~ValueT

Classes

class pyTooling.CLIAbstraction.Argument.CommandLineArgument[source]

Base-class for all Argument classes.

An argument instance can be converted via AsArgument to a single string value or a sequence of string values (tuple) usable e.g. with subprocess.Popen. Each argument class implements at least one pattern parameter to specify how argument are formatted.

There are multiple derived formats supporting:

commands
→ Command
simple names (flags)
→ Flag, BooleanFlag
simple values (vlaued flags)
→ StringArgument, PathArgument
names and values
→ ValuedFlag, OptionalValuedFlag
key-value pairs
→ NamedKeyValuePairsArgument
