In particular, use this feature in many loops which feature a special treatment
for the first iteration, using a boolean variable (replacing iterator
manipulation). By the way, also use std::exchange() to simultaneously test the
value of this variable and update it.
And, symmetrically, when the “bytecode” option is requested by the user, always
create the .m static/dynamic files.
The “bytecode” option therefore no longer modifies the preprocessor output.
The vectors were previously stored as strings internally, which would not
necessarily contain the commas which are required in JSON (but not in
MATLAB/Octave). The fix consists in internally storing those options as
std::vector.
Closes: #96
Incidentally, in the JSON output, no longer assign a value to the “periods”
field if not passed by the user (previously the value -1 was output in the JSON
file).
The existing check would incorrectly fail if ramsey_constraints appeared before
ramsey_{model,policy}.
Also, the check would not terminate the processing in case of error.
Closes: #91
For symbol lists (such as those given to “var” or “stoch_simul”), return a
semantic value at the Bison level, rather than building the list through a
temporary object in ParsingDriver. This allows various simplifications, and
leads to a more functional code.
By the way, homogeneize the naming of the various flavours of symbol lists in
the Bison file (with TeX names, partitioning, or with a wildcard).
The existing check (in AbstractEstimatedParamsStatement::commonCheckPass()) was
only working inside a given estimated_params block, but not across blocks.
This option provides the same behaviour as before the change in
60ef6bbdbd.
It is typically useful when doing several estimations in the same .mod file.
Incidentally, the auxiliary endogenous variable representing Z₁ and created for
PAC MCE models no longer necessarily appear as the first auxiliary variable (so
this is effectively a revert of 64f55e4a5e).
— forbid leads and lags
— forbid expectation operators
This is implemented by moving the occbin_constraints expression to a separate
DataTree. As a side-effect, this removes the spurious non-linearity warning in
a stochastic context (because we were introducing inequalities and abs()
operators in the main DynamicModel tree).
In particular, this implies that steady state values of endogenous in the
“occbin_constraints” block must now be specified using the STEADY_STATE()
operator (and not with a “_ss” suffix).
Moreover:
– make various simplifications to the fields generated under M_
– in the driver file, replace the call to occbin.initialize() by a few explicit operations
Ref. #68
Consequently drop “occbin” option to “model”.
Incidentally, allow more values in equation tag names (previously some keywords
such as “alpha” were disallowed).
Ref. #68
Writes the number of temporary terms of the planner objective function derivatives objective_tmp_nbr in the driver.m file.
Useful for the k-order approximations of welfare.
For the time being, the preprocessor will refuse that this option be used with
any command other than estimation.
By the way, remove occbin_likelihood and occbin_smoother options to estimation.
Ref. dynare#569
Writes the number of non-zero derivatives of the planner objective function NNZDerivatives_objective in the driver.m file. Useful for the k-order approximations of welfare.
