How to Debug Go Programs with Delve (dlv)

You debug Go programs by attaching the Delve debugger to your binary or running it directly with dlv.

dlv debug ./main.go

Inside the Delve REPL, use break main to set a breakpoint, continue to run until that point, and next or step to execute line by line. Use print variableName to inspect values and list to view source code context.

Delve is a tool that lets you pause your Go program while it runs to check what is happening inside. It works like a video game pause button, allowing you to look at variable values and step through code one line at a time to find errors.
