- Change Down(n<=0) to mean "rollback all" (matching Up semantics). CLIs now explicitly pass 1 when no count is given. - Add 22 tests for Collect, NamesOnly, Up, Down, and GetStatus using mock Migrator and fstest.MapFS. - Fix shmigrate.Applied to stream from file instead of ReadFile double-wrap; add optional FS field for embed.FS support. - Update package doc to list all 5 backends. - Add minimal README linking to pkg.go.dev.
sqlmigrate
Database-agnostic SQL migration library for Go.
Backend packages
Each backend is a separate Go module to avoid pulling unnecessary drivers:
| Package | Database | Driver |
|---|---|---|
| pgmigrate | PostgreSQL | pgx/v5 |
| mymigrate | MySQL / MariaDB | go-sql-driver/mysql |
| litemigrate | SQLite | database/sql (caller imports driver) |
| msmigrate | SQL Server | go-mssqldb |
| shmigrate | Shell scripts | (generates POSIX sh) |
CLI
The sql-migrate CLI uses shmigrate to generate shell scripts for managing migrations without a Go dependency at runtime.
