# Dev notes — 2023-08-28

Two current goals:

## 1. Implement a new CLI interface

- New arg-parser
- Allow setting clock speed with a command line flag


## 2. Re-architect

- Move the bulk of cpu.js to cpu.lib.js
- Add a way to register functions to be called each cycle
- Create a new 'cardiograph.js'
    - imports cpu.lib.js
    - registers functions for logging, updating display
        - (split those apart)
    - provides terminal interface
        - get machine code input from stdin (or like, file stream?)
        - `./assembler.js | ./cardiograph.js 
        - see below re: changes to assembler
- Assembler
    - Move CLI interface into assembler.js and delete run-assembler.js
    - Add a --json flag, which causes the assembler to print the json of {machineCode, debugInfo} on stdin
    - Otherwise, print hex/bin to stdin
