The Patch Debugger is a tool designed to help you understand why a patch might not be applying successfully. It provides insights into the matching process between the patch and the target text, helping you identify issues and improve the patch.
Match Scoring: The debugger evaluates the match score for each hunk in the patch against the target text. The match score indicates how well the hunk aligns with the text.
Positional Constraints: The debugger allows you to set a specific position in the text where the matching process begins. This helps you focus on particular sections of the text and understand the impact of different starting positions.
Penalties and Rewards: The scoring system includes penalties for missing lines and non-consecutive matches. It also rewards positive matches based on the specified position.

Install Go (if not already installed) Make sure you have Go installed on your system. You can download it from https://golang.org/dl/.
-
Clone the Repository Clone the Patch Debugger repository to your local machine
-
Make and Run the Debugger Use the following commands to run the debugger:
now it is quite easy to build:
go build main.go
run is also easy
./main -patch file.patch
- View Results Run the debugger against a patch results in a colored log.
