I have created a simple gateway event script for testing.

```auto
def test:
      a =1
      b=2
      c = a+b
      print c

test()

```

And i have named this script as **Test**  
After saving the script, i have waited for this to execute automatically but didnt work.

if i run the same script in script console, it is working… I believe there is nothing wrong with this test script.

I just wanna run this Test script automatically, Anyone pls tell me how to do that?

When you create a gateway event script you have to choose what event is to trigger it. Your options are:

- Startup
- Update
- Shutdown
- Timer
- Tag Change
- Message
- Scheduled

Which did you choose and what was the trigger?

That’s a library script, not an event script. Library scripts don’t run unless an event calls a function within them. One of the events @Transistor listed.

Edit: Also note that when you have an event that calls `Test.test()`, the first time will yield **two** calls to `test()`, since you include a call at the top level of the library script. The top level runs once, to completion, the first time any member of it is accessed. (Like an auto-import.)

Another thing to note here is that `print 'hi'` in the gateway context - you will never see this.

You need to use a logger to log your messages to the gateway.

```auto
def test():
    logger = system.util.getLogger("My Logger")
    a=1
    b=2
    c = a + b
    logger.info("Value of c is %i"%(c))

```

is how you would be able to see results in your gateway logs.

You need to be more precise in your writing. Your question title says "event script". I now suspect that you mean you have written it in the Project Library.

You can run a Project Library script from a button.

- Right-click the button.
- Select _Configure Events ..._.
- Select _onActionPerformed_, hit + and select _Script_.
- Add the path and name of script.

Thanks,  
I was doing it in multiple ways, forgot to rename it.

If anyone else forgot like me - syntax of the path and name of the script is not as the project browser "copy path" feature gives - need to change slashes for dots.  
So not `Folder/Subfolder/Library_Script.method(args)` but `Folder.Subfolder.Library_Script.method(args)`

Edit: Project browser tree copy path. Didn't know there was a similar tool in the script editor!

In new-ish versions of Ignition, the auto complete (Ctrl+space) will provide you paths to your project library functions.

Thanks, yeah. Even without ctrl+space, 8.1 does propose completions if you start typing but if you paste an invalid path after copying one then it it does not.

What ? Where are you copying it from ?  
Mine gives the proper path:

> `lib.dict.sanitize_keys(dic, sfunc=make_key, recursive=True)`

Probably from the project browser menu. I can see how that would be confusing.

Right, didn't even notice you could get a path from there. Not sure what it would be useful for though ?

Mostly useful for Vision windows, but probably a generic action added to an abstract tree node class, so everything gets it.
