ComfyUI Text Split Node

ComfyUI Text Split Node

⛔ DEPRECATED – Moved to https://github.com/vsaan212/Vsaan212-workflow-utilities

A custom ComfyUI node that splits text into multiple outputs for feeding complex multi-scene renders. This node allows you to dynamically control the number of splits and use custom separators.

Features

• Single Text Input: Accepts any text input for splitting
• Custom Separators: Use any string or regex pattern as a separator
• Dynamic Output Count: Control the number of splits (1-8 outputs)
• Text Processing Options: Trim whitespace and remove empty parts
• Regex Support: Use regex patterns for advanced splitting

Installation

Automatic Installation

1. Run the install.bat script to check dependencies and install the node
2. Copy this folder to your ComfyUI custom_nodes directory
3. Restart ComfyUI

Manual Installation

1. Copy this folder to your ComfyUI custom_nodes directory
2. Install any dependencies listed in requirements.txt (if any)
3. Restart ComfyUI

Usage

Basic Usage

1. Add the "Text Split" node from the "text" category
2. Connect your text input to the node
3. Configure the separator (default: |)
4. Set the number of splits (1-8)
5. Connect the outputs to other nodes

Input Parameters

• text: The input text to split (multiline supported)
• separator: Custom separator string or regex pattern
  • Simple string: |, ,, ;, etc.
  • Regex pattern: /pattern/ (e.g., /\\s+/ for multiple spaces)
• num_splits: Number of splits to create (1-8)
• trim_whitespace: Whether to trim whitespace from split parts
• remove_empty: Whether to remove empty parts

Outputs

The node provides dynamic text outputs based on the num_splits parameter:

• text_1 through text_n (where n = num_splits)
• remainder - Contains any leftover text after the specified number of splits

Dynamic Behavior:

• When num_splits is 2: Shows text_1, text_2, and remainder
• When num_splits is 5: Shows text_1, text_2, text_3, text_4, text_5, and remainder
• Unused outputs are hidden in the GUI but still available for connection

Examples

Example 1: Simple Split

Input: "Scene 1|Scene 2|Scene 3"
Separator: "|"
Num Splits: 2
Output: 
  text_1: "Scene 1"
  text_2: "Scene 2"
  remainder: "Scene 3"

Example 2: Regex Split

Input: "Scene 1   Scene 2   Scene 3"
Separator: "/\\s+/"
Num Splits: 2
Output:
  text_1: "Scene 1"
  text_2: "Scene 2"
  remainder: "Scene 3"

Example 3: Multi-scene Prompt with Remainder

Input: "A beautiful sunset|A stormy night|A peaceful morning|A dark forest"
Separator: "|"
Num Splits: 3
Output:
  text_1: "A beautiful sunset"
  text_2: "A stormy night"
  text_3: "A peaceful morning"
  remainder: "A dark forest"

Use Cases

• Multi-scene Renders: Split complex prompts into individual scene descriptions
• Batch Processing: Process multiple text inputs simultaneously
• Conditional Prompts: Create variations of prompts for different scenarios
• Text Analysis: Split text for further processing by other nodes

Technical Details

• Category: text
• Input Types: STRING, INT, BOOLEAN
• Output Types: STRING (up to 8 outputs)
• Dependencies: None (uses Python standard library only)
• Minimum Python Version: 3.7
• Compatibility: Python 3.7+ (all versions above minimum supported)

Troubleshooting

Node Not Appearing

• Ensure the folder is in the correct custom_nodes directory
• Restart ComfyUI completely
• Check the console for any error messages

Incorrect Splitting

• Verify your separator string is correct
• For regex patterns, ensure they start and end with /
• Check that num_splits is set to the desired number

Empty Outputs

• Ensure your input text contains the separator
• Check that remove_empty is not removing valid content
• Verify num_splits is not set higher than the number of parts
