@suin/refractor-flatten

A utility to transform Refractor ASTs to flat arrays.

Installation

yarn add @suin/refractor-flatten
# or
npm install @suin/refractor-flatten

Usage

Basic Usage

import refractor from "refractor";
import flatten from "@suin/refractor-flatten";

const tree = refractor.highlight("`${value}`", "js");
const flat = flatten(tree);

The structure of tree is:

root[1]
└─0 element<span>[3]
    │ properties: {"className":["token","template-string"]}
    ├─0 element<span>[1]
    │   │ properties: {"className":["token","template-punctuation","string"]}
    │   └─0 text "`"
    ├─1 element<span>[3]
    │   │ properties: {"className":["token","interpolation"]}
    │   ├─0 element<span>[1]
    │   │   │ properties: {"className":["token","interpolation-punctuation","punctuation"]}
    │   │   └─0 text "${"
    │   ├─1 text "value"
    │   └─2 element<span>[1]
    │       │ properties: {"className":["token","interpolation-punctuation","punctuation"]}
    │       └─0 text "}"
    └─2 element<span>[1]
        │ properties: {"className":["token","template-punctuation","string"]}
        └─0 text "`"

The structure of the flat above becomes:

root[5]
├─0 element<span>[1]
│   │ properties: {"className":["token","template-string","template-punctuation","string"]}
│   └─0 text "`"
├─1 element<span>[1]
│   │ properties: {"className":["token","template-string","interpolation","interpolation-punctuation","punctuation"]}
│   └─0 text "${"
├─2 element<span>[1]
│   │ properties: {"className":["token","template-string","interpolation"]}
│   └─0 text "value"
├─3 element<span>[1]
│   │ properties: {"className":["token","template-string","interpolation","interpolation-punctuation","punctuation"]}
│   └─0 text "}"
└─4 element<span>[1]
    │ properties: {"className":["token","template-string","template-punctuation","string"]}
    └─0 text "`"
