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.
