FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package scheduler
Flow & Neos Task Scheduler
A basic tasks scheduler inspired by cron for your Flow and Neos project.
Create a Task object
You need to implement the Ttree\Scheduler\Task\TaskInterface::
Dynamic Tasks
You can schedule your own Task object, by adding a `Ttree\Scheduler\Annotations\Schedule annotation to your class::
This task will be executed every minute. Dynamic task do not support arguments, the $arguments of the execute method
is always an empty array.
If your expression contains slashes, you have to double-escape them. I.e. run the task every 5 minutes: @Scheduler\Schedule(expression="*\\/5 * * * *")
You can also add a description to your task using the Meta annotation::
Persisted Tasks
You can also create persisted tasks. Persisted tasks support execution argument. You can register the same task object multiple times, if your arguments are different between each task. You can pass a valid JSON arguments array:
flow task:register --expression "* */3 * * *" --task "Ttree\Aggregator\Task\AggregatorTask" --arguments '{"node": "af97b530-0c70-7b87-3cf4-f9a611f88c18"}'Available Configuration Options
| Option | Default | Description |
|---|---|---|
| allowParallelExecution | true | If the scheduler command is executed while the scheduler is already running tasks, the second scheduler waits until the first one is finished |
Available CLI helpers
List all available tasks (dynamic and persisted):
flow task:listRun all due tasks (dynamic and persisted):
flow task:runDirectly run a single task:
flow task:runSingle --task [identifier]Enable a persisted task:
flow task:enable --task [identifier]Disable a persisted task:
flow task:disable --task [identifier]TODO
Feel free to open issue if you need a specific feature and better send a pull request. Here are some idea for future improvements:
- A Neos backend module to have an overview of tasks
- Asynchronous task handling or multi thread (pthread support)
