2048 - Exercice de style

This is a small game mimicking 2048. There are three big differences:

• You decide where the numbers appear
• It is terminal based
• There are no points

It is not particularly fun, nor useful. This was an exercise/proof of concept.

Building

Using stack, run stack build.

Playing

To start the game, run stack exec 2048-lens (or use giak). The board looks like this:

X X X X

X X X X

X X X X

X X X X

In order to insert numbers, enter the following:

[row] [col] [value]

and hit <return>. [row] and [col] can be one of the following: x, y, z, w. [value] must be an integer, like 256. For instance:

x w 2

will transform the board as follows:

X X X 2

X X X X

X X X X

X X X X

Then, enter either h, j, k or l (followed by <return>) to move the board around like in the original game.

But why though?

I though it would be nice to define the update function for a single row, and be able to apply it anywhere, in any direction, in the game matrix. The linear package allows you to do just that.
