A standalone ComfyUI node pack for selecting one item from a list by index and converting an ETK LIST value into a native ComfyUI list-mapped output.

The pack preserves the historical workflow class IDs, input socket names, output order, categories, and selection behavior previously supplied by EternalKernelLiteGraphNodes and SWAIN. Existing workflows do not need node replacement or rewiring.

ETKListToComfyList (List To ComfyUI List)

List To ComfyUI List returns the contained items through ComfyUI's native list-output contract. A downstream node that does not use INPUT_IS_LIST is therefore executed once for every item, instead of receiving one Python list object.

Install

Install the immutable Registry release with Comfy CLI:

comfy node install etk-from-list-index@1.1.0

New Registry releases have a short pending security-scan window. During that window the exact version remains installable, but the @latest alias is not added to ComfyUI-Manager's active CNR index yet.

Alternatively, clone the public repository into ComfyUI's custom_nodes directory and restart ComfyUI:

git clone https://git.hoppingmadgames.com/hmg-comfy/ComfyUI_ETK_From_List_Index.git

Compatibility

The node class IDs intentionally match the legacy definitions. Installing this pack makes it the standalone implementation owner; serialized workflows keep using the same class IDs.

Release Verification

Every release must pass the exact anonymous recursive clone shape used by ComfyUI Manager:

python3 tools/verify_manager_install.py --source .

Registry publishing is supported only through the gated wrapper, which reads the API key from standard input and never puts it in process arguments or the environment:

python3 -m tools.publish_registry_release \
  --changelog "Describe this release"
