Lancet Project Overview

Introduction

Lancet is an extensive, efficient, and reusable utility function library designed for the Go programming language. It draws inspiration from well-known libraries such as Java Apache Commons and lodash.js, aiming to enhance Go's functionality by providing a comprehensive toolkit of over 700 utility functions. These functions are designed to assist developers in handling strings, slices, datetime operations, networking, cryptography, and more.

Features

• Comprehensive and Efficient: Lancet offers a wide array of functions that cater to different programming needs, ensuring efficiency and reusability.
• Broad Functionality: The library encompasses more than 700 Go utility functions that span various domains including string manipulation, slice operations, datetime handling, network functions, and encryption.
• Minimal Dependencies: The library primarily relies on the Go standard library and golang.org/x packages, reducing the need for external dependencies.
• Unit Testing: Every exported function in Lancet is accompanied by unit tests, ensuring reliability and robustness of the codebase.

Installation

Lancet supports Go 1.18 and above, utilizing Go's generics for better performance and code simplicity. Users working with Go 1.18 and newer should install the latest v2.x.x version:

go get github.com/duke-git/lancet/v2

For those using earlier versions of Go, the latest compatible version is v1.4.4:

go get github.com/duke-git/lancet

Usage

The library is organized into package structures, requiring the import of specific packages for accessing related functions. For instance, to use string-related functions, you need to import the strutil package:

import "github.com/duke-git/lancet/v2/strutil"

Example Code

Here is a simple example demonstrating how to reverse a string using Lancet:

package main

import (
    "fmt"
    "github.com/duke-git/lancet/v2/strutil"
)

func main() {
    s := "hello"
    rs := strutil.Reverse(s)
    fmt.Println(rs) // Output: olleh
}

Documentation

Lancet is neatly arranged into different packages like Algorithm, Compare, Concurrency, and many more, each designed to handle specific types of operations. For example:

• Algorithm: Contains basic algorithm implementations like sorting and searching.
• Compare: Offers comparison functions that can handle various data types.
• Concurrency: Provides functions to facilitate concurrent programming, supporting goroutines and channels.

Each package includes detailed documentation and examples to guide developers in effectively utilizing the functions provided by Lancet.

Conclusion

Lancet is an invaluable resource for Go developers seeking to streamline their development process with ready-to-use utility functions. Its broad range of features and simplicity of integration make it a must-have library for any modern Go developer.

Whether it's manipulating strings, handling larger datasets, or working with algorithms, Lancet equips you with everything needed to improve code efficiency and maintainability in your Go projects.
