📝 Walkthrough

Walkthrough

This PR adds SaveTextNode (writes text to .txt/.md/.json, parsing and pretty-printing JSON with a fallback on parse error) and exposes it via TextExtension and comfy_entrypoint. The nodes_text.py module is added to the built-in extras_files list so the extension is loaded during startup.

We need to actually return enough information to be able to generate an asset based on the file that was generated. Otherwise, this node won't be able to work on Comfy Cloud. It also wouldn't appear correctly on the left side panel (for local or Cloud).
The PreviewText exists exactly for that -- to preview text. It isn't sufficient to actually create an output.

I have updated the code to include SavedResult in "files". Do you have a specific way in mind for implementing this or for the naming?

    return io.NodeOutput(
        ui={
            "text": (text,),
            "files": [
                ui.SavedResult(file, subfolder, io.FolderType.output)
            ]
        }
    )
