Hi!

You can request for a fully licensed IRIS on this page

If you want to try or use IRIS features with IRIS Community Edition:

Try IRIS online

Use IRIS Community from DockerHub on your laptop as is, or with different samples from Open Exchange. Check how to use IRIS Docker image on InterSystems Developers video channel.

or run Community on Express IRIS images on AWS, GCP or Azure.

HTH

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:
