@jamiei: do you have example code?

seems dependent on what you’re doing in the defroutes

Hey guys is there a library or a tutorial that I can use for learning how to handle touch events in clojurescript?

My reagent components only have on-click events and I am wondering if I should use something like this: http://benhowdle.im/touche/

or handle them myself.

@kidpollo: I’ve used the popular hammer.js for touch events in cljs

cljsjs has it packaged here: https://github.com/cljsjs/packages/tree/master/hammer

cool cool thanks

@shaunlebron: Something like this example: http://pastebin.com/iaHCRCMh - Do I need to use shared state to communicate which contact id is being viewed to the component view?

@sander, thank you! The :nrepl-port setting was commented out in my project.clj.

I refactored a util namespace into a folder, so that qt.utils -> qt.utils.core, and now I'm seeing Uncaught ReferenceError: goog is not defined in the browser console on force-reload, but everything compiled OK. I have tried lein clean, a bazooka rm -rf of public resources and (reset-autobuild). What am I doing wrong?

Looks like this was related to trying to run a cljs-repl from Cursive 😕

@petrus: Why is that?

@cfleming: when I stopped my Cursive cljs-repl and relied on the repl in lein figwheel only, it started working again. But it could have been some weird repl state.

Does anyone have a "time remaining" function lying around that humanises seconds to "5 days", "4 hours", "32 minutes"? Would save me some time.

@petrus: There was a lib mentioned in the Clojure Cookbook, but I don’t remember the name - humanize, perhaps?

@petrus: goog.date.duration

@petrus: https://github.com/google/closure-library/blob/eb26f425dbd99a70d2955d8fcc892f2fd0178acb/closure/goog/date/duration_test.js

@rauh: that’s neat, do you generally find useful things in goog by looking through tests?

@shaunlebron: Actually, yes that's the first think I consult. Github's search made a few things obsolete for me. The goog closure docs are aweful all together. I just entered "hours minutes" in the search box in the closure github repo and it came right up

haha cool

I thought this was a good attempt: http://www.closurecheatsheet.com/

A global github search with "extension:cljs" or "filename:project.clj" is done many times a day

missing some things though

noted + changed link: thanks @tcrayford

@shaunlebron: Yeah that cheat sheet is cool indeed. I always like examples. I bookmakred that the other day. But I forgot it exists already

@rauh, I guess the global search you just mentioned is not related to your closure searching?

@shaunlebron: No, i sometimes use one or the other. When I need more examples for cljs then I do a global wide search limited to extension and search for "require goog.foo.bar" for instance

wow, that’s powerful, never thought to do that

I even added a search keyword to chrome so I can search it really really quick

I do the same for emacs lisp often. There is just soo many examples out there

hey! I’m using om-sync and, following the Readme example, I get two strange things:

anything I tag with :create ends up sending the whole :coll to the server, not only the element I tagged ([:create new-element])

and anything I tag with :delete sends nothing, even if I tag it with [:delete thing-i-just-deleted]

any ideas? :S

@txus maybe best ask in #C06DT2YSY chan

oh nice! didnt know

added a new wiki entry for using Google Closure Library in ClojureScript (based on @bostonou’s blogs, and @rauh’s searching strategies): https://github.com/clojure/clojurescript/wiki/Google-Closure-Library

corrections and stuff appreciated!

Thanks for that!

@jamiei: it has to go in your app state somewhere or shared state when your defroute is executed

check out #C06DT2YSY chan to see what they say

when I’m chasing down an advanced compilation bug, I typically have to lein do clean, cljsbuild once prod, i.e. auto prod doesn’t seem to pick up changes to my externs.js file. Is there a faster way?

a full recompile takes ~120s

@mfikes just sent email

@mfikes awesome! Running it now, I might have to make a lisp keyboard for this...

@brettevans: That would be useful!

I'm struggling to run my cljs tests using is from cljs.test. Trying to run tests from the REPL throws: cljs.test Cannot read property 'do_report' of undefined> clojure.core/ex-info (core.clj:4591). Running lein test runs zero tests. How do I get lein test to run my ClojureScript tests or fix my code so I can run tests from the REPL?

@petrus I think it's should be "lein cljsbuild test" instead

You can make an alias in your project.clj

@arohner: I would verify that built-in auto-building (a la Quick Start) exhibits the same issue.

that said, ~120s to build seem excessive to me (I've never seen it take that long even for super massive projects).

If you're not compiling 60,000 lines of ClojureScript, usually means you need to tweak your JVM settings.

@dnolen: thanks

@dnolen: are there any CLJS-specific optimizations, or just the usual stuff about -server, Xmx, GC algo?

@arohner: Google Closure advanced compilation is very RAM hungry. Try 1g, then 2g etc.

@arohner: would also use the :verbose compiler option to get a view into where things are stalling. There are a couple of other known issues if your project is large.

I only have 1-2k of CLJS

lol

but I’m also using jQuery as a foreign lib

yeah 120s doesn't make sense then

Closure will never see jQuery

the other issue, a known polynomial problem with :recompile-dependents. Try setting this to false.

@mfikes: so awesome! And only 3 day after EuroClojure

@dnolen: the app?

yes the iOS REPL

@dnolen: I was away from computers for a week (London trip). Perhaps I pent up the need to do something related to ClojureScript. But, seriously, you enabled this. Joel pushed it over the edge.

@dnolen: I had / have a fear of Apple rejection based on the app being too “simple.” But there are many human-years of effort underneath it enabling it to exist.
