What it is

Shopify/liquid is a secure, stateless template engine written in Ruby that renders Liquid markup (a Smarty-inspired syntax with {{ variables }} and {% tags %}) without executing arbitrary code. It's designed for customer-facing templates in web applications, supporting filters, loops, conditionals, and custom blocks while maintaining strict sandboxing—templates compile once and render many times with different data contexts. Monolithic lib/ structure: lib/liquid.rb is the entry point, with core parsing in lib/liquid/lexer.rb and lib/liquid/parser.rb, tag/filter definitions spread across lib/liquid/*.rb files (e.g., lib/liquid/block.rb for block tags, lib/liquid/standardfilters.rb for…

Start here

• lib/liquid.rb: Main entry point; loads all core modules and exports public API (Template, Environment, Context)
• lib/liquid/environment.rb: Central configuration object; where custom tags, filters, and security policies are registered…
• lib/liquid/lexer.rb: Tokenizes raw Liquid markup into tokens; critical for secure parsing without eval
• lib/liquid/parser.rb: Builds Abstract Syntax Tree from lexer tokens; validates syntax and creates executable nodes
• lib/liquid/context.rb: Manages variable scopes, filters, and data binding during template rendering

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/Shopify/liquid.git
cd liquid
bundle install
bundle exec rake test

(Gemfile present; bin/render executable suggests a CLI interface for testing templates)

Daily commands:

bundle exec rake test          # Run full test suite
bundle exec bin/render FILE   # Parse and render a .liquid file
cd example/server && ruby server.rb  # Start demo web server

Key cautions & unknowns

• 1. Environment isolation: Custom tags/filters added to a global Liquid::Template class will leak across all templates—use Liquid::Environment per-context instead (mentioned in README). 2. **File system…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
