properties is a Go library for reading and writing properties files.
It supports reading from multiple files and Spring style recursive property
expansion of expressions like ${key} to their corresponding value.
Value expressions can refer to other keys like in ${key} or to
environment variables like in ${USER}.
Filenames can also contain environment variables like in
/home/${USER}/myapp.properties.
The properties library supports both ISO-8859-1 and UTF-8 encoded data.
Starting from version 1.3.0 the behavior of the MustXXX() functions is
configurable by providing a custom ErrorHandler function. The default has
changed from panic to log.Fatal but this is configurable and custom
error handling functions can be provided. See the package documentation for
details.
import "github.com/magiconair/properties"
func main() {
p := properties.MustLoadFile("${HOME}/config.properties", properties.UTF8)
host := p.MustGetString("host")
port := p.GetInt("port", 8080)
