Error when completing string starting with a "/" character. #6

Closed hrathod closed 12 years ago

hrathod commented 12 years ago

An exception is thrown in the REPL, when completing a string that begins with a "/" character.

; nREPL 0.1.3                                                                                   
user> (println "/t")

results in the following exception after waiting for auto-completion pop-up:

Thanks - fixed! Like in nrepl.el itself, the solution is to not allow completion when the point is inside a string.
