Guileless

Guileless is a naive HTML preprocessor. It does three things:

1. Single line breaks are converted to <br>
2. Several consecutive line breaks are treated as paragraphs and wrapped in <p>
3. Converts stray <, >, and &s to character entities.

Why is this more useful than, say, Rails' built in simple_format?

Well, it's actually a real (if simplistic) HTML parser. It understands nested tags, and will happily format text nodes inside divs and blockquotes.

Valid HTML is assumed, and it doesn't do any sanitation on the input. Anything it doesn't need to understand is simply passed through, but mismatched or missing opening and closing tags on block level elements will break.

Installation

gem install guileless

or add it to your gemfile:

gem "guileless"

Usage

Guileless.format("<div>foo</div>") # => "<div><p>foo</p></div>"
