Multi String Join - Ordered Join with Filtering and Placeholder

Node Purpose: Multi String Join joins multiple string inputs in numeric order using a configurable separator, with options to filter empty lines and comments, and to substitute {input} placeholders.

Inputs

Name	Port	Type	Default	Range	Description
filter_empty_line	-	BOOLEAN	False	-	Remove empty lines after processing.
filter_comment	-	BOOLEAN	False	-	Remove comments and triple-quoted blocks.
separator	-	STRING	\n	-	Join separator; supports escapes \n, \t, \r.
input	-	STRING	``	-	Value to substitute into {input} placeholders.
string_1	-	STRING	-	-	First string.
string_2…string_N	optional	STRING	-	-	Additional strings recognized by numeric suffix ordering.

Outputs

Name	Type	Description
string	STRING	Joined and filtered result.

Features

• Ordered collection: gathers string_* inputs by numeric suffix.
• Placeholder substitution: replaces {input} inside each string and final result.
• Comment filtering: removes # comments and respects '''/""" block quotes with stateful parsing.
• Empty-line filtering: optional removal after trimming.
• Separator decoding: interprets escape sequences for clean joins.

Typical Usage

• Prompt assembly: combine prompt fragments with placeholders for dynamic content.
• Config templating: join sections while stripping comments and blank lines.
• Ordered merging: ensure string_1..N join in intended sequence.

Notes & Tips

• Block-quote handling ensures multi-line quoted content is preserved when filtering comments.
• Provide separator="\n\n" for paragraph breaks, or ", " for comma-separated lists.
