Hi,

with Sirius, how can I specify Load/Save options for semantic resources
at runtime? For example say there's a user preference to pretty print
xml or not.

Thanks,
Felix

For loading, maybe something like this (completely untested):

rs = session.getTransactionalEditingDomain().getResourceSet();
rs.getLoadOptions().put(KEY, VALUE);
session.addSemanticResource(uri, pm);

The actual loading is performed using ResourceSet#getResource(uri,
true), which should honor the default load options set on the resource
set. You may want to revert your customizations afterwards if they can
have side-effects on other resources.

For saving, simply pass the options in the map argument of
Session.save(Map<?,?>, IProgressMonitor).

I see.

But won't this apply the options to all resources (semantic and
sirius/diagrams?)

Yes. If you need further control, you can provide your own
implementation of org.eclipse.sirius.business.api.session.SavingPolicy,
and configure the session to use it using Session.setSavingPolicy().

When your policy is called, it gets the options which were passed to
Session.save(), but you can then interpret them as you want, or set
specific ones for some of the resources.
