Test string template with list0 data

package main

import (
	"os"
	"text/template"

	"github.com/go-easygen/easygen"
)

var tmpl *template.Template

	// Equivalent testing on commandline:
	//   easygen -ts '{{range .Colors}}{{.}}, {{end}}' test/list0
	easygen.Process0(tmpl, os.Stdout,
		"{{range .Colors}}{{.}}, {{end}}", "test/list0")
}

Output:

red, blue, white,

}

Output:

[red blue white]

Test the string split function in template again

package main

Test string comparison in template

package main

import (
	"os"
	"text/template"

	"github.com/go-easygen/easygen"
