Subject [jira] Created: (CLI-160) Partial matching for long options
Date Fri, 25 Jul 2008 09:19:31 GMT
Partial matching for long options
---------------------------------

                 Key: CLI-160
                 URL: https://issues.apache.org/jira/browse/CLI-160
             Project: Commons CLI
          Issue Type: Improvement
          Components: Parser
    Affects Versions: 1.0
            Reporter: Emmanuel Bourg
             Fix For: 1.3


Partial matching is a common feature among command line processing tools. It allows to use
shorter option names as long as the abbreviation is not ambiguous.

For example on Debian 

{noformat}ls --he{noformat} 

is equivalent to 

{noformat}ls --help{noformat}

but 

{noformat}ls --h{noformat} 

returns the error "option `--h' is ambiguous", because 'h' is also the prefix of the --hide
option.
