• Show some of the fields in the moduledata structure. According to the source code, the moduledata "records information about the layout of the executable image."

$ redress moduledata ./redress

DEV 2022-05-20

DEV 2022-05-19

Development release with some additional features since the last tag. Changes includes:

• New command to print type definition based on an offset.
• Go 1.18 support.
• Print extracted module data.

Version 1.0.0

It's been over two years since the first public release of redress and a lot has changed since then. Redress has finally reached version 1.0. This release includes many surface and under the hood changes. One of the obvious changes is the user interface which has been rewritten to make it easier to use.

The Go Reverse Engineering Tool Kit (GoRE) has had a lot of improvements during the last few months and redress is taking advantage of these improvements. Some of these improvements are:

• Improved compiler version detection.
• A rewritten type parser.
• Improved package type classification (part of the main module vs a 3rd party module).
• Support for position-independent executables (PIE).
• Improved source code line number estimation and performance improvements.
• Extraction of GoRoot.
