})
}
Example #2
You can use <$- to strip white spaces before the code block and
-$> to strip white spaces after the code block.
Also omitting the print statement for simple evaluations is possible.
package main
import (
"os"
"github.com/Eun/yaegi-template"
"github.com/traefik/yaegi/interp"
"github.com/traefik/yaegi/stdlib"
)
func main() {
template := yaegi_template.MustNew(interp.Options{}, stdlib.Symbols)
template.MustParseString(`
<html>
<p>
<$-
context.UserName
-$>
</html>
`)
type Context struct {
LoggedIn bool
UserName string
}
template.MustExec(os.Stdout, &Context{
LoggedIn: true,
UserName: "Joe Doe",
})
}
