- abstract def get(command: String): Option[parser.Parser[T]]
Check if this caseapp.core.commandparser.CommandParser accepts a command, and return its caseapp.core.parser.Parser if it does.
Check if this caseapp.core.commandparser.CommandParser accepts a command, and return its caseapp.core.parser.Parser if it does.
- returns
in case of success,

Parse arguments.
Parse arguments.
Like
parse, but keeps the non option arguments in a caseapp.core.RemainingArgs.- returns
in case of error, an caseapp.core.Error, wrapped in scala.Left; in case of success, a
D, the non option arguments, wrapped in a scala.Right, along with the result of parsing the specified command if any.

beforeCommandParseras aD.- returns
in case of error, an caseapp.core.Error, wrapped in scala.Left; in case of success, a
D, the non option arguments, wrapped in a scala.Right, along with the result of parsing the specified command if any.
