yeah because its like "us flag" changes to "at flag" and more then 50 cards like this (its a search result)

currently i have this ugly thing here:

(defn country-flag [class]
  (with-let [elem (i)] (with-init! (.addClass (.removeClass (js/$ elem)) class))))

@peterromfeld you can remove classes

https://github.com/hoplon/hoplon/wiki/HTML-attributes-and-JS-events-%28on%21%2C-do%21%29

"Providing a map of classes as keywords with true or false is more verbose but allows us to enforce the existence or absence of a class. "

@peterromfeld additionally, this might be a use case for a data attribute

:data-country-flag current-flag

@thedavidmeister we are using semantic-ui, not sure how i would use it with data attribute

@peterromfeld then set the classes as keys of a map and true/false in the values

e.g. :class (j/cell {:us-flag true :at-flag false})

for all 250 countries in each of the 50 cards?

@peterromfeld yeah... the problem with class is that it's kind of "global"

you could do something with a watch maybe

like, stick false into everything in the old value

to clarify, i dont propose to change :class its how i use it most of the time.. just in this exception it would be nice to have :class! which acts little different

you could do something with lenses or a do-watch

(let [add (j/cell nil)
      remove (j/cell nil)
 (j/cell=
  {add true remove false}
  #(j/dosync
    (reset! remove @add)
    (reset! add %))))

something like that

generally though i really use data attributes for anything like this

i prefer having k/v data that i can control on a per-k basis than a big bucket o' vals

btw i just put my new method into index.cljs.hl and use :class! for this flag exception (dont want to reinvent something that my css framework provides)

works like a charm

cool, well you can also wrap the above in a defn and get cells for each card

e.g.

(defn flag-class-cell
 (let [n (j/cell nil)
       o (j/cell nil)]
  (j/cell=
   {n true o false}
   #(j/dosync
     (reset! o <@U3MG3NJCC>)
     (reset! n %)))))

Has there been an update to https://github.com/tailrecursion/hoplon-deploy-heroku for the new boot?

I commented out a couple of things that were obvious problems, hoping it'd work, and then got, "Wrong number of args (1) passed to: cli/argspec->cli-argspec". I'm sure this is just one more thing I need to learn at a deeper level, but I don't know what I'm doing here.

can you paste the whole stacktrace?

if you have one

that was from the last run... previous errors include java.lang.RuntimeException: No reader function for tag tailrecursion.boot.core/version java.lang.RuntimeException: Unable to resolve symbol: add-sync! in this context clojure.lang.ExceptionInfo: Unable to resolve symbol: add-sync! in this context

the java.lang.RuntimeException: No reader function for tag tailrecursion.boot.core/version error

that is a boot version 1 file

so that boot script won't work with boot2

can you paste the build.boot file please?

Yes, that was what I was asking. Is there a version for the new boot, by chance?

sure

#!/usr/bin/env boot ;#tailrecursion.boot.core/version "2.5.1" (set-env! :dependencies '[ ;tailrecursion.boot.core/version "2.5.1" [tailrecursion/hoplon "5.10.23"] [tailrecursion/boot.task "2.2.4"] [tailrecursion/boot.notify "2.0.2"] [tailrecursion/boot.ring "0.2.1"]] :src-paths #{"src"} :out-path "resources/public" :main-class 'hello-world.core) ;; Static resources synced to output dir ;(add-sync!

you can do boot -V to see the boot version

could you paste into a snippet please?

it's hard to read that

oh, ok, don't use slack much...

the + on the left

you can paste in there and it will do monospace fonts and whatnot

um, I'm seeing a + by direct messages?

give me a second, I'll get there 🙂

oh, ok, feeling dumb

ah i see a problem

(deftask heroku
  "Prepare project.clj and Procfile for Heroku deployment."
  [& [main-class]]

that's the issue there

you can fix it by doing this instead i think

(deftask heroku
  "Prepare project.clj and Procfile for Heroku deployment."
  [m main-class NAME str "The name of the main class."]

ok, let me try that. Sorry for being so slow. I use clj for gaming math and systemy things lose me quick.

yeah no worries

@john_tollison I recently updated hoplon-castra template and am aware of people using on heroku

(different method, jar based deploy, but can help you out if needed)

Yes, I found my way to that update. That was exactly what I was asking for initial. Thanks 🙂

*initially
