Ability to specify Java command-line arguments such as 'RELATIVE_INCLUDE'

[hannotify]

Hi! First of all: thank you for this amazing IntelliJ plugin. My team uses it currently to create C4 architecture diagrams using PlantUML.

Now I cloned the C4-PlantUML repository and want to use its files locally because of a company proxy. When creating a component diagram I include the local copy of C4_Component.puml, for example. But that file includes the C4_Container.puml from the internet by default. If I want to use a local copy, I have to set the RELATIVE_INCLUDE command-line argument. Is there a way to achieve this with the plugin?

I have noticed there is a settings field for PLANTUML_LIMIT_SIZE; we could perhaps generalize this and allow custom command-line arguments instead? I would be more than happy to contribute to that.

TL;DR: Can we specify Java command-line arguments such as RELATIVE_INCLUDE in the plugin? Or would you accept contributions to achieve this?

It can be done like this:

Perhaps a specialized variable table would be better.

I tried what @krasa said in the previous comment but unfortunately it doesn't work for the PLANTUML_SECURITY_PROFILE (https://plantuml.com/security). It tried it with and without the $.

%set_variable_value("PLANTUML_SECURITY_PROFILE", "UNSECURE")
%set_variable_value("$PLANTUML_SECURITY_PROFILE", "UNSECURE")

It think it is normal that this isn't working as it isn't a variable. Rather a security directive which shouldn't be specified as part of any diagram. Maybe a dedicated dropdown for the PLANTUML_SECURITY_PROFILE would be a better option in the long term. However it would be great to allow the specification of java system properties as it could be useful in the future.

Modifying IDE's VM options should work. It is initialized once per process/classloader. A dropbox could maybe be added.

Modifying the IDE's VM options sounds overkill. I'm not familiar how Idea's plugin system works but after a quick search I found this: https://github.com/esteinberg/plantuml4idea/blob/master/adapter/src/org/plantuml/idea/adapter/Utils.java#L93

Am I right to assume that

• The Utils.java needs an update to handle the dropdown and/or a arbitrary list of system properties.
• The settings page needs a dropdown and/or the list.

I couldn't find the test for that. Can you please point me to the right direction?

[krasa]

Yes, Utils.java could handle PLANTUML_SECURITY_PROFILE as well. Until then, IDE's VM options is the way to do it.

There is no test :-)
