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

GNvim has been quite stable for the past 6+ months and it has been my daily driver since last August, but ymmv. I try to add new features as I find time for it (any help is welcome!). You can usually find me on the neovim gitter.

Find some screenshots here

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 libwebkit2gtk-4.0-dev
$ # Run (unoptimized version) without installing
$ GNVIM_RUNTIME_PATH=./runtime cargo run
$ # Install
$ make
$ sudo make install

• No electron (!), build on GTK.
• Ligatures
• Custom cursor tooltip feature to display markdown documents. Useful for implementing features like hover information or signature help (see gnvim-lsp).
• 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.

GNvim requires

• Stable rust to compile
• Latest nvim master (gnvim 0.1.0 works with nvim 0.3.4)
• Gtk version 3.18 or higher

On some systems, Gtk packages doesn't include development files. On Ubuntu 18.04, you'll need the following ones:

$ sudo apt install libgtk-3-dev libwebkit2gtk-4.0-dev

For other systems, see requirements listed by gtk-rs project here. Note that you'll need the libwebkit2gtk-4.0-dev package too.

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.

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.

TL;DR: Without installing:

GNVIM_RUNTIME_PATH=./runtime cargo run

GNvim requires some runtime files to be present and loaded by nvim to work properly. By default, gnvim will look this files from /usr/local/share/gnvim/runtime, but this can be changed by GNVIM_RUNTIME_PATH environment variable.

By default, gnvim will use nvim to run neovim. 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.
