SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a secure method for processing user-editable templates that contain conditional logic, preventing arbitrary code execution vulnerabilities.

Core Features & Use Cases

  • Safe Conditional Logic: Parses {{#if ...}}...{{/if}} blocks using regex, avoiding eval().
  • Operator Precedence: Correctly handles && and || operators for complex conditions.
  • Use Case: Securely render personalized email templates where users can define basic conditional content without risking security breaches.

Quick Start

Use the safe-template-dsl skill to process the template string 'Hello {{name}}!' with the provided variables.

FAQPage Schema
How do I parse user-editable templates with conditional logic without using eval()?

To parse user-editable templates without eval(), use regex-based parsing to process conditional blocks and variable substitution. This approach securely handles complex conditions with operator precedence while ensuring fail-safe evaluation for unknown expressions.

What is the best way to securely render personalized email templates containing conditional content?

The best way to securely render personalized email templates is using regex-based parsing for conditional blocks like {{#if}}. This prevents arbitrary code execution vulnerabilities while allowing users to define basic conditional content safely.

Does this template parsing approach support complex conditions with operator precedence?

Yes, this template parsing approach supports complex conditions with operator precedence. It correctly handles && and || operators within conditional blocks, ensuring accurate evaluation of multi-part logical expressions during rendering.

How do template variables get substituted during secure template rendering?

Template variables are substituted during secure template rendering through regex-based parsing. The system replaces variable placeholders with provided values while processing conditional logic, ensuring fail-safe evaluation for any unknown expressions encountered.

Can I use safe-template-dsl for processing user-editable templates in PHP applications?

Yes, you can use safe-template-dsl for processing user-editable templates in PHP applications. It securely parses conditional logic blocks and performs variable substitution without eval(), preventing arbitrary code execution vulnerabilities in user-defined content.

What happens when unknown expressions are encountered during conditional logic evaluation?

When unknown expressions are encountered during conditional logic evaluation, the system ensures fail-safe evaluation. This prevents rendering errors and maintains security by safely handling unrecognized variables or conditions within the template blocks.
