I’m planning on working on it tomorrow

I’d say give it a couple of weeks and expect changes - clojure.spec is still evolving

"ANALYSIS ERROR: Unmatched delimiter ) on file null, line null, column null" welp lein, not sure what you want from me

: (

syntax error - you have an unbalanced parenthesis. you should use something like paredit http://danmidwood.com/content/2014/11/21/animated-paredit.html

aha, updating clojure seems to have helped

dabra it's more the null file, column that's blockin me, hah

that said, I shouuuld learn paredit at some point

is there a good clojurescript linter anywhere? Maybe auto formatter?

once you’ve learned you’ll curse yourself for not learning it earlier

clojurescript is my first foray into lisps

😄

there’s no syntax in lisp (or it’s very minimal) so linters are not popular. there’s no syntax to check

eyy

generally you just evaluate forms inside your editor

Linters these days usually give use best-practicey sorts of stuff which I like a lot

but sure

there’s https://github.com/jonase/eastwood

it’s nice to have, unlike javascript where jslint is a must

dabra: that looks great!

I consider linters a must in general. Lightweight, make me worry less, automatically happens on save

what's not to love? 😄

yeah except in clojure saving you evaluate much more often than save

but try it out… good luck

What do you mean?

in clojure you build your program interactively within your editor

or in the repl

Could you describe further for me the former?

anyway eastwood works for clojure, not for clojurescript

sec i’ll send you a link

I am using lein with figwheel so I dooo expect things to refresh in realtime

if that's..sort of what you're mentioning

something like that. https://www.youtube.com/watch?v=LiA56W3V3_w

Hello! I want to use cljsjs/selectize but not like this (.selectize (js/jQuery (.getElementById js/document "#dropdown")))

Instead I want to create a fn that can generate a select, without bothering about any id

How could I do that?

Thanks in advance!

@leontalbot: make a function that wraps it?

Yes, something like (defn select [selectize-args body] ...)

how do you expect to call it?

@dabra : Hello I am very new to clojurescript. I have used clojure for a year , but not clojure script. Do you know if I can use vim to connect to figwheel.

Oh my god, I have javascript fatigue, and I'm not even using javascript.

where are things like "#js" and "js*" documented?

they are not on https://github.com/clojure/clojurescript/wiki/Differences-from-Clojure

and they are hard to Google 🙂

@nothingdhsp: You can connect to Figwheel with vim-fireplace. I had to apply a pending pull request to vim-fireplace to support configuring the repl environment.

@jcromartie: http://cljs.info/cheatsheet/ (not official though)

@jcromartie: this is better: https://github.com/cljsinfo/cljs-api-docs/blob/catalog/refs/syntax.md

thanks those are great

I found the cheat sheet but it didn't mention js*

and neither does the syntax ref

I wonder if it's safe to use

if it's undocumented

will it go away in the future?

what does it do? It's new to me.

@jcromartie: js* is not safe to use, implementation detail

Thanks @dnolen

Is there anyway at the moment to make a synchronous http request in clojurescript? I need to make some http-requests before each of my tests run, and I need them to be synchronous, or at least complete before the other tests start.

At the moment Im trying to do it in the :before of the use-fixtures function.

@underplank: had you tried to use async tests? if you use cljs.test (the native one) it has this support: https://github.com/clojure/clojurescript/wiki/Testing#async-testing

I wasnt sure If I could do this in the :before block?

of use-fixtures? I guess its just a function/macro.

check the Async Fixtures on that same page, just after async tests 😉

facepalm

Hello all, trying to translate this but having a hard time from JS -> CLJS

var xScale = new Plottable.Scales.Linear();

(def x-scale (.Linear (.-Scales (new js/Pottable))))

@dviramontes: (def xScale (js/Plottable.Scales.Linear.))

note the . at the end

@dviramontes: I think your original is correct

it’s not, he wants to instantiate Linear and is instantiating Plottable

ah maybe "new" doesn't bind as tightly as I though it does in js

damn you, non-lisp!

new String.length (error) vs (new String).length

@anmonteiro: that worked! thanks ^^

Hi, anyone know if there’s some docs on using ES6 from ClojureScript? I’m looking at the foreign-libs portion of https://www.niwi.nz/cljs-workshop/, but still have some questions.

The reason is that I’d like to use the Phoenix Framework’s channel client (written in ES6 js) from CLJS.

are you trying to use an es6 module?

oh

you can bundle that into a standalone and then create an extern of it

thanks, when you say bundle into a standalone, do you mean compile to its own js file?

ah, I’ll take a look at this: http://lukevanderhart.com/2011/09/30/using-javascript-and-clojurescript.html

i mean using browserify to bundle into a umd module so you can use it like a regular js file

via --standalone

ah, okay, thanks

Poll: would you rather have async functions prefixed with "a-" or "a" ? 👍 for "a-", 👎 for just "a"

Hmm, personally I wouldn't want an indicator in the function name. I prefer function names to explain "what" not "how"

This seems relevant: https://stuartsierra.com/2016/01/09/how-to-name-clojure-functions

These are io functions, the how is relevant

Well, given the two choices I guess I'd go with "a-"

Thanks

I’ve got a single page, reacty app (etc) and want to provide a button allowing folks to download a CSV file of data I have locally (not on the server). Any tips?

Oh, maybe this is it: http://stackoverflow.com/a/14966131
