As a consequence, and as a temporary measure, always output the
non-block-decomposed legacy representation.
Also drop the block kalman filter output, and drop now useless variables in
M_.block_structure.
The new representation is only supported for MATLAB/Octave, C and Julia output
for the time being. Bytecode and JSON are unsupported.
This commit adds new fields in M_.
This is a preliminary step for dynare#1859.
– DataTree::packageDir() now takes a std::string_view, returns a
std::filesystem::path, and no longer creates that directory
– DataTree::writeToFileIfModified() now takes a std::filesystem::path as
argument
– Do not call DataTree::writeToFileIfModified() for generating MATLAB/Octave
files, since it does not work (the directory inside which the file is written
has been deleted by the preprocessor just before)
– Consistently use DataTree::packageDir() everywhere (for compatibility with
planner_objective)
This is unsafe since the find() method can return a past-the-end iterator,
which should be tested for.
Replace most instances by calls to the std::map::at() method (which throws if
the key is unknown), and which is incidentally more readable.
When computing the derivatives or block decomposition of the planner objective,
the epilogue or the original Ramsey model, the preprocessor would talk about
dynamic/static model, which was confusing. It now uses the right terminology.
If block decomposition fails, error out if “block” option was passed, but not
otherwise.
This commit does not modify the generated files.
This is a preliminary step for dynare#1859.
Compute temporary terms for derivatives of “evaluate” mode, even though those
derivatives are not computed. This is because the temporary terms may be useful
for subsequent blocks.
By the way, add an explanatory comment for the equivalent code in dynamic file.
– factorize common code between the static and the dynamic version
– reorganise language-specific code into dedicated functions
– use a function template in the main helper to do some computations
at compile-time (using constexpr features)
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.
We follow the advice given by Josuttis in his book about move semantics.
Deleting those member fuctions can be a bug if we want to allow copy semantics,
because overload resolution will no longer fallback to the copy
constructor/assignment operator when given an rvalue.
In particular, this explain why it was not possible to delete the move
assignment operator of the StaticModel class.
In particular, in dynamic models, temporary terms are now computed for
derivatives w.r.t. exogenous, and also w.r.t. endogenous variables that do not
belong to the block.
— use a std::map for storing block derivatives
— remove redundant ModelTree::first_chain_rule_derivatives structure
— remove unused codepaths in StaticModel
— DynamicModel: simplify code that determines the type of derivatives in a
block. We now use a slightly different categorization.
— by the way, fix the max lead/lag information for blocks that are obtained via
merging. A workaround was previously implemented in
DynamicModel::get_Derivative(), but it is no longer needed with this fix.
