Anthony Kaufman commented on COUCHDB-1875:
------------------------------------------
Yeah, I think you're right. If that's true then I should be able to include a
Javascript CommonJS function even though the rest of my functions in the design
document are CoffeeScript. I'll try that out and see if it works.
If I would have time to fix it myself, I'm going to confess my ignorance of how
to even start testing it. Would I change the code, make, and then be able to
run the couchdb server from the source directly somewhere?
> 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:
> {code:javascript}
> {
> lib: {
> simple: "exports.callback = function() { return 'Simple' }"
> },
> test: {
> map: "function(doc) { emit(require('views/lib/simple').callback(), doc) }"
> }
> }
> {code}
> As expected, "Simple" is emitted for the key of every document.
> Now the equivalent CoffeeScript code:
> {code:javascript}
> {
> lib: {
> simple: "exports.callback = () -> 'Simple'"
> },
> test: {
> map: "(doc) -> emit(require('views/lib/simple').callback(), doc)"
> }
> }
> {code}
> 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
