String List Editor Ovum

String List Editor Ovum turns a multiline text box into a Python list object: type one string per line, and out flows a list - a single value on the wire, ready for other Python-list utilities to slice, join, index, or iterate. It's the maintained Python-list variant of the pack's string-editor family.

Which editor should you actually use?

The comfy-ovum pack ships three string-list editors, and the only real question is which dialect your downstream node speaks:

• StringBatchEditorOvum (ovum/lists/comfy) - output declared as a graph batch; the engine can fan it out to list-aware consumers.
• StringListEditorOvum (ovum/lists/python, this one) - output is a real Python list object as a single value, for list-utility consumers.
• StringListEditor (ovum/lists/any) - the original, marked deprecated in the source, superseded by the two above.

If you're feeding the pack's own list utilities - slices, splices, joins, index lookups, loops - this Python-list variant is the natural fit. If you're feeding a node that wants a batch it can iterate element-by-element, use the Batch variant.

How it works

Backend is the same split-and-trim logic as its siblings: split the multiline string on newlines, strip whitespace per line, drop blank lines, return the remaining strings as a list. The difference is purely the type declaration - no OUTPUT_IS_LIST flag, so the list stays a single opaque value rather than a graph batch.

Inputs and outputs

• items_text (required, STRING, multiline) - one item per line, blank lines ignored, whitespace trimmed.
• * (output) - the Python list of strings.

Installing it

Part of the comfy-ovum pack:

cd ComfyUI/custom_nodes
git clone https://github.com/sfinktah/comfy-ovum

Restart ComfyUI, or install via ComfyUI Manager → search "comfy-ovum". Light dependencies, no models.

Common gotchas

• The drag-and-drop UI lives elsewhere. The older StringListEditor documented file dropping and an Add button; the maintained variants are backend-simple. If the UI widget you're used to isn't showing up, check which variant you actually added.
• Same cleaning rules as the family. Leading/trailing spaces are trimmed and empty lines are dropped. Preserving exact whitespace? Wrong node.
• It's a single list value, not a batch. Feed it to something expecting to iterate individual inputs and you'll get the list-as-one-object behavior - pick the Batch variant for fan-out.
