GhostScope v0.1.3
Overview
GhostScope v0.1.3 focuses on making source-aware tracing easier to use, especially from the command line and in AI-assisted workflows.
This release significantly improves the CLI experience and introduces installable GhostScope skills, making it much easier to use AI to write GhostScope tracing scripts from source trees, DWARF-enabled binaries, and runtime context. Alongside that, we continued expanding Docker support, strengthened inline and DWARF handling, and fixed a number of important correctness and usability issues.
Highlights
- Improved CLI script-mode usability with better output formatting, color controls, and clearer status reporting
- Added embedded
--script-helpso scripting help is available directly from theghostscopebinary - Introduced installable GhostScope skills and curl-based installation
- Made AI-assisted tracing workflows much more practical, helping users generate GhostScope scripts more easily
- Expanded Docker and container support. See the Container Guide for PID namespace behavior, supported topologies, and current limitations.
- Strengthened inline handling and DWARF resolution in optimized and origin-backed cases
Bug Fixes
This release also includes a broad set of fixes across the tracing pipeline, including:
- Better error reporting for
printbuiltin failures viaExprError - Cleaner separation between script output and status prompts
- Fixes for scalar DWARF expression capture lengths
- Correct trace event PID/TID ordering
.bssrebasing fixes and stronger global/static variable handling- Multiple DWARF and inline resolution fixes for optimized and edge-case builds
Thanks
Special thanks to @philipc for helping upgrade gimli and for identifying a critical bug that helped drive several of the DWARF correctness improvements in this release.
What's Next
Next, I will continue focusing on:
- Improving DWARF analysis stability
- Reducing startup-time overhead, especially during the initial DWARF analysis phase
If that work goes well, I plan to start exploring a new backtrace command built on eBPF-powered, DWARF-aware stack unwinding.
GhostScope v0.1.1-beta
What's changed
- Release binaries no longer depend on the libffi dynamic library, making deployments lighter.
- Enhanced scripting language with more user-friendly error messages.
- Improved -t mode with support for probing global variables.
- Better inline-function support: trace/info output now includes address indices and inline markers.
- UI/tooling upgrades: source panel can be hidden via configuration, command parsing is more robust, and long trace messages auto-collapse.
- Numerous bug fixes😁.

GhostScope v0.1.0-beta
Overview
GhostScope is a runtime tracing tool that brings the simplicity of printf debugging to production systems. It leverages DWARF debug information and eBPF/uprobe technology to safely extract and display variable values, function arguments, complex data structures, and stack backtraces from running programs — all without stopping or modifying them.
"The most effective debugging tool is still careful thought, coupled with judiciously placed print statements." — Brian Kernighan

⚠️ Beta Release Notice
This is a beta release for early testing and feedback.
Known Limitations
- Language: Currently supports C language only. C++ and Rust basic features support coming soon.
- Platform: x86_64 (amd64) only.
- Optimized Builds: Detection is limited for heavily optimized binaries (e.g., -O2/-O3, LTO). Support is in progress and will improve in upcoming releases
