 Build Instructions

Tested on Ubuntu 20.04 LTS.

Tools setup:

  * Install rust: curl --proto '=https' --tlsv1.2 -sSf https://
    sh.rustup.rs | sh
  * Install wasm-pack: curl https://rustwasm.github.io/wasm-pack/
    installer/init.sh -sSf | sh
  * Install node through nvm:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
nvm install node

Clone this repository:

$ git clone https://github.com/abhaynayar/n2t-wasm

Building the emulator:

  * Run wasm-pack build in the root directory. This will create a new
    pkg/ directory for the wasm modules.
  * Run npm init wasm-app www in the root directory. This will
    generate a web page in a new www/ directory. See if you already
    have a www/ directory. If so, you don't need to do create one.
  * Run npm install in www directory to install the node modules.
  * Run npm run start in the www directory to start a local testing
    instance.
  * Run npm run build in the www directory to publish the results to
    dist.

 Backlog

  * [ ] Bug: Fix keyboard responsiveness.
  * [ ] Bug: Sanitize RAM and ROM inputs in wasm.
  * [ ] Bug: Index of instruction should be within ROM size.
  * [ ] Bug: Crash when Rect.hack is running with RAM[0] > 513.
  * [ ] Feature: Support for Hack assembly not just machine code.
  * [ ] Feature: Separate targets for wasm and pixels. Shouldn't have
    to comment code.
  * [*] Feature: Add keyboard support.
  * [*] Bug: Fix the render loop in wasm.
  * [*] Feature: Transfer words instead of pixels from wasm to js.
  * [*] Feature: Show sample ROMs and a file picker on the web page.
  * [*] Bug: Only first key press is being registered. (=> keymap had
    to be zeroed)
