binaryen.js
===========
**binaryen.js** is a port of [Binaryen](https://github.com/WebAssembly/binaryen) to the Web, allowing you to generate [WebAssembly](https://webassembly.org) using a JavaScript API.
<a href="https://github.com/AssemblyScript/binaryen.js/actions?query=workflow%3ABuild"><img src="https://img.shields.io/github/workflow/status/AssemblyScript/binaryen.js/Build/main?label=build&logo=github" alt="Build status" /></a>
<a href="https://www.npmjs.com/package/binaryen"><img src="https://img.shields.io/npm/v/binaryen.svg?label=latest&color=007acc&logo=npm" alt="npm version" /></a>
<a href="https://www.npmjs.com/package/binaryen"><img src="https://img.shields.io/npm/v/binaryen/nightly.svg?label=nightly&color=007acc&logo=npm" alt="npm nightly version" /></a>
Usage
-----
```
$> npm install binaryen
```
```js
var binaryen = require("binaryen");
// Create a module with a single function
var myModule = new binaryen.Module();
myModule.addFunction("add", binaryen.createType([ binaryen.i32, binaryen.i32 ]), binaryen.i32, [ binaryen.i32 ],
myModule.block(null, [
myModule.local.set(2,
myModule.i32.add(
myModule.local.get(0, binaryen.i32),
myModule.local.get(1, binaryen.i32)
)
),
myModule.return(
myModule.local.get(2, binaryen.i32)
)
])
);
myModule.addFunctionExport("add", "add");
// Optimize the module using default passes and levels
myModule.optimize();
// Validate the module
if (!myModule.validate())
throw new Error("validation error");
// Generate text format and binary
var textData = myModule.emitText();
var wasmData = myModule.emitBinary();
// Example usage with the WebAssembly API
var compiled = new WebAssembly.Module(wasmData);
var instance = new WebAssembly.Instance(compiled, {});
console.log(instance.exports.add(41, 1));
```
The buildbot also publishes nightly versions once a day if there have been changes. The latest nightly can be installed through
```
$> npm install binaryen@nightly
```
or you can use one of the [previous versions](https://github.com/AssemblyScript/binaryen.js/tags) instead if necessary.
### Usage with a CDN
* From GitHub via [jsDelivr](https://www.jsdelivr.com):<br />
`https://cdn.jsdelivr.net/gh/AssemblyScript/binaryen.js@VERSION/index.js`
* From npm via [jsDelivr](https://www.jsdelivr.com):<br />
`https://cdn.jsdelivr.net/npm/binaryen@VERSION/index.js`
* From npm via [unpkg](https://unpkg.com):<br />
`https://unpkg.com/binaryen@VERSION/index.js`
Replace `VERSION` with a [specific version](https://github.com/AssemblyScript/binaryen.js/releases) or omit it (not recommended in production) to use main/latest.
API
---
**Please note** that the Binaryen API is evolving fast and that definitions and documentation provided by the package tend to get out of sync despite our best efforts. It's a bot after all. If you rely on binaryen.js and spot an issue, please consider sending a PR our way by updating [index.d.ts](./index.d.ts) and [README.md](./README.md) to reflect the [current API](https://github.com/WebAssembly/binaryen/blob/main/src/js/binaryen.js-post.js).

#### [Function calls](http://webassembly.org/docs/semantics/#calls)
* Module#**call**(name: `string`, operands: `ExpressionRef[]`, returnType: `Type`): `ExpressionRef`
Creates a call to a function. Note that we must specify the return type here as we may not have created the function being called yet.
* Module#**return_call**(name: `string`, operands: `ExpressionRef[]`, returnType: `Type`): `ExpressionRef`<br />
Like **call**, but creates a tail-call. 🦄
* Module#**call_indirect**(target: `ExpressionRef`, operands: `ExpressionRef[]`, params: `Type`, results: `Type`): `ExpressionRef`<br />
Similar to **call**, but calls indirectly, i.e., via a function pointer, so an expression replaces the name as the called value.
* Module#**return_call_indirect**(target: `ExpressionRef`, operands: `ExpressionRef[]`, params: `Type`, results: `Type`): `ExpressionRef`<br />
Like **call_indirect**, but creates a tail-call. 🦄

Creates a deep copy of an expression.
### Relooper
* new **Relooper**()<br />
Constructs a relooper instance. This lets you provide an arbitrary CFG, and the relooper will structure it for WebAssembly.
* Relooper#**addBlock**(code: `ExpressionRef`): `RelooperBlockRef`<br />
Adds a new block to the CFG, containing the provided code as its body.
* Relooper#**addBranch**(from: `RelooperBlockRef`, to: `RelooperBlockRef`, condition: `ExpressionRef`, code: `ExpressionRef`): `void`<br />
Adds a branch from a block to another block, with a condition (or nothing, if this is the default branch to take from the origin - each block must have one such branch), and optional code to execute on the branch (useful for phis).
* Relooper#**addBlockWithSwitch**(code: `ExpressionRef`, condition: `ExpressionRef`): `RelooperBlockRef`<br />
Adds a new block, which ends with a switch/br_table, with provided code and condition (that determines where we go in the switch).
* Relooper#**addBranchForSwitch**(from: `RelooperBlockRef`, to: `RelooperBlockRef`, indexes: `number[]`, code: `ExpressionRef`): `void`<br />
Adds a branch from a block ending in a switch, to another block, using an array of indexes that determine where to go, and optional code to execute on the branch.
* Relooper#**renderAndDispose**(entry: `RelooperBlockRef`, labelHelper: `number`, module: `Module`): `ExpressionRef`<br />
Renders and cleans up the Relooper instance. Call this after you have created all the blocks and branches, giving it the entry block (where control flow begins), a label helper variable (an index of a local we can use, necessary for irreducible control flow), and the module. This returns an expression - normal WebAssembly code - that you can use normally anywhere.
### Source maps
* Module#**addDebugInfoFileName**(filename: `string`): `number`<br />
Adds a debug info file name to the module and returns its index.
* Module#**getDebugInfoFileName**(index: `number`): `string | null` <br />
Gets the name of the debug info file at the specified index.
* Module#**setDebugLocation**(func: `FunctionRef`, expr: `ExpressionRef`, fileIndex: `number`, lineNumber: `number`, columnNumber: `number`): `void`<br />
Sets the debug location of the specified `ExpressionRef` within the specified `FunctionRef`.
### Debugging
* Module#**interpret**(): `void`<br />
Runs the module in the interpreter, calling the start function.
