Keywords sent over eventbus and sockjs bridge lose namespace

[Jared314]

My server process responds to an event on the Vert.x eventbus, sent using js client library and sockjs bridge, with a hash-map whose keys are namespaced keywords.

{ :workorder/company "Company Name 1" }

When I access the results, in the reply function on the js client, the keywords arrive with the namespace set to null.

cljs.core.Keyword {ns: null, name: "company", fqn: "company", _hash: null, …}

The namespace is also lost on keywords sent from the js client.

We lose the namespace for symbols when we encode to json for the eventbus. If you need a higher-fidelity format, I recommend encoding the data as edn or transit to a string before sending it, then decoding it on the other side. I don't think it would be difficult to write a few wrapper functions to handle that for you. Will that solve your use-case?

[Jared314]

Encoding it manually will work as a short-term workaround.

I can understand stripping symbol namespaces, but a keyword namespace, because of its use in preventing key collisions, feels like something that should be preserved.

I took a closer look at this, and I think you're right - we should write namespaced keywords out to json as "workorder/company". The keyword function in older versions of cljs wouldn't restore the namespace, but it looks like recent cljs versions do (or at least the latest (0.0-2322) does). I'll try to get this implemented in the next couple of days and get a release out.

Implemented in 96eaa98. I've released 1.0.4-SNAPSHOT - can you give that a try and see if it works for you? You'll need to update conf/langs.properties in your vert.x install, but won't need to recompile your clojurescript.

That fixed it for me. Thank you.

[tobias]

Great, thanks for the feedback. I'll try to get a release out early next week.

This was released as part of 1.0.4.
