## Description

Delta is a command-line pager that enhances the readability of terminal output by applying syntax highlighting and structured formatting to text streams. It functions as a specialized interface for version control systems, transforming standard output into color-coded, human-readable views.

The tool distinguishes itself through its ability to render side-by-side diff comparisons and visualize merge conflicts with clear, semantic highlighting. It dynamically calculates column widths and text alignment to fit complex file comparisons within the constraints of a terminal window, while allowing users to map token types to custom color palettes via external configuration files.

Beyond diff viewing, the project provides utilities for formatting git blame output, highlighting search results, and displaying line numbers. It processes input line-by-line to maintain a low memory footprint, integrating external language definitions to ensure accurate syntax coloring across various codebases.
