🚀 Executing child Processes from Swift scripts and CLI tools

Running child processes in Swift is not hard with Process, but it can be a bit tedious and repetitive.

System makes this task extremely easy. If you are familiar with Ruby scripting (Rakefile, Fastlane, Danger, etc), you will feel like home.

💻 Automatically redirect output to stdout

import ProcessRunner

try system(command: "echo hello world") // prints "hello world" to stdout

✇ Capture process output

import ProcessRunner

let output = try system(command: "echo hello world", captureOutput: true).standardOutput
print(output) // prints "hello world"

✔️ Check if process terminated gracefully

import ProcessRunner

print(try system(command: "echo hello world").success) // prints "true"

|> Easily execute Shell commands with pipes and redirects

import ProcessRunner

try system(shell: "echo hello cat > cat && cat cat | awk '{print $2}'") // prints "cat" to stdout
