Text Show Multiline Color

ComfyUI has a dozen ways to show text, and most of them blank out the moment the workflow reruns or the graph reloads. Text Show Multiline Color, from the illumorae pack (CorvaeOboro's text-utility corner), is the one that actually persists: it renders multiline text as syntax-highlighted, selectable, copyable content in a widget that keeps its state across reloads, and it still passes the plain string through as an output. It's the node you put at the end of a text pipeline when you want to read what's flowing through.

What's the syntax highlighting for? Real IDE behavior, aimed at prompts: parentheses colored by nesting depth, square and curly brackets, numbers, <lora:...> and <embedding:...> tags, quoted strings, #/// comments, and commas. If you've ever stared at ((masterpiece)) and wondered whether your parentheses actually balance, the depth-based coloring answers it at a glance. That's genuinely useful for enclosure-heavy prompts, and it plays nicely with the pack's other text nodes - reorder something, truncate it, and dump it here to eyeball the result.

Inputs and what it tolerates

Three inputs: text (multiline), enable_highlighting (default on - turn it off for a clean plain view), and theme (dark/light). Output is text as a plain STRING, so it slots into anything downstream without the HTML ever leaking through - the color lives only in the widget.

The robustness is the underrated feature: the node was written to gracefully handle None, dicts, lists, and bypassed upstream nodes instead of throwing. If an upstream node died or returned something weird, this one shows you an error message rather than taking the whole graph down with it. For debugging a long pipeline that generates strings, that alone is worth the install.

Installing it

ComfyUI Manager → search "illumorae" → install, or:

cd ComfyUI/custom_nodes
git clone https://github.com/CorvaeOboro/ComfyUI_illumorae

Restart. No models, no dependencies beyond ComfyUI's own stack.

Troubleshooting

If the highlight colors don't appear, check enable_highlighting is on and your frontend is current - the rendering is a JS widget, so ancient ComfyUI versions won't show it. If the node shows an error-style block instead of text, that's the graceful-failure path doing its job: look at what you fed it, because the string was malformed or missing, not because the node broke. A display node through and through - it won't fix your text, but it'll finally show you what it actually is.
