Migrant

Build Status crates.io:migrant

Basic migration manager powered by migrant_lib

Currently supports: * postgres * sqlite

migrant will manage all migrations that live under <project-dir>/migrations/ where project-dir is the closest parent path that contains a .migrant.toml configuration file (..../<project-dir>/.migrant.toml). The default migration file location can be modified in your .migrant.toml file ("migration_location"). If the migration_location directory doesn't exist, it will be created the first time you create a new migration. migrant stores all applied migrations in a database table named __migrant_migrations

Installation

By default migrant will build without any features, falling back to using each database's cli commands (psql & sqlite3). The postgres and rusqlite database driver libraries can be activated with the postgresql and sqlite features. Both of these drivers require their dev libraries (postgresql: libpq-dev, sqlite: libsqlite3-dev). Self update functionality (updating to the latest GitHub release) is available behind the update feature. The binary releases are built with all features.

See releases for binaries. If you've installed a binary release, you can update to the latest release via migrant self update.

Install from source/crates.io:

```shell

install without features

use cli commands for all db interaction

cargo install migrant

install with postgres

cargo install migrant --features postgresql

install with rusqlite

cargo install migrant --features sqlite

all

cargo install migrant --features 'postgresql sqlite' ```

Simple Usage

migrant init [--type <database-type>, --location <project-dir>, --no-confirm] - Initialize project by creating a .migrant.toml file with db info/credentials. When run interactively (without --no-confirm), setup will be run automatically.

migrant setup - Verify database info/credentials and setup a __migrant_migrations table if missing.

migrant new <tag> - Generate new up & down files with the given <tag> under the specified migration_location.

migrant edit <tag> [--down] - Edit the up [or down] migration file with the given <tag>.

migrant list - Display all available .sql files and mark those applied.

migrant apply [--down, --all, --force, --fake] - Apply the next available migration[s].

migrant shell - Open a repl

migrant which-config - Display the full path of the .migrant.toml file being used

migrant connect-string - Display either the connection-string generated from config-params or the database-path for sqlite

migrant self update - Update to the latest version released on GitHub.

migrant self bash-completions install [--path <path] - Generate a bash completion script and save it to the default or specified path.

Usage as a library

See migrant_lib and examples. migrant itself is just a thin wrapper around migrant_lib, so the full functionality of migration management can be embedded in your actual project.
