Subject [jira] Created: (GSHELL-66) Auto-generate cli syntax/usage string when displaying --help
Date Wed, 14 Nov 2007 04:01:43 GMT
Auto-generate cli syntax/usage string when displaying --help
------------------------------------------------------------

                 Key: GSHELL-66
                 URL: https://issues.apache.org/jira/browse/GSHELL-66
             Project: GShell
          Issue Type: Improvement
      Security Level: public (Regular issues)
          Components: Support - CLP
    Affects Versions: 1.0-alpha-1
            Reporter: Jason Dillon
            Priority: Minor
             Fix For: 1.0-alpha-1


When generating a commands --help, the syntax/usage should be auto-generated.

For example take the {{help}} command's {{--help}}:

{noformat}
jason@Bliss.local:/> help --help
help
 -- 

  VAL            Command name
  -h (--help)    Display this help message
{noformat}

Ideally this should be rendered as:

{noformat}
jason@Bliss.local:/> help --help
syntax: help [options] [COMMAND]

arguments:
  COMMAND    Command name

options:
  -h (--help)       Display this help message
{noformat}
