Oh Zillow.

Why are gammons so bothered about a biscuit's genitals?

What is the point of this!?

Dynamic Prompt is a script that you can use on AUTOMATIC1111 WebUI to make better, more variable prompts. In this guide I will explain how to use it.
Combinations

{2$$opt1opt2opt3} 

This will randomly combine two of the options for every batch, separated with a comma. In this case, "opt1, opt2" or "opt2, opt3", or "opt1, opt3" or the same pairs in the reverse order.

{1-3$$opt1opt2opt3} 

This will use a random number of options between 1 and 3 for each batch.

{opt1opt2opt3} 

If you omit the $$ prefix, one item will be selected. (Equivalent to 1$$)

Wildcard files

Wildcard files are not provided by this script as lists exists in other repositories. A good place to start looking is here Empty lines and lines starting with # are ignored. This can be used to add comments or disable sections of the file.

Nesting

You can nest combinations inside wildcards. This means that you can create more advanced templates. For example:

{__seasons____timeofday__} 

This will then either choose a season from seasons.txt or a time of day from timeofday.txt.

Recursion

Prompts are processed recursively. If a wildcard file contains a row with dynamic syntax, then that will be resolved as well. For example if seasons.txt contains the following rows:

Summer Winter {AutumnFall} Spring 

if the 3rd row is chosen, then either Autumn or Fall will be selected. You could go pretty wild e.g.

Summer __winter_in_different_languages__ {AutumnFall} Spring 

Fuzzy Glob/recursive wildcard file/directory matching

In addition to standard wildcard tokens such as __times__ -> times.txt , you can also use globbing to match against multiple files at once. For instance:
__colors*__ will match any of the following:

• WILDCARD_DIcolors.txt
• WILDCARD_DIcolors1.txt
• WILDCARD_DInested/foldecolors1.txt

__light/**/*__ will match:

• WILDCARD_DInested/foldelight/a.txt
• WILDCARD_DInested/foldelight/b.txt

but won't match

• WILDCARD_DInested/foldedark/a.txt
• WILDCARD_DIa.txt

You can also used character ranges [0-9] and [a-z] and single wildcard characters ? . For more examples see this article.

Combinatorial Generation

Instead of generating random prompts from a template, combinatorial generation produced every possible prompt from the given string. For example: I {lovehate} {New YorkChicago} in {JuneJulyAugust}
will produce:

• I love New York in June
• I love New York in July
• I love New York in August
• I love Chicago in June
• I love Chicago in July
• I love Chicago in August
• I hate New York in June
• I hate New York in July
• I hate New York in August
• I hate Chicago in June
• I hate Chicago in July
• I hate Chicago in August

If a __wildcard__ is provided, then a new prompt will be produced for every value in the wildcard file. For example: My favourite season is __seasons__
will produce:

• My favourite season is Summer
• My favourite season is August
• My favourite season is Winter
• My favourite season is Sprint

You also arbitrarily nest combinations inside wildcards and wildcards in combinations.
Combinatorial generation can be useful if you want to create an image for every artist in a file. It can be enabled by checking the Combinatorial generation checkbox in the ui. Note, num batches changes meaning. With random generation, exactly num_batches * batch_size images are created. With combinatorial generation, at most num_batches * batch_size images are created. This upper limit ensures that you don't accidentially create a template that unexpectedly produces thousands of images.
Combinations are not yet supported, i.e. {2$$abc} will treat 2$$a as one of the options instead of selecting two of a, b and c.
The combinatorial batches slider lets you repeat the same set of prompts a number of times with different seeds. The default number of batches is 1.

Fixed seed

Select this if you want to use the same seed for every generated image. If there are no wildcards then all the images will be identical. It is useful if you want to test the effect of a particular modifier.

Magic Prompt

Using Gustavosta's MagicPrompt model, automatically generate neww prompts from the input. Trained on 80,000 prompts from Lexica.art, it can help give you interesting new prompts on a given subject. Here are some automatically generated variations for "dogs playing football":

dogs playing football, in the streets of a japanese town at night, with people watching in wonder, in the style of studio ghibli and makoto shinkai, highly detailed digital art, trending on artstation
dogs playing football, in the background is a nuclear explosion. photorealism. hq. hyper. realistic. 4 k. award winning.
dogs playing football, in the background is a nuclear explosion. photorealistic. realism. 4 k wideshot. cinematic. unreal engine. artgerm. marc simonetti. jc leyendecker

This is compatible with the wildcard syntax described above.
The first time you use it, the model is downloaded. It is approximately 500mb and so will take some time depending on how fast your connection is. It will also take a few seconds on first activation as the model is loaded into memory. Note, if you're low in VRAM, you might get a Cuda error. My GPU uses less than 8GB by YMMV.

Collections

The collections directory contains modifier libraries that you can use as is or use to bootstrap your own. Copy the collection that you want to use into the wildcards directory. Note, in previous versions, the collections were in the wildcards directory. This has now changed so that your own collections don't get clobbered every time you want to update the extension.
If you're using a Unix/Linux O/S, you can easily create a symlink to the relevant collection rather than copying it across if you don't plan to alter it. E.g.

ln -sr collections/parrotzone wildcards/ 

WILDCARD_DIR

The script looks for wildcard files in WILDCARD_DIR. This is defined in the main webui config.json under wildcard_dir. If wildcard_dir is missing, then wildcard files should be placed in scripts/wildcards/
