Howto?: fixing plugin to give background highlighting to a selected text evaluated in REPL

[aqjune]

Hi,

I would like to highlight the background color of a selected text whenever I evaluate that in REPL.

I would like to do this by updating https://github.com/ocamllabs/vscode-ocaml-platform/blob/master/src/repl.ml#L172-L190 , but I have no idea what to write. Can anyone give hints for me?

#1382 has that!
