Clojurians Log v2

Trying to integrate https://github.com/nadbm/react-datasheet into a re-frame project. `(defn main-panel []   (let [name (re-frame/subscribe [::subs/name])]     [:div      [:h1 "Hello from " @name]      [(r/adapt-react-class ReactDataSheet)       {:data [[{:val 1} {:val 2}] [{:val 3} {:val 4}]]        :valueRenderer #(:val %)}]]))` This results in: <div><h1>Hello from re-frame</h1><span tabindex="0" class="data-grid-container"><table class="data-grid"><tbody><tr><td class="cell"><span class="value-viewer"></span></td><td class="cell selected"><span class="value-viewer"></span></td></tr><tr><td class="cell"><span class="value-viewer"></span></td><td class="cell"><span class="value-viewer"></span></td></tr></tbody></table></span></div> So no data is visible. Am I doing something wrong?

Maybe #re-frame and/or #react channels will have folks with more knowledge @dumrat?

12:07 AM I have this:

(def op ["+" "-" "*" "/"])
((first op) 4 3)

Hello! I am searching for information on solutions on how to synchronize debit/credit transactions in Clojure. I am thinking to have a database as well. I want to have atomic operations. But maybe possibly have good performance. Please suggest any hints, articles, advice, books, etc...

"+" -> +

for a high level overview http://dataintensive.net is very good

((resolve (symbol (first op))) 4 3)

Hi. Please may I ask some advice on clojure.spec.alpha? I’d like to generate the definition for the contents of a map from an existing vector I’m already using elsewhere. I naively tried this:

(def field-names ["PCD2" "PCDS" "DOINTR" "DOTERM" "OSEAST100M"
                  "OSNRTH100M" "OSCTY" "ODSLAUA" "OSLAUA" "OSWARD"
                  "MSOA11" "CALNCV" "STP"])

(s/def ::postcode-data (s/keys :req (map #(keyword (str *ns*) %) field-names)))
(s/describe ::postcode-data)
(s/valid? ::postcode-data {})

@delaguardo that's what i needed. thanks.

It's not easy with Spec 1 but it will be easier with Spec 2 -- although that isn't ready for production use yet.

What we've done at work is go the opposite way: we start with the spec, then get its form and pull the list of keys out and use that programmatically @mark354

@mark354 there is also Malli which just hit 1.0 https://github.com/metosin/malli

How to express in deps.edn with clj (CLI) to place a directory in classpath for yogthos/config? I have environment definitions at config/dev/config.edn thus I need to have config/dev on the classpath. I figured out the following deps.edn would work, but looks ugly:

{:paths
 ["src" "config/dev"]
 :deps
 {org.clojure/clojure           {:mvn/version "1.10.1"}
  com.datomic/datomic-pro      {:mvn/version "1.0.6202"} ; for peer API, found the version number in the Datomic software installation directory, and has to insall by bin/maven_install
  org.postgresql/postgresql     {:mvn/version "9.3-1102-jdbc41"}
  http-kit/http-kit                      {:mvn/version "2.4.0"}
  metosin/reitit                {:mvn/version "0.5.5"}
  yogthos/config                {:mvn/version "1.1.7"}}
 :aliases
 {:server {:main-opts ["-m" "grok.core"]}
  :dev {:extra-path ["config/dev"  "env/dev"]}
  :test {:extra-paths ["test" "config/test"]
         :extra-deps {lambdaisland/kaocha           {:mvn/version "0.0-529"}
                      lambdaisland/kaocha-cloverage {:mvn/version "1.0.63"}}
         :main-opts ["-m" "kaocha.runner"]}
  :socket-repl {:jvm-opts ["-Dclojure.server.repl={:port,50505,:accept,clojure.core.server/repl}"]}
  }}

@yubrshen this line

:dev {:extra-path ["config/dev"  "env/dev"]}

If you're using aliases for :dev, :test, then you wouldn't need "config/dev" in :paths I think?

@seancorfield Thanks! Amazing you know the answer before my finishing my question!

And then when you build for prod? Or is that just the default?

I hope so, after your correction.

@seancorfield Thanks a million! You're right. With your corrections, the following works:

{:paths
 ["src"]
 :deps
 {org.clojure/clojure           {:mvn/version "1.10.1"}
  com.datomic/datomic-pro      {:mvn/version "1.0.6202"} ; for peer API, found the version number in the Datomic software installation directory, and has to insall by bin/maven_install
  org.postgresql/postgresql     {:mvn/version "9.3-1102-jdbc41"}
  http-kit/http-kit                      {:mvn/version "2.4.0"}
  metosin/reitit                {:mvn/version "0.5.5"}
  yogthos/config                {:mvn/version "1.1.7"}}
 :aliases
 {:server {:main-opts ["-m" "grok.core"]}
  :dev {:extra-paths ["config/dev"  "env/dev"]}
  :test {:extra-paths ["test" "config/test" "config/dev"] ; added "config/dev" for 'clj -M:test --watch' to work
         :extra-deps {lambdaisland/kaocha           {:mvn/version "0.0-529"}
                      lambdaisland/kaocha-cloverage {:mvn/version "1.0.63"}}
         :main-opts ["-m" "kaocha.runner"]}
  :socket-repl {:jvm-opts ["-Dclojure.server.repl={:port,50505,:accept,clojure.core.server/repl}"]}
  }}
