JoinStringMulti (suggestion)

[jtc-jtc]

I have been finding the JoinStringMulti very useful in a couple of workflows, but using '\n' delimiter doesn't seem to add a line break at the end of each string as with other similar nodes. is there a workaround to add this function to the node?

Can you give an example of a node where it does work?

was-node-suite 'text concatenate' node seems to work correctly using \n but it doesn't have the great input count option as yours does!

I managed to get it working by adding a bit of code to your 'nodes.py' file from an LLM response (sorry I'm not a coder so no idea of its quality). It also adds a section to ignore null inputs which is handy if some of the input strings are bypassed/muted. I will paste the class section below -

class JoinStringMulti:
    @classmethod
    def INPUT_TYPES(cls):
        return {
            "required": {
                "inputcount": ("INT", {"default": 2, "min": 2, "max": 1000, "step": 1}),
                "string_1": ("STRING", {"default": '', "forceInput": True}),
                "string_2": ("STRING", {"default": '', "forceInput": True}),
                "delimiter": ("STRING", {"default": ' ', "multiline": False}),
                "return_list": ("BOOLEAN", {"default": False}),
            },
        }

    RETURN_TYPES = ("STRING",)
    RETURN_NAMES = ("string",)
    FUNCTION = "combine"
    CATEGORY = "KJNodes"
    DESCRIPTION = """
    Creates a single string or a list of strings from multiple input strings.
    You can set how many inputs the node has with **inputcount** and clicking update.
    """

    def combine(self, inputcount, delimiter, **kwargs):
        # Convert "\n" in delimiter to an actual newline character
        if delimiter == "\\n":
            delimiter = "\n"

        # Initialize the combined string with the first non-empty string
        string = kwargs.get("string_1", "")
        return_list = kwargs.get("return_list", False)
        strings = [] if string == "" else [string]  # Initialize list only if first string is non-empty

        # Loop through the remaining strings and add them if they are non-empty
        for c in range(1, inputcount):
            key = f"string_{c + 1}"
            new_string = kwargs.get(key, "")
            if new_string:  # Only add non-empty strings
                if return_list:
                    strings.append(new_string)
                else:
                    string += delimiter + new_string

        # Return the appropriate output based on return_list
        if return_list:
            return (strings,)  # Return the list of non-empty strings
        else:
            return (string,)  # Return the concatenated string
