setYear is not a function when parsing dates

[iwsmith]

I am pretty sure this is a case of me being dumb, but I am getting an error whenever I try to parse a date:

iwsmith-site.core=> (format/parse (:basic-date format/formatters) "20150501")
#<TypeError: p1__22659_SHARP_.setYear is not a function>
         cljs.core.merge_with.call.cljs_time.internal.core.valid_date_QMARK_.call.cljs.core.reduce.call.vec__22697 (jar:file:/Users/iwsmith/.m2/repository/com/andrewmcveigh/cljs-time/0.3.7/cljs-time-0.3.7.jar!/cljs_time/format.cljs:395:29)

My namespace is configured as follows:

(ns ^:figwheel-always iwsmith-site.core
    (:require [om.core :as om :include-macros true]
              [om.dom :as dom :include-macros true]
              [cljs-time.core :as time]
              [cljs-time.format :as format]
              [sablono.core :as html :refer-macros [html]]))

And project.clj:

[com.andrewmcveigh/cljs-time "0.3.7"]

Thanks for taking a look!

Hey,

I've not seen this before, but I think it's got something to do with figwheel, and/or the compilation settings. I've managed to reproduce something similar so I'll take a look.

[iwsmith]

Awesome! Let me know if I can help out in anyway.

Just incase I've included my project.clj below.

[andrewmcveigh]

So the problem at my end is that if you start figwheel before you've done:

(ns ...
  (:require [cljs-time.format :as format]))

(format/parse (:basic-date format/formatters) "20150101")

...

... then the namespace doesn't get properly compiled in (or maybe at all?). I've not used figwheel enough to know if this is a trait of figwheel, or something to do with the library, though I'd lean toward it being a problem with the default compilation options of clojurescript clashing with the live-reloading of figwheel.

Could you check if the above is true your end? (first write the code, then restart figwheel)

[iwsmith]

Interesting, that does seem to fix it. I guess we can chalk this up to user error or strange figwheel magics.

Thanks!
