Spreads

An always terminating, statically typed spreadsheet!

Motivation

Have you ever felt that your spreadsheet was holding you back? Wondered if there was a better alternative? Tired of thinking about what really is the last argument of COUNTIF? If life really makes any sense?

Meet SPREADS!

Spreads is an always-terminating, well typed spreadsheet. Based on the Morte language, Spreads allows you to:

• Define functions!
• Always terminate!
• Have a reasonable COUNTIF interface!
• Have a reasonable VLOOKUP, HLOOKUP, MATCH and friends interface!

Furthermore, Spreads has a layers concept, that allows you to clearly separate the Presentation of a value and the Value in itself. No more "What the hell, favourite spreadsheet, 5 is not a string?"

Status

Spreads is not really itself yet. For now, this repo should be seen as a very early stage prototype. Notable missing elements are:

• Almost all of normal spreadsheet functions!
• Arithmetic functions!
• Documentation!
• Almost everything!

If I were to risk designing a plan, I would say it would be the following:

1. Come up with a reasonable way to infer some types (for arithmetic operations).
2. Come up with a reasonable way to print multiline functions.
3. Iron out details about how the Presentation layer works.
4. Complete the standard library.
5. ???
6. Profit

Is it any good?

Not yet.

I really want to try this early stage prototype that does nothing except having a multi-cell Morte interpreter, how do I do it?

• Clone the repo
• Install the haskell tool stack
• stack setup
