Neovim plugin for LUMOS schema language with Tree-sitter syntax highlighting and LSP support.

• Syntax Highlighting: Full Tree-sitter grammar for .lumos files
• LSP Integration: Auto-completion, diagnostics, hover, and more via lumos-lsp
• Smart Keybindings: Pre-configured keymaps for common LSP operations
• Formatting: Format on save support

1. Neovim 0.9+ (for Tree-sitter and LSP support)
2. lumos-lsp: LUMOS Language Server

   cargo install lumos-lsp

3. nvim-treesitter: Tree-sitter integration for Neovim
4. nvim-lspconfig: LSP configuration framework

{ "getlumos/nvim-lumos", dependencies = { "nvim-treesitter/nvim-treesitter", "neovim/nvim-lspconfig", }, config = function() require("lumos").setup() end, }

use { "getlumos/nvim-lumos", requires = { "nvim-treesitter/nvim-treesitter", "neovim/nvim-lspconfig", }, config = function() require("lumos").setup() end, }

1. Clone this repository:

   git clone https://github.com/getlumos/nvim-lumos ~/.local/share/nvim/site/pack/lumos/start/nvim-lumos

2. Install Tree-sitter parser:

   cd ~/.local/share/nvim/site/pack/lumos/start/nvim-lumos git clone https://github.com/getlumos/tree-sitter-lumos

3. Add to your init.lua:

   require("lumos").setup()

require("lumos").setup()

require("lumos").setup({ -- Custom options (currently none, reserved for future) })

If you want to manually configure Tree-sitter:

require("nvim-treesitter.configs").setup({ ensure_installed = { "lumos" }, highlight = { enable = true, }, })

To customize LSP behavior:

local lspconfig = require("lspconfig") lspconfig.lumos.setup({ on_attach = function(client, bufnr) -- Your custom on_attach logic vim.keymap.set("n", "gd", vim.lsp.buf.definition, { buffer = bufnr }) vim.keymap.set("n", "K", vim.lsp.buf.hover, { buffer = bufnr }) end, capabilities = require("cmp_nvim_lsp").default_capabilities(), })

These keybindings are automatically set up for .lumos files:

nvim-lumos/ ├── ftdetect/ │ └── lumos.lua # File type detection for .lumos files ├── lua/ │ └── lumos/ │ ├── init.lua # Main plugin entry point │ └── lsp.lua # LSP configuration ├── queries/ │ └── lumos/ │ └── highlights.scm # Syntax highlighting queries ├── LICENSE-MIT ├── LICENSE-APACHE └── README.md 

The plugin provides syntax highlighting and LSP support for:

• Structs: struct Player { ... }
• Enums: enum GameState { ... }
• Attributes: #[solana], #[account], #[deprecated]
• Types:
  • Primitives: u8, u16, u32, u64, u128, i8, i16, i32, i64, i128, bool, String
  • Solana: PublicKey, Signature
  • Collections: Vec<T>, Option<T>, [T]
• Comments: // line comments, /* */ block comments

#[solana] #[account] struct PlayerAccount { wallet: PublicKey, level: u16, experience: u64, inventory: Vec<Item>, } #[solana] enum GameState { Active, Paused { reason: String }, Finished(u64), }

1. Verify lumos-lsp is installed:

   which lumos-lsp

2. Check LSP logs:

   :LspLog

3. Restart LSP:

   :LspRestart

1. Ensure nvim-treesitter is installed

2. Check Tree-sitter parser status:

   :TSInstallInfo lumos

3. Force reinstall parser:

   :TSInstall lumos
