15:14 <kings> hi

15:15 <kings> adambeynon hey

15:16 <kings> anyone around

15:18 <kings> ive managed to get my d3 wrapper working mostly

15:19 <adambeynon_> kings: hi

15:20 <kings> adambeynon i have 1 more question

15:20 <adambeynon_> Good that it's working. What's left to fix on it?

15:20 <kings> my main problem was that jquery was returning a function and d3 was returning an object

15:20 <kings> so now i have sorted out that

15:20 <kings> but im trying to get the auto expose working

15:21 <kings> so ive taken the expose methods from the jquery one

15:21 <kings> but in it this part i dont understand

15:21 <kings> there is a loop

15:22 <kings> and int he loop self._proto[method] =

15:22 <kings> this is used to assign the method to the ruby wrapper class

15:22 <kings> but in jquery i guess thats fine but it doesnt work for my implementation

15:23 <kings> so how do i dynamically append a method to my class

15:24 <kings> self[method] = doesnt work

15:24 <kings> i dont have any prototype on d3

15:25 <adambeynon_> kings: ok. never used d3 before, so let me read up on how it works

15:26 <kings> http://pastie.org/8767656

15:26 <kings> here is my selector implementation

15:27 <kings> but i dont want to have to hand code every single method

15:28 <kings> on my ipad again so excuse typos etc

15:29 <adambeynon_> kings: ok, so by assigning the @selected ivar, it looks like you are actually wrapping a d3 instance

15:29 <adambeynon_> is that the intention?

15:30 <adambeynon_> opal-jquery is a bridge, rather than a wrapper, in that Element instances are the same object as a jquery instance

15:31 <kings> well bridging didnt seem to work so thsts why wrapping the d3 instance

15:32 <kings> ideally bridging would be great - but looks like i dont have the skills for that!

15:32 <kings> d3 returns an object and d3.select returns a function

15:32 <kings> whereas jQUery returns a function

15:33 <kings> so trying to extend d3.select didnt work for me

15:33 <kings> as it looks like the jquery one is geared up to work with a function

15:45 gravityblast has quit [Client Quit]

15:46 <adambeynon_> kings: looking at the code, I think wrapping is the better idea

15:46 <adambeynon_> I will need to read up on d3 some more though

15:46 <adambeynon_> there must be a prototype exposed somewhere

15:46 <kings> yeah bridging looks hard

15:49 <kings> d3 is not object oriented its more functionl so i dont think there will be any prototypes

15:56 <kings> adambeynon - instead of doing the expose like the one in jquery

15:56 <kings> can i do something like define_method instead

15:58 <kings> define_method :html { '#{@selected}['html']} for example

19:27 <dragonkh> hi

19:27 <dragonkh> adambeynon_: thanks for you help ealier looking at d3

19:27 <dragonkh> hi meh`

19:31 <meh`> dragonkh, hi

19:33 <dragonkh> meh`: quick question - when in javascript something takes a function

19:33 <dragonkh> how does it look in opal?

19:33 <dragonkh> e.g. circle.attr("cx", function() {

19:33 <dragonkh> return Math.random() * w;

19:33 <dragonkh> });

19:33 <dragonkh> attr takes a string and then a function

19:33 <meh`> Native(`circle`).attr("cx", -> { rand * w })

19:33 <meh`> or proc { rand * w }

19:34 <meh`> procs are normal js functions

19:34 <dragonkh> ah cool

19:34 <dragonkh> thanks

23:01 <dragonkh> evening

23:01 <dragonkh> hey elia

23:01 <elia> hey dragonkh !

23:01 <dragonkh> hey adambeynon_

23:01 <ryanstout> hey

23:01 <meh`> evening

23:01 <dragonkh> hey meh` and ryanstewart

23:01 <dragonkh> ryanstout

23:01 <dragonkh> even

23:01 <elia> lol

23:01 <ryanstout> evening

23:02 <dragonkh> I've been trying to write an opal wrapper for d3

23:02 <dragonkh> it's been pretty painful because unlike the jquery one - it's not prototype based - so it's very hard to write a bridge

23:02 <elia> seems that ppl on the parley list are calling for an opal episode on ruby rogues

23:02 <elia> that would be awesome

23:02 <dragonkh> so I'm wrapping instead

23:03 <dragonkh> um elia - I didn't understand much of that

23:03 <dragonkh> what is the parley list - what is ruby rogues

23:04 <elia> http://rubyrogues.com is a famous Ruby podcast (feat. avdi grimm, josh susser, jegII, …)

23:04 <elia> parley list is their private forum that you can join by paing 10$/y

23:04 <dragonkh> dont know those guys

23:04 <dragonkh> what they do?

23:04 <dragonkh> oh I see

23:05 <elia> e.g. jegII wrote the csv lib for MRI 1.9.3

23:05 <dragonkh> fastercsv?

23:05 <elia> yep

23:05 <elia> and other stuff I think

23:05 <elia> big ruby player back in the days

23:06 <elia> his blog http://blog.grayproductions.net
