----------------------------------------
Summary: CoffeeScript CommonJS Functions Don't Work
Key: COUCHDB-1875
URL: https://issues.apache.org/jira/browse/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 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
