Description

This PR implements the missing functionality to apply a patch in the csharpdiff repository. The Apply method in the PatchApply class has been implemented to parse a unified diff string and apply the changes to a given source string.

Summary of Changes

  • Implemented the Apply method in the PatchApply class to parse a unified diff string and apply the changes to a source string.
  • Parsed the unified diff string into a list of changes, each specifying an operation, position, and text.
  • Applied the changes to the source string in the order they appear in the diff.
  • Returned the resulting string after all changes have been applied.

Fixes #3.

I'm getting the same errors 3 times in a row, so I will stop working on fixing this PR.

Hi @ThomasHambach,

I decided to make the following changes:

File Path Proposed Changes
CSharpDiff/Patches/PatchApply.cs Modify CSharpDiff/Patches/PatchApply.cs with contents:
• Add a closing curly brace (}) at the end of the PatchApply class in the PatchApply.cs file.
CSharpDiff.Tests/PatchTests.cs Modify CSharpDiff.Tests/PatchTests.cs with contents:
• Investigate the IndexOutOfRangeException in the unit tests and fix the issue causing it.
