compile result is always a wrong file ?

[QiangYuzhou]

My step:

1. git clone, nom install, npn link, nom clean.

2. try to create a new file, which is :

export function add(a: u64, b: u64): u64{
  return a + b;
}

3. run the command: ./bin/asc ./example/helloworld/helloworld.ts -t outputFile.wat -b outputFile.wasm

4. The result output.wat is a confusing file with size 55KB:

(module
 (type FUNCSIGiii (func (param i32 i32) (result i32)))
 (type FUNCSIGv (func))
 (type FUNCSIGiiii (func (param i32 i32 i32) (result i32)))
 (type FUNCSIGviiii (func (param i32 i32 i32 i32)))
 (type FUNCSIGvii (func (param i32 i32)))
 (type FUNCSIGii (func (param i32) (result i32)))
 (type FUNCSIGviii (func (param i32 i32 i32)))
 (type FUNCSIGvi (func (param i32)))
 (type FUNCSIGjjj (func (param i64 i64) (result i64)))

There is nothing related to my entry file. And Many things are included such as $~lib/rt/pure/__visit ​$~lib/memory/mempry.copy...

So I try another way:

1. npx init.

2. npm run asbuild.
   The entry file is below:

// The entry file of your WebAssembly module.

export function add(a: i32, b: i32): i32 {
  return a + b;
}

And the result is that, the same file created.

I don't know why, and I really appreciate if you could help me!

Most of the code you are seeing there comes from the inclusion of the AssemblyScript runtime for memory management and GC. Your add function should be somewhere in there as well. If you do not need the runtime, try specifying --runtime none on the command line, which will yield a much smaller module.

Thanks! It really works!
