Start diary earlier to include input arguments and Dynare version

Currently, the diary only starts after the version and the input arguments have been printed. That way, important information is missing when calling a mod-file with command-line switches.

You mean you want the preprocessor to include its own output inside the log file, before the diary function is actually called?

Yes, I want it to consistently contain the output. Now I have

Starting preprocessing of the model file ...
WARNING: A parameter was used with a lead or a lag in the model block
Substitution of endo leads >= 2: added 2 auxiliary variables and equations.
Substitution of endo lags >= 2: added 2 auxiliary variables and equations.
Found 48 equation(s).
Evaluating expressions...done
Computing static model derivatives (order 1).
Computing dynamic model derivatives (order 3).

instead of the full

Using 64-bit preprocessor
Starting Dynare (version 4.6.2).
Calling Dynare with arguments: -Dsticky_prices=1

Actually the lines that you want to have included are not generated by the preprocessor, but by dynare.m. That means that the call to diary has to be moved there.

moved from preprocessor#56 (moved)

Could we then also enclose

evalin('base',[fname '.driver']) ;

in try-catch? I.e.

try
    evalin('base',[fname '.driver']) ;
catch EM
    diary off
    rethrow(ME)
end

In the current implementation if the mod-file crashes the diary is locked and cannot be deleted.
