About Delta
Delta is a syntax-highlighting pager for git, diff, grep, rg --json, and blame output. The package is called "git-delta" in most package managers with executable delta, and it is used by setting it as the pager in ~/.gitconfig.
It provides language syntax highlighting, word-level diff highlighting, side-by-side view with line wrapping, line numbers, and movement between diff sections. It also handles merge conflicts, blame display, traditional unified diff output, and Git's --color-moved feature.
