Description

I get the following error when I run "boot repl" [WARNING] No nREPL middleware descriptor in metadata of boot.repl$disable_exception_colors@4c415a68, see clojure.tools.middleware/set-descriptor! nREPL server started on port 55825 on host 127.0.0.1 - nrepl://127.0.0.1:55825 REPL-y 0.3.7, nREPL 0.2.12 Clojure 1.8.0 Java HotSpot(TM) 64-Bit Server VM 1.8.0_60-b27

Why is this happening? Does it cause any problems? Is there a way to fix it? Thanks for your help.

It is not Windows-specific. I see this on Mac when starting a REPL in Atom/ProtoREPL as well as from the command line. My comment on Slack:

That warning appears for Boot REPL on all platforms I believe wherever colorization is disabled. The solution would be for boot.repl/disable-exception-colors to have metadata of ^{:clojure.tools.middleware/descriptor {}} I think.

Reproducible by disabling colorization, as @seancorfield mentioned above:

boot -C repl

Found this while googling, apparently pretty had the same problem and this is how they fixed it: https://github.com/AvisoNovate/pretty/pull/29
