Hi!
I'm running lein figwheel app
And in controller I write the code to be executed with cljs.js/eval
I want that eval would see my defined functions.
Lets look at example below, especially on sstr function and button/on-click
callback:
(ns cljs-eval-example.core
(:require
[cljs.tools.reader :refer [read-string]]
[cljs.js :refer [empty-state eval js-eval]]
[reagent.core :as reagent :refer [atom]]
[reagent.session :as session]
[secretary.core :as secretary :include-macros true]
[accountant.core :as accountant]))
(defn sstr [ & prms ]
(apply str (flatten arms)))
(defn eval-str [s]
(eval (empty-state)
(read-string s)
{:eval js-eval
:source-map true
:context :expr}
(fn [result] result)))
(defn home-page []
[:div [:h2 "Welcome to cljs-eval-example"]
[:div [:a {:href "/about"} "go to about page"]]
[:div [:button
{:on-click #(eval-str "(println (sstr [ \"hello world!\" \"asda\" ]))")}
"let's compile!"]]
])
The problem is that sstr during evaluation is not visible.
I have read that eval can accept :ns attribute for opts and probably it defines
default namespace
but I have no idea how to use that. Any help?
I want to define set of functions and macros (I have read that these should be
in another compilation unit) which will be available during evaluation (in fact
I want to just execute the AST from another language).
Another question is if I write the whole code in that web framework, will I be
able to compile it for static pages (html+js) to be executed on an user browser?
Thanks in advance!
