Hi, i'm building a small microservice worker that needs to access a database. I find myself writing some database helper functions which I know a different service I will write later will also have to use. What is the recommended way of seperating the helper functions out so I can use them from both apps?

@jlmr if they don't call for making a library out of them, I'd say duplicate them.

Learning to use the REPL with vim and fireplace. I did the Seesaw repl tutorial. The wen on to playing with some of my own stuff. I got this weird lower-case error:

user=> (use 'playground.core :reload)
CompilerException java.lang.RuntimeException: Unable to resolve symbol: lower-case in this context, compiling:(clj_http/util.clj:97) 

(ns playground.core
  (:require [clj-http.client :as client]
            [cheshire.core :refer :all]))

I posted this here because I could not find a seesaw or http channel and because I was LEARNING the REPL. 🙂

@llsouder lower-case is a function in clojure.string

which version of clj-http are you using?

@val_waeselynck Thanks, will do that for now. When would you consider it worth making a library out of it?

Easiest way to update the :selection key to true or false based on the label of the inner map?

[{:label "Users"
    :display-order 1
    :choices
    [{:label "Login"
      :description "basic login page"
      :selection false
      :display-order 1}
     {:label "Reset/Forgot Password"
      :description "link to reset password via email"
      :selection false
      :display-order 2}]}]

@josh_tackett with Specter: (setval [ALL :choices ALL #(= (:label %) "Login") :selection] :some-value your-map)

@schmee specter work for cljs?

yes!

just check the gotchas here: https://github.com/nathanmarz/specter#clojurescript

what about a good json libaray for cljs? @schmee

dunno one, sorry, I mostly use Clojure

[{:label "Users"
    :display-order 1
    :choices
    [{:label "Login"
      :description "basic login page"
      :selection false
      :display-order 1}
     {:label "Reset/Forgot Password"
      :description "link to reset password via email"
      :selection false
      :display-order 2}]}
{:label "NLP"
    :display-order 1
    :choices
    [{:label "ngrams"
      :description "basic sentence delimiters"
      :selection false
      :display-order 1}]}]

@schmee what about like this ^^^?

(spector/setval [ALL #(= (:label %) "Users")
                   :choices ALL #(= (:label %) "Login") :selection]
                  true app-selection-list)

@schmee does that work? ^^^

should work, but you want specter/ALL instead of ALL

@schmee nope didn’t work

(spector/setval [specter/ALL
                   #(= (:label %) (:label group-data))
                   :choices
                   specter/ALL
                   #(= (:label %) (:label selection-option-data))
                   :selection]
                  selection app-selection-list)

don’t know if this is the issue, but you have spector/setval instead of specter/setval

(o instead of e)

I am using [clj-http "3.6.1"]

is there an easy way to do something like (-> {} my-fun print my-other-fun print)? i need print to return the value it prints for this to work, though

(-> {} my-fun #(do (print %) %) my-other-fun #(do (print %) %)) doesn't seem to work

(-> {} my-fun (doto print) my-other-fun (doto print))

To make the anonymous function version work you need extra parens: (-> {} my-fun (#(do (print %) %)) my-other-fun (#(do (print %) %))) because -> just inserts the threaded value into the s-exp as the second item -- use macroexpand to see what happens...
