问题
I developing a code based chat component. Every chat is some code snippet. For user input, I am using monaco-editor. It works fine.
But as soon as user hits send button, I get raw input from Monaco editor. I need to append this user input to chat list and again highlight this input.
Is there a way I can use Monaco editor to do this? Or do I have to use highlight.js along with Monaco?
回答1:
I had the same problem so I created an issue #1171:
- https://github.com/Microsoft/monaco-editor/issues/1171
and two solutions were provided:
a) Format an existing HTML element:
monaco.editor.colorizeElement(document.getElementById("yourElement"));
b) Format a text which is not part of any element. This is a more generic approach which returns a Promise:
const code = "source code";
monaco.editor.colorize(code, "javascript")
.then(html => document.getElementById("yourElement").innerHTML = html);
Documentation:
- https://microsoft.github.io/monaco-editor/api/modules/monaco.editor.html#colorize

In case someone is still searching, there's currently a declarative syntax highlighter for Monaco Editor, called Monarch
