When developers or creators refer to “Craig’s Text-to-HTML tool” in the context of fast coding and lightweight syntax, they are typically referring to Rainbow, a remarkably lightweight, extensible code syntax highlighter and string/text transformer created by developer Craig Campbell (hosted on his primary utility site at craig.is/making/rainbows).

While traditional WYSIWYG text-to-HTML engines focus on turning plain text paragraphs into document structures, Craig’s tool focuses on the fastest way to safely embed, convert, and highlight block code snippets into clean HTML format for documentation, blogs, or fast prototyping. Key Features of Craig’s Tool

Ultra-Lightweight Footprint: The entire core script is only about 1.4kb, meaning it won’t bloat your fast-coded web projects.

Extensible Architecture: You only need to load the generic background scripts and the specific language pack (like HTML, CSS, JavaScript, or Python) you are targeting.

No Manual Tag Escaping: Instead of manually typing tedious HTML entities like < and >, the engine dynamically reads raw block text and processes it safely into validated HTML spans on the fly. Step-by-Step Guide to Use It for Fast Coding 1. Link the Core Architecture

First, include the core script and your choice of coding theme inside the tag of your HTML structure. You can use standard local files or load them instantly to keep development fast.

Use code with caution. 2. Include Your Specific Language Sub-Pack

To keep the execution lightning-fast, Craig’s tool requires you to only load the syntax languages you actually use. Add your chosen language components right after the core script:

Use code with caution. 3. Write Plain Text and Let the Script Convert It

To output rapid HTML blocks without writing nested elements or styling rows yourself, wrap your raw text/code block using a standard

 tag containing a  element. Use the data-language attribute to tell the engine how to convert it:
