|
|
"""
|
|
The PromptPostProcessor class is responsible for processing and manipulating prompt strings.
|
|
|
|
The format for the negative tags is:
|
|
<!content!>
|
|
|
|
<!!x!content!>
|
|
|
|
with x being:
|
|
s - content is added at the start of the negative prompt. This is the default if no parameter exists.
|
|
e - content is added at the end of the negative prompt.
|
|
pN - content is added where the insertion point N is in the negative prompt or at the start if it does not exist. N can be 0 to 9.
|
|
iN - tags the position of insertion point N. Used only in the negative prompt and does not accept content. N can be 0 to 9.
|
|
|
|
Attributes:
|
|
NAME (str): The name of the prompt post-processor.
|
|
VERSION (str): The version of the prompt post-processor.
|
|
DEFAULT_STN_SEPARATOR (str): The default separator used for content sent to the negative prompt.
|
|
|
|
Methods:
|
|
__init__(self, script, opts=None, is_i2i=False): Initializes the PromptPostProcessor instance.
|
|
formatOutput(self, text: str) -> str: Formats the output text by encoding and decoding it.
|
|
STNTree: A nested class for interpreting and processing a tree generated by the prompt parser.
|
|
__find_tags(self, prompt): Finds tags in the given prompt and returns the modified prompt and tag information.
|
|
__add_to_insertion_points(self, negative_prompt, add_at_insertion_point): Adds the negative prompt to the insertion points.
|
|
__add_to_start(self, negative_prompt, add_at_start): Adds the elements in `add_at_start` list to the start of the `negative_prompt` string.
|
|
__add_to_end(self, negative_prompt, add_at_end): Adds the elements in `add_at_end` list to the end of `negative_prompt` string.
|
|
CleanupTree: A nested class for cleaning up a prompt parsed into a tree.
|
|
__cleanup(self, prompt, negative_prompt): Cleans up the prompt and negative prompt by removing extra spaces, empty constructs, and extra separators.
|
|
cleanup_text(self, text): Cleans up the given text by removing extra separators, breaks, and spaces.
|
|
trim_text(self, text): Trims the given text based on the specified cleanup options.
|
|
process_prompt(self, original_prompt, original_negative_prompt): Process the prompt and negative prompt by moving content to the negative prompt, and cleaning up.
