delta is a cross-platform syntax-highlighting pager designed to enhance the readability of git, diff, and grep output by colorizing additions, deletions, and context lines while keeping the familiar interface of standard pagers such as less. Originally released by Dan Davison and now maintained as an open-source project under the MIT license, delta 0.18.2 represents the seventh stable iteration, building on earlier versions to refine performance and expand language support. The utility integrates transparently with Git, requiring only a one-time pager configuration to replace the default diff viewer, after which every git diff, git show, git log -p, or git stash show command is automatically rendered with side-by-side or line-by-line layouts, Unicode box drawing, and optional line-numbering. Beyond Git, delta can be piped conventional unified diff or grep output, making it equally valuable for reviewing patch files, continuous-integration logs, or ripgrep results in a terminal that supports 24-bit color. Configuration is managed through a single .gitconfig or delta-specific file, allowing teams to standardize color schemes, whitespace handling, and merge conflict presentation. Because delta relies on the syntect library—the same engine that powers Visual Studio Code—its highlighting covers more than one hundred programming and markup languages, ensuring that code changes are intelligible regardless of project type. The tool is distributed as a single statically linked binary for Windows, macOS, and Linux, eliminating runtime dependencies and simplifying enterprise deployment. delta is available for free on wget.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
