Howto implement TCL shell commands:
All parameters passed to command should be possible to set as None and test it afterwards.
This is because we need to see error caused in tcl,
if None value as default parameter is not allowed TCL will return empty error.
Use:
def mycommand(name=None,...):
Test it like this:
if name is None:
self.raise_tcl_error('Argument name is missing.')
When error ocurre, always use raise_tcl_error, never return "sometext" on error,
otherwise we will miss it and processing will silently continue.
Method raise_tcl_error pass error into TCL interpreter, then raise python exception,
which is catched in exec_command and displayed in TCL shell console with red background.
Error in console is displayed with TCL trace.
This behavior works only within main thread,
errors with promissed tasks can be catched and detected only with log.
TODO: this problem have to be addressed somehow, maybe rewrite promissing to be blocking somehow for TCL shell.
Kamil's comment: I will rewrite existing TCL commands from time to time to follow this rules.
