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.
