From a script, can I tell what scope it's running from? e.g. Gateway, Perspective, Vision, Designer, etc. I want to display an error popup, but the call is different for different scopes

This post came up in a lot in my searches and had to make adjustments to it to differentiate between whether a script was being run on the Gateway vs a Perspective Session Scope, IE whether Perspective session properties exist. Here is a quick change to the above method that solved it for me. from…

[image] Best methods for checking script scope Ignition Try this: def getScope(): """ Returns: scope (int): 0=Gateway, 1=Client, 2=Designer """ try: if system.util.getSystemFlags() & system.util.CLIENT_FLAG: location = 1 elif system.util.getSystemFla…

That's very useful! Hmm. I'll have to see if I can get it to return if it's in Perspective

Testing in perspective returns a gateway scope. from com.inductiveautomation.ignition.common.model import ApplicationScope scope = ApplicationScope.getGlobalScope() if scope == ApplicationScope.GATEWAY: ... if scope == ApplicationScope.CLIENT: ... if scope == ApplicationScope.DESIGNER: ... if s…

What events/context would trigger .ALL or .NONE?

None. You'll only ever get one of the three C/D/G values as the current scope for a script. The other values are used in other areas, but will never be returned as the current scope.

I recommend using hasattr() to probe the available functions in system.* to determine what is possible, preferably done at the top level of a script module with results placed into top-level booleans.

This is what we do to determine scope in a script from com.inductiveautomation.ignition.common.model import ApplicationScope def getScope(): scope = ApplicationScope.getGlobalScope() if ApplicationScope.isClient(scope): return "c" if ApplicationScope.isDesigner(scope): return "d" if Appl…

You can use something like hasattr(system, 'perspective') instead of trying to call a function. I think that's what @pturmel suggested.

Nah it doesn't work, perspective exists in global scope as well

Then the accepted solution is probably wrong too. I'd expect 'perspective' in dir(system) to return the same thing as hasattr()

Can I tell what scope a script is running from?

This is 2019 so whilst perspective was out then (April 2019 = 8.0.0) it doesn't mention that scope and may need tweaked for it
