# diff-xyz-noisy

A noisy version of [diff-xyz](https://huggingface.co/datasets/JetBrains-Research/diff-xyz/) dataset. 
This dataset is obtained from the original one by replacing alpha symbols with another alpha symbol using a random character mapping.
Components: the original file contents (`old_code`), the modified contents (`new_code`), and the unified diff between
them (`diff_string`).

This format enables evaluation of LLM capabilities on three code editing tasks:

- **Apply**: Given old code and diff, generate new code
- **Anti-Apply**: Given new code and diff, generate old code
- **Diff-Generation**: Given old and new code, generate the unified diff
