It's time. Rockstar 2: "The Difficult Second Version"

The Build Process

Building codewithrockstar.com works like this:

build-and-test-rockstar-engine

• runs on Linux
• Builds the parser and interpreter
• Runs the test suite
• Uploads artifacts for:
  • linux native binary
  • WASM interpreter for the website

IF THAT WORKS:

build-windows-binary

• builds the Rockstar windows binary

build-macos-binary

• builds the macOS binary

build-and-deploy-website * Downloads the linux binary Rockstar WASM artifact from step 1 * Downloads the windows and macOS binaries from steps 2 and 3 * Builds the Jekyll site

Debug/Dev Mode Setup

In dev mode, I use symbolic directory links between the various parts of the project. Rebuilding the .NET solution will rebuild the WASM interpreter, which Jekyll can see as /wasm/**, and trigger a site rebuild, and all the Rockstar code examples are part of both the Rockstar.Test .NET test suite project and the codewithrockstar.com site:

> cd codewithrockstar.com
> mklink /d wasm ..\Starship\Rockstar.Wasm\bin\Debug\net8.0-browser
> mklink /d examples ..\Starship\Rockstar.Test\programs\examples

codewithrockstar.com
  /wasm --> [ /Starship/Rockstar.Wasm/bin/Debug/net8.0-browser ]
  /examples --> [ /Starship/Rockstar.Test/programs/examples ]

Function currying

output
  function call: product
    function call: sum
      number: 2
      number: 4
      function call: sum
        number: 5
        number: 6

So: product(sum(2,4,sum(5,6)) needs to be translated to product(sum(2,4),sum(5,6)) based on the arity of the functions

So sum(2,4,sum(5,6)) needs to evaluate sum(2,4) and leave the expression sum(5,6) in the bucket

Then product(sum(2,4)
