Hi all I have ported over one of our applications from using itcl to using xotcl. I have a lot of code that already uses the itcl stuff, so the port must be backwards compatible. I have the following issue. Can anyone give me an idea how I can get around it? A script that shows my issue is as follows:
#!/usr/bin/tclsh package req XOTcl namespace import ::xotcl::*
::xotcl::Class Connect -parameter { {telnet} {ssh} {ip} } Connect instproc init {node args} { [self] instvar telnet [self] instvar ip }
Connect dev node -ip "127.0.0.1" -telnet
The above does not work, as it seems that the telnet arg must not be NULL, however, I need this to be NULL, as it is just a flag.
If I pass in: Connect dev node -ip "127.0.0.1" -telnet ³²
This works, however, this is not backwards compatible with how things were with itcl, and I have too many users/scripts to change how this is done. There are potentially 2 ways around this, however, I am unable to find information on if either of them are possible: 1. Allow the passing in of a NULL argument 2. Prevent the constructor parsing args so that I can parse my own
I would appreciate any assistance
Cheers Colin
