A TUI UOP file editor for CENG3420 (CUHK CSE) Lab 3. It makes your life a little bit easier.

You must have Node.js installed on your device, whether it is system-wide or nvm doesn't matter.
Run this command to install the package.

npm i -g ceng3420-lab3-helper

After installing the package globally with the previous command, a new uop-editor program should be available.

uop-editor <path> [-r <refpath>]

<path> is the path to the uop file you want to edit.
-r <refpath> is an optional argument to supply a reference uop file. This makes the "show X only" function also shows signals that are originally X but modified, saved and re-opened in another session.
