There may be a better way, but I found that running
bring up the Kotlin REPL, while in a Cygwin BASH shell using Mintty, did
not respond to keyboard input. A little research indicated the issue is
with JLine, which has some understandable difficulties reconciling running
under Cygwin with running under CMD.
The workaround I used:
$ JAVA_OPTS='-Djline.terminal=unix' kotlinc Welcome to Kotlin version 1.1.1 (JRE 1.8.0_121-b13) Type :help for help, :quit for quit >>> println("FOOBAR") println("FOOBAR") FOOBAR
Requesting JLine to use UNIX-y primitives for terminal access solved the problem. I would like to hear about other solutions.
UPDATE: Edited for clarity. And some additional reading:
