import hljs from "highlight.js/lib/core";
import { highlightPlugin } from "prosemirror-highlightjs";
let state = new EditorView(..., {
state: EditorState.create({
doc: ...,
plugins: [highlightPlugin(hljs)],
})
});
Or import just the decoration parser and write your own plugin:
import { getHighlightDecorations } from "prosemirror-highlightjs";
let plugin = new Plugin({
state: {
init(config, instance) {
let content = getHighlightDecorations(
instance.doc,
hljs,
blockTypes,
languageExtractor
);
return DecorationSet.create(instance.doc, content);
},
apply(tr, set) {
if (!tr.docChanged) {
return set.map(tr.mapping, tr.doc);
}
let content = getHighlightDecorations(
tr.doc,
hljs,
blockTypes,
languageExtractor
);
return DecorationSet.create(tr.doc, content);
},
},
props: {
decorations(state) {
return this.getState(state);
},
},
});
Due to how ProseMirror renders decorations, some existing highlight.js themes might not work as expected.
ProseMirror collapses all nested/overlapping decoration structures, causing a structure such as
.hljs-function > (.hljs-keyword + .hljs-title)
to instead render as .hljs-function.hljs-keyword + .hljs-function.hljs.title
.
