Helix

Helix is a modal text editor written in Rust and inspired by Neovim and Kakoune. It implements changes to the traditional Vim workflow similar to Kakoune's, like selection-based editing and multi-cursor support. Helix bundles and enables many features out of the box. It does have adding custom language support and #Plugins support.

Installation

Configuration

Note The launcher binary is renamed as 'helix', due to conflicts with the package hex. Users wishing to use hx instead of helix need to make an alias
