A library written in Go for matching user agent strings against the devices in WURFL Database. Documentation on godoc.org

Assuming that you have set up go,

Just run

go get github.com/srinathgs/wurflgo

Then create the binary,

cd $GOPATH/src/github.com/srinathgs/wurflgo/parser/
go build parser.go

Download wurfl.xml from WURFL Download Page

Run the parser with the following command.

./parser -groups product_info,xhtml_ui -input <path to input directory>/wurfl.xml -output <output directory>/wurfl.go

You can specify all the groups you need separated by commas to the groups flag(Check wurfl.xml for the available groups). No need of spaces in between them.

Then you are set to match the devices.

Keep the wurfl.go file in your project directory and wherever you want to look up the device capabilities from the User-Agent string,

...
...
import "github.com/srinathgs/wurlfgo"
...
...

func foobar(w http.ResponseWriter, r *http.Request){
  device := wurflgo.Match(r.UserAgent())
}

then build your project with the following command

go build wurfl.go <your file>.go

It takes a bit of time and it generates the binary. wurfl.go file generated has a lot of lines of code depending upon what you have selected in groups. So, go build needs a lot of memory (only during build time) to generate the binaries. If the machine on which go build was run did not have enough memory, go build will hang.

Contributions are welcome!
