Installation
------------

[](#installation)

AstronomyLibrary can be installed via composer. laravel-astronomy-library needs at least php 7.4 to run.

```
composer require deepskylog/laravel-astronomy-library
```

You need to publish and run the migration:

```
php artisan vendor:publish --provider="deepskylog\AstronomyLibrary\AstronomyLibraryServiceProvider" --tag="migrations"
php artisan migrate
```

### Applying migrations (package users)

[](#applying-migrations-package-users)

When installing the package you need to publish the package migration stubs into your application and run your migrations.

- Fresh install (no existing `comets_orbital_elements` table):

```
php artisan vendor:publish --provider="deepskylog\AstronomyLibrary\AstronomyLibraryServiceProvider" --tag="migrations"
php artisan migrate
```

- Existing install (table already present):

1. Publish the package migrations (this copies an ALTER migration stub into your app):

```
php artisan vendor:publish --provider="deepskylog\AstronomyLibrary\AstronomyLibraryServiceProvider" --tag="migrations"
```

1. Run your migrations. The published ALTER migration will add the optional photometry columns (`H`, `n`, `phase_coeff`, `n_pre`, `n_post`) if they don't already exist:

```
php artisan migrate
```

Note: the package includes both a create-table stub (for new installs) and a safe ALTER stub (for existing installs); publishing then migrating is the recommended flow in both cases.

The database table with the delta t values can be updated using the following command:

```
php artisan astronomy:updateDeltat
```

A job is automatically scheduled every 4 months to update the delta t value.

The database tables with the orbital elements of the comets and the asteroids can be updated using the followong command:

```
php artisan astronomy:updateOrbitalElements
```

A job is automatically scheduled every Monday at 04:30 to update the orbital elements of the comets and the asteroids.

These jobs can be executed using:

```
php artisan schedule:run
```

It is possible to run these jobs automatically by adding the following line to your crontab:

```
* * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1
```
