Nushell Plugin in GoLang

This is a base library for generating a nushell plugin in Golang. As nushell is under development, it's likely that not all features are implemented here! Please open an issue if you need help.

Filter Plugin

I've done a basic filter example to calculate the length of a string, and the usage is summarized as follows:

package main
 
import nu "github.com/vsoch/nu-plugin/pkg/plugin"


// filter will read stream from nushell and print a response
func filter(plugin *nu.FilterPlugin, params interface{}) {

	// can also be getIntPrimitive
	value := plugin.Func.GetStringPrimitive(params)

	// Put your logic here! In this case, we want a length
	intLength := len(value)

	// You must also return the tag with your response
	tag := plugin.Func.GetTag(params)

	// This can also be printStringResponse
	plugin.Func.PrintIntResponse(intLength, tag)

}


func main() {

	name := "len"
	usage := "Return the length of a string"
	plugin := nu.NewFilterPlugin(name, usage)

	// Run the filter function
	plugin.Run(filter)
}

Sink Plugin

We have two examples for Sink plugins:

• examples/salad prints colored salad puns to the screen
• examples/hello is a more basic example to say hello
