ComfyUI LoRA Hook + Trigger Text Node

A clean and simple ComfyUI custom node that:

• Creates a LoRA Hook through comfy_extras.nodes_hooks.CreateHookLora
• Automatically finds and loads trigger TXT files placed in a folder named after the LoRA file
• Provides a trigger selection combo box in the UI
• Outputs both the generated Hook and the selected trigger text

This node is designed to make using LoRA-specific trigger text easier and fully automated.

🔧 Features

• Automatic detection of TXT trigger files next to each LoRA
• Clean UI combo box for selecting trigger names
• Safe TXT reading with UTF-8 / UTF-8-SIG / CP949 fallback
• No external dependencies required
• Minimal, stable design that works across any ComfyUI installation

📁 Folder Structure Example

These are generic examples, not user data.

models/
└── loras/
    ├── my_lora.safetensors
    └── my_lora/
        ├── trigger1.txt
        ├── style.txt
        └── preset_prompt.txt

Rules:

• The folder name (my_lora) must match the LoRA file name without extension
• Every .txt file inside that folder will appear in the trigger selector
• If no TXT files are found, the trigger list defaults to:

["NONE"]

🛠 How It Works (Simplified)

Python (__init__.py)

• Defines the custom node class
• Provides an HTTP endpoint /lora_trigger_list
• Locates the LoRA path using ComfyUI's folder_paths
• Scans the corresponding folder for TXT files
• Reads the selected TXT file
• Builds the LoRA Hook with CreateHookLora

JavaScript (js/lora_trigger_ui.js)

• Inserts a trigger dropdown into the node UI
• Hides the raw trigger STRING field
• Syncs the UI value back into the node
• Calls the server endpoint to update available triggers

---

⚙ Requirements

• ComfyUI (latest recommended)
• No additional dependencies
• Works on all operating systems supported by ComfyUI
