Hello,

 

     I am trying to extend nonposArgs to include more checks and I am having a hard time.    I have gotten basic checks working, but I am not able to get some of the more complicated checks working.

 

    The tutorial shows that the syntax for extending nonposArgs is:

 

 someobject|someclass proc|instproc methodName {?optional arguments? argName args} {
  ...
}
 

I have not been able to get the ?optional arguments? to work.

 

Example:

 

I am trying to get some checks done that will check for specific values of the Arg.   I would like to be able to pass those values into the check.

 

xotcl::nonposArgs proc RANGE {allowedRange argName args} {

.....code to verify the range

}

 

The syntax to use this would be similar to:

 

Class Foo

Foo instproc setMtu {{-mtu:RANGE 54-65535 "1500"}} {} {

....

}

 

This is similar to what Giovannni Cristelli asked in the post titled XOTcl extending nonPosArgs class from November 2004.

 

Is there any way to do this currently?   I am trying to replace a bloated package that is currently being used which has many of these checks available.   I have tried many combinations of syntax to get this to work and have not been able to figure it out.

 

Thanks,

 

Shawn
