So, I was trying to use mustache.js in PG by defining a V8 function that imports it. Older versions worked fine, but in
newerversions they use a class factory and I can't figure out how to reference the mustache stuff that it creates.
ApparentlyI need to know how our V8 implementation does exports.
Here's the top of mustache.js with the class factory, and my attempted reference at the bottom (the return which gives
meundefined reference). I tried various invocations and couldn't quite get it. I ended up hacking it up to remove the
factoryand change it to explicitly declare a variable to make it work, but I'd like to avoid that if possible.
If anyone wants to try to reproduce it, replace the snipped out bits using the contents of mustache.js from
http://github.com/janl/mustache.js
CREATE OR REPLACE FUNCTION mustache(template text, view json)
RETURNS TEXT
LANGUAGE plv8
IMMUTABLE
STRICT
AS $$
(function (global, factory) {
if (typeof exports === "object" && exports) {
factory(exports); // CommonJS
} else if (typeof define === "function" && define.amd) {
define(['exports'], factory); // AMD
} else {
factory(global.Mustache = {}); // <script>
}
}(this, function (mustache) {
var Object_toString = Object.prototype.toString;
var isArray = Array.isArray || function (object) {
...
... SNIP ...
...
}));
return mustache.render(template, view);
$$;
