## What is this?

This package is a [unified][] plugin that defines how to take [pixiv novel][pixiv-novel] format
as input and turn it into a syntax tree.

## Install

This package is [ESM only](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c).
in Node.js (18.0+), Install with [npm][]:

```shell
npm install @rshirohara/repixe-parse
```

## Use

Say we have the following module `example.js`:

```js
import { unified } from "unified";
import { repixeParse } from "@rshirohara/repixe-parse";

main();

async function main() {
  const source = [
    "これが一段落目\n\n",
    "ここから二段落目",
    "[[rb:二行目>にぎょうめ]]",
    "[[jumpuri:リンク>https://example.com]]も使える。"
  ].join("\n");
  const ast = await unified().use(repixeParse).parse(source);

  console.log(ast);
}
```

Running that with `node example.js` yields:

```js
{
  type: "root",
  children: [
    {
      type: "paragraph",
      children: [
        {type: "text", value: "これが一段落目"}
      ]
    },
    {
      type: "paragraph",
      children: [
        {type: "text", value: "ここから二段落目"},
        {type: "break"},
        {type: "ruby", value: "二行目", ruby: "にぎょうめ"},
        {type: "break"},
        {type: "link", url: "https://example.com", children: [
          {type: "text", value: "リンク"}
        ]},
        {type: "text": value: "も使える"}
      ]
    }
  ]
}
```
