String Join Multi - Join Multiple Text Blocks

Node Purpose: String Join Multi accepts up to 5 text blocks, supports {input} substitution, comment filtering, and empty-line control, then joins them using a separator. Separator supports escape sequences and composite forms like \n---\n.

Inputs

Name	Port	Type	Default	Range	Description
text1	-	STRING	""	-	Text block 1, multiline supported.
text2	-	STRING	""	-	Text block 2, multiline supported.
text3	-	STRING	""	-	Text block 3, multiline supported.
text4	-	STRING	""	-	Text block 4, multiline supported.
text5	-	STRING	""	-	Text block 5, multiline supported.
filter_empty_line	-	BOOLEAN	false	-	Remove empty lines.
filter_comment	-	BOOLEAN	false	-	Filter comments (# and triple-quote blocks).
separator	-	STRING	"\n"	supports \n / \t / \r / \\ combos	Join separator; composite like \n---\n works.
input	-	STRING	""	-	String to replace {input} placeholders.

Outputs

Name	Type	Description
string	STRING	Joined result string.

Features

• Per-block processing: placeholder substitution and comment/empty-line filtering per block; empty results are skipped.
• Separator escaping: supports \n, \t, \r, \\ and composite strings (e.g., \n---\n).
• Template injection: consistent {input} substitution across blocks.

Typical Usage

• Consolidate multiple prompt sections into a single output with visual separators (separator=\n---\n).
• Clean blocks (remove comments and empty lines) before joining for a tidy context.

Notes & Tips

• Only non-empty processed blocks participate in the final join; to preserve empty blocks, set filter_empty_line=false.
• Triple-quote blocks must be properly closed; for advanced filtering, combine with String Filter.
