Treasure Map

A collection of go template functions. Some functions are inspired by helm, i.e. include and tpl.

Usage

Some function require to close over the template itself. Therefore, the MakeFuncMap function takes the template as argument and returns the fully constructed map. In the below example sprigs TxtFuncMap is passed as base map.

import (
    "testing"
    "text/template"

    "github.com/Masterminds/sprig/v3"
    "github.com/bluebrown/treasure-map/textfunc"
)

func main() {
    tpl := template.New("")
    tpl.Funcs(textfunc.MapClosure(sprig.TxtFuncMap(), tpl))
}
