documentation shouldn't err or ""

[bbatsov]

cider.nrepl.middleware.complete> (jvm-complete/documentation "")
StringIndexOutOfBoundsException String index out of range: 0  java.lang.String.charAt (String.java:646)

Ideally this should return "" (what happens with unknown symbols).

Agreed. Although I would expect CIDER middleware to catch all possible underlying exceptions and send the trace via its internal pipes.

[bbatsov]

That was just fixed in the middleware.

[alexander-yakushev]

OK. So should I still put a try block around that code? In that case I would just silently swallow exceptions which would make debugging more difficult.

Another thing to do is just to handle empty input to documentation.

[bbatsov]

I'd handle empty empty input. Seems like the reasonable thing to do.

Fixed in e6040df.
