At present [this line of code](https://github.com/rustwasm/wasm-bindgen/blob/master/crates/cli-support/src/js/mod.rs#L747) creates the heap using JavaScript's new keyword.
```
//Line 747
self.global(&format!("const heap = new Array({});", INITIAL_HEAP_OFFSET));
self.global("heap.fill(undefined);");
```
Assuming that the `INITIAL_HEAP_OFFSET` is always 32 (because it is set as a constant in the Rust code), below is the equivalent of what this code will produce; an Array Object with 32 items which are all undefined.
```
const heap = new Array(32);
//(32) [empty × 32]
//Where
var zero_element = heap[0];
//undefined
var one_element = heap[1];
//undefined
```
I believe that this is the desired outcome for the program. All good.
### Suggestion to consider
I am always reminded **not** to use the `new` keyword. Mainly by reading or listening to JavaScript ["The Good Parts"](https://youtu.be/XFTOG895C7c?t=1654).
For example if the `INITIAL_HEAP_OFFSET` was ever anything but one number, the heap would be created in a different way. For example if two numbers are passed in, then an array of size 2 would be created; where both items in the array are individual numbers.
```
const heap = new Array(32, 32);
var zero_element = heap[0];
var one_element = heap[1];
//32
//32
```
I know that this is highly unlikely, due to the fact that the `INITIAL_HEAP_OFFSET` is set as a `const` in the Rust. But thought that I would put out the following suggestion for consideration anyway. This comes from a place of just wanting to contribute in a way that could make this already awesome program a little better. :)
### Suggested update
The heap array could be created using the following code
```
const heap = [];
heap.length = INITIAL_HEAP_OFFSET;
heap[0]
heap[1]
//undefined
//undefined
```
This would create a JavaScript Array of length `INITIAL_HEAP_OFFSET`, where are items are `undefined`
The new code generates (in raw JavaScript)
```
const heap = [];
heap.length = 32;
```
Which produces
```
(32) [empty × 32]
```
In the same way that the original code does.
* Add closing parenthesis to close out self.global
* Adding files which were altered by the BLESS=1 system variable. Essentially updating generated files that are used for testing.
* Adding code generated wat file, by way of running tests using BLESS=1
* Adding table.wat that was generated by running the tests with BLESS=1 set
* Update code that creates heap array line 747 mod.rs
* Updating files that are automatically generated when using BLESS=1
* add parameter to async function --> error
This change to the fetch example does not compile.
It would be great to include how to do this!
* fn parameter as String
The main gc pass of unused items in wasm-bindgen was accidentally
removing the function table because we weren't properly rooting it in
the auxiliary section which has a few ways that imports can reference
the function table via intrinsics and closures.
Closes#1967
This commit updates how TypeScript signature are generated from adapters
in wasm-bindgen. A richer set of `AdapterType` types are now stored
which record information about optional types and such. These direct
`AdapterType` values are then used to calculate the TypeScript
signature, rather than following the instructions in an adapter function
(which only works anyway for wasm-bindgen generated adapters).
This should be more robust since it reads the actual true signature of
the adapter to generate the TypeScript signature, rather than attempting
to ad-hoc-ly infer it from the various instructions, which was already
broken.
A number of refactorings were involved here, but the main pieces are:
* The `AdapterType` type is a bit more rich now to describe more
Rust-like types.
* The `TypescriptArg` structure is now gone and instead return values
are directly inferred from type signatures of adapters.
* The `typescript_{required,optional}` methods are no longer needed.
* The return of `JsBuilder::process` was enhanced to return more values,
rather than storing some return values on the structure itself.
Closes#1926
* Make console output "Hello from Rust!"
The HTML says the console would output Hello from Rust!, but instead it outputs Hello, World!
This is a proposed fix.
* Output "Hello from Rust!"
The HTML says the console would output "Hello from Rust!" but instead it outputs "Hello, World!".
This is a proposed fix.
The wasm-bindgen nightly test suite started failing recently and a
bisection shows that rust-lang/rust#67363 is the cause of this issue.
The problem happening here is that after that Rust PR duplicate imports
from the same name/module in different parts of a Rust program may now
show up as duplicate imports rather than being coalesced into one
import. This was tripping up `wasm-bindgen` which, when translating from
the wasm module to wasm-bindgen's IR, is unfortunately very
string-based.
The fix here was to detect these duplicate imports and map them all to
the same item, removing the duplicate imports.
Closes#1929
