Thanks for sharing your gist. I was able to adapt it for Colab for Kotlin as the Kotlin kernel by Jetbrains doesn't work and syntax highlighting doesn't work either for Colab out of the box. So I now have syntax highlighting for Kotlin!! Otherwise to suppress weird syntax error highlighting had to use workaround use %%writefile or %%script magics
I figure it's good to have a record of code that is runnable. I find it interesting that Google's Kotlin tutorials uses Kotlin Playground which doesn't show the compiling under the hood which previous commenter wasn't happy re this gist for c++, c, java...
If you are doing a lot of code this plugin is useful to save time.

If we want to run c++ or c, or java program on google colab , we can quickly run on it. Would you please follow this article that gives the best idea to run the program on google colab.
