C-Tycat: debugging graph for C

C-Tycat is a module that allows you to visually debug your program. From a variable it creates a graph showing the current data tree.

This project is named C-Tycat because it use the tycat command from terminology to display generated images directly in your terminal. Please note that it is still possible to save this image instead of displaying it in the terminal.

There are two ways to use C-Tycat: directly in C through a library or as a GDB extension.

c-lib: C-Tycat C library

The C library of C-Tycat. This library can be used either statically (with libctys.a) or dynamically (with libctyd.so).

This library requires libdw-dev and grahviz to be installed in your Linux distribution.

gdb-c: GDB C extension

A GDB extension for tycat'ing variables in the GDB context. This extension uses the C library of C-Tycat either static or dynamic.

This following commands are added to GDB:

• ty <varname>: tycat a variable
• ty-config <key> [<value>]: get or set a configuration option

gdb-py: GDB Python extension

Another GDB extension that this time does not use the C library. This extension is entirely written in Python and uses the GDB script API.

This extension is a bit slower than gdb-c extension but uses less memory (because the debug symbols are only loaded once).

This extension is under development, please gdb-c extension for the moment.
