A Delphi and Free Pascal implementation of the Mustache templating language with extensions and high performance.
SynMustache is a Delphi and Free Pascal (FPC) implementation of the Mustache logic-less templating language. It provides a robust, high-performance template engine that is fully compliant with the official Mustache specification while adding useful extensions like pseudo-variables, pseudo-sections, and expression helpers. It solves the problem of needing a reliable, efficient templating solution for Delphi applications, especially in web development contexts.
Delphi and Free Pascal developers who need a Mustache-compliant template engine for building dynamic content, particularly those working with the mORMot framework for MVC web development. It is also suitable for developers requiring a standalone, performance-optimized templating library.
Developers choose SynMustache because it is the first Delphi implementation to pass all official Mustache specification tests, ensuring strict compliance, while offering performance optimizations like minimal memory allocation and UTF-8 native support. Its unique selling point includes seamless integration with mORMot and extensibility through SOLID design principles, allowing customization for various data contexts.

Passes all official Mustache specification tests, including whitespace handling, ensuring reliable and predictable template behavior across implementations.
Optimized for minimal memory allocation during rendering with UTF-8 native support, leveraging SynCommons for efficient execution in resource-sensitive applications.
Supports data input as JSON or TDocVariant custom variants, allowing seamless integration with various data sources in Delphi projects without complex conversions.
Adds pseudo-variables (e.g., {{-index}}), pseudo-sections (e.g., {{#-first}}), and expression helpers, enhancing Mustache for practical use cases like list indexing and conditional logic.
Tightly integrated with the Synopse ecosystem, requiring SynCommons.pas and other units even for standalone use, which can complicate setup and increase dependency management.
Exclusively for Delphi and Free Pascal, making it unsuitable for cross-language projects or developers working in other programming environments.
Documentation is spread across PDFs, blog posts, and mORMot SAD, with README notes that PDFs can be outdated, potentially hindering the learning curve.
