-------------------------------
Summary: More consideration for option overriding
Key: CLI-301
URL: https://issues.apache.org/jira/browse/CLI-301
Project: Commons CLI
Issue Type: Wish
Components: CLI-1.x, Options definition, Parser
Affects Versions: 1.4
Environment: Any
Reporter: Balz Guenat
It is currently quite cumbersome to define options where later occurrences
override previous ones.
For one thing, a CommandLine.getLastOptionValue() would help. But this is easy
to implement yourself.
Another pain point are options with optional arguments. Say you have a boolean
argument foo that takes an optional argument "true" or "false". If no argument
is given, it should be set to true.
To get the correct value for foo, you first have to find the last occurrence of
the option, then check if it has a value and then return either the given value
or a default (which is likely different from the default value where the option
doesn't occur).
