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}
[EMAIL PROTECTED]:/> help --help
help
--
VAL Command name
-h (--help) Display this help message
{noformat}
Ideally this should be rendered as:
{noformat}
[EMAIL PROTECTED]:/> help --help
syntax: help [options] [COMMAND]
arguments:
COMMAND Command name
options:
-h (--help) Display this help message
{noformat}
--
