GNvim - Rich Neovim GUI without any web bloat

GNvim, Neovim GUI aiming for rich code editing experience without any unnecessary web bloat.

GNvim has been my daily driver since August 2018. I try to add new features as I find time for it, and any help is welcome!

For more screenshots, see the wiki.

TL;DR to get started on Ubuntu 18.04 after cloning this repo and assuming you have rust tool chain installed:

$ sudo apt install libgtk-3-dev
$ # Run (unoptimized version) without installing
$ GNVIM_RUNTIME_PATH=/path/to/gnvim/runtime cargo run
$ # Install
$ make && sudo make install

macOS

$ brew install rust gtk+3 librsvg
$ # Install
$ make && sudo make install

Features

No electron (!), build on GTK.
Ligatures
Animated cursor
Animated scrolling
A lot of the nvim external features implemented
- Popupmenu
  - Own view for preview (:h completeopt).
- Tabline
- Cmdline
- Wildmenu

More externalized features will follow as they are implemented for neovim.

Requirements

GNvim requires

Stable rust to compile
Latest nvim release or master
Gtk version 3.20 or higher

On some systems, Gtk packages doesn't include development files. On Ubuntu, you'll need the following ones:

$ sudo apt install libgtk-3-dev

For other systems, see requirements listed by gtk-rs project here.

There are some benchmarks for internal data structures, but to run those you'll need nightly rust. To run those benchmarks, use cargo bench --features=unstable command.

Install

You're required to have rust tool chain available. Once you have that, clone this repo and run make build followed by sudo make install.

Running

TL;DR: Without installing:

GNVIM_RUNTIME_PATH=/path/to/gnvim/runtime cargo run

GNvim requires some runtime files to be present and loaded by Neovim to work properly. By default, GNvim will look for these files in /usr/local/share/gnvim/runtime, but this can be changed by specifying the GNVIM_RUNTIME_PATH environment variable.

GNvim will use nvim to run Neovim by default. If you want to change that, you can use --nvim flag (e.g. gnvim --nvim=/path/to/nvim).

For debugging purposes, there is --print-nvim-cmd flag to tell GNvim to print the executed nvim command.

See gnvim --help for all the cli arguments.
