# Neovim Configuration
|
|
|
|
Portable Neovim configuration using lazy.nvim, Mason-managed tooling, native LSP, native Treesitter, Telescope, and DAP (Neovim 0.11+, tested on 0.12.1).
|
|
|
|
## Installation
|
|
|
|
### Standalone (any system)
|
|
```bash
|
|
git clone git@github.com:itme-brain/nvim.git ~/.config/nvim
|
|
```
|
|
|
|
### As part of NixOS config
|
|
```bash
|
|
git clone --recurse-submodules git@github.com:itme-brain/nixos.git
|
|
```
|
|
|
|
## Features
|
|
|
|
- **Native LSP** (`vim.lsp.config` / `vim.lsp.enable`) - no manual server list needed
|
|
- **Smart LSP picker** (`<leader>css`) - auto-detects installed servers for current filetype
|
|
- **Neovim 0.12 compatible** - uses built-in `:lsp` commands and keeps legacy `:Lsp*` aliases working
|
|
- **Portable** - Mason is the source of truth for LSP servers and debug adapters
|
|
- **Treesitter** - uses Neovim's native `vim.treesitter.*` APIs without `nvim-treesitter`
|
|
- **Debugging** - lazy-loaded `nvim-dap` stack with Mason-managed adapters
|
|
|
|
## LSP Setup
|
|
|
|
Mason installs the shared LSP baseline on every system:
|
|
- `lua_ls` - Lua/Neovim
|
|
- `nil_ls` - Nix
|
|
- `bashls` - Bash/Shell
|
|
- `jsonls` - JSON
|
|
- `html` - HTML
|
|
- `cssls` - CSS
|
|
- `marksman` - Markdown
|
|
- `taplo` - TOML
|
|
- `yamlls` - YAML
|
|
|
|
On NixOS, Mason-installed binaries require `nix-ld` so downloaded tools can execute. The NixOS module should provide `nix-ld`; Neovim itself does not keep a separate Nix-only LSP package list.
|
|
|
|
The smart picker (`<leader>css`) scans all lspconfig servers and shows only those with binaries installed.
|
|
On Neovim 0.12+, start/stop/restart uses the built-in `:lsp` commands under the hood.
|
|
|
|
## Treesitter
|
|
|
|
Treesitter uses Neovim's native API:
|
|
- Highlighting starts through `vim.treesitter.start`
|
|
- Parser/filetype mappings use `vim.treesitter.language.register`
|
|
- Parser and query installation is intentionally outside lazy.nvim and Mason
|
|
|
|
Neovim loads compiled parser libraries from `parser/` directories on `runtimepath` and query files from `queries/<language>/`.
|
|
`tree-sitter-cli` is only needed by tools that generate or compile parsers from grammar sources; it is not required at runtime for highlighting.
|
|
Prefer providing parsers and queries through Neovim's runtime or a reproducible system/development environment.
|
|
|
|
## Debugging
|
|
|
|
Debugging uses `nvim-dap`, `nvim-dap-ui`, `nvim-dap-virtual-text`, `telescope-dap.nvim`, and `mason-nvim-dap.nvim`.
|
|
|
|
The DAP stack is lazy-loaded. Normal startup does not load DAP; it loads only when a `:Dap...` command runs or a `<leader>d...` mapping is used.
|
|
|
|
Mason installs:
|
|
- `debugpy` - Python
|
|
- `codelldb` - C/C++/Rust
|
|
- `bash-debug-adapter` - Bash
|
|
- `js-debug-adapter` - JavaScript/TypeScript
|
|
|
|
