Re: Is there a way to stop a long running expression in the REPL

2015-02-23 Thread Erik Price 
Vim Fireplace  supports Ctrl-c
without killing its REPL host. Highly recommended if you are a Vim user.

Using Lein 2's REPL, Ctrl-C doesn't cancel the REPL itself.

Re: Is there a way to stop a long running expression in the REPL

2015-02-21 Thread Lee Spector 

In case anybody is developing tools for this kind of thing, one of the things I 
most miss from Common Lisp is the ability to interrupt a running expression AND 
see the values of locals at the point of interruption. Fantastically useful for 
debugging. As far as I know there's no environment that lets you do this for 
Clojure. Seeing locals at the context of an exception (for each stack frame) is 
also fantastically useful and at the top of my wish list for the ecosystem... 
and while I've heard tell that there's a way to do this (Ritz?) if you run 
within emacs, I've never actually seen this in action and would love it if 
there was a more broadly accessible way to do this.

It depends on what REPL/IDE you are using. In Counterclockwise there's an 
icon on the REPL pane's upper right with a red box near a gear, third from 
the left, which interrupts the currently running expression. Some other 
REPL environments provide similar functionality, as other people have noted 
in this thread, while others unfortunately don't provide a way short of 
restarting the REPL (and losing anything you've def'd or defn'd at the REPL 
in the process -- it's a good idea to keep a scratch file in Notepad or 
somewhere and paste things there that don't belong in your source code but 
which are convenient to run from time to time in the REPL, such as ad hoc 
tests or convenience functions and defs for during development).

​I am using:
rlwrap java -cp "${CP}" clojure.main --init "${CLOJURE_INIT}" --repl

But maybe it is time to switch. ;-)​

Which repl are you using? In lein repl, this does not happen to me, it
just terminates the expression.

Is there a way to stop a long running expression in the REPL

2015-02-21 Thread Cecil Westerhof 
Sometimes I execute something that takes to long. With -C I can
cancel it, but this also cancels the REPL itself. Is there a way to
terminate the running command without terminating the running REPL?
