Usage

Tasks implement the Multitron\Execution\Task interface. Here's a minimal example task:

You can register tasks in a command that extends Multitron\Console\AbstractMultitronCommand:

Register the command in your Symfony Console application and run it. Multitron will execute the tasks respecting dependencies and concurrency.

You can control how many tasks run at once via the -c/--concurrency option:

The library will spawn up to eight worker processes and keep them busy until all tasks finish.

To limit which tasks run, pass a pattern as the first argument. Wildcards work the same as in fnmatch() and you may use % in place of * for convenience:

You can also tune how often progress updates are rendered using the -u/--update-interval option (in seconds):

You may also constrain memory usage with the -m/--memory-limit option:

You can disable colors with --no-colors and switch off interactive table rendering using --interactive=no. The default --interactive=detect automatically falls back to plain output when run in CI.

Central Cache

Within a task you receive a TaskCommunicator instance that provides simple methods to read and write data shared between tasks:

Reporting Progress

Tasks can update progress counters that Multitron displays while running. Use the ProgressClient provided by the communicator:

You may also call addOccurrence() or addWarning() to report additional metrics or warnings.

Partitioned Tasks

When a workload can be split into chunks, partitioned tasks run those chunks in parallel. Define a task extending PartitionedTask and specify the number of partitions in the tree:

Accessing CLI Options

Options passed on the command line are forwarded to each task. Retrieve them via TaskCommunicator:

Call getOptions() to receive the entire array of options if needed.

Custom Progress Output

Multitron renders progress using a ProgressOutputFactory. Replace the default table display or combine outputs with ChainProgressOutputFactory:

Implement the factory to send progress anywhere you like.
