zeromq/IPython notebook integration.

[Carreau]

Hi guys,

As seen in #1330 we discussed integrating Julia in IPython notebook.

In ipython/ipython#2643 I was able to do the basics for ruby, based on an already existing work.

So i'm trying to do it in Julia.

Right now, I'm hitting the issue that I can't figure out how to use the zmq module wich tells me :

$ ./julia

julia> require("ui/zeromq/zmq")
error in method definition: function Base.convert must be explicitly imported to be extended

I googled around, read the doc and grep'ed in the source tree, but so far no luck.

I hope it will only be second for you to solve it. I already apologize, this is certainly a newbies question as this is my first julia program.

Thanks !

Great to have you trying this! cc: @aviks, @timholy for ZMQ expertise.

[timholy]

I think this is a casualty of recent changes to modules; I haven't used it myself in a few weeks. @aviks has just packaged this, perhaps he's fixed it already? I think the plan is for the code in ui/ to go away.

[aviks]

Yes, ui/zeromq/zmq has been broken since the Module/method import changes. The packaged version is correct.

@Carreau, try the packaged version from https://github.com/aviks/ZMQ.jl

essentially, in a julia REPL,

require("pkg")
Pkg.init()
Pkg.add("ZMQ")

require("ZMQ")

Let me know if you have any problems. It'll be great to have iPython notebook integration

[Carreau]

Thanks for the answer !

But that's for sure because my work blocks git protocol.. (any way to ask it to do it with https ?)

Otherwise i'll do it from home and keep you informed...

I guess I'll be bothering you for the next few weeks :-)

Thanks.

I need to implement an easy way of switching all our git protocol URLs at once. Sorry about the hassle. I really wish that GitHub would implement access controls for their SSH protocol so that everyone could just use ssh:// urls for everything.

I really wish that GitHub would implement access controls for their SSH protocol so that everyone could just use ssh:// urls for everything.

Github guy are competent, and they already did a lot of stuff with the ability to push over https (as some firewall block port 22... hum) but ssh would be nice too.

I really wish the IT guy wouldn't respond "have you tried start menu> reboot" when you just told them just made kernel upgrade and that with ssh tunnel it does works.
and
"we don't know why it is not booting" after bringing a computer 2 day earlier and tell "can you reinstall the MFT is corrupted". ( and BTW they couldn't because they didn't had any floppy disk to put the raid driver on it...sight)

[Carreau]

require("pkg")
Pkg.init()
Pkg.add("ZMQ")

require("ZMQ")

Works !
Great ! I'll see what I can do with that !

[StefanKarpinski]

Excellent. (It's nice when someone tells me this works since otherwise all I see is breakage.)

Further discussion on zeromq/ipython integration can continue in #1330. Closing this since the zmq issue seems like it is resolved.
