GitHub Code Line Wrap is a Chrome add-on designed to improve the readability of code during reviews on GitHub. This free extension addresses a common issue where the GitHub web UI wraps lines in a word-processor style, which can lead to confusion, especially with languages like Python that rely heavily on indentation. By applying additional CSS to GitHub pages, this tool ensures that lines wrap at the first character that exceeds the view width, maintaining the original formatting of the code.

The extension offers a straightforward solution to enhance the code review process by keeping the content within the pane and presenting it in a format similar to traditional code editors like Vim. Unlike other methods that may fully unwrap lines, potentially leading to overlapping text, GitHub Code Line Wrap retains clarity and structure, making it easier for developers to review and understand the code without losing the essential indentation context.
