SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers efficiently debug Zig programs by providing guidance on using debuggers like GDB and LLDB, interpreting runtime panics, and leveraging built-in logging mechanisms.

Core Features & Use Cases

  • Debugger Integration: Step-by-step instructions for using GDB and LLDB with Zig executables.
  • Error Interpretation: Understand and resolve Zig panics and error return traces.
  • Logging and Tracing: Implement effective debugging with std.debug.print and std.log.
  • IDE Setup: Configure VS Code for seamless Zig debugging.
  • Use Case: When your Zig program crashes with an unhandled panic, this Skill guides you through setting breakpoints in GDB to pinpoint the exact line of code causing the issue and understand the panic message.

Quick Start

Use the zig-debugging skill to debug a Zig program using GDB.

Frequently Asked Questions about zig-debugging

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug a Zig program that crashes with an unhandled panic?▼

Debug a Zig crash by using GDB or LLDB to set breakpoints at the crash location, allowing you to pinpoint the exact line of code and interpret the runtime panic message to resolve the issue.

How do I set up VS Code for step-through Zig debugging?▼

Configure VS Code for Zig debugging by integrating GDB or LLDB extensions, resulting in a streamlined development environment for stepping through code execution and inspecting runtime variables.

What is the best way to trace execution flow in a Zig application?▼

Trace Zig execution flow by leveraging built-in logging mechanisms like std.debug.print and std.log to output runtime information, allowing you to monitor program behavior and verify logic paths.

How do I interpret Zig error return traces?▼

Interpret Zig error return traces by reading the propagated call stack output, which helps you identify where the error originated and track how it moved through your code to resolve the fault.

Can I use GDB and LLDB with Zig executables for step-by-step debugging?▼

Yes, GDB and LLDB both support Zig executables by providing step-by-step instructions for setting breakpoints, inspecting program state, and stepping through code during development.

Why does my Zig program panic and how can I find the cause?▼

Zig panics occur due to runtime errors like out-of-bounds access; find the cause by running the executable through GDB or LLDB to set breakpoints and examine the panic message directly.
