Josia文本列表

JosiaTextList (Josia文本列表) does one boring, essential thing: it takes a multiline blob of text and splits it into a proper list, one entry per line. That sounds trivial until you're feeding an LLM-generated batch of prompts into a workflow and realize ComfyUI's string plumbing doesn't give you a clean "list of strings" for free. This node is the adapter.

The classic use case: an LLM returns twenty numbered prompt variants. You paste them in, and you want each one processed separately. Connect this node to a batch-capable downstream node and the list output fans out into individual items. The README also suggests it for splitting path lists and config text, and for cleaning up LLM output - those [prompt 1], [prompt 2] headers are exactly the kind of garbage the regex filter was built to strip.

The settings that matter

Only the first input, text, is required - a multiline string, ideally wired from an upstream text node. Everything else is optional polish:

• 过滤空行 (filter empty lines) - default on. Drops blank lines after splitting.
• 修剪空白 (trim whitespace) - default on. Strips leading/trailing spaces and tabs per line.
• 分隔符 (delimiter) - default \n (newline). You can split on \t, commas, semicolons, anything. Leave it blank and the node doesn't split at all - the whole text becomes a single entry, which is handy when you want to use it as a plain text box.
• 去重过滤 (dedup) - default off. Removes duplicate lines, preserving order.
• 正则过滤 (regex filter) - the power tool. It comes with a set of built-in quick rules like /汉字/ (keep lines containing Chinese), /英文/ (containing English), /数字/ (containing digits), /序号行/ (numbered lines), /标签行/ (tag lines starting with [), plus a /?文本/ wildcard match - /天空/ keeps only lines containing "sky". Combine them with | if you need "English OR numbered".

The output

One output, prompt_list (STRING, a list type). Downstream nodes that support list expansion will run once per entry - wire it to a text-encoder or an image generator with batch support and one queue does all N prompts. The node also shows a live preview of the split result below it, which saves you a lot of "why is this line in my prompt" staring.

Install

This one is pure Python standard library - the README specifically calls out that it keeps working even if the pack's web/js frontend files are lost. Zero extra dependencies, part of ComfyUI_JosiaNodes:

cd ComfyUI/custom_nodes
git clone https://github.com/Josia-doit/ComfyUI_JosiaNodes

or via ComfyUI Manager (search ComfyUI_JosiaNodes), then restart. It's under the Josia category.

Honest notes

The regex filter is genuinely useful but reads like a text file got glued onto a node - the built-in rules use the Chinese labels, so if you're not comfortable with Chinese you'll want the README's translation table open the first time. And remember the blank-delimiter trick: if all you wanted was a display box for arbitrary text, leaving 分隔符 empty turns it into exactly that. Not every workflow needs this node, but the moment you're batch-processing prompts, you'll be glad it's cheap to add.
