Method Details

applyDiff

public static List<String> applyDiff(List<String> target,
 String diff)

Applies a diff in unified format to target.

If the LLM was handed code with unusual indentation, it can struggle to create a diff patch with that indentation preserved. This will attempt to fix the indentation of the original lines in the diff patch before passing it to UnifiedDiffUtils for parsing.

Parameters:

target - The target.

diff - The diff.

Returns:

The patched target.

Throws:

IllegalArgumentException - If the diff cannot be applied to target.
