nmux is a multiplexer for Neovim processes. It is very much a work in progress at the moment.

It currently has a built-in HTTP server that renders a single nvim process in your browser using websockets as a proof-of-concept. Short video of nvim rendered in a browser: https://youtu.be/mzfHBPHkT-E

The browser client was made mainly for prototyping. Native GUI clients for Linux, macOS, and Windows are being worked on.

Neovim must be installed and nvim available in $PATH.

There is an unstable Darwin (macOS) binary available. Windows and Linux builds will be available in the future.

You can also install it with Go:

$ go get -u github.com/tweekmonster/nmux/cmd/nmux

To run the server:

$ nmux --server --addr localhost:9999

To use Neovim in a browser, go to http://localhost:9999/

Note: The browser client has been tested and works in Google Chrome. The keyboard currently doesn't work in Firefox or Safari. If you're using an extension that gives you vi functionality, it will need to be disabled.

If you're using the Darwin release:

$ nmux.app/Contents/MacOS/nmux --server --addr localhost:9999

Then run nmux.app to connect to the server. If you're using a port other than 9999, you will need to run the client the same way, but without the --server flag. A future release will allow you to configure a remote server and optionally spawn a local server.

• A server that manages multiple nvim processes.
  • Allow clients to connect over TCP.
  • Shared unnamed register between all nvim processes.
• Native cross-platform client programs.
  • Each nvim instance can be a tab or a split view.
  • UI is always consistent. No platform-specific GUI elements, except for the title bar.
  • Image replacements for glyphs (in-editor icons).
  • Basic OS integration (clipboard, notifications, open URLs, etc.)
• "Simplified" configuration.
  • Only basics need to be configured for client programs.
    • Client programs can be scripted and configured via vimscript.
  • No need to configure a terminal emulator or tmux. nvim can already be configured and scripted to no end.

The ultimate goal is to create native client apps that connect to the nmux server, making the terminal emulator an obsolete program in my daily work. This is not an attempt to create a new terminal emulator—nvim already has reliable terminal emulator built-in through libvterm.

This will make it possible to turn a Docker container or Virtual Machine (possibly even WSL) into your "IDE". You could take a snapshot of your workspaces and resume where you left off after a reboot.
