tplutil

Overview ¶

Package tplutil provides more convient way to use text/template inside the code.

Consider (using text/template):

var myTpl = template.Must(template.New("name").Parse(
	"Some list:\n" +
		"{{range .}}" +
		"# {{.}}\n" +
		"{{end}}"))

`gofmt` will ruin any attempt to format code above.

And with tplutil:

var myTpl = template.Must(template.New("name").Parse(tplutil.Strip(`
	Some list:{{"\n"}}

	{{range .}}
		# {{.}}{{"\n"}}
	{{end}}
`)))

Output will be exactly the same.

Any indenting whitespaces and newlines will be ignored. If must, they should be specified by using syntax

`{{" "}}` or `{{"\n"}}`.

It also provide `{{last}}` function to check on last element of pipeline:

var myTpl = template.Must(template.New("asd").Funcs(tplutil.Last).Parse(
	tplutil.Strip(`
		Some list:{{"\n"}}

		{{range $i, $_ := .}}
			{{.}}
			{{if not (last $i $)}}
				{{"\n"}}{{/* do not append newline to the last element */}}
			{{end}}
		{{end}}
	`))
