stackconf 2024 - IGNITE: Swiss knife for Go debugging with VSCode by Ivan Presenti.pdf

Being able to debug your code in the IDE should be an easy process. If you ever struggled with debugging Go code in Visual Studio Code, this session is definitely for you. We’ll take a look at how to debug several kinds of projects by only tweaking settings in the dreaded “launch.json” file. You’ll discover how many options and customizations you can apply to this file to leverage your debugging experience. Finally, we briefly touch on the key features of the Delve debugger.

Why Debugging?
Get more familiar with the codebase you’re working with. Follow the execution
path to find out functions invoked.
Find out where bugs happen and fix them. Allow you to slow down the code
execution in specific parts to dig into them.
Inspect variables’ values or complex objects and how they change while code
execution.
