Simple Notepad++ language file for LC-3 assembly code

LC3 on NPP (An LC-3 Simulator language file for Notepad++)

About

This is a user-defined language file that can be loaded into Notepad++ to make LC-3 assembly code easier to read, write, and understand. I put this together while working through a computer organization course, and it helped me enough that I thought I'd share. I wanted it to sort of mimic NPP's included assembly style, so I've given it the following rules:

• Instructions are blue.
  • Underlined instructions set the condition code.
  • Italicized instructions use a program counter offset.
  • Underlined and italicized instructions do both.
• TRAP instructions are light blue.
• Pseudo-ops are brown.
• Registers are red.
• Numbers (decimal, hex, and binary) are gold.
• Comments are green.
