Haml is a Ruby templating engine that compiles an indentation-based, DRY markup language into HTML, usable from the command line or within Ruby web frameworks like Rails. It eliminates redundant closing tags and boilerplate, embedding Ruby code for dynamic content.
Use cases
- write cleaner HTML templates for a Rails app
- replace ERB templates with more readable markup
- render HTML documents from the command line
- reduce repetition in HTML view code
- embed Ruby logic in page templates
When to choose
- you're on Ruby/Rails and want concise, well-indented templates
- you find ERB verbose and error-prone
- your team values readable, structured markup
When to avoid
- your project is not in Ruby
- your team is unfamiliar with indentation-sensitive syntax
- you need templates shared with non-Ruby tooling
