Nvmm

Nvmm is a sweet Neovim GUI for Mac with GPU text rendering and native Mac look and feel.

It comes bundled with nvim and a CLI helper called nvmm.

Nvmm runs on macOS 15.7+ and Apple Silicon.

Nvmm shown with vim-buftabline, a plugin that makes Neovim's tabs make sense.
It works well with Nvmm's option to prefer buffers over tabs.

Installation

Pre-built releases are published on the GitHub Releases page.

Documentation

See Nvmm Documentation.

Build

By default, the app gets an ad-hoc signature. No Apple Developer account is required.

First, download Neovim 0.12 or newer. The build copies it into the app. Then build the app:

Scripts/download_nvim.sh v0.12.6
xcodebuild -configuration Release

The app is built at:

build/Release/Nvmm.app

Updates use Sparkle. A stripped-down build of it is committed at Frameworks/Sparkle.framework. To rebuild it from a Sparkle release:

Scripts/build_sparkle.sh 2.10.0

The app uses its bundled Neovim unless you choose another one in Settings. See Choosing a Neovim.

Run the tests with:

xcodebuild -project Nvmm.xcodeproj -scheme Nvmm \
  -destination platform=macOS test

Signing with Your Team

To sign with your own Apple Developer team, copy the example signing file:

cp Config/Signing.local.xcconfig.example \
  Config/Signing.local.xcconfig

Then edit Config/Signing.local.xcconfig and replace XXXXXXXXXX with your team ID. As provided, it signs Debug with Apple Development. To sign Release with Developer ID, uncomment its Release lines. Keep each setting's [config=...] part so it only affects that configuration. Any configuration you leave out keeps the ad-hoc signature.

Git ignores this file. Set up signing there, not in Xcode's Signing & Capabilities editor, because Xcode saves those choices in the shared project file.
