[ClojureScript] Using Angular as a view layer for re-frame

2015-05-25 Thread Sean Tempesta 
Hi everyone!

I've been a longtime lurker on the Clojurescript list, but since I'm rather 
stumped at the moment I'm coming out of my shell.  

First off, I'd like to genuflect to both Sweden and wherever Mike Thompson is 
from.  You guys have built something really cool, and I'm embarrassed to bolt 
something truly ugly onto such elegant software.

How ugly?  Well, Angular ugly.  The framework that only a mother could love.™ 
Why would I do I such a thing?  Well, I've been developing apps for the past 
couple of months and I just can't believe how nice Ionic 
 is.  It just works (most of the time) and I 
can target multiple platforms easily.  And if you pretend Angular doesn't 
exist, it's somewhat bearable.  

Which brings me to my problem: I can't figure out how to get a Reaction to kick 
Angular into doing ... whatever it is that Angular does (digesting?) to update 
the view.  I'm guessing Reagent (or maybe React) deref's the ratom and that's 
why this whole thing works?  Angular just sits there like a lump of ugly coal.  

So, at first I tried doing things the "Angular way", using $scope.$watch's and 
it leads to a rather hilarious demo:

http://clojure.tempesta.io/Re-Frame-Angular-Test/angularWatchSubs.html

[I'm not exactly sure what's going on there, but I'm guessing that the watches 
are always one value behind.]

So, then I tried directly watching the app-db atom, and it works perfectly:

http://clojure.tempesta.io/Re-Frame-Angular-Test/angularWatchAppDB.html

But I think that's not the right way to do it.  Any ideas?

Code is on Github here:
https://github.com/seantempesta/Re-Frame-Angular-Test

Both Angular examples and the Reagent version are on this test page:
http://clojure.tempesta.io/Re-Frame-Angular-Test/

So, I just saw Colin's post:

https://groups.google.com/forum/#!topic/clojurescript/jYjTCsyMRAA

and using Ratom/Run! seems to fix it.  I've updated my example code if anyone 
is interested in seeing it.  Please let me know if this isn't the right way to 
do this! :)

[ClojureScript] Explore the ClojureScript API

I designed an API reference for ClojureScript.  You can see the available 
symbols, how they relate to Clojure*, and track version history:

Pretty neat! And with Github's "t" shortcut you can pretty quickly pick up
a specific function. I like having the versions something was added and
removed so easily available. Nice work!

Phew, I'm glad it works.  That's a lethal looking brew you have boiling there.

Re: [ClojureScript] In Om, why does transact not update cursor value.

2015-05-25 Thread David Nolen 
om/value is the cached value that was seen at the start of render which is
useful to know. You need to deref if you absolutely need to see what the
current value is.

[ClojureScript] How to create UUIDs?

2015-05-25 Thread Colin Yates 
Hi all,

(UUID. "214ecb53-2815-492a-aa11-209843bef82a") gives "WARNING: Wrong number of 
args (1) passed to UUID at line 1 "

What's the correct usage?

Thanks!

pretty sure that's the correct usage. works for me at the quick start brepl 
(https://github.com/clojure/clojurescript/wiki/Quick-Start#browser-repl):

same success w/ the rhino and node repls here.

Use (->UUID "...").

The way uuids are constructed was recently broken to add support for a cached 
hash value. A public constructor was also added. Details:
