AutoHotkey

AutoHotkey v1 for Zed

Full AutoHotkey v1 support for Zed: syntax highlighting, LSP, and debugging.

Note: Requires Windows (AutoHotkey is Windows-only).

Features

Syntax Highlighting

• Full syntax highlighting for .ahk files
• Auto-indentation and bracket matching

Language Server (LSP)

• Go-to-definition - Navigate to function/class definitions
• Hover documentation - View function signatures and documentation
• Code completions - IntelliSense for AutoHotkey keywords, functions, and variables
• Diagnostics - Real-time error and warning detection
• Document outline - Jump to functions, classes, and labels
• Symbol search - Find symbols across your project

Running Scripts

To enable the "Run" button in the gutter, add a task to your Zed config:

1. Open Command Palette → "zed: open tasks"

2. Add a task with the ahk-script tag:

   [
     {
       "label": "Run AutoHotkey Script",
       "command": "& 'C:\\Program Files\\AutoHotkey\\AutoHotkey.exe'",
       "args": ["$ZED_FILE"],
       "tags": ["ahk-script"]
     }
   ]

   Note: The & '...' syntax is required for PowerShell when the path contains spaces. Adjust the path to your AutoHotkey installation.

3. Click the run button in the gutter or use Command Palette → "task: spawn" (if you don't see the button, try reopening the IDE).

Debugging

Debug AutoHotkey v1 scripts with breakpoints, stepping, and variable inspection.

Features:

• Set breakpoints (click gutter or F9)
• Step over (F10), step into (F11), step out (Shift+F11)
• Inspect local and global variables
• View call stack
• Watch expressions

Setup:

1. Create .zed/debug.json in your project root:

   [
     {
       "label": "Debug Current Script",
       "adapter": "autohotkey",
       "request": "launch",
       "program": "$ZED_FILE",
       "stopOnEntry": true
     }
   ]

2. Open a .ahk file and press F5 or use Command Palette → "debugger: start"

Configuration options:

Note: The debug adapter includes a bundled AutoHotkey runtime. No separate installation required for debugging.

Supported Syntax

Comprehensive AutoHotkey v1 syntax support including:

• Comments, strings, numbers, arrays, and operators
• Control flow (if, while, loop, for, switch, try/catch)
• Functions, classes, objects, and hotkeys/hotstrings
• Built-in commands, variables, and directives

For full AutoHotkey v1 syntax reference, see the official documentation.
