I believe the "problem" in this case is that typically, one types exit to exit a shell (bash, ruby, python [warns you that this doesn't work]). This is quite convenient for newcomers (and no other shell that I'm aware of, in windows, requires a ctrl+d or ctrl+z to exit).

Re: easier exit
Yeah, you're right. I was thinking of what happens when you fall off the end of main. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Falling off the end of main won't and closing all GUI windows won't, but System/exit is supposed to kill the VM reliably. In particular, when I did this: user=> (def q (agent [])) #'user/q user=> (send q conj 3) # user=> (System/exit 0) Repl is disconnected and Task Manager showed the Java process disappearing completely, even though (for some odd reason) agent threads are non-daemon (which is why the JVM will linger after a GUI closes if you don't call shutdown-agents after using agents). -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: easier exit
If you are running any non-daemon threads, even System.exit won't cause the JVM to shut down. Whereas as Michael Wood pointed out, there are various control sequences that do the trick reliably. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Hi Roger, Thanks for asking--it is always good to start on the mailing list before going to the trouble of making a patch. A REPL exit patch would not be accepted, for the following reasons: (1) The problem, and its solution, are far from clear and compelling. Python's approach to this is not universally hailed as a good one. (2) Language features sit at the bottom of the world, and gain momentum if they solve problems nobody else can solve at a higher level. REPL interaction niceties can be solved at a higher level, and the fact that different people do it different ways is good anecdotal evidence that there need not be a one-size-fits-all solution in the language. (3) The default response for good new features is, and has to be, "No, thanks." Clojure would triple in size otherwise. > Also is there any way to contribute patches to the clojure website > itself? (maybe put it up on github too?) Instructions on the patch process are at http://dev.clojure.org/display/design/JIRA+workflow. Issues waiting for patches are at http://dev.clojure.org/jira/secure/IssueNavigator.jspa?mode=hide&requestId=1.

Re: easier exit
Using jline you can exit with ctrl-d. This is from the clojure web site in Getting Started: The REPL has very rudimentary editing. For a better experience, try running it via the JLine ConsoleRunner: java -cp jline-0_9_5.jar:clojure.jar jline.ConsoleRunner clojure.main On Feb 24, 4:38 pm, rogerdpack wrote: > Hello all.

easier exit
Hello all. A bit new to clojure here. Anyway I found it a bit difficult to exit from a REPL. Would a patch to make it give instructions (like Python's C:\>c:\installs\Python26\python.exe >>> exit Use exit() or Ctrl-Z plus Return to exit >>> ) like that have a chance to be accepted? Also is there any way to contribute patches to the clojure website itself? (maybe put it up on github too?)
