How to define functionSignatures.json for a subpackage?

3 views (last 30 days)
I would like to use the function signatures mainly for autocompletion of the 'namevalue' argument options in the Command Window. My problem is that I tried to define the function signatures of a function that is in a subpackage and I get the message "Cannot diplay function hint. Cannot parse more than two levels of dot referencing". Heres an expamle of the structure of the package.
path/functionSignatures.json
path/+mypkg1
path/+mypkg1/funpkg1.m
path/+mypkg1/+mypkg2
path/+mypkg1/+mypkg2/funpkg2.m
How or where should I define the functionSignatures.json file to be able to have the functionality I seek?
UPDATE: The autocompletion works as intended for namevalue arguments, it's just the function hint that isn't displayed that I'd like to know how to fix.

Hi Oscar,
I couldnot find any mistake with your code. I think may be there is some issue in json file.
Can you check it using validateFunctionSignatureJSON.
Attached is copy of example that I tried.
Hope it Helps

Hi, what code are you refering to, I did not post any code.
Here's the output from validateFunctionSignatureJSON:
validateFunctionSignaturesJSON completed without producing any messages.
I tried the examaple you're providing and I still get the same error message "Cannot display function hint...". But your example made me realize that the autocompletion does work, also with my code. It's just the function hint visualization that isn't working. I would also like to have the function hint to see the 'required' and 'ordered' arguments.
Here's a screenshot of the message I get when trying your code, this is identical to the one I get with my code.

I have another question related to this. I this example the auto-complete is working fine, up 2 the point that I start defining inputs.
-->
I continued on your example; Only after I've entered my first input, the rest of the inputs are not suggested anymore. Does anyone recognize this problem?
In the example below I see that the auto-complete should continue to suggest the next input, but somehow I only get the suggestions before I define any inputs. So I don't get what I'm doing wrong.
