Seer is a graphical frontend to GDB, the GNU Debugger. It provides developers with a convenient way to investigate program execution without having to remember a large collection of debugger commands.
The interface brings together source code, variables, registers, stack frames and debugging controls in a collection of panels. Developers can navigate through a program, set breakpoints and examine changes in program state as execution progresses.
Seer also includes facilities for visualising memory and arrays, making it useful when investigating data structures or unexpected values. It communicates with GDB through its machine interface and uses the Qt toolkit.
This is free and open source software.
Key Features
- Display source files with syntax highlighting, searchable code and debugging controls.
- Set and manage breakpoints, conditional watchpoints, catchpoints and printpoints.
- Inspect local variables, CPU registers, stack frames and thread information.
- Track selected variables and monitor their values as program execution progresses.
- Examine raw memory and disassembly through a dedicated memory visualiser.
- Visualise arrays with graphical plots, including spline, scatter and X-Y representations.
- Display assembly instructions alongside source code and set instruction-level breakpoints.
- Support GDB’s reverse debugging facilities, including execution recording and playback direction.
- Enter GDB commands directly when functionality is not exposed through the graphical interface.
- Detach code and debugging panels to arrange the workspace across multiple windows.
