Just be careful, that privateState thing looks like a Moose only Famix feature. It't not available in plain Pharo objects :) On Wed, May 9, 2018 at 2:09 AM, Alidra Abdelghani via Pharo-users < pharo-users@lists.pharo.org> wrote:

Adding instance variables to classes Hi Pavel,
Thank you for your answer. I actually didnât know about this mechanism. I think it is will do the job :) I have probably to rewrite some parts pf my code to access my variables through privateState. no?
Thanks again Abdelghani

I am working on a package named ClassNamesAnalyzer and I need to add code to third party classes in other packages (for instance the FAMIX-Core package). ?Extending? third party classes with methods is easy; I just need to categorise my methods under the *ClassNamesAnalyzer protocole so that loading my package will load them in the image. However, if I want to add instance variables to theses classes, they are not there when I load the package in a new image.
*So my question is* : is there a way to include instance variables addition to other packages in my package?
Currently not, you should use privateState
*Another question is* : is it good practice to add instance variables to classes in third party packages and is there a way to avoid it (because I am not very confortable with that idea)?
It is not, see FAMIXContainerEntity>>#definedAnnotationTypes how this issue is currently being solved using the privateState.
Cheers, -- Pavel
Thanks in advance, Abdelghani
