xvr.nvim

Neovim tree-sitter based syntax highlighting and filetype support for the XVR programming language.

Features

• Tree-sitter based syntax highlighting for XVR
• Filetype detection (.xvr files)
• Code folding support
• Syntax-based textobjects

Installation

Using :TSInstall (Recommended)

First, install the plugin via your plugin manager, then run:

:TSInstall xvr

Using lazy.nvim

{
  'xvrlang/xvr.nvim',
  lazy = true,
}

Requirements

• Neovim 0.12+
• nvim-treesitter installed

The plugin will automatically install the XVR tree-sitter parser.

Quick Setup

Ensure you have nvim-treesitter installed and configured:

-- In your plugins/init.lua
{
  "nvim-treesitter/nvim-treesitter",
  opts = {
    ensure_installed = { "xvr" },
    highlight = { enable = true },
  },
}

The plugin handles the rest automatically.

Manual Parser Installation

If you need to install manually:

# In the xvr.nvim plugin directory
npm install -g tree-sitter-cli
tree-sitter generate
cc -shared -o xvr.so -fPIC -Os -I./src src/parser.c
mkdir -p parser && mv xvr.so parser/
