Lancet is a comprehensive utility function library for Go that provides reusable helpers across multiple domains.
The library addresses the need for a centralized collection of common utility functions in Go, drawing inspiration from Java's Apache Commons and JavaScript's Lodash. It organizes functionality into focused packages covering strings, slices, datetime operations, networking, cryptography, file handling, and many other domains. By bundling these utilities into a single library with consistent APIs, developers avoid reimplementing the same logic across projects. The tool leverages Go's generics feature to provide type-safe implementations while maintaining minimal external dependencies, relying only on the Go standard library and golang.org packages.
Lancet suits projects that need frequent utility operations and want to reduce boilerplate code. It works best for teams already familiar with utility libraries from other languages who want similar convenience in Go. The library provides broad coverage across algorithm, comparison, concurrency, data conversion, cryptography, datetime, file operations, validation, and data structure manipulation. Developers should note that the project requires Go 1.18 or later to access the generics-based implementations that form the current version.
The project maintains comprehensive test coverage for every exported function. Development activity shows consistent attention to code quality and reliability through systematic testing practices.
