need to memorize the keymap upfront
• On Windows, Lazygit can’t prompt for SSH passphrases; add your keys to ssh-agent before launching or git integration silently breaks
• Config is plain Lua files — trivial to version control and pull down to any machine

Setup Overview

#

I set this up on Windows using Chocolatey. The core dependencies are Neovim itself, a C compiler for building Treesitter parsers, ripgrep and fd for file search, and Node.js for some of the language servers. A Nerd Font is required in your terminal or you’ll get missing icon characters instead of the UI elements.

For the IDE layer I went with LazyVim, which is a Neovim distribution that ships a solid default configuration. Rather than building a config from scratch, LazyVim gets you a working IDE baseline immediately. Language support for Python, Rust, Go, and Lua is enabled through LazyVim’s extras system, which handles pulling in the correct language servers, formatters, and linters for each language automatically via Mason.

Lazygit handles git operations. On Windows there is one gotcha: Lazygit can’t prompt for SSH key passphrases the way the command line can, so if your keys have passphrases you need to add them to ssh-agent first. Once that’s sorted, git integration works well.

Total setup time was a few hours, most of it reading documentation rather than executing steps.

Vim Commands in an IDE Context

#

The main question I had going in was how well vim’s modal editing would translate to a full IDE workflow. The answer is: better than expected. LazyVim preserves the modal editing model and builds the IDE features around it rather than on top of it. Existing vim muscle memory carries over directly. Buffers, motions, commands all behave as expected.

The mouseless workflow is one of the more immediate practical benefits. If you’re already comfortable with vim modes and commands, there is very little relearning. Navigation, file search, code actions, and git operations all stay on the keyboard.

Learning Curve

#

I forced myself to use it for writing blog posts before using it for code. I had Claude generate a workflow cheat sheet covering common operations including Lazygit interactions, and kept it open for reference. By the third post I was mostly working from memory. By the sixth I had customized the config to generate boilerplate and scaffold project structures.

The which-key popup (triggered by pressing Space and waiting) is worth mentioning. It displays available keybindings contextually, so you don’t need to memorize the full keymap up front. It makes the learning curve more manageable than it might otherwise be.

Practical Notes

#

Configuration lives in a standard directory and is just Lua files, so it’s straightforward to version control and pull down to any machine. That portability is one of the more practical advantages over a GUI IDE.

I would recommend this setup to developers and sysadmins who are already comfortable with vim. The workflow gains are real and it handles Python, Rust, Go, and Lua well. It is not a practical choice for teams that need to standardize tooling or onboard people quickly. For individual power users it is worth the setup time.

Which-Key

#

Press <Space> in Normal mode and wait. A popup displays all available keybindings grouped by category. Press any prefix key (g, ], [, z) and wait to see context-specific bindings. This covers the full keymap without memorization.
