[REBOL] Re: Spreadsheet

From: brett:codeconscious at: 4-Mar-2001 11:24

The thought occurred to me. I actually did come across a situation where we wanted to provide spreadsheet functionality but in a very constrained manner. The reason being that the users were already using spreadsheets and were very nervous about causing errors. So they wanted a custom program instead, but they needed flexibility in how to define a calculation. We never did that app, because we were going to get a "better bang for buck" by doing other things first. Anyways my thoughts about doing this with Rebol: 1) Need to build a grid based entry interface style. Once done, very useful for other Rebol applications. 2) Need to code a graph sorting algorithm that gets as input the dependencies between cell calculations. 3) Need to provide all the little user-interface niceties that people expect from spreadsheet applications. 4) Aim to keep as much power of Rebol as possible accessible to user entered parts of the spreadsheet. I think (1) is the most reusable for other applications. (2) is an interesting problem to solve. (3) may actually be the most amount of work in the project - users expect a lot! but (4) is a good justification for a Rebol powered spreadsheet - Rebol programming can be made visual... Brett.
