You can also limit the number of processes to run at a time. ``` $pool = new PriorityPool(); $pool->add(new Process('sleep 100'), [], 1); $pool->add(new Process('sleep 100'), [], 0.1); $pool->add(new Process('sleep 100'), [], 5); $pool->add(new Process('sleep 100'), [], 10); $pool->add(new CallbackRun( function () { return 'yarp'; }, [], 2 ); $pool->run(); // blocking that will run till it finishes ``` ### Recursive Pools [](#recursive-pools) You can add a Pool as a child to a parent pool. A Pool will act just like a standard run and hide the child runs. If the parent is a PriorityPool, it will control all the child runs so that priorities and the max simultaneous configuration options still apply. ``` $pool = new Pool(); $pool->add(new Process('sleep 100')); $pool2 = new Pool(); $pool2->add(new Process('sleep 100')); $pool->add($pool2); $pool->run(); // blocking that will run till it finishes ``` ### Display [](#display) You can output runs in a few different ways to the command line. These require the use of the package: [`graze/console-diff-renderer`](https://github.com/graze/console-diff-renderer). #### Table [](#table) Visual output of the parallel processes ``` $pool = new \Graze\ParallelProcess\PriorityPool(); for ($i = 0; $i < 5; $i++) { $time = $i + 5; $pool->add(new Process(sprintf('for i in `seq 1 %d` ; do date ; sleep 1 ; done', $time)), ['sleep' => $time]); } $output = new \Symfony\Component\Console\Output\ConsoleOutput(); $table = new \Graze\ParallelProcess\Display\Table($output, $pool); $table->run(); ``` [![asciicast](https://camo.githubusercontent.com/67b1742053ca1809ebdf0143a4504a94fa2d61ee62c899ae46a340009a8cacb1/68747470733a2f2f61736369696e656d612e6f72672f612f353572307266397a696e3439733735316a3361387a626477312e706e67)](https://asciinema.org/a/55r0rf9zin49s751j3a8zbdw1) #### Lines [](#lines) Write the output of each process to the screen ``` $pool = new \Graze\ParallelProcess\PriorityPool(); $pool->setMaxSimultaneous(3); for ($i = 0; $i < 5; $i++) { $time = $i + 5; $pool->add(new Process(sprintf('for i in `seq 1 %d` ; do date ; sleep 1 ; done', $time)), ['sleep' . $time]); } $output = new \Symfony\Component\Console\Output\ConsoleOutput(); $lines = new \Graze\ParallelProcess\Display\Lines($output, $pool); $lines->run(); ``` [![asciicast](https://camo.githubusercontent.com/939ea9851315ca9c7d32133a98ce46b573cc419a3efb94a30f51fed9a083448c/68747470733a2f2f61736369696e656d612e6f72672f612f5a7072314a684754786d736f44584246526a7352656b3477742e706e67)](https://asciinema.org/a/Zpr1JhGTxmsoDXBFRjsRek4wt) Testing ------- [](#testing) ``` $ make test ``` Contributing ------------ [](#contributing) Please see [CONTRIBUTING](CONTRIBUTING.md) for details.
