- sheet_ds_formulas(:Sheet, -Formulas) is det
- Formulas is a list of generalised formulas in Sheet
- sheet_formula_groups(:Sheet, -Groups, -Singles) is det
- ds_formulas(+Formulas:list, -DSFormulas:list) is det
- sheet_dependency_graph(:Sheet, -UGraph) is det
- Create a UGraph that represents the dependencies between cells.
Nodes in the cells are terms
cell(S,X,Y).
- cell_dependency_graph(:Sheet, +X, +Y, +Direction, -Graph) is det
- True when Graph is an Ugraph expressing the dependencies of
StartCell. Direction is one of
inputs, outputs or both.
- To be done
- - Implement
outputs and both. Probably need to
materialize the dependecies for that. We could do
that while loading the spreadsheet?
- generalize_formula(F0, F) is det
- generalize_formula(+S0, +X0, +Y0, +F0, -S, -X, -Y, -F) is det
- F is F0, after replacing coordinates by the variables X and Y or
constraints thereof. The idea is that F now unifies to other
formulas that have the same structure with the same relative
cell positions.
