I'm trying to use Happy for the first time, and I'm having trouble with this
very simple example:
= BEGIN: PolyParser.y =
{
module Main where
import Char ( isAlpha, isDigit, isSpace )
}
%name calc
%tokentype { Token }
%error { parseError }
%token
id { TokenId $$ }
I often use SciTE for editing Haskell code. I wanted an easy way to type symbols
such as ∀ (instead of forall), so I created a properties file that allows me
to do that. I haven't seen anything similar online (I Googled first), so I made
the code available online.
You can find the file and
I wrote a library called AmysGeometry. The only modules in it (so far) are:
Amy/Geometry/ThreeD.hs
Amy/Geometry/UnitSphere.hs
The library compiles just fine, and I've been using it with other programs for a
while. Then yesterday, I started getting the following error.

have you tried cabal clean before cabal install ?
Yeah, forgot to mention that I'd tried that.

Looks nice. Does it scale well to millions of elements, and can it handle 3D?
The current implementation wouldn't scale well to millions of elements, but it
shouldn't take much tweaking to support that. Currently, when a grid is
constructed, the
It seems like you should be able to stick this behind some abstraction
so that you can support multiple implementations for grids (i.e.,
currently storing indices as you mention, but could support other
implementations with different trade offs ...)?

Yes, there's a Grid typeclass

formatted improperly...
Cheers! I'll fix that.

WHAT'S NEW:
The GridMap module provides ordered maps from tiles on a grid to values. This
module is a wrapper around Grid and Map, in order

After taking a peek at the documentation: have you considered removing
the size function from Grid?
. . .
It might also be useful to add a rectangular grid type where diagonally
adjacent cells are also neighbors.

Another interesting idea
I'm happy to announce a new major release of the grid package:
http://hackage.haskell.org/package/grid
https://github.com/mhwombat/grid/wiki (wiki)
WHAT'S NEW:
* The package now uses associated (type) synonyms instead of
multi-parameter type classes with functional dependencies.
*
Also again, taking this way I can not provide several constructors taking
inputs of different types, can I ?
You can have multiple constructors, taking different numbers and types of input
parameters, yes.
