# Gradle

## Debugging Gradle Tasks From IntelliJ

You need to make sure the task is not running in the Gradle daemon.

# Grav

## Using a twig extension function in the plugin itself

```php
public function onTwigExtensions()
{
    $this->grav['twig']->twig()->addFunction(
        new \Twig_SimpleFunction('forms', [$this, 'getForm'])
        );
    }
}

public function getForm($e)
{
}
```

## Using a twig extension class

```php
public function onTwigExtensions()
{
    require_once(__DIR__ . '/twig/twig-extensions.php');
    $this->grav['twig']->twig->addExtension(new GitTwigExtensions($this->grav));
}
```

## Routes

Grav routes always begin with `/`.

To referer to a route in a twig, always use `base_url ~ p.route`.

For edit page, it would be `base_url ~ '/admin/pages' ~ p.route`.

# OSGi

## Using the diag command to find missing references

## Adding a command to Gogo

```kotlin
@Component(service = [Command::class], property = ["osgi.command.scope=myscope", "osgi.command.function=doIt"])
class Command {
    fun doIt() {
    }
}
```

# Mocha / NPM
