## What it is
Mustache is the canonical Ruby implementation of the logic-less Mustache template language, separating markup templates from Ruby view classes. It renders HTML (or any text) by referencing methods on a view class, with no application logic allowed in templates.

## Use cases
- render html templates in ruby without embedding logic
- replace erb or haml views with logic-less templates
- separate presentation from application logic in a ruby web app
- generate emails or documents from templates in ruby
- test view logic independently of markup

## When to choose
- you want strict separation of markup and logic in a Ruby project
- you need a simple, framework-agnostic templating gem
- you prefer view classes over inline Ruby in templates

## When to avoid
- you need conditional logic, filters, or macros inside templates
- you want a full-featured engine like ERB, Haml, or Liquid
- you are not working in Ruby (use a Mustache implementation for your language instead)

## Facets
- artifact type: library
- maturity: stable
- function: templating
- domain: web-development, frontend, developer-tools
- platform: ruby, cross-platform
