Hi,
Just for your information, I have started a Dynare package for Julia. Note that this is not a binding to the MATLAB/Octave code, but rather a (very preliminary and incomplete) rewrite from scratch.
https://github.com/DynareTeam/Dynare.jl
For the moment, this is only thought as a prototype for exploratory purposes. It only does steady state computation and first order decision rules.
One interesting point is that it is 100% pure Julia code: I could write the equivalent of the preprocessor (symbolic derivatives) and of mjdgges (MEX for QZ decomposition) entirely in Julia code, without the need for C/C++. Also note that the code is very small (less than 800 lines, including newlines).
