Debugging Go With Delve: Beyond fmt.Println

Short summary

Delve is Go's native debugger offering conditional breakpoints, live variable modification, and goroutine-aware debugging—capabilities that far exceed fmt.Println. This tutorial walks through installation, setting breakpoints on function names or lines, and debugging concurrent code by switching between goroutines. Advanced features covered include attaching to running processes for production debugging, headless remote debugging mode, and hit-count conditions for finding race conditions in loops.

• •Delve replaces printf debugging with conditional breakpoints, variable inspection, and live state modification
• •Master goroutine debugging by listing all live goroutines, switching context, and inspecting stacks to find bottlenecks
• •Attach to running production processes with dlv attach or use headless mode for remote debugging from your laptop
