ComfyUI Node: textConcat

textConcat:

The ttN concat node is designed to concatenate up to three strings into a single string, with an optional delimiter to separate the concatenated parts. This node is particularly useful for AI artists who need to combine multiple text inputs into a cohesive output, such as combining prompts or descriptions. By providing a simple yet flexible way to merge text, the ttN concat node enhances the efficiency and creativity of your text-based workflows. The node ensures that undefined inputs are treated as empty strings, and it supports newline characters as delimiters, making it versatile for various text concatenation needs.

textConcat Input Parameters:

text1

This parameter represents the first string to be concatenated. It supports multiline input and dynamic prompts, allowing you to input complex or lengthy text. If the value is 'undefined', it will be treated as an empty string. The default value is an empty string.

text2

This parameter represents the second string to be concatenated. Similar to text1, it supports multiline input and dynamic prompts. If the value is 'undefined', it will be treated as an empty string. The default value is an empty string.

text3

This parameter represents the third string to be concatenated. It also supports multiline input and dynamic prompts. If the value is 'undefined', it will be treated as an empty string. The default value is an empty string.

delimiter

This parameter specifies the string that will be used to separate the concatenated parts. It does not support multiline input. If the delimiter is set to '\n', it will be interpreted as a newline character. The default value is a comma (,).

textConcat Output Parameters:

concat

This output parameter is the final concatenated string, created by joining text1, text2, and text3 with the specified delimiter. It provides a single, cohesive string that combines all the input texts according to the specified delimiter.

textConcat Usage Tips:

• Use the delimiter parameter to customize how the strings are separated. For example, use a space ( ) for a simple concatenation or a newline character (\\n) for multi-line text.
• Ensure that your input texts (text1, text2, text3) are not 'undefined' to avoid unexpected empty strings in the output.
• Utilize the dynamic prompts feature to create more complex and context-aware concatenations.

textConcat Common Errors and Solutions:

Unexpected empty strings in the output

• Explanation: This occurs when one or more of the input texts (text1, text2, text3) are 'undefined'.
• Solution: Ensure that all input parameters are defined and not set to 'undefined'. If an input is not needed, explicitly set it to an empty string.

Delimiter not working as expected

• Explanation: This can happen if the delimiter is not correctly specified, especially when using special characters like newline (\\n).
• Solution: Double-check the delimiter parameter to ensure it is correctly set. For newline characters, use \\n to represent a new line.

Concatenated output is not as expected

• Explanation: This might occur if the input texts contain unexpected characters or formatting.
• Solution: Review the input texts for any unintended characters or formatting issues. Adjust the inputs as necessary to achieve the desired output.
