# Migrant [](https://travis-ci.org/jaemk/migrant) [](https://crates.io/crates/migrant) [](https://crates.io/crates/migrant_lib) [](https://docs.rs/migrant_lib)
> Basic migration manager powered by [`migrant_lib`](https://github.com/jaemk/migrant/tree/master/migrant_lib)
Currently supports:
* postgres
* sqlite
`migrant` will manage all migrations that live under `<project-dir>/migrations/` where `project-dir` is `.../<project-dir>/.migrant.toml`.
The default migration location can be modified in your `.migrant.toml` file (`"migration_location"`).
If the 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`).
The binary releases are built with all features.
See [releases](https://github.com/jaemk/migrant/releases) for binaries, or
```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 initial` - Generate new up & down files with the tag `initial` under the specified `migration_location`.
`migrant edit initial [--down]` - Edit the `up` [or `down`] migration file with the tag `initial`.
`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
### Usage as a library
See [`migrant_lib`](https://github.com/jaemk/migrant/tree/master/migrant_lib) and [examples](https://github.com/jaemk/migrant/tree/master/migrant_lib/examples)
### Development
- Install dependencies: `sqlite3`, `libsqlite3-dev`, `postgresql`, `libpq-dev`
- `./test_all.sh`
