📦 ComfyUI-E-Tier-TextSaver

Sick of annoying <pad> tokens messing up your prompts? 😂 This one’s for you.

A secure and flexible text-saving node for ComfyUI.
After captioning with Florence2 or similar, it automatically strips unwanted tokens and saves a clean .txt file.

---

✨ Key Features

• ✅ Removes unwanted tokens like <pad> from caption text
• 🔐 Strict path validation and filename sanitization
• 🧩 Works smoothly with Florence/BLIP captioning nodes
• 📂 Supports LoRA-style image-text dataset workflows

---

🧑‍💻 Use Case Example

When training LoRA models, it's common to need .txt caption files that match image filenames.
This node makes that easy by fitting naturally into a workflow like this:

[Image Loader] ➡️ [Captioning Node] ➡️ [Text Saver (E-Tier)]

---

🔐 Security Design

All save paths go through strict validation checks:

| ✅ Allowed | ❌ Blocked | |-------------------------------|----------------------------------------------------------| | Existing directories only | Non-existent paths (no auto-creation) | | Absolute paths | Relative traversal (e.g., ../) | | Safe characters | Shell/metacharacters (e.g., |, ;, $, etc.) | | Clean text input | Suspicious patterns (e.g., eval, <script>, etc.) |

📌 The final save path is clearly printed to the console for full transparency.

⚙️ Node Parameters

| Parameter | Description | |-------------|----------------------------------------------------| | text | The text content to be saved (required) | | filename | Filename for the resulting .txt file (required) | | save_to | Output directory selected from a dropdown list |

---

About the save_to Parameter

The save_to dropdown paths are specified in the node's YAML whitelist file. Users can set custom keys (names) and their corresponding directory paths in the YAML whitelist like this:

whitelist:
  ComfyUI/output: "./ComfyUI/output"
  CustomFolder: "./my_custom_output"

Here, "CustomFolder" is the label shown in the dropdown, and "./my_custom_output" is the actual directory path used for saving files.
This allows flexible and user-friendly naming of output locations.

---

❗ Other Notes

• Any validation errors will be clearly displayed in the console or UI.
• If no filename is given, it defaults to "untitled.txt".
• This node will not create directories — make sure your structure exists.
• Secure by default, but configurable for advanced users.
