Gartner Hover Card

Rest the mouse on a node in Nuke's Node Graph and a small card shows what you need to know about it, without opening anything.

Warnings first: errors, missing file on the current frame, disabled
Per node type:
- Read: colorspace, frame range on disk, file
- Write: output, folder, file type, colorspace
- Merge: operation, and which nodes feed A and B
- Group / gizmo: nodes inside, gizmo file
Image info: resolution, frames, layers, bbox (when bigger than the format), premult, cook time (when profiling is on), downstream node count
Changed: every knob you changed from its default, with its value
Pipes: rest on a pipe to see where it comes from, goes to, and which input
Backdrops: rest on the title strip to see the label and nodes inside

Nothing in your script is changed. It's one Python file with no dependencies.

Install

Copy gartner_hover_card.py into your .nuke folder (C:\Users\<you>\.nuke on Windows, ~/.nuke on macOS and Linux), or any folder on your NUKE_PATH.
Add this line to the menu.py in that folder (create the file if it doesn't exist):
```
import gartner_hover_card
```
Restart Nuke.

Turn it on or off from Gartner > Hover Card On - Off.

Edit the Settings class at the top of gartner_hover_card.py:

Setting	Default	What it does
`delay`	`0.5`	Seconds the mouse rests on a node before the card appears
`accent`	`#f5c518`	Accent colour of the card
`card_max_changed`	`8`	How many changed knobs to list
`pipe_info`	`True`	Show cards for pipes too
`view_scale`	`1.0`	Only change this if the card picks the wrong node

Tested with Nuke 16 on Windows. Older Nuke versions (PySide2) may need small adjustments, especially if the card appears for the wrong node.
