# 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

- [x] Move the bulk of cpu.js to cpu.lib.js
- [x] Add a way to register functions to be called each cycle
- [x] Create a new 'cardiograph.js'
    - [x] 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

## TODO

- ?
    - Move notes, issues to their own branches
    - Make worktrees for those branches
    - NB: VS Code's git management tools work fine with worktree folders if you open them in a new window -- but opening them in a workspace doesn't work
