Toolbox

Ruby debugging toolbox for GDB and LLDB, providing commands for inspecting Ruby objects, fibers, and VM internals across multiple debuggers.

• Multi-debugger support: Works with both GDB and LLDB through a unified abstraction layer.
• Object inspection: Pretty-print Ruby objects, hashes, arrays, and complex structures.
• Fiber debugging: Navigate and inspect Ruby fibers with full backtraces.
• Heap scanning: Search the Ruby heap for objects and diagnose memory issues.
• Stack inspection: Examine both Ruby VM stacks and native C stacks.
• Easy installation: Simple bake tasks for both GDB and LLDB.

Please see the project documentation for more details.

• Getting Started - This guide explains how to install and use Toolbox for debugging Ruby programs and core dumps with GDB or LLDB.

• Object Inspection - This guide explains how to use rb-print to inspect Ruby objects, hashes, arrays, and structs in GDB.
