An extensible, asyncio interface to subprocesses, plus a set of wrappers around common system tools that works well with yaclipy

Tools

• curl
• docker
• ffmpeg
• firebase
• gcloud
• git
• gpg
• graphviz
• grep
• kubectl
• md5
• nginx
• openssl
• shasum

The set of tools can easily be extended by subclassing SysTool

ProcTask

This creates an asynchronous connection to a sub-process. It is based upon loop.subprocess_exec().

await ProcTask('diff', 'README.md', 'README.md') 0

For more complicated interactions, plugins are used.

await ProcTask.using(Lines(1))('ls', '-al') [...]

The Lines plugin captured stdout (1) and return a list of lines. If no plugins want to return a value then the default behavior is to return the returncode as seen in the above example. If multiple plugins want to return a value then they are returned as a tuple:

await ProcTask.using(Lines, Lines(2))('ls', '-al') ([...], [...])

The first value of the tuple contains the lines from stdout AND stderr, whereas the second list only contains stderr lines.

Echo

The Echo plugin prints to the print_ext Printer(). By setting the context you can create nice, grouped command output.

Lines

Capture the output and return a list of strings

OneLine

Capture the output but only return one of the lines

Input

Send data to stdin of the process

Log

Capture the output and send it to a file (or other io.Stream)

Watch

Ask for the output to be captured so that you can use it asynchronously.

SysTool

SysTool build upon ProcTask by integrating it with yaclipy and adding more user-facing features, such as:

• configurable command location (no more environment variables)
• Tool availability and version check.
• Helpful info about how to install missing tools.
