summary | The provided content explains how to create a launchd configuration file (plist) in XML format using examples of running an Ergo IRC server with AppleScript command-line arguments as well as starting up the Luminus Node.js application at boot time.
A plist is essentially a property list that defines what commands or scripts should be run by macOS's System Preferences app. It includes elements such as 'Label', which serves to uniquely identify services, and specifies where they can start (ProgramArguments), whether it starts upon loading the preferences ('RunAtLoad'), if it's set up for continuous operation even after a crash ('KeepAlive'). Other details include working directories from where files are accessed by programs during startup or when they're running. In addition, there is provision to specify paths of standard output and error streams (StandardOutPath/ StandardErrorPath) as well as environment variables that can be used.
Moreover, the plist also lets you set a 'StartInterval' for periodic execution in seconds; it could alternatively have start calendar intervals if started at certain times. This allows an application or service to run periodically throughout day and night even when no user is active on their computer.
The examples show how this can be accomplished using different platforms - the Ergo IRC server running with AppleScript command-line arguments, while Luminus Node.js app starting up through a similar configuration file.
The author mentions that he bypassed Homebrew services because they were found to not fulfill his specific needs and due their opaque nature (not being able to see what's happening inside them) making it difficult for troubleshooting.
The plist files can be created manually or generated using tools such as PlistBuddy, a scriptable tool from Appleās command line that lets you manipulate property list data in .plist binary XML format.
In conclusion, this content is an explanation of how the launchd service configuration mechanism works on macOS systems for starting up applications and services at boot time with custom parameters. |
