Natal only reloads core namespace

[scttnlsn]

Is this by design? Ideally I'd like to be able to make a change in any namespace and have it hot reloaded in my simulator. Is that possible?

FWIW, it is modeled after this blog post which exhibits that limitation. http://blog.fikesfarm.com/posts/2015-05-30-poor-mans-figwheel-for-ambly.html

OK, thanks.

At this point I'm not sure about the best approach for developing a multi-namespace app w/ Natal + Ambly. Since Cmd-R reloads the JavaScript it seems my only option at the moment is to re-launch the app on every change (which is far too slow to be effective). I'll need to explore Ambly further to better understand what's possible in terms of reloading. Any advice/pointers you have would be great.

You can always use the REPL and issue a (require 'foo.core :reload) to reload a namespace. That will cause Om and React to re-render.

Interestingly, I tried a simple experiment where the main namespace simply delegates to another namespace to get, say, a UI string to put in the button in the sample app that gets automatically generated. If I then do (require 'future-app.core :reload-all) (the main namespace), it doesn't seem to reload my additional namespace. (I have to manually require it first.) I'm wondering if this :reload-all behavior is an Ambly issue, or a ClojureScript issue, or a misunderstanding on my part.

@mfikes Yeah, I'm experiencing the same issue.

I'm also having trouble getting the Ambly REPL working through Emacs. Works great in a terminal but I have to manually evaluate (require 'future-app.core :reload-all). I'd love to be able to reload the namespace via Emacs key bindings.

After running cider-jack-in I evaluate:

(require
  '[cljs.repl :as repl]
  '[ambly.core :as ambly])

(repl/repl (ambly/repl-env))

Which successfully starts the CLJS REPL. Trying to evaluate any expressions after that just hangs.

See the :choose-first-discovered true stuff in https://github.com/omcljs/ambly/wiki/REPL-in-Cursive. I think it applies to your Emacs case. If that doesn't work, perhaps Piggyback is also needed as described there.

@scttnlsn For :reload-all, I spun off mfikes/ambly#113

@mfikes Thanks, working well in Emacs using Piggieback. Still need to reload both the changed namespace and core before I see the changes loaded in the app. I'll follow along in mfikes/ambly#113

doesnt address the core namespace issue, but heres the setup i have to trigger a reload on save from an cider piggiebacked repl
