dentaku VS hyperformula

i'm super confused by "which gems you can't live without". is this my personal debugging collection of pry-rails, bullet and other things? i mean, whatever is required and does the job i guess. i absolutely love Dentaku gem and build awesome stuff with it in 2 different companies where it absolutely contributed to their product in huge ways (https://github.com/rubysolo/dentaku) . i also love Victor (https://github.com/DannyBen/victor) where i draw epic custom charts which are used in reports that been generated for billion dollar real estate funds.

A naive implementation - there's just one custom error and most of the API relies on built-in errors like RuntimeError and ArgumentError. Needless to say, this is a poor showing, problems will be hard to debug.

You can try this gem : https://github.com/rubysolo/dentaku

I haven't looked at Keisan, but I'd also recommend Dentaku for the same purpose.

My initial thoughts were how does a spreadsheet do it? but it's a different kind of beast.

In search of a parser toolkit I had come across this https://github.com/handsontable/hyperformula which uses chevrotain to parse spreadsheet formulas and decided to use chevrotain for the parsing.

There was a time when we used Excel Services in SharePoint to meet some of our business user needs. I wouldn’t use Excel again, but back then it seemed to be a good trade-off between time-to-market and usability (meaning performance for most of the time).

Anyhow, we use https://github.com/handsontable/hyperformula to run calculations in our other components these days.

My project only depends on the hyperformula package (https://github.com/handsontable/hyperformula) and it also causes the following error when building the image:
