OK thanks Dave, good tip.
Unless I'm missing something though, which has been definitely known to happen,
it appears that it's not an issue with the CoffeeScript code itself. To me it
looks like the CommonJS CoffeeScript functions don't work whereas their
Javascript equivalents do.
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 example:
[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
Anyway, hopefully more pieces to the puzzle.
Thanks,
Anthony
