To replace codes in other languages
First, let's open this script's edit screen. There are two methods.
Method 1: Adding a dependency library
Copy the URL of the script for your language from the list at https://cdnjs.com/libraries/highlight.js.
Next, find this line in the top of the script.
// @require https://cdnjs.cloudflare.com/ajax/libs/highlight.js/10.1.2/highlight.min.js
Then add the line below after the line above. Replace {copied URL here} with the URL you just copied.
// @require {copied URL here}
Method 2 Using eval().
By this method, you can highlight any languages that highlight.js supports. However, as is well known, it is dangerous to use eval(). Be careful of using this method.
Find these lines near line 84.
if (!hljs.getLanguage(name)) {
// const response = await fetch(`https://cdnjs.cloudflare.com/ajax/libs/highlight.js/10.1.2/languages/${name}.min.js`);
// eval(await response.text());
return;
}
Then rewrite them as follows.
if (!hljs.getLanguage(name)) {
const response = await fetch(`https://cdnjs.cloudflare.com/ajax/libs/highlight.js/10.1.2/languages/${name}.min.js`);
eval(await response.text());
// return;
}
To use another themes
By default, default.css of highlight.js is used. To change themes, choose and copy the URL of css from https://cdnjs.com/libraries/highlight.js .
Next, find this line in the top of the script.
// @resource css https://cdnjs.cloudflare.com/ajax/libs/highlight.js/10.1.2/styles/default.min.css
Then replace the line above with the line below. Replace {copied URL here} with the URL you just copied.
// @resource css {copied URL here}
