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 async-symfony-process
Description
Existing libraries work with an early generated pool of processes, this is poorly suited if there are a many processes and is generally not suitable if after the execution of the process it may be necessary to execute an additional one. This library to solve this problem.
This library works on the basis of the symfony/process
Install
Use
Basic
In the simplest case, you only need to specify a function that will generate new processes. If the function returns zero instead of a process, then execution will end after all current processes have finished executing.
Callback
If you need the result of a process, then you need to set a callback function that will be called after the completion of the process.
Output listener
If the process is interactive, or you need to somehow react to the errors that the process generates, then you need to set the output listener. It will receive an instance of the current process, output type (Process :: ERR or Process :: OUT) and data generated by the process.
While listener
To perform any actions at each iteration of the process execution loop, you must set a loop listener.
Endless execution loop
In order for the process execution cycle not to stop when the process factory returns zero, it is necessary to inform this when configuring the pool. You can react and replenish the list of processes in any of the called functions, for example, in the whileListener. If you need to halt infinite execution, then you need to specify this to the pool.
