override def stopAtFirstUnrecognized: Boolean

Whether to stop parsing at the first unrecognized argument.

Whether to stop parsing at the first unrecognized argument.

That is, stop parsing at the first non option (not starting with "-"), or the first unrecognized option. The unparsed arguments are put in the args argument of run.

def expandArgs(args: List[String]): List[String]

Arguments are expanded then parsed. By default, argument expansion is the identity function. Overriding this method allows plugging in an arbitrary argument expansion logic.

Arguments are expanded then parsed. By default, argument expansion is the identity function. Overriding this method allows plugging in an arbitrary argument expansion logic.

One such expansion logic involves replacing each argument of the form '@ ' with the contents of that file where each line in the file becomes a distinct argument. To enable this behavior, override this method as shown below.

import caseapp.core.parser.PlatformArgsExpander
