Expr is an engine that can evaluate expressions. Expr is a fork from https://github.com/antonmedv/expr
We used the initial package to add custom formula in our package https://github.com/datasweet/datatable. We forked the initial project to fit our needs: operators and functions must process scalar or slices.
column + 1with column = [1,2,3,4,5] output = [2,3,4,5,6]
Also, we removed the map nodes (ie {"foo": "bar}), the struct evaluation, and the type checking before evaluation.
