# Usage

## CLI

This repository contains two executable files, namely clang-format and git-clang-format.

For more information, please refer to https://clang.llvm.org/docs/ClangFormat.html

## API

```JavaScript

import init, { format } from "@wasm-fmt/clang-format";

await init();

const source = `

#include 

using namespace std;

auto main() -> int{

std::cout << "Hello World!" << std::endl;

return 0;}

`;

// JSON representation of Clang-Format Style Options

const config = JSON.stringify({

  BasedOnStyle: "Chromium",

  IndentWidth: 4,

  ColumnLimit: 80,

});

// or YAML representation of Clang-Format Style Options which is used in `.clang-format` file

const config2 = `---

BasedOnStyle: Chromium

IndentWidth: 4

ColumnLimit: 80

...

`;

// or the preset name

const config3 = "Chromium";

const formatted = format(

    source,

    "main.cc",

    config,

);

console.log(formatted);

```

The third argument of `format` is a Clang-Format Style Options, which can be one of the following:

1. A preset: LLVM, GNU, Google, Chromium, Microsoft, Mozilla, WebKit.

2. A YAML/JSON string representing the style options.

3. the string content of a `.clang-format` file.

See [Clang-Format Style Options](https://clang.llvm.org/docs/ClangFormatStyleOptions.html) for more information.
