Stable diffusion prompt generator extension

A prompt generator extension based on wildcards and dynamic prompts

based on: https://github.com/jtkelm2/stable-diffusion-webui-1/blob/master/scripts/wildcards.py and https://github.com/adieyal/sd-dynamic-prompting

This version iterates on both these concepts by merging them and allowing for recursive wildcards

Wildcards work as expected where __clothes_full__ gets replaced by 1 line from the wildcards\clothes_full.txt file. The difference is however that each wildcard file can load other wildcard files with the same syntax.

Dynamic prompts are slightly different and do not support the $$ syntax to select multiple options from a list. It does however allows you to choose the percentage change an option gets chosen. ex: {25% a |25%b|c} will select a 25% of the time b 25% of the time and c 50% of the time.

These options can be nested with wildcards containing dynamic prompts and dynamic prompts containing wildcards both work.

Install

Either download this as a zip and extract it in the extensions directory located in your automatic1111's web ui. Or do a git checkout https://github.com/h-a-te/prompt_generator.git while in the extensions directory. After install restart your web ui and you will see 2 new options on your txt2img tab.

Configuration

The prompt generation allows you to specify configurable wildcards by adding them to the configuration.txt file. As an example in this repo breast sizes are configurable: This makes it easy to switch between different styles or prompts defined in the wildcard files.

To update what items are selectable add it to the configuration.txt file and reload scripts and ui from the settings menu

Use same prompt for each image

When checked the script will generate the same prompts for all your images instead of a random one for each.

Generate negative tags

When checked if a wildcard contains a tag surrounded by **tag** it will be added to the negative prompt

Adding wildcards

Wildcards can be added as .txt files in the wildcards directory and then used with __filename__.

Template syntax

Dynamic prompts

Using this script, the prompt:

A {house|apartment|lodge|cottage} in {summer|winter|autumn|spring} by {artist1|artist2|artist3}

Will generate any of the following prompts:

• A house in summer by artist1
• A lodge in autumn by artist3
• A cottage in winter by artist2
• ...

Weighting prompt options

The scripts allows you to weigh one or multiple options more / less heavily than others

A {75%house|apartment|lodge|}

will select house 75% of the time, and the other options 12.5% of the time. percentages can be given per options like so:

A {10%house|20%apartment|lodge}

Will select house 10% of the time apartment 20% of the time and lodge 70% of the time.

Wildcards

Wildcards look like the following:

__file__

this will try to read the file in the wildcards directory

__directory\file__

will read the file from wildcards\directory. Multiple nested directories are supported for organisation

Combining

Combining the 2 options is as simple as:

{25%__houses__|__apartments__}

This will select from the houses wildcard 25% of the time and apartments 75% of the time
