@twashing I think your "completing" arity needs to do something with state (the [accumulator] arity).

Hmm, you're returning c' from the 2-arity branch... that would lose the accumulator value... is that what you intended?

@seancorfield I’m wanting to return the joined values that are in c', to the result list.

So part B, vs part A.

...
;; A
record {:uuid 1, :last-trade-price 11.1}
record {:uuid 2, :last-trade-price 11.2}
record {:uuid 1, :last-trade-price-exponential 10}
record {:uuid 2, :last-trade-price-exponential 11}
record {:uuid 3, :last-trade-price 11.3}
record {:uuid 3, :last-trade-price-exponential 12}

;; B
c' {:tick-list {:uuid 1, :last-trade-price 11.1}, :ema-list {:uuid 1, :last-trade-price-exponential 10}, :sma-list {:uuid 1, :last-trade-price-average 10.1}}
c' {:tick-list {:uuid 2, :last-trade-price 11.2}, :ema-list {:uuid 2, :last-trade-price-exponential 11}, :sma-list {:uuid 2, :last-trade-price-average 10.2}}
c' {:tick-list {:uuid 3, :last-trade-price 11.3}, :ema-list {:uuid 3, :last-trade-price-exponential 12}, :sma-list {:uuid 3, :last-trade-price-average 10.3}}

does someone know if its possible to load a keras model in clojure and make predictions with it?

how to I expand/resolve this to an absolute path? "/Users/me/foo/../bar"

i see Java has a class called “Paths”, you could maybe run it in and out of that?

yeah I'm playing with that... no luck (-> "/Users/me/foo/../bar" (Paths/get (into-array String [])) .toAbsolutePath str) ;; -> dumb result which still has '..'

hah

user=> (require '[ :as io])
nil
user=> (require '[clojure.string :as str])
nil
user=> (def path "/Users/james/foo/../bar")
#'user/path
user=> (-> (apply io/file (str/split path #"/")) (.getCanonicalPath))
"/Users/james/bar"

ah damnit

the canonicalfile one works but absolutepath returns the thing without it collapsed

there we go…getCanonicalPath is the one

Nice! Had gotten this one meanwhile

(-> the-path (Paths/get (into-array String [])) (.toRealPath (into-array [java.nio.file.LinkOption/NOFOLLOW_LINKS])) str)

lol

Hi here! I studied clojure in the past months, and in the following weeks I would like to propose it to my company to rewrite an old background job we have. The alternative to Clojure would be to rewrite it using JavaRx. For what I understood the async module plus the transducers can do the same job as RxJava in clojure, but the fact that I can't find any tutorial/guides/resources about it make me doubt that I'm not on the right track. Am I looking at the right modules to do it? Do you know any resource to do it?

Is it a bad idea to have keywords that begin with a number? Like :1234

you won't be able to destructure them

It’s bad-ish, in that it will prevent you from doing :keys destructuring and cause issues any other time you try to turn it into a symbol

but clojure.core/keyword will happily create kws for any string, including "", so by that definition anything goes

I believe at the moment, clj allows them and cljs does not

this is a long unresolved point of syntax

I think it’s unlikely we will ever make them stop working in clj

works in cljs too

> (-> "1a" keyword name keyword)
:1a

at least in bootstrapped cljs

They seem to work in both clj and cljs. Emacs doesn’t highlight them as keywords and it got me worried.

yup works in JVM cljs as well

As it seems like it’s gray area I think I’ll use strings instead. Thanks for the answers @pesterhazy @michael.gaare @alexmiller

I was talking about reader support, not the keyword function

also works

maybe this got changed though in 1.10

when compiling non-self-hosted cljs you are still running in clojure, so it accepts keywords clojure does. if you read a keyword using cljs code (eg read, edn/read) cljs will reject those keywords

iirc

if you’re parsing from json (or converting from any javascript object for that matter) it is definitely possible to get numeric keyword keys in a map in clojurescript:

(js->clj #js {"1" "val"} :keywordize-keys true)
=> {:1 "val"}

that’s from a browser connected cljs repl

right, keyword function accepts any garbage

but the cljs reader is more picky than the clj reader

oh i understand what you and alexmiller are saying now 🙂

would it be horrible if i wrote a transducer that mostly depended on a state-transition chart bound into it at creation?

just trying to sorta wrap my head around using them for parsing

no

@martinklepsch I just hit the https://cljdoc.xyz/d/com.bhauman/spell-spec/0.1.0/ endpoint and no dice https://clojars.org/com.bhauman/spell-spec

hello guys

has anyone used scjsv jsonSchema validator

Do people make much use of dependency injection libraries such as integrant, component or mount?

I use Duct (which is based on integrant) everyday. Very happy with it

i've been looking at codependence for that

I use component whenever I start writing a new service
