Climate is a CLI library for Go that aims to simplify the process of creating command-line interfaces. Inspired by python-fire, Climate is built on top of Cobra and comes with "batteries included," providing features such as help generation, shell completion, and more.

With Climate, developers can easily autogenerate CLIs from structs and functions, with support for nested subcommands and global/local flags. The library also offers typo suggestions and allows for easy generation of help documentation from godocs.

To demonstrate the usage of Climate, here's an example code snippet:

package main

import (
	"fmt"
	"github.com/avamsi/climate"
)

func main() {
	app := climate.NewCliMate()
	app.Command("greet", "Greet someone", func(c *climate.CliMate) {
		name := c.String("name", "World", "The name of the person to greet")
		c.Action(func() {
			fmt.Printf("Hello, %s!\n", *name)
		})
	})

	app.Run()
}

Climate provides a seamless experience for developers looking to create CLIs in Go. It simplifies the process and offers a range of features that make CLI development more efficient and enjoyable. With its intuitive interface and extensive documentation, Climate is a valuable tool for developers looking to keep up with the latest trends in the industry.
