In practice, for the time being, we limit ourselves to C++20 features available
in GCC 10 and clang 12 (the latter because of the Julia infrastructure).
– Indicate whether we are trying to normalize the static or dynamic model
– If failed to normalize the static model, suggest to use the “no_static”
option
– Remove a superfluous error message
The support for empty files at the macro-processor level, as implemented in
1291320053, was relying on
basic_streambuf::in_avail(), which does not seem to behave consistently across
platforms, and which may not be the right tool for the job.
Rather use the Bison grammar to support empty files.
Closes: #93
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

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.
