🌀 BV Pipe Nodes (ComfyUI)

This node pack introduces a config-driven “pipe” concept for ComfyUI. A pipe is a single connection that can carry up to 100 values (any type), identified by user-defined names.

The goal is to keep graphs clean: instead of wiring many individual lines, you can pass a single pipe and still access named slots.

Included Nodes

🌀 BV Pipe Config

Node key: BV Pipe Config Creates a new pipe configuration (slot names).

Inputs

• names (STRING, multiline) One slot name per line.
  • Empty lines are ignored
  • Commas are treated like new lines
  • Max: 100 names

Outputs

• pipe (BV_PIPE) A pipe object containing:
  • _cfg.names_raw (original text)
  • _cfg.names (parsed list of names)
  • items (values list)
  • map (name → value)

Notes

• The number of active slots equals the number of non-empty lines in names.

🌀 BV Pipe

Node key: BV Pipe Category: 🌀 BV Node Pack/pipe

A dynamic “carrier” node that provides:

• pipe input/output (forwarded)
• up to 100 optional inputs (v_001 … v_100)
• up to 100 outputs (out_001 … out_100)

The UI is driven by the connected pipe config:

• Only as many slots as configured are shown.
• Slot labels are taken from BV Pipe Config lines.

Inputs

• pipe (BV_PIPE) The incoming pipe.
• v_001 … v_100 (ANY, optional) Optional overrides for the corresponding slot.

Outputs

• pipe (BV_PIPE) Updated pipe containing final values.
• out_001 … out_100 (ANY) Mirrors the final resolved values.

Behavior Details

Slot naming / labels

• Internal socket names stay stable:
  • Inputs: v_001 … v_100
  • Outputs: out_001 … out_100
• Only the visible label changes to your configured names.
• This keeps ComfyUI validation stable and preserves “optional input” behavior.

Passthrough logic

For each configured slot i:

• If the input v_### is connected/provided → it overrides the value.
• Otherwise the node passes through the value from the upstream pipe (pipe.items[i]).

This makes chaining pipes possible:

BV Pipe Config → BV Pipe → BV Pipe → ...

The values continue downstream unless explicitly overridden.

Collapsed by default (optional UI behavior)

If you implemented the “collapsed new node” behavior in JS:

• A newly created BV Pipe node starts with only pipe in/out visible.
• Once a pipe config is connected, it expands to the configured slots.

Recommended Usage

1) Create a configuration

1. Add 🌀 BV Pipe Config
2. Enter slot names, one per line, e.g.
