Installation

VS Code

Install Ignition Dev Tools from the VS Code Marketplace.

The language server is installed automatically on first activation. No manual setup required.

Neovim (lazy.nvim)

Minimal (uses defaults from lazy.lua — lazy-loads on filetype + commands, auto-installs LSP):

{ 'TheThoughtagen/ignition-nvim' }

With custom options:

{
  'TheThoughtagen/ignition-nvim',
  opts = {
    lsp = {
      enabled = true,
      auto_start = true,
      settings = {
        ignition = {
          version = "8.1",
        },
      },
    },
    kindling = {
      enabled = true,
    },
    decoder = {
      auto_decode = true,
      auto_encode = true,
    },
  },
}

LSP Server (manual)

Both editors auto-install the LSP, but you can also install it manually:

pip install --extra-index-url https://test.pypi.org/simple/ ignition-lsp

Monorepo Structure

packages/
├── ignition-lsp/        # Python LSP server (shared by both editors)
├── ignition-nvim/       # Neovim plugin (Lua)
└── ignition-vscode/     # VS Code extension (TypeScript)

Top-level symlinks (lua/, lsp/, ftdetect/, etc.) allow the repo to work directly as a Neovim plugin when installed via lazy.nvim.

Claude Code Integration

Give Claude Code full Ignition awareness — API reference, expression language, and auto-linting — so it writes correct Ignition scripts out of the box.

Option A: Plugin (global, works across all projects)

claude plugin add --from whiskeyhouse/ignition-nvim --path claude-code-plugin

Option B: Templates (per-project, check into your repo)

curl -sL https://raw.githubusercontent.com/whiskeyhouse/ignition-nvim/main/templates/setup.sh | bash

See claude-code-plugin/README.md and templates/README.md for details.

Part of the Whiskey House Ignition Developer Toolkit
