Prism

Prism is a JavaScript syntax highlighter and web-based code formatter. It functions as an extensible syntax engine designed to colorize and format code blocks on web pages, making various programming languages easier to read.

The project processes raw code strings into styled HTML elements for use in frontend content rendering, technical documentation, and static site generation. It provides a modular system for adding custom language definitions and highlighting rules to a web-based code viewer.

Features

  • Syntax Highlighters - Renders code snippets with color-coded syntax highlighting to make technical content readable.
  • Lexical Tokenizers - Uses regular expression patterns to break source code into a stream of meaningful tokens.
  • Language Support Definitions - Provides a modular system to define grammars and patterns for supporting various programming languages.
  • Code-to-HTML Rendering - Processes raw code strings into styled HTML elements for browser-based display.
  • Client-Side Code Formatters - Processes and styles source code directly in the browser for consistent visual presentation.
  • Syntax Highlighting Engines - Provides a modular system for defining and rendering custom language syntax and styling rules.
  • Technical Documentation Styling - Adds visual syntax highlighting to technical documentation and blog posts.
  • Recursive Grammar Matching - Matches nested language structures by recursively applying grammar rules to tokens.
  • Single-Pass Tokenizers - Processes input strings in a single pass without maintaining complex internal state between blocks.
  • CSS Class-Based Styling - Uses semantic class names to delegate token colorization to external CSS stylesheets.
  • Token Wrapping - Wraps identified code tokens in HTML span elements for browser-based styling.
  • Development Tools - Lightweight syntax highlighter for displaying code snippets in documentation.
  • Syntax Highlighting - Lightweight and robust syntax highlighter.
