A demo of gdlv, a GUI debugger for Go

Gdlv is a GUI frontend for Delve that supports Windows, Linux and macOS. I will perform a live demonstration of its main features, including conditional breakpoints, expression evaluation, stepping through code and reversible debugging.

Abstract

Gdlv is a GUI frontend for Delve that supports Windows, Linux and macOS. I will perform a live demonstration of its main features, including conditional breakpoints, expression evaluation, stepping through code and reversible debugging. Debuggers are often perceived as tools that are only useful when trying to diagnose the causes of a program malfunction, but in reality they are also powerful tools to understand how an unfamiliar piece of code works. , as a preliminary step to extending or modifying it. In this demonstration I will use Gdlv, a stand-alone graphical front-end for Delve, to: 1.debug a toy example using hard-coded breakpoints, conditional breakpoints and finally reversible debugging (sometimes called “time-travel” debugging). 2.explore a real-world interactive program – ivy 3.explore a larger real-world program, the Go compiler, using reversible debugging and custom variable printing
