is there a way to hand in several lines of Javascript to Monger?

[lawrenc...@gmail.com]

I often have to generate reports -- pulling data out of Mongo, and then adding it up somehow. When I am at the terminal, I sometimes start the mongo shell and generate a report by writing serval lines of Javascript: a find() query, and then maybe a loop that goes over the results and calculates something, perhaps adding and dividing something. 

Is there  a way I can hand in several lines of Javascript code to Monger, with Monger passing it along to Mongo and getting a calculated result?

The same way you'd pass a JS function with just one line.

Clojure supports multi-line strings:

user> (def s "line one

              line two

              line three")

#'user/s

user> s

"line one\n              line two\n              line three"

Finally, you can use resource files (which is highly recommended). See clojurewerkz.support.js/load-resource

in this example:

In order to do the same thing, I used Scriptjure
(https://github.com/arohner/scriptjure) to generate JS code from
Clojure code. This was kind of insano and I recommend it only if you
are nuts and/or have to turn a Clojure data structure into a
map/reduce command for MongoDB.
