# Go migrations
A very simple migration library for your Go projects.
```go
import "github.com/felix/go-migrate"
```
or
```go
import "src.userspace.com.au/felix/go-migrate"
```
## Features
- Any database/sql drivers should work. See https://github.com/golang/go/wiki/SQLDrivers
- Each migration is run in a transaction so there should be no 'dirty' state.
- Only migrates "up". I have never used a "down" migration.
- Enables a callback function to suit whatever logging implementation you choose.
## Usage
```go
db, err := sql.Open("pgx", uri)
//db, err := sql.Open("sqlite3", uri)
if err != nil {
return err
}
defer db.Close()
// Relative path to migration files
migrator, err := migrate.NewFileMigrator(db, "file://migrations/")
if err != nil {
return fmt.Errorf("failed to create migrator: %s", err)
}
// Migrate all the way
err = migrator.Migrate()
if err != nil {
return fmt.Errorf("failed to migrate: %s", err)
}
v, err := migrator.Version()
fmt.Printf("database at version %d\n", v)
```
