An Emacs minor mode that highlights nested delimiters with different colors according to their depth.
Rainbow-delimiters is an Emacs minor mode that applies color highlighting to nested delimiters like parentheses, brackets, and braces based on their depth level. It solves the problem of visual confusion in deeply nested code by making delimiter matching and code structure immediately apparent. The mode is designed to be fast and unobtrusive, enhancing readability without impacting editing performance.
Emacs users who work with programming languages that involve heavy nesting, such as Lisp dialects (Clojure, Emacs Lisp), or any language where delimiter matching is crucial for code comprehension.
Developers choose rainbow-delimiters for its performance-optimized design that avoids slowdowns, its subtle and customizable color themes, and its ability to work seamlessly across all programming languages. It stands out by focusing on speed and integration with popular Emacs color schemes.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Optimized to avoid slowdowns in scrolling or editing, as emphasized in the README for delimiter-rich languages like Clojure or Emacs Lisp.
Uses intentionally unobtrusive colors that integrate well with popular themes like Zenburn and Solarized, reducing visual distraction.
Works with any programming language that uses delimiters, providing universal applicability without language-specific setup.
Allows defining custom colors for each depth level and includes faces for unmatched or mismatched delimiters to aid debugging, as detailed in the customization section.
The README explicitly states that a global mode was removed due to compatibility issues with some major modes, forcing users to rely on per-mode hooks.
Requires manual addition to major mode hooks for automatic enabling, which can be cumbersome compared to plug-and-play global minor modes.
Only provides customizable faces for depths 1-9, which may be insufficient for extremely deeply nested code in languages like Lisp.
