I have some questions/comments:

When preparing a document upon an Isabelle formalization (or to be more specific, let's say an AFP entry) its obvious to base the corresponding session on the available AFP sessions. To achieve this, I did:

  # create a directory 'dir'
  # change into that directory
  isabelle mkroot -d -n SessionName
  # now in the generated ROOT file I put
  session "SessionName" = "Name-of-AFP-session" +
    options [document = pdf, document_output = "generated"]
    theories Test
    files "document/root.tex"
  # to build a PDF, I have to run (at least I think so)
  isabelle build -D . -d '$AFP'

I believe for a user this is the common use-case. Thus, why not minimize the necessary typing by setting defaults appropriately? What seems inconvenient to me is that I have to put "-D ." and "-d '$AFP'" manually every time I want to build (or "-d ." and the full session name). I'd rather like that just 'isabelle build' achieves exactly this.

- How about making "-D ." the default (as long as a ROOT file exists in the current directory). Would this cause any problems? If so, at least "-d ." by default would be convenient. Plus the possibility to mark a session as default build target in a ROOT file (such that it does not have to be given explicitly on the command line). What do you think?

- Moreover, a persistent way (e.g., as part of the ROOT file) to set dependent directories would be nice, e.g.,

  session "SessionName" = "$AFP/Name-of-AFP-session" + ...

having the effect of "-d '$AFP'".

Maybe there is already a way to do what I want and I just didn't see it?

cheers
