### `dependencies` and `dev-dependencies`

## `dependencies` and `dev-dependencies`

Poetry is configured to look for dependencies on [PyPi](https://pypi.org) by default.

Only the name and a version string are required in this case.

    [tool.poetry.dependencies]

    python = "^3.6"

    ```

## `scripts`

This section describe the scripts or executable that will be installed when installing the package

```toml

[tool.poetry.scripts]

poetry = 'poetry:console.run'

```

Here, we will have the `poetry` script installed which will execute `console.run` in the `poetry` package.

## `extras`

Poetry supports extras to allow expression of:

* optional dependencies, which enhance a package, but are not required; and

* clusters of optional dependencies.

```toml

[tool.poetry]

name = "awesome"

[tool.poetry.dependencies]

# These packages are mandatory and form the core of this package’s distribution.

mandatory = "^1.0"

# A list of all of the optional dependencies, some of which are included in the

# below `extras`. They can be opted into by apps.

psycopg2 = { version = "^2.7", optional = true }

mysqlclient = { version = "^1.3", optional = true }

[tool.poetry.extras]

mysql = ["mysqlclient"]

pgsql = ["psycopg2"]

```

When installing packages, you can specify extras by using the `-E|--extras` option:

```bash

poetry install --extras "mysql pgsql"

poetry install -E mysql -E pgsql

```

## `plugins`

Poetry supports arbitrary plugins wich work similarly to

[setuptools entry points](http://setuptools.readthedocs.io/en/latest/setuptools.html).

To match the example in the setuptools documentation, you would use the following:

```toml

[tool.poetry.plugins] # Optional super table

[tool.poetry.plugins."blogtool.parsers"]

".rst" = "some_module::SomeClass"

```
