Installation

From Zed Extensions

1. Open Zed
2. Go to Extensions
3. Search for "duso"
4. Click Install

From Source

cd ~/.zed/extensions
git clone https://github.com/duso-org/duso-zed.git

Requirements

• Duso must be installed on your system. Get it from:
  • Duso Homepage: Download and install binary
  • Homebrew: brew tap duso-org/homebrew-duso && brew install duso
  • GitHub Releases

The extension uses Duso's built-in LSP server (duso -lsp) for all language features.

Configuration

The extension works out of the box with no configuration needed. It automatically:

• Recognizes .du files as Duso scripts
• Launches the LSP server when needed
• Applies syntax highlighting and smart indentation

Getting Started

1. Create a .du file:

touch hello.du

2. Write some Duso:

// Your first Duso script
print("Hello, Duso!")

// Use snippets for quick coding
// Type 'fn' and press Tab to create a function

3. Open the file in Zed - syntax highlighting and LSP features are automatically enabled.

Snippets

Trigger	Expansion
fn	function declaration
if	if statement
ifelse	if/else statement
for	for loop (range)
forin	for-in loop (iteration)
while	while loop
try	try/catch block
parallel	parallel execution block
spawn	spawn process
require	module import
fetch	HTTP fetch

Commands

The extension provides access to Duso's built-in documentation:

• Right-click on any function name
• Hover for information via LSP
• Check the Duso documentation: duso -doc or duso -docserver

Learn Duso

• Official Docs: duso -read (guides and reference)
• Examples: duso -read examples/
• Reference: duso -doc (built-in function reference)
• Website: duso.rocks

Troubleshooting

"Duso not found" error

Make sure Duso is installed and available in your PATH:

which duso
duso -version

Syntax highlighting not working

• Verify the file has a .du extension
• Check that the Duso extension is enabled in Zed
• Reload Zed (Cmd+Shift+P → "Revert to auto-saved copy" or restart)

LSP not responding

• Check that Duso LSP works: duso -lsp (should start without errors, press Ctrl+C to stop)
• Check Zed logs: View → Toggle Developer Console
