Scratch

A tiny BSON database in Golang, a drop-in replacement for scribble.

Installation

Install using go get git.sdf.org/Atlas48/scratch.

Usage

// a new scratch driver, providing the directory where it will be writing to,
// and a qualified logger if desired
db, err := scratch.New(dir, nil)
if err != nil {
  fmt.Println("Error", err)
}

// Write a fish to the database
fish := Fish{}
if err := db.Write("fish", "onefish", fish); err != nil {
  fmt.Println("Error", err)
}

// Read a fish from the database (passing fish by reference)
onefish := Fish{}
if err := db.Read("fish", "onefish", &onefish); err != nil {
  fmt.Println("Error", err)
}

// Read all fish from the database, unmarshaling the response.
records, err := db.ReadAll("fish")
if err != nil {
  fmt.Println("Error", err)
}

fishies := []Fish{}
for _, f := range records {
  fishFound := Fish{}
  if err := json.Unmarshal([]byte(f), &fishFound); err != nil {
    fmt.Println("Error", err)
  }
  fishies = append(fishies, fishFound)
}

// Delete a fish from the database
if err := db.Delete("fish", "onefish"); err != nil {
  fmt.Println("Error", err)
}

// Delete all fish from the database
if err := db.Delete("fish", ""); err != nil {
  fmt.Println("Error", err)
}
