Game Of Life example does not compile

[IngwiePhoenix]

Hey!

I just cloned this repo and wanted to test it out (while getting a little into TypeScript in general) and, following the instructions, came across this:

Ingwie@Ingwies-Macbook-Pro.local ~/W/g/a/e/game-of-life $ npm run asbuild

> @assemblyscript/game-of-life-example@1.0.0 asbuild /Users/Ingwie/Work/Git/assemblyscript/examples/game-of-life
> npm run asbuild:untouched && npm run asbuild:optimized


> @assemblyscript/game-of-life-example@1.0.0 asbuild:untouched /Users/Ingwie/Work/Git/assemblyscript/examples/game-of-life
> asc assembly/index.ts -b build/untouched.wasm -t build/untouched.wat --use Math=JSMath --importMemory --sourceMap --debug --validate --measure

Any idea why this happens?

just add tsconfig.json to your project directory with this content:

{
  "extends": "../node_modules/assemblyscript/std/assembly.json",
  "include": [
    "./**/*.ts"
  ]
}

AssemblyScript using own std definations and config

[MaxGraey]

It seems time to update examples...

[IngwiePhoenix]

I did that but I keep getting the error. There is a tsconfig.json present in the assembly folder as well.

How you install assemblyscript? May be you have old deprecated version from npm? Are you install as npm install github:AssemblyScript/assemblyscript?

[dcodeIO]

Strange, these are tsc diagnostics. It's expected that tsc cannot just compile the game of life example, but I wonder how npm run asbuild can even end up running tsc instead of asc.

Edit: I think Max is correct in that this is compiling with the prototype instead of master. Explains the tsc diagnostics.

[IngwiePhoenix]

Well what I did was to install the NPM package assemblyscript, ts-node and typescript to have some kind of "base". However, I installed this globally. I will try again with a local install.

[IngwiePhoenix]

Ouch! I did not see the deprecation warning... I am very sorry, I just noticed it.

[MaxGraey]

you shouldn't install assemblyscript from npm. npm contain deprecated version. Correct install process:

npm install --save-dev github:AssemblyScript/assemblyscript

This by the way described in README.md

[IngwiePhoenix]

I must have seriously overlooked that... Now, it works - and I am trying out AssemblyScript now! :) I am very curios as to where I can take and use this - it is definitively highly interesting.

Thank you for your support!

Why not publish new versions to NPM? That would seem to be more standard. Is it because it takes time and there's lots of changes happening often?
