Added because it was in Fooocus, but I never use it. Implementation was simple with itertools:

import re
from itertools import product

def parse_prompt_with_arrays(prompt: str) -> list[str]:
    arrays = re.findall(r"\[\[(.*?)\]\]", prompt)

    if not arrays:
        return [prompt]

    tokens = [item.split(",") for item in arrays]  # [("a", "b"), ("1", "2")]
    combinations = list(product(*tokens))  # [("a", "1"), ("a", "2"), ("b", "1"), ("b", "2")]

    prompts = []
    for combo in combinations:
        current_prompt = prompt
        for i, token in enumerate(combo):
            current_prompt = current_prompt.replace(f"[[{arrays[i]}]]", token.strip(), 1)
        prompts.append(current_prompt)
    return prompts
