Highlight.js version: 11.6.0
Node version: v18.12.0
npm version: 8.19.12
When I provide a plugin with the following code to highlightjs (full code is at github):
/*
Language: BQN
Requires:
Author: Raghu Ranganathan <rraghu.11502@gmail.com>
Contributors:
Description: BQN array language definitions
Website: https://mlochbaum.github.io/BQN
*/
export default function(hljs) {
return {
name: "BQN",
unicodeRegex: true,
keywords: '•BQN •ReBQN •primitives', // only primitive functions included.
contains: [
{
scope: 'string',
begin: '"', end: '"'
}
}
I get the following error during build:
$ node tools/build.js -t node
Starting build.
Finished build.
Writing styles.

What is causing this error?

Answer from allejo (highlightjs contributor):
In your language file, remove your empty Requires: line in the comment. After removing that, it should let you compile again. The comment is significant to the build process.
This will likely be handled silently or throw a warning in a future version of highlight.js.
