@jumblerg: I've been trying to get hoplon.ui working as a library. I'm still getting errors like 'WARNING: Bad method signature in protocol implementation, hoplon.core/IHoplonParent does not declare method called -append-child! at line 51 C:\Users\rigalo\.boot\cache\ tmp\Users\rigalo\Desktop\Dev\hoplon\ui-demo\9m4\-x19f70\index.html.out\hoplon\ui\elems.cljs'

Do I clone hoplon into the hoplon/ui project directory (v2) before i 'boot build'?

clone hoplon and boot build-jar

then boot build-jar in hoplon/ui

Ok, I think I missed that step. I'll try it now.

@jumblerg: It's compiling without errors!!! Thanks. My git-fu is weak..

Can you give me a simple basic function snippet to test in the browser.

excellent

I'll start digging for the api though..

Is there a hlisp function that will pretty print and arbitrary cljs data structure to html?

hlisp doesn't create any data structures

you get the DOM elements directly

Sorry I was unclear. I have the datastructure, a deeply nested map. Is there a hlisp function that will turn it into some readable html?

not that I'm aware of. There's nothing in Hoplon that operates on data structures.

@mac: you can do something like this

(pre (cell= (with-out-str (cljs.pprint/pprint data))))

in the sense of HTML representation

(need to have [cljs.pprint] in you :require statment)

jjttjj: That works, thanks.

@mac: i bet there is something like a html representation of clojure data in the code for the google chrome clojurescript extension

like so you can print in the console with collapsible vectors, maps, etc

micha: That was the kind thing I was looking for.

are there any examples out there using castra and transit to communicate jodatime dates?

@jjttjj: i think perhaps converting them to java.util.Date before serialization might be an easy way to get it working

otherwise you could use the transit extension mechanisms to add support for joda

@micha have you seen this? https://github.com/kennytilton/its-alive

@bsima: yep

how do you like it?

idk, haven't had a chance to look into in depth

i guess it moved here -> https://github.com/kennytilton/rube

i have to look deeper into it

and build something with it

at first glance the code looks like common lisp moreso than idiomatic clojure, which is understandable considering the author

yeah it's more of a complete FRP solution

javelin only does a small fraction of that

which is part of javelin's appeal, if you ask me...

yeah by limiting it we can make some things work, like formulas with side effects for instance, without needing more primitives

i'm interested to see if he's found a way to get around the weak reference problem in his cljs implementation

like the lack of weak references in js

I'm not super familiar with the weak reference problem... how does javelin solve it?

i think it's impossible to solve in js, but maybe he's found some clever workaround

the problem is that cells need to hold references not only to the cells they depend on, but also to the cells that depend on them

we'd like to have the references to the cells that depend on them be weak refs, so the cells that depend on them can be GC

the "sinks", basically

so in javelin they never get garbage collected, just removed from the sink when it's cell is destroyed https://github.com/hoplon/javelin/blob/master/src/javelin/core.cljs#L55

right, you can manually detach them, then they can be collected

but that's kind of useless in most cases

hmm, I can't figure out how tilton does it. I think he just removes them like javelin does, but i can't really tell... ¯\(ツ)/¯

ideally you wouldn't need to call destroy-cell! explicitly
