SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides working with Neovim configuration including testing changes headlessly, managing plugins with lazy.nvim, configuring LSP servers, and troubleshooting startup errors. Use this when modifying nvim config files or debugging nvim issues.

Core Features & Use Cases

Headless testing: Validate Neovim config changes without launching the UI.
Plugin health checks: Ensure plugins load correctly via headless tests.
LSP configuration: Set up language servers with mason.nvim for streamlined development.
Troubleshooting: Debug startup and plugin loading issues to reduce downtime.
LSP verification: Test LSP attachment and functionality in a headless environment.
Deterministic plugin management: Use lazy.nvim for predictable plugin behavior.

Quick Start

Test Neovim loads headlessly: nvim --headless -c "echo 'Config loaded successfully'" -c "quit" 2>&1
Test a plugin load in headless mode: nvim --headless -c "lua print('Plugins loaded')" -c "quit" 2>&1
Validate LSP setup (Mason/LSPConfig): nvim --headless -c "lua print('LSP config initialized')" -c "quit" 2>&1

FAQPage Schema

How do I test Neovim configuration changes without launching the UI?▼

Test Neovim headlessly using nvim --headless -c "echo 'Config loaded successfully'" -c "quit" 2>&1 to validate config changes without starting the graphical interface. This identifies startup errors before full launch.

How can I verify plugins load correctly in Neovim?▼

Run headless plugin load checks with nvim --headless -c "lua print('Plugins loaded')" -c "quit" 2>&1 to confirm lazy.nvim plugins initialize properly without UI overhead, catching load failures early.

What's the best way to set up LSP servers in Neovim?▼

Configure language servers using mason.nvim for package management and nvim-lspconfig for attachment, then validate with headless tests. This ensures deterministic LSP setup across Unix environments.

Can I test LSP attachment in a headless environment?▼

Yes, verify LSP configuration with nvim --headless -c "lua print('LSP config initialized')" -c "quit" 2>&1 to check that language servers attach correctly without launching the editor UI.

Why does my Neovim fail to start, and how do I debug it?▼

Debug startup errors by running headless tests that isolate plugin loading and LSP initialization issues. Headless validation identifies which config file or plugin causes failures before interactive launch.

Do I need Neovim 0.9 or later to use lazy.nvim and LSP configuration?▼

Yes, this skill requires Neovim 0.9+ with Bash, a standard config layout at ~/.config/nvim, and lazy.nvim for deterministic plugin management and LSP setup via mason.nvim.
