📝🪡AGSoft Text Concatenate

Every prompt-builder workflow ends up gluing strings together, and the naive text + "," + text approach has a nasty habit: leave one field empty and you get "masterpiece, , highly detailed" - stray commas and double spaces that quietly pollute your conditioning. 📝🪡AGSoft Text Concatenate is the pack's flexible string-joiner that handles that by default: it cleans whitespace, skips empty strings, and only inserts the delimiter between the strings that actually exist. It manages 2 to 32 inputs dynamically, so it grows with your workflow instead of forcing you to guess a fixed count.

How it works

It's the big brother of the pack's fixed X2/X4/X8 concatenates. The inputs are created dynamically by frontend JS based on number_of_inputs (2–32) - set it to 7 and you get text_1 through text_7, no dead sockets. The execution pipeline is where the quality lives:

1. clean_whitespace (default on) - strips leading/trailing whitespace from each input.
2. ignore_empty_strings (default on) - drops anything empty or whitespace-only.
3. delimiter - the separator, chosen from 15 presets (",", "New Line", "Space", " | ", and more) or "custom" for your own.
4. custom_delimiter - the free-text field, active only when delimiter is "custom". Supports escape sequences: \n (newline), \t (tab), \r.
5. reverse_order (default off) - flips the join order (last input first). Handy when a downstream node reads prompts newest-first.

The output is a single STRING - the joined result.

What you'll actually set

• number_of_inputs - grow the field count to match your prompt parts.
• delimiter - this is the one you'll touch constantly. ", " is what most people want for prompt fragments; "New Line" if you're building a multi-paragraph structure. The " - " and " :: " presets are aimed at tag-style joins.
• ignore_empty_strings - leave on. Turn it off only if you want empty entries represented (e.g. you're joining for CSV-style output and need positional slots).

Installing and gotchas

cd ComfyUI/custom_nodes
git clone https://github.com/Art-xmaster/comfyui-AGSoft

Restart, or ComfyUI Manager → "comfyui-AGSoft". No models.

The one trap: because custom delimiters go through escape processing, a literal \n in your custom field becomes a newline - which is what you want 99% of the time, but if you ever need a literal backslash-n in the output you'll have to double it. And remember this is the dynamic variant: if you know you'll always join exactly 4 strings, the fixed X4 is the tidier, less-widget-y choice. Use the dynamic one when the count changes between workflows.
