You mean show it in the terminal instead of just showing the path as a link?

I am not sure if I like that option, especially because of long files. Maybe in a pager?

Pager works

I considered this feature, but unfortunately, it would mean adding a huge library like syntect for syntax highlighting. It also hides the advantages of having a language server for reading the docs of used items in the solution. "Go to definition" is also very useful if someone wants to take a deeper look at how an std function works.

That being said, I tried to highlight the solution in e7ba88f. Note that the shown path to the solution file is a terminal link. So you can click on it to open the solution file in your favorite editor :)
