I'm working through Closure tutorials translating them to
ClojureScript. Unfortunately, I've hit a problem where the code works
with {:optimizations :simple} but fails with {:optimizations
:advanced}.
The code is very simple. It basically is a trivial template example
with Soy (from Closure templates). Here's example/core.cljs:
(ns example.core
(:require [goog.dom :as dom]
[goog.date :as date]
[soy :as soy]
[example.templates :as tmpls]))
(defn map-to-obj [m]
(.strobj (reduce (fn [m [k v]]
(assoc m k v))
{}
(map #(vector (name %1) %2) (keys m) (vals m)))))
(defn ^:export say-hello [message]
(let [hello (dom/getElement "hello")]
(dom/setTextContent hello message)))
(defn ^:export say-hello2 [message]
(let [hello (dom/getElement "hello")
data {:greeting message
:year (. (date/Date.) (getFullYear))}]
(soy/renderElement hello tmpls/welcome (map-to-obj data))))
And the template hello.soy:
{namespace example.templates}
/**
* @param greeting
* @param year
*/
{template .welcome}
<h1 id="greeting">{$greeting}</h1>
The year is {$year}.
{/template}
The template is compiled to hello.soy.js. I pass in the path to
hello.soy.js as well as closure-templates/javascript during compile.
The HTML:
<!DOCTYPE html>
<html>
<head>
<title>Example: Hello World</title>
</head>
<body>
<div id="hello"></div>
<script src="hello-cljs.js"></script>
<script>
example.core.say_hello2("Hello World!");
</script>
</body>
</html>
With simple optimizations, this produces the expected output. With
advanced optimizations both fields of the template are undefined.
I'm probably doing something silly. Any ideas?
