I have an API that takes a list of string 'fields'. I want these to map to functions on the backend, which are then called, and the data returned. I want the fns to be evaluated only when the API call is made and the result thrown away after it’s sent back to the client. For this would it be idiomatic to store a map of fields to quoted fn calls (i.e., (def foomap {:field-1 '(some-fn-1) .. :field-n '(some-fn-N)}, and then resolve the values as in (eval (:field-1 foomap))? If this is madness, what's a better way?

maybe what you need is just (def foomap {:field-1 (fn[] (some-fn-1) .. :field-n (fn [] (some-fn-N)}) and then ((:field-1 foomap))?

@andrut: Hm, yeah I think I like that better than using eval. Thanks!

can I ask clojurescript questions here?

nvm read channel description

so I've got an angular app

pure JS, no CLJS

and I want a specific "page" of the angular app

to be essentially an embedded CLJS app

is this possible? in other words can I call the initialization function of my, say, Om app

(where it targets an element by id on the page)

from plain JS?

ill direct this one @dnolen if he ever has a minute to read no worries if not though

but let me clarify that i understand that this is a weird use-case for cljs, its just that we have a monolithic enterprise angular app, and are only partway through the development wanting to try some CLJS in client-facing production

and as such it isnt feasible to rebuild entirely in CLJS

CLJS namespaces compile into google closure namespaces. So if your main CLJS namespace is my-app.core, you can access the functions that ns provides by accessing window.my_app.core

right

so if my entire Om app is behind one initialization function

where im targetting an element on teh page by id and rendering

I just call that function at my-app.core.initialize() and boom done

e.g. http://nickol.us/om-identicon/ - in the developer console you can enter om_identicon.core and it will return that NS in javascript

very cool. thanks @teslanick

So you could do my_app.core.initialize() and get what you want.

You probably want a teardown method as well.

(assuming the page falls out of scope, you want to do a (js/React.unmountComponentAtNode root-node))

Nix that, if you're using Om, you want (om.core/detach-root root-node)
