ComfyUI node to replace words in prompts

How it works

1. Persistence:

   • When you load a workflow.json, ComfyUI loads the rules saved inside that JSON.
   • When you add a new node, it reads default_rules.txt.
   • If you update default_rules.txt later, your old workflows remain exactly as they were (because the rules are saved in the workflow file), satisfying your requirement.

2. Validation:

   • When you type in the "Rules" box, the JavaScript validateRules function checks every line.
   • If you type badword (no colon) and hit Enter, the box background turns Red.
   • If you fix it to badword:goodword, the background turns back to normal.

3. Installation:

   • Just put the folder in custom_nodes.
   • Restart ComfyUI (ComfyUI automatically finds .js files inside subfolders of custom_nodes).

The Default Rules File

The default_rules.txt acts as the default source of word replacement rules for new nodes.

# These are the default replacement rules
cat: dog
blue: red
happy: ecstatic
old: new
