Sprig is a comprehensive library of helper functions designed to extend the Go text template engine. It provides a wide array of custom functions that can be injected into the engine to enable complex data manipulation and logic directly within templates.
The project offers specialized capabilities for cryptography, including the generation of private keys, X.509 certificates, and secure password hashes. It also includes advanced logic extensions for semantic versioning comparison, ternary evaluations, and the resolution of environment variables from the host operating system.
The library covers a broad surface of general-purpose utilities, including extensive string processing for case conversion and regular expressions, mathematical operations for floating-point and integer arithmetic, and temporal tools for date and time formatting. It further provides data structure management for deeply merging dictionaries, filtering lists, and encoding or decoding JSON.
The project is implemented as a function map that integrates with the standard Go template system.
