Construct the formatted string from template and format-dictionary. — ComfyUI node from String Constructor (Text-Formatting). Run it in the cloud, no install…

Composing prompt variants from the same text pieces with ease:
• Build your "library" (dictionary) of named text chunks (sub-strings) to use it across the entire workflow.
• Compile these snippets into different prompts in-place - with just one string formatting node.
• Freely update the dictionary down the line - get different prompts.
• Reference text chunks within each other to build dependent hierarchies of less/more detailed descriptions.
• A real life-saver for regional prompting (aka area composition).

Construct the formatted string from template and format-dictionary.

Name	Type	Default	Description
template	STRING		Type the text template. To reference named substrings from format-dictionary, use this syntax: {substring_name}. For example: score_9, score_8_up, score_7_up, {char1_short}, standing next to {char2_short}, {char1_long} {char2_long}
recursive_format	BOOLEAN	false	Do recursive format - i.e., allow the chunks from the dictionary to reference other chunks.
safe_format	BOOLEAN	true	If template contains an invalid {text pattern} which can't be formatted - leave it as-is (instead of throwing an error). Safe mode is recommended for templates with JSON, CSS, or other literal curly brackets.
show_status	BOOLEAN	true	Show the final string constructed from the text-template and format-dictionary?
dictopt	DICT		The dictionary to take named sub-strings from. It could be left unconnected, if the pattern doesn't reference any sub-strings - then, this node acts exactly the same as a regular string-primitive node.
