ytt (YAML Templating Tool)

ytt is a templating tool that understands YAML structure allowing you to focus on your data instead of how to properly escape it.

Features:

• templating works on YAML structure (instead of text)
  • eliminates variety of problems such as invalid YAML formatting, escaping, etc.
• syntactic sugar for single YAML node conditionals and for loops
  • makes it easier to read densely conditioned templated
• templates are themselves valid YAML files
  • makes them friendly to existing editors and YAML tools
• includes sandboxed "fully featured" Pythonic programming language
  • compared to what's exposed in go/template for example
