String Constant Multiline

Documentation

• Class name: StringConstantMultiline
• Category: KJNodes/constants
• Output node: False

The StringConstantMultiline node is designed to process multiline string inputs, optionally stripping newline characters based on a boolean flag. It enables the manipulation of text data by allowing the preservation or removal of formatting, making it versatile for various text processing tasks.

Input types

Required

• string
  • The primary text input that the node processes. It accepts multiline strings, enabling the handling of text data that spans multiple lines.
  • Comfy dtype: STRING
  • Python dtype: str
• strip_newlines
  • A boolean flag that determines whether newline characters in the input string should be removed. When set to true, it strips newline characters, flattening the text to a single line.
  • Comfy dtype: BOOLEAN
  • Python dtype: bool

Output types

• string
  • Comfy dtype: STRING
  • Outputs the processed string, which may have newline characters removed based on the input flag. This allows for flexible text manipulation and formatting.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
