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 "`"
