Opinionated Go package for loading templates with default functions.
package main
import (
"bufio"
"bytes"
"context"
"embed"
"github.com/sfomuseum/go-template/html"
"strings"
)
//go:embed html_test.html
var FS embed.FS
func main() {
ctx := context.Background()
tpl, _ := html.LoadTemplates(ctx, FS)
test_t := tpl.Lookup("test")
type TestVars struct {
PageTitle string
}
vars := TestVars{
PageTitle: "This is a test",
}
var buf bytes.Buffer
wr := bufio.NewWriter(&buf)
test_t.Execute(wr, vars)
}
Where html_test.html looks like this:
{{ define "test"}}
<html>
<head>
<title>{{ if (IsAvailable "PageTitle" .) }}{{ .PageTitle }}{{ end }}</title>
</head>
<body>{{ if (IsAvailable "UserName" .) }}Hello {{ .UserName }}{{ else }}This is a test.{{ end }}
</body>
</html>
{{ end }}
