Overview ¶
Package dpkg contains routines to parse Debian package information.
Example:
package main
import (
"fmt"
"os"
dpkg "maze.io/dpkg.v1"
)
func main() {
db, err := dpkg.Open()
if err != nil {
fmt.Fprintf(os.Stderr, "dpkg open failed: %v\n", err)
os.Exit(1)
}
fmt.Println("installed packages:")
for _, pkg := range db.PackagesWithStatus("installed") {
fmt.Printf("%s-%s\n", pkg.Name, pkg.Version)
}
}
