Is it a matter of writing a comprehensive stats library?

Mesh can do this, somewhat - exceptions in table columns stick out like a sore thumb in the sheet source. http://mesh-spreadsheet.com

Mesh Spreadsheet is explicitly designed to make it easier to view and write decision tables with a projectional editor, while keeping the code as text for storage, version control, etc. https://twitter.com/meshspreadsheet&#x

I agree with most of this article, except that - for me - grouping by table columns is a more intuitive and flexible way to control subset application than 'rank'. k9 is in development, but blending k7 and k9 we'd get somethi

> you can name columns and use the name in formulas You can do that in Excel too: whether it's the whole column of a sheet, or a column of a table - syntax for latter is `someTable[someColumnName]`. Mesh will have the latter, albeit

Thanks! I have been considering this! It might impact the 'flow' of modelling eg using automatic cell names like 'A1'. And it might complicate storing the sheet as text (might need to store more complex layout info than

Yes, that's it.

When you say 'has the functionality of a spreadsheet but looks nothing like current spreadsheets', what do you mean? I am working on Mesh Spreadsheet. It gives you a spreadsheet UI that writes code as text. It will likely use k9 a

Yep. JavaScript can also work as a formula language (per the Mesh JS prototype), but APL family languages such as k are much more ergonomic - and 'punchy' - in a spreadsheet context.

It's probably like k's find (`?`), which gets the indices of the found elements, or else the length of the list (or null, depending on the dialect) if not found: "abc"?"caz" 2 0 3

Correction: I think the above can be a bit faster and shorter if we skip the dict, and just index into the keys. Compare: \t:100000 `freq@!s#>(s/!s*#v)!,/v%\.5+!s 941 \t:100000 `freq(s/!s*#v)s#>,/v%

Yes. When each function is a single character [1], juxtaposition is enough to show the calling order - eliminating the need for brackets in many cases, and reducing syntactic noise. [1] There's a handful of two-character primitives, as

Kind of - in Excel everything just has a location reference, even if you name it. So that means you can get collision errors if a dynamic array expands into another cell.

Thanks! And hopefully the README helps too: https://github.com/chrispsn/mesh/blob/master/README.md
