Functor for parsing and building spreadsheets.
Defines a spreadsheet functor and
RowSpec module type.
When given a
RowSpec, the functor produces a module that will represent a
spreadsheet backed by a set.
The programmer must provide a
RowSpec module, which is essentially:
- An OCaml type to describe spreadsheet rows.
- Coercions from the row type to/from
string listtitle describing each column of the spreadsheet.
