Neovide

This is a simple graphical user interface for Neovim. Where possible there are some graphical improvements, but it should act functionally like the terminal UI.

I've been using this as my daily driver since November 2019. It should be relatively stable, but I'm still working out some kinks and ironing out some cross platform issues. In general it should be usable at this point, and if it isn't I consider that a bug and appreciate a report in the issues! Any help and ideas are also greatly appreciated.

I'm also very interested in suggestions code quality/style wise when it comes to Rust. I'm pretty new to the language and appreciate any critiques that you might have to offer. I won't take all of them, but I promise to consider anything you might have to offer.

Features

Should be a standard full features Neovim GUI. Beyond that there are some visual niceties:

Ligatures

Supports ligatures and full HarfBuzz backed font rendering.

Animated Cursor

Cursor animates into position with a smear effect to improve tracking of cursor position.

Emoji Support

Font fallback supports rendering of emoji not contained in the configured font.

More to Come

I've got more ideas for simple unobtrusive improvements. More to come.

Install

Currently there is just a Windows binary under the project releases. I'm hoping to automate and produce Mac and Linux binaries as well, but I haven't gotten there yet.

Installing should be as simple as downloading the binary, making sure nvim.exe with version 0.4 or greater is on your path, and running it. Everything should be self contained.

Building

Building instructions are somewhat limited at the moment. All the libraries I use are cross platform and should have support for Windows, Mac, and Linux. The rendering however is Vulkan-based, so driver support for Vulkan will be necessary. On Windows this should be enabled by default if you have a relatively recent system.

Note: Neovide requires neovim version 0.4 or greater.

Windows

Install the latest version of Rust. I recommend https://rustup.rs/
Ensure graphics libraries are up to date.
git clone https://github.com/Kethku/neovide
cd neovide
cargo build --release
Copy ./target/release/neovide.exe to a known location and enjoy.

Mac

Install the latest version of Rust. I recommend https://rustup.rs/
Install the Vulkan SDK. I'm told brew cask install apenngrace/vulkan/vulkan-sdk works, but I can't test locally to find out.
git clone https://github.com/Kethku/neovide
cd neovide
cargo build --release
Copy ./target/release/neovide to a known location and enjoy.

Linux

Instructions to build on Ubuntu

sudo apt-get update -y
sudo apt-get install -y vulkan-sdk

Install Rust

curl --proto '=https' --tlsv1.2 -sSf "https://sh.rustup.rs" | sh
