How to Enable Pretty Printing for STL Objects in Eclipse CDT?

Enable Pretty Printing for STL Objects in Eclipse CDT

Pretty printing is a feature that allows for improved visual representation of data when debugging C applications. To enable this functionality for STL objects in Eclipse CDT, follow these steps:

1. Python Module Installation

• Install the latest version of GDB that supports Python scripting.
• Download and checkout the Python pretty printers for STL objects into a directory of your choice.

2. Configuring GDB

• Create a .gdbinit file in your home directory.
• Add the following code to the file:

python
import sys 
sys.path.insert(0, '/PATH/TO/PRETTY_PRINTERS_DIRECTORY')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

3. Eclipse Configuration

• Download and install Eclipse CDT.
• Configure Eclipse to use the updated GDB and specify the path to the .gdbinit file.
• Enable the "Pretty Printing" option in the C/C Debug preferences.

4. Usage

• Start debugging your C application.
• STL containers will now be displayed in a more visually appealing manner in the "Variables" view.

5. Additional Commands

• To further enhance the output, consider using the following GDB commands:

set print pretty on
set print object on
set print static-members on
set print vtbl on
set print demangle on
set demangle-style gnu-v3
set print sevenbit-strings off
