IDE Setup

Desi has full IDE support via the Language Server Protocol (LSP).

Quick Start

1. Build the language server:

   make tools
   

2. Add bin/desilsp to your PATH

3. Configure your editor (see below)

VS Code

cd editors/vscode
npm install
code .  # F5 to launch dev host

Or install the packaged extension:

npx vsce package --allow-missing-repository

IntelliJ IDEA / WebStorm / PyCharm

1. Install LSP4IJ plugin
2. Build the Desi plugin:

   cd editors/intellij
   ./gradlew buildPlugin
   

3. Install from build/distributions/desi-language-*.zip

Neovim

Using nvim-lspconfig:

require('lspconfig').desilsp.setup{
  cmd = { 'desilsp' },
  filetypes = { 'desi' },
}

Other Editors

Any LSP-compatible editor works. Configure to run desilsp via stdio:

• Sublime Text: Use the LSP package
• Emacs: Use lsp-mode or eglot
• Helix: Add to languages.toml
