Hi @Anton Umnikov ! Thanks for raising this topic. 

The question of the most acceptable folder structure widely discussed already on community. 

As for Atelier, - why do you care where it puts the code? I believe you can maintain your code in a folder structure you like and let Atelier compile it and bring back in a place it took it, right?

Guys, thanks for a lot of options! It looks like it is a relevant question ;)

Personally I feel that 3 parameters for a method are OK, but 4 is too much. But how much is for an average developer? Is there is a consensus about it?

If I know, that method will accept a lot of settings and not all of them are mandatory, I like the .args approach, which @Robert.Cemper mentioned and which, e.g. is introduced in e.g. in Database, Namespace and Web App management functions. E.g.:

set props("NameSpace")="Namespace"

set props("Enabled")=1

set props("DeepSeeEnabled")=1

Do ##class(Security.Applications).Create("AppName", .props)

It's readable and you don't count commas.

Also I'm curious if we can setup and pass a JSON that easily too? Would be great.

Thanks, Ed!

I placed iscpython.so file into the repo floder and this helped - docker-compose build worked smoothly and container started.

So I managed to build this with  IRIS Community Edition, though you need to go directly to PYTHON namespace to make it work - class mapping is not available on IRIS CE unfortunately.

Anyway, python in container is callable from IRIS:

Namespace: 
You're in namespace USER
Default directory is /usr/irissys/mgr/user/
USER>zn "PYTHON"

PYTHON>set sc = ##class(isc.py.Callout).Setup()

PYTHON>set sc = ##class(isc.py.Main).SimpleString("x='Hello from Python'", "x", , .x)

PYTHON>write x
Hello from Python
PYTHON>set sc = ##class(isc.py.Callout).Finalize()

PYTHON>set sc = ##class(isc.py.Callout).Unload()

PYTHON>

Tried to do a docker-compose locally and got failed. Here is the part of trace:
