Cross-platform tool that allows browsing and extracting C and C++ type declarations from PDB files.

resym

resym is a utility that allows browsing and extracting types from PDB files.

Inspired by PDBRipper and pdbex.

Key Features

• Cross-platform
• GUI and CLI versions available
• C and C++ types reconstruction
• C and C++ types diff generation (between two PDBs)
• Decent performance, even on huge PDB files

Know limitations

The GUI version might struggle to display huge outputs (>20 MB). Disabling syntax highlighting (or dependency reconstruction altogether) will help, but generally the CLI version is more suited when dumping types with a huge amount of dependencies.

Why Another PDB Dumper?

I often need to extract and analyze C++ types from 1GB+ PDB files comfortably, in an interactive manner, but I haven't been able to find a tool that ticks all the boxes for me so far, so this my shot at making that tool.
So if you're in the same boat, this some tool might be of some use to you.

How to Build

On Ubuntu, you might need to install: libxcb-shape0-dev and libxcb-xfixes0-dev.

# Optional: install rust
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh 

$ git clone https://github.com/ergrelet/resym.git
$ cd resym; cargo build --release
$ ./target/release/resym

How to Use

If you want to use the GUI version, simply run the resym executable.
A CLI version (named resymc) is also available:

resymc 0.2.0
resymc is a utility that allows browsing and extracting types from PDB files.

USAGE:
    resymc.exe <SUBCOMMAND>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    diff    Compute diff for a type between two given PDB files
    dump    Dump type from a given PDB file
    help    Prints this message or the help of the given subcommand(s)
    list    List types from a given PDB file
