Cannot find global type 'CallableFunction'

[ckaznocha]

Bug description

Opening an assemblyscript project with vscode results in the error "Cannot find global type 'CallableFunction'" from the tsconfig.json. It looks like this is caused by the noLib being true and no global definition for CallableFunction in the assemblyscript d.ts files. This only started for me after I updated to the latest version of vscode which I'm under the impression comes with a bundled version of typescript.

I found some folks on so are having the same problem with no resolution but I wasn't able to find an issue here so creating one.

Steps to reproduce

Open an assemblyscript project with vscode v1.75.0 then edit any ts file.

AssemblyScript version

v0.26.7

Seems we'll need to declare a mock CallableFunction in std/index.d.ts, where the noLib environment is declared, so TS tooling can pick it up. Might be as simple as copy-pasting the interface TS uses.

I ran into this as well. Turns out newer versions of TypeScript have stricter typing for bind, call, and apply. See TypeScript 3.2 released with configuration inheritance and more under the strictBindCallApply heading for a bit more detail.

For now, you can disable these newer types by changing your project's tsconfig.json and setting strictBindCallApply to false like this:

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

Thanks for posting this workaround @neodon! I tried it in a project and can confirm it suppresses the new errors from the tsconfig.json.
