Variables do not regenerate for each prompt

[spooji]

"Immediate evaluation" of variables using the ! as in ${season=!{summer|autumn|winter|spring}} results in all generations in a Batch Count to use the same value (i.e. 10 images using 'summer').

Without the !, the variable is evaluated every time the variable is mentioned in a prompt so there will be three random seasons in one prompt when ${season} is called three times.

I cannot find documentation which explains how to get the same value in throughout each generation and then reevaluate on the next generation (i.e. each of the 10 batch count only uses a single season for all instances of ${season} in that generation so image 1 might be summer whereas image 2 might be autumn).

Is this a bug or by design?

Same issue here

I did a workaround in ComfyUI using some find and replace magic. Unfortunately I had to add another find and replace thingy to remove the line breaks. But at least the variables keep being regenerated for each run.

Same problem for me, using Forge.

Having the same issue here,

Prompt example:

${color=!__color__}, 
$(color) shirt, $(color) pants, $(color) boots

Output: if batch set to 1:
red shirt, red pants, red boots

Output: if batch set to 1+:

red shirt, red pants, red boots
red shirt, red pants, red boots
red shirt, red pants, red boots

Output excepted set to 1+:

red shirt, red pants, red boots
blue shirt, blue pants, blue boots
green shirt, green pants, green boots

I've been hitting this for months now, and I finally decided to just stop using variables altogether. But that's not really a solution, and in cases where you need variables, you need variables.

Has anyone tried to rewrite the variable portion in JINJA? That's probably my next step if no one has.

FYI, this duplicates #642

Hi

For those who use comfyui, I found a way to modify a line in the nodes/sampler.py file.

Line 104 : return self._current_prompt != text
replace by return True

`

def has_prompt_changed(self, text: str) -> bool:
"""
Check if the prompt has changed.
"""
# return self._current_prompt != text
return True

`

Seems to works for me.
