You should probably file an issue with IJulia:

Thanks for pointing me in the right direction! I will do that.

I guess IJulia is suppose to work on the notebook (ipython notebook --profile=julia) only.

If one wants Julia in a console, julia REPL is the way to go.

I say this because the issue has already been around from a long time ago.

I also think that IJulia came to be mostly because of the netbook, and it is where it is most useful, still in the IJulia page:

https://github.com/JuliaLang/IJulia.jl#running-ijulia

They advertise the command I used:

ipython console --profile julia

Along with:

ipython qtconsole --profile julia

ipython notebook --profile julia

There are many issues here,

First is that `ipython console` is not a lot used, so there is only a few bugs report.
This is mainly due to the fact that of course people use native repl most of the time.

There is the possibility to bind another key-combinaison to "force new line" without executing.
Because right now the console process (python) is lexing input at python and is the one deciding wether
to insert a new line or execute this would only be a temporary workaround until we add the possibility
to ask the kernel to do lexing and decide wether or not an input is done.

Little late on this thread, but thought I'd chip in. While I haven't had a ton of time to polish, I personally use the Sublime-IJulia frontend each day for my own julia work. Handling multiline input like this is pretty trivial and can be accomplished in Sublime by selecting multiple lines and running Cmd/Ctrl + Enter to send to IJulia, or in the repl/console itself, you can press Shift+Enter to enter a newline without evaluating. I do plan on putting some more time into this at some point (hopefully the next few weeks) to fix a few key-binding bugs and get some documentation together, but if anyone is interested in trying out the beta, I'm happy to help get things up and running/troubleshoot. (A side note is that you don't even have to have IPython installed; the only requirement is that you can successfully build/install the IJulia package in julia).

Cheers,
