string hub 文本集中输入框

Large workflows die of clutter - nine text nodes scattered across the canvas, each with a prompt buried in its widget, none of them findable. StringHub9 (2lab) is the answer: one node with nine multiline text fields that all feed different parts of your graph. The Chinese subtitle says it plainly: 文本集中输入框, the "centralized text input box." It's a control panel for all the strings your workflow needs, in a single place.

This is the classic "hub" pattern that power packs like rgthree popularized - centralize the stuff you edit every run so you don't hunt through the graph. Here the inputs are intentionally generic: string1 through string9, each a multiline box, each with its own output. Prompt, negative prompt, seed comment, style tag, output filename - put all of them here and your canvas gets dramatically quieter.

Inputs that matter

• string1 … string9 - nine multiline text fields, each output individually. The core of the node.
• base_string - a shared string you can join onto the others.
• separator - what goes between base_string and the individual strings when joining (default is a comma).
• concat - the join mode: Before (prepend base_string), After (append it), or None (off by default). With None, the nine strings pass through untouched and base_string/separator do nothing.

Outputs

Nine STRING outputs, string1 through string9, mirroring the inputs. Wire each to wherever that string is consumed - usually a CLIP text encoder or a node that needs a label.

How it works

At heart it's a routing node: nine strings in, nine strings out, no transformation unless you turn on concat. When you do, the shared base_string gets joined to each string with the separator - handy for stamping a common suffix or prefix onto every prompt in one move, like appending a style tag to all nine inputs. That's a small but real workflow shortcut: one edit to base_string updates every branch.

Installing it

Same install as the rest of the pack. ComfyUI Manager → search "comfyUI-tool-2lab" → install, or:

cd ComfyUI/custom_nodes
git clone https://github.com/AI2lab/comfyUI-tool-2lab

Restart ComfyUI. Pure Python, no models.

Gotchas

• concat defaults to None. Most people assume the hub concatenates by default and get confused when nothing joins. It only joins when you explicitly pick Before or After.
• Empty strings still occupy a slot. You don't have to fill all nine, but an empty one still emits an empty string - fine unless whatever's downstream chokes on empties.
• Repo visibility. The pack's GitHub page currently returns 404, likely because the author made it private or moved it. Fresh installs can fail while existing ones keep working - don't blame your steps.
