StringConditionalAppend

Conditionally adds strings to the input text only if they're not already present. Useful for ensuring specific keywords or phrases exist in prompts without creating duplicates. Enter multiple strings (one per line) to check and append any that are missing. - inputstring: The string or text to process (connection input) - stringstocheck: List of strings to search for and append if not found (one per line) - position: Where to add strings if not found (end or beginning) - matchcase: Enable/disable case-sensitive search - separator: Character(s) to use between text and appended strings (default: , ) - outputstring: The resulting text (with or without appended strings) - wasappended: Boolean indicating whether any strings were added

StringContainsAny

Checks if the input string contains any of the specified substrings. Returns a boolean result and the first matched substring. Useful for conditional workflows, such as loading specific LoRAs based on prompt keywords (e.g., load anime LoRA if prompt contains "anime", "manga", or "cel-shaded"). - inputstring: The string or text to search within (connection input) - substrings: List of substrings to search for (one per line) - matchcase: Enable/disable case-sensitive search (default: disabled) - containsany: Boolean indicating whether any substring was found - matchedstring: The first substring that was found (empty string if none matched)

StringMultiReplace

Replaces text strings with new strings (replace/swap words etc.). Each line should contain a search and replace pair separated by the replacementdelimiter (default is double colon ::). Example to replace dog with cat dog::cat. Supports mulitple string replacements, just add one replacement per line. You can also remove strings with this node just leave the right side of the delimiter blank. - inputstring: The string or text to process - replacementpairs: List of search::replace pairs (one per line) - replacementdelimiter: Character(s) that separate search and replace strings (default: ::) - matchcase: Enable/disable case-sensitive matching - matchwholestring: Ensure only exact matches are replaced - preservepunctuation: Keep punctuation marks adjacent to matched text (default: enabled) - removeextraspaces: Clean up extra spaces after replacement - sortbylength: When enabled, longer search strings are replaced first to prevent substring clobbering. Disable to process pairs in input order, allowing intentional chaining (default: enabled) - useregex: When enabled, search strings are treated as regex patterns instead of literal text (default: disabled)

StringPreview

Simply displays a string output. Can be used to view the results/changes to the inputstring by the String Strip or String Replace.

StringStrip

Removes specified strings from input text. Each line should contain the string to be searched. The string can contain multiple words. To strip multiple individual words/strings place on separate lines. - inputstring: The string or text to process - stringstoremove: List of strings to remove (one per line) - matchcase: Enable/disable case-sensitive matching - matchwholestring: Ensure only exact matches are removed - preservepunctuation: Keep punctuation marks adjacent to matched text (default: enabled) - removeextraspaces: Clean up extra spaces after removal

StringTextbox

A simple multiline textbox for free form text.
