Subject [jira] [Created] (COUCHDB-1875) CoffeeScript CommonJS Functions Don't Work
Date Tue, 20 Aug 2013 22:05:51 GMT
Anthony Kaufman created COUCHDB-1875:

             Summary: CoffeeScript CommonJS Functions Don't Work
                 Key: COUCHDB-1875
             Project: CouchDB
          Issue Type: Bug
          Components: JavaScript View Server
            Reporter: Anthony Kaufman

Reusable CommonJS functions written in CoffeeScript raise exceptions when referenced from
map functions.

Consider the following Javascript code:
	lib: {
		simple: "exports.callback = function() { return 'Simple' }"
	test: {
		map: "function(doc) { emit(require('views/lib/simple').callback(), doc) }"

As expected, "Simple" is emitted for the key of every document.

Now the equivalent CoffeeScript code:
	lib: {
		simple: "exports.callback = () -> 'Simple'"
	test: {
		map: "(doc) -> emit(require('views/lib/simple').callback(), doc)"

The view returns no results and an error for every document is printed to the log file. For
[info] [<0.7270.11>] OS Process #Port<0.96999> Log :: function raised exception
(new TypeError("require(\"views/lib/simple\").callback is not a function", "undefined", 3))
with doc._id 8117
