template-extract

A Library for extracting placeholders from the templates.

Getting Library

Install the library with

go get -u "github.com/MeowSaiGithub/template-extract

Import the library

import te "github.com/MeowSaiGithub/template-extract"

How to use

        t, err := template.New("test").Parse("Hello {{.Name}}")
	if err != nil {
		panic(err)
	}
	td, _ := te.NewTemplateDataExtractor(t)
	td.ExtractPlaceHolders()
	fmt.Println(td.GetRawData())
	fmt.Println(td.GetCleanData())
	fmt.Println(td.GetMapData())

Raw Data is every action placeholders such as {{.Name}}, {{$name := .Name}}.

Clean Data is only Name from both data of above. It removed duplicated data and remove un-necessary strings.

Map data is map["Name": ""]. This can be used for json marshalling and unmarshalling the request data.
