Highlighting regular expressions syntax in code block

[infologie]

I am writing a little tutorial on regular expressions for students, with code blocks such as:

^Hello

Is there a way to highlight regular expressions syntax in code blocks? Something like:

```regex
^Hello
```

In this example, the ^ would be highlighted.

I did a very naïve check of pandoc --list-highlight-languages as well as KDE’s repository of syntax definitions for strings like "regex" or "pcre", but I am not familiar enough with programming languages to identify one that would do this, nor could I adapt something like Regex Colorizer to work with pandoc.

Has anyone else needed to do this?

Any help would be greatly appreciated.
