Clojurians Log v2

which version of clojurescript did you use before? macros don't just work like that in CLJS unless you use nbb or so

in cljs i put the macros in a .clj file, and in cljs with same name i used require-macros, my version was [org.clojure/clojurescript "1.10.866"]

i am overriding clojure.core symbols thats why want q to be local scope with those, for example this is a mongodb query, and inside it, i use clojure.core/cond for example to refer to the clj one :

(q :people.workers
   (< :salary 1000)
   (> :years 1)
   {:children (filter (fn [:child.] (< :child.age. 15)) :all-children)}
   (>= :children 2)
   {:bonus (reduce (fn [:total. :child.]
                     (cond (< :child.age. 5) (+ :total. 100)
                           (< :child.age. 10) (+ :total. 50)
                           :else (+ :total. 20)))
                   0
                   :children)}
   [:!id :name {:new-salary (+ :salary (if- (> :bonus 200) 200 :bonus))}]
   (sort :!new-salary))

i made mongodb query to be as if we write clojure https://github.com/tkaryadis/squery-mongojs

you need to do a similar thing for squint, you need to use :require-macros but currently you can't use the same filename and the file has to be .cljs or .cljc you also need to add a squint.edn where you add :paths ["src"] and put the code into a source directory. so e.g.

(:require-macros [takis.macros ...])

i read this in documentation, and i tried but i failed, do you know why this code doesn't work?

(defn add [& es]
  {"$add" (vec es)})

(def operators-mappings
  '[+_ add])

what do you mean with "doesn't work"?

aaah I know

the quote doesn't work in squint, since symbols don't work in squint, they do not exist. but they work in macro namespaces

squint only has JS data structures, no symbols or keywords

keywords are translated to strings

symbols simply don't exist

if you move this to the macro namespace they should work since symbols do exist at compilation time

ok thank you, is there a simple example of using a macro in squint?

how to create one and use it

I'll make an example project, after lunch

thank you, anytime you can : )

i made it working ike it worked in clojurescript, with 2 namespaces : macros.cljc

(ns macros)

(defn add [& es]
  "aaa")

(def operators-mappings
  '[+_ add])

(defmacro q [args]
    `(let ~operators-mappings
       ~args))

(ns macros
  (:require-macros [macros]))

(ns App
  (:require [components.ExpenseItem :as ExpenseItem])
  (:require-macros [macros :refer [q]]))

(defn add [& es]
  "aaa")

(str (q (+_ 1 2)))

seems fine 🙂

indeed! that's how you do it
