ComfyUI Node: String Function 🧅

String Function 🧅:

The NegiTools_StringFunction node is designed to allow you to execute custom Python code that manipulates strings. This node is particularly useful for AI artists who need to perform specific text transformations or generate dynamic text content within their workflows. By providing a flexible and secure environment to run Python code, this node enables you to customize string operations without needing extensive programming knowledge. The main goal of this node is to offer a versatile tool for text manipulation, enhancing your creative projects with tailored string functions.

String Function 🧅 Input Parameters:

python_code

This parameter accepts a string of Python code that defines the operations to be performed on the input strings. The code should be written in a way that it returns a string result. For security reasons, the use of the import statement is prohibited. The default value is return "a text", and it supports multiline input to accommodate more complex code.

a

This optional parameter is a string input that can be used within your Python code. It allows you to pass additional text data that can be manipulated or combined with other inputs. The default value is an empty string.

b

Similar to parameter a, this optional string input provides another piece of text data that can be utilized in your custom Python code. The default value is an empty string.

c

This optional string input functions like parameters a and b, offering yet another text input for your Python code to process. The default value is an empty string.

String Function 🧅 Output Parameters:

STRING

The output of this node is a single string that results from the execution of your custom Python code. This output is the final transformed or generated text based on the logic you have defined in the python_code parameter. It is important for interpreting the result of your string manipulations and integrating it into subsequent nodes or processes.

String Function 🧅 Usage Tips:

• Ensure your Python code is free of import statements to avoid security issues and errors.
• Use the optional parameters a, b, and c to pass different pieces of text data into your code, allowing for more dynamic and flexible string manipulations.
• Test your Python code in a separate environment before using it in the node to ensure it produces the desired output without errors.

String Function 🧅 Common Errors and Solutions:

"ValueError: "import" cannot be included in python_code for security reasons"

• Explanation: This error occurs when the python_code parameter contains an import statement, which is not allowed for security reasons.
• Solution: Remove any import statements from your Python code and use only the built-in functions and libraries provided by the node.

"SyntaxError: invalid syntax"

• Explanation: This error indicates that there is a syntax error in your Python code.
• Solution: Review your Python code for any syntax mistakes, such as missing colons, parentheses, or incorrect indentation, and correct them.

"NameError: name '_a' is not defined"

• Explanation: This error occurs when the code references a variable that has not been defined or passed as an input.
• Solution: Ensure that all variables used in your Python code are either defined within the code or passed as input parameters a, b, or c.

"TypeError: 'NoneType' object is not subscriptable"

• Explanation: This error happens when your code tries to perform an operation on a None value, which is not allowed.
• Solution: Check your code to ensure that all variables and operations are properly defined and that no None values are being used inappropriately.
