IllegalStateException Can't change/establish root binding of: *e with set

[ivan]

I'm using the standalone REPL with

java -Dfile.encoding=UTF-8 -cp "$(lein classpath)" reply.ReplyMain --standalone

and when I call something that throws an exception, the REPL quits:

# ./repl

Bye for now!

This happens with Clojure 1.4.0, 1.5.1, and 1.6.0.

re: "You can use the --standalone flag to rule out any nREPL-related questions, but I'm not aware of anyone using --standalone for other purposes. Please let me know if you are!"

I'm using --standalone because I don't want an nREPL listener for security reasons (especially because I have one project that requires being root.) I've documented my usage at https://github.com/ludios/py2clj-cheatsheet#start-a-repl-without-creating-a-local-security-hole

Yuck, sorry about that.

[trptcolin]

I'd done a pretty major overhaul of the standalone mode recently to fix some issues, so looks like I missed this then.

That was quick, thanks! I was about to send a pull request :-)

[mrrodriguez]

Any thoughts on when these changes will be released to clojars?

[trptcolin]

They should already be up, as of last night, as 0.3.2.

[mrrodriguez]

That's great. Thanks for the quick feedback and turnaround time!
