Async Process

Small library for making it easier to spawn processes in java with a modern api.

Usage

AysncProcess comes with a few static methods, to either create a builder that can be launched by calling start().

Prepare a command and then spawn it:

AsyncProcess.cmd("echo", "foo").start();

Or calling the run() method to directly spawn a command

AsyncProcess.run("echo", "foo");

The run method is overloaded to make it possible to directly spawn commands with stdin/out/err set, it is recommended to use the builder created by the cmd builder in order to get clearer code though.

Advanced usage

Here the cmd method is imported statically:

    cmd("echo", "foo")
        .in(supplier)
        .out(consumer)
        .err(consumer)
        .start();

In sets the stdin supplier, expected to be of type Supplier<String> it expected to block when it doesn't have data and the supplier will never be called again after supplying a null value.

Todo

• Give the user the possibility to specify environment through a hashmap
• Go through handling of the communication threads and verify the paths
• Better documentation
• Any other TODOs in the code.
