WeChat Send

Send messages to WeChat contacts by automating the macOS WeChat desktop app.

Prerequisites

• WeChat for Mac installed and logged in
• macOS Accessibility permission granted to node (System Settings → Privacy & Security → Accessibility)
• WeChat window must be open (not minimized to dock)

Usage

Run the scripts:

# Send text
bash scripts/wechat_send.sh "<contact_name>" "<message>"

# Send an image (or any file attachable by WeChat)
bash scripts/wechat_send_image.sh "<contact_name>" "/path/to/image.png"

Examples

# Send a simple message
bash scripts/wechat_send.sh "Ryan" "你好！"

# Send a longer message
bash scripts/wechat_send.sh "Ellison" "明天下午3点开会，别忘了带文件"

# Send a screenshot
bash scripts/wechat_send_image.sh "Family" "/Users/you/Desktop/screen.png"

How It Works

1. Activates WeChat and opens search (Cmd+F)
2. Types the contact name, selects the first result (Enter), closes search (Escape)
3. Clicks the message input field using JXA CGEvent mouse simulation
4. Pastes the message from clipboard (Cmd+V) and sends (Enter)

Limitations

• Contact name must exactly match a WeChat contact (first search result is selected)
• Image/file sending depends on WeChat accepting paste-from-clipboard as an attachment (works for common formats like PNG/JPG)
• Cannot read incoming messages
• WeChat window position affects click coordinates (auto-calculated from window bounds)
• If the contact search returns wrong results, the message goes to the wrong person — use specific names
• Only one message at a time; for multiple recipients, call the script multiple times

Troubleshooting

• Message not sent: Ensure WeChat window is visible (not minimized) and the correct contact was found
• Accessibility error: Re-grant node permission in System Settings → Accessibility, then restart the gateway
• Wrong contact: Use a more specific name to avoid ambiguous search results
