FVim

FVim provides a graphical front‑end for the Neovim editor, built with F# and the Avalonia UI framework. It renders Neovim buffers in a windowed environment, supporting high‑DPI displays, GPU‑accelerated drawing, and smooth cursor animations while preserving Neovim’s theming and color‑scheme conventions. Font handling includes ligature support, Nerd‑font integration, and fallback for East‑Asian glyphs, and the interface can display background images and custom UI elements.

The application runs on macOS, Windows, and Linux, offering installation packages for each platform and the ability to compile from source with .NET 6.0. Users can connect the GUI to local, remote, or WSL‑based Neovim instances, detach editor windows as separate OS windows, and even operate FVim as a terminal emulator. It also supports input‑method handling, a read‑only information scrollbar, and extensibility through a UI Server Protocol for NeoVim plugins.

FVim targets developers who prefer Neovim’s modal editing but want a native desktop experience with advanced rendering, multi‑window management, and fine‑grained font control, while remaining compatible with existing Neovim configuration files.
