Usage

CLI

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 for more information.
