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
– also use vectorized versions for .+ and .-
– add a space before vectorized operators to avoid syntactical ambiguity
This commits complements bfdcc546ec.
When an endogenous is declared with “var(log)”, say “y”:
– creates an auxiliary named “LOG_y”
– replaces “y(±l)” everywhere by “exp(LOG_y(±l))”
– adds a new auxiliary equation “y=exp(LOG_y)”
– adds a new definition “LOG_y=log(y)” in set_auxiliary_variables.m and
dynamic_set_auxiliary_series.m files
This option also works in conjunction with “deflator=…”, such as “var(log,
deflator=…)” (the “log” must appear befor “deflator”). There are no provisions
for combining “log” with “log_deflator”, because that would not make much sense
from an economic point of view (amounts to taking the log two times).

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).
This is a more natural semantics.
Incidentally, this fixes a bug in the variable mapping (M_.mapping) where some
endogenous, appearing in a log() in a VAR or TCM, would not be mentioned (e.g.
in the var-expectations/7/example1.mod test, and many others).
By the way:
– Fix and improve the explanation of the purpose of the orig_symb_id and
orig_lead_lag fields for auxvars
– Factorize the code that prints those fields in MATLAB and JSON output
The logic was flawed in several ways. In particular, the test files
pac/trend-component-{3,10,11}/example1.mod would return A0 and A0star matrices
where the (2,2) element was incorrectly zero.
The case of a diff aux var corresponding to a complex expression was not
correctly handled, and could lead to a value -1 being returned by these
methods.
By default, the preprocessor substitutes logs and diffs by auxiliary variables
only in equations of auxiliary models (VAR, PAC). Hence they are not
substituted in the equation defining the target, since it is outside the
auxiliary model.
The fix consists in doing the substitution in that equation as well, when we
parse the linear combination within that equation.
