Hi I'm trying to extend Pillar to get new $publications:...$ structure and it looks like Pillar is getting more and more complex. And the comments do not really help because they are short and written for someone already understanding it. :( To try to understand I tried to ! Youpi ${cite:ref=Duca18rmod}$ !! Others but I get {"content":"!Youpi\n\n\n\n!!Others"} ./pillar export --to=pillar Example.pillar May be I cannot export to pillar a citation. I have no idea. I tried to add PRPillarWriter >> visitCitationAnnotation: aCitation "We invoke visitAnnotation: to make sure that the rest of the document is visited." self halt. super visitCitationAnnotation: aCitation Did not stop! So I put an halt into PRVisitor >> visitCitationAnnotation: aCitationAnnotation self halt. self createNewCitationWith: aCitationAnnotation. self replace: (OrderedCollection with: tmpCitation) . super visitCitationAnnotation: aCitationAnnotation and it stopped. I tried to understand who is calling PRCitationTransformer No luck. I'm sure that there is a magic registration mechanism but I failed to find it. Looking at tests (BTW Tests are not documentation or class comments, there are tests). It looks like I need a configuration. (self actualClass executeOn: (PRCompilationContext withDocument: anInput withConfiguration: aConfig)) input And then I fall on executeOn: implementors..... LLPhase and PRNodeTransformer. and I have no idea how a Phase relates to a visitor. To bad, after all the efforts on Pillar it looks like getting too complex. So do not think that we can decently ask students to work on improving Pillar anymore because they will just get lost and disgusted from Pharo. :( Sad news isn't. I hope that I will not have to switch back to LaTeX or markdown (shit). Stef
