I was just looking through the code and have a couple of minor comments:

  1. https://github.com/mlubin/AMPLMathProgInterface.jl/blob/master/src/AMPLMathProgInterface.jl#L40: no, as far as I know, the ASL doesn't supply functions to compute Jacobian-vector products. @vitaut will confirm though.
  2. https://github.com/mlubin/AMPLMathProgInterface.jl/blob/master/src/AMPLMathProgInterface.jl#L58: determining that the objective is linear is a matter of exposing nlo, etc., in aslinterface.c. I'll add that to the wish list. I don't think you can determine that the objective is quadratic without exposing the DAG and walking it à la Dr.AMPL.

It doesn't AFAIK
