auto-completion is broken in cider after moving to a new namepsace on a CLJS REPL.

if you encounter issues - it’s best to report them on github

ideally, with some repro steps

@bozhidar: I already reported an issue on github. Check it out

Thanks

Do you get a stacktrace dumped to the REPL?

@cichli: I have https://github.com/clojure-emacs/cider/issues/1489#issuecomment-167415309 instead

Thanks, that's enough for me to replicate - I'll take a look this evening

I think the first two examples are expected; cljs.repl is only automatically required in the cljs.user namespace

So, what is wrong?

But the latter sounds like either a bug in the CLJS autocompletion code, or possibly a bug in the CLJS compiler itself (can you successfully use any of the macros in cljs.repl that you didn't specifically impot?)

Oh, I see, you're still seeing print-doc in the completions for the first two cases

@cichli: I can execute (cljs.repl/source cljs.repl/doc) after executing (ns hello-world.test (:use-macros [cljs.repl :only [doc]])).

Macros are only not available for auto-completion, but they are always there.

Even after (ns something.core), cljs.repl/doc, cljs.repl/source, etc are available for invocation. But, they are not available for auto-completion.

Gotcha, thanks

This issue might be specific to cljs.repl, so we might just have to special-case that. I'll see if the issue occurs for other macro namespaces

Thanks for the detailed report

I haven't tested other namespaces, yet. I think making it a special-case would be fragile since clojurescript can change later.

@cichli

If everything in cljs.repl is always available in all namespaces in CLJS REPLs, that's not too likely to change - it's hard not to special-case as we rely on data from the CLJS compiler to populate the completions, which doesn't have any knowledge of REPL-specific quirks like that namespace always being available

I wouldn't actually hardcode everything that's in cljs.repl into the completions - I'd still introspect that NS and get all the public vars + macros

cljs.core doesn't hide anything.

Ouch, cljs.pprint is unavailable for auto-completion after moving to a new namespace. What is this?

Why do namespaces hide completely or expose themselves partially after moving to a new namespace?

@cichli

At this point, I surmise clojurescript exposes only required namespaces reliably.

cljs.core is always available for invocation and auto-completion

cljs.repl/print-doc is always available for auto-completion, and the rest of cljs.repl is available for only invocation when it's not required.

@cichli: If I launch figwheel on lein repl, cljs.repl is somehow available for auto-completion after invoking (ns).

Somehow, figwheel on lein repl fails to auto-complete my namespaces.

The auto-completion is like a roller coaster for now.

Completion is contextual depending on the namespace because the following is not a valid ClojureScript program:

(ns foo)

(cljs.pprint/pprint "bar")

> The auto-completion is like a roller coaster for now. What's that supposed to mean?

I couldn't have been able to predict what would be available for auto-completion so far. So, my mood fluctuated like a roller coaster.
