If the out expression of a computation is "too long", then Cadabra 1 deals with it in a particular manner. It would say that the output is suppressed within the notebook without giving an error. Presumably, in this case one can safely proceed to the next level of the computation. That's how I've been dealing with it so far.
However, Cadabra 2 gives out an error:
"Output cell too large (breqn dimension too large), output suppressed. See /tmp/cdbz76OR0.tex to debug this."
in a separate window with the title: "Generic TeX error". Moreover, when you go back to the notebook (upon clicking OK on the error-window), the progress wheel at the bottom continues to revolve.
It's not clear to me at this stage how to proceed further. How can I reliably go ahead and proceed to the next level of computation?
It seems to me that in some computations I can avoid such a long output only if I'm able to use "unwrap" before "distribute". However, this approach has a problem as I described in a separate question.
Therefore, at a case-specific level, my problem is the following: Being able to use "unwrap" is vital for my computation. This works only in V.2 which doesn't seem to be efficient in handling long output expressions.
