more_functional

Hello @DrBoolean,
thanks for your great collection of functional techniques for JS!
I already used several functions from it, but today I tried to load the whole thing and got

Error: Cannot find module './more_functional'

Am I missing some file, do I have to rename something, or is this dependency not necessary?

Hi major-lab.

That's great to hear you're playing with it!

That's an artifact. I apologize, this sways from being ready to use and totally in dev.

more_function is what we called the Prelude library beforehand. So if you remove that dependency and require prelude.js instead, all should be well.

Hope that helps!

Hi,
thanks for your help, that worked indeed, but I got a new error.
I try to do pattern matching, and am missing the function groups_of apparently:

        throw e; // process.nextTick error, or 'error' event on first tick
              ^
ReferenceError: groups_of is not defined

Do you have this somewhere?

[DrBoolean]

Haha man, we gotta clean this up
groups_of should be groupsOf

Ok, here we go 😃
Now i am missing $:

        throw e; // process.nextTick error, or 'error' event on first tick
              ^
ReferenceError: $ is not defined

Is that for pattern matching?

I haven't used that in a bit...

I think we're mainly supporting these now:

https://github.com/loop-recur/FunctionalJS
https://github.com/loop-recur/PreludeJS
https://github.com/loop-recur/typeclasses

Which should get ya most of the haskell goodness. I think the pattern matching library ended up being less useful than we though so we dropped it.

Oh, how unfortunate.. i was just trying out pattern matching.
Anyways, thanks for the library, it is great so far!

No prob.

To answer your previous question, btw I think you can do something lik this:

var $ = Match.parameter;
var _ = Match.wildcard;

Color = Data(function(){ return ({ Red: {}, Green: {}, Blue: {}, Yellow: {} })});
Point = Data(function(){ return ({ Pt: { x: Number, y: Number, color: Color } })});

var points = Match (

Red, function() {
return "Was Red";
},

Pt(1,$, _), function(n) {
return "Was"+n;
},

Green, function() {
return "Was green";
},

$, function() {
return "nah";
}
);
