auto-completion breaks after moving to a new namespace on a CLJS REPL.

[crocket]

After launching a CLJS REPL, auto-completion works well.
But, after moving to a new namespace with such a command as (ns something.core), auto-completion breaks for many namespaces.

[bbatsov]

Are we talking about built-in auto-completion or some third-party package?

[crocket]

What do you mean by third-party package? You can use https://github.com/crocket/nrepl-figwheel-node-template to reproduce the issue.

Execute my template, and type

(doc doc) ENTER
(ns <<project-name>>.core) ENTER
(cljs.repl/ TAB

I should be able to see cljs.repl/doc and so on, but I only see cljs.repl/print-doc.

[bbatsov]

Third-party completion package - auto-complete-mode, company-mode, etc

[crocket]

Nope, I reproduced the issue on nrepl-figwheel-node-template without any third party auto-completion package.

@cichli Can you take a look at this, please?

[crocket]

According to my test,

• After pressing C-c M-n in a cljs file, only cljs.repl/print-doc is displayed in auto-completion of cljs.repl/.
• After executing (ns something.core), only cljs.repl/print-doc is displayed in auto-completion of cljs.repl/.
• After executing (ns something.core (:use-macros [cljs.repl :only [doc]])), cljs.repl/ TAB displays the full content of its namespace.

Including conversation from Slack for more context:

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

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

crocket [2:09 PM] 
So, what is wrong?

cichli [2:09 PM] 
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?)

​[2:10] 
Oh, I see, you're still seeing `print-doc` in the completions for the first two cases

crocket [2:11 PM] 
@cichli: I can execute `(cljs.repl/source cljs.repl/doc)` after executing `(ns hello-world.test (:use-macros [cljs.repl :only [doc]]))`.

​[2:11] 
Macros are only not available for auto-completion, but they are always there.

​[2:12] 
Even after `(ns something.core)`, `cljs.repl/doc`, `cljs.repl/source`, etc are available for invocation. But, they are not available for auto-completion.(edited)

cichli [2:13 PM] 
Gotcha, thanks

​[2:13] 
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

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contribution and understanding!

@arichiardi Can you look into this?

[vemv]

Probably this hasn't been the case for a long while.
