Overview
Current version: 1.7.0
properties is a Go library for reading and writing properties files.
It supports reading from multiple files or URLs 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
.
Properties can be decoded into structs, maps, arrays and values through struct tags.
Comments and the order of keys are preserved. Comments can be modified and can be written to the output.
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.
Getting Started
import (
"flag"
"github.com/magiconair/properties"
)
func main() {
p := properties.MustLoadFile("${HOME}/config.properties", properties.UTF8)
// via getters
host := p.MustGetString("host")
port := p.GetInt("port", 8080)
// or via decode
type Config struct {
Host string `properties:"host"`
Port int `properties:"port,default=9000"`
Accept []string `properties:"accept,default=image/png;image;gif"`
Timeout time.Duration `properties:"timeout,default=5s"`
}
var cfg Config
if err := p.Decode(&cfg); err != nil {
log.Fatal(err)
}
// or via flags
p.MustFlag(flag.CommandLine)
// or via url
p = properties.MustLoadURL("http://host/path")
}
