Highlight

Overview

Highlight is an efficient syntax highlighting gem designed for Ruby and Rails that leverages the powerful Pygments highlighter written in Python. With its versatility, Highlight supports a wide range of programming languages, making it an ideal choice for developers seeking clarity and robustness in their code presentations. If Pygments is available on your system, it will utilize that; otherwise, you can seamlessly fall back on the web API provided by Simplabs.

The integration of Highlight into your Rails application is straightforward, allowing developers to highlight code snippets easily with minimal setup. This ensures that regardless of your coding environment, you can enhance the readability of your code with vibrant and accurate syntax highlighting.

Features

• Wide Language Support: Highlight supports many languages including Ruby, JavaScript, Python, and more, catering to various coding styles and preferences.

• Fallback Option: If Pygments is not installed, Highlight automatically utilizes a web API, ensuring functionality without any complex configurations.

• Simple Integration: Adding Highlight to your Rails application is easy; a simple entry in the Gemfile is all it takes to get started.

• Caching for Performance: To improve speed, all highlighted source code can be cached, reducing the load time for frequent usage.

• Default CSS Styles: Highlight comes with a default CSS file, allowing you to customize the appearance of highlighted code easily.

• Block Usage: Code can be passed to the highlight method either as a string or within a block, offering flexibility in how you use the gem.

• Easy Installation: The setup process is user-friendly, ensuring that both Ruby and Rails developers can implement it with minimal effort.

Highlight empowers developers to present their code gracefully, blending functionality with ease of use.
