CmdArgLib_CommandAction

This package contains three examples using the CommandAction macro provided by the Command Argument Libary.

Tip

If you want to experiment it is recomended that you use the follow cycle.

• Edit sources at ~/Temp/CmdArgLib_CommandAction/Sources
• Go to the "build" terminal tab at ~/Temp/CmdArgLib_CommandAction
• Rebuild: > swift build -c release
• Go to the "release" terminal tab at ~/Temp/CmdArgLib_CommandAction/.build/release
• Run the programs > ./ca...

Occasionally you might want to run rm -rf .build .swiftpm in the build tab. If you do, be sure to close the current release tab, and set up a new one after the build completes.
