ComfyUI Vivid Prompt Analysis Replacement

A lightweight ComfyUI custom node package that exposes the PromptReplaceParserNode node for structured Chinese prompt parsing and override merging.

What It Does

This node accepts:

• source_text: base prompt text in one of these formats:
  • JSON string
  • Python dict-like string
  • labeled text using 目标/保留/迁移/环境/光影/细节/输出/类型选择
• override_text: partial override text using the same labeled format

It outputs:

• prompt_list
• prompt_text
• style_text

Node Behavior

The node preserves the current behavior from the original implementation:

• Parses source_text using json.loads, ast.literal_eval, then labeled text fallback
• Parses override_text from dict input or labeled text
• Uses override values only when they contain meaningful Chinese content
• Appends sentence punctuation when needed
• Removes whitespace from each final output line
• Returns merged prompt lines, joined prompt text, and style text
