As of Julia 1.0, InteractiveUtils needs to be imported for juliaconsole envs

[tawheeler]

Several functions available in the real Julia console are no longer available in normal Julia without importing the InteractiveUtils package.
juliaconsole environments should probably have using InteractiveUtils under the hood.

[tawheeler]

I tried using \pythontexcustomc{juliacon}{using InteractiveUtils}, but that substitutes every other juliaconsole block with using InteractiveUtils, doubling the number of envs that show up :(

In other news, I expected juliaconcode to execute but not display anything, and it appears to be typesetting. (executing correctly as expected though).

For using InteractiveUtils, I'd suggest opening an issue in Weave.jl, which is being used to do the actual code execution. I may be able to figure out something in the meantime.

Currently, the juliaconsole is really a hack on top of a code environment, so no other environments work as expected. I was just reminded of that myself in the last few days...I've been adding a console environment for R, to try to get some ideas about how to redesign things to make it simpler to add console environments. I'll see if I can at least get a proper juliaconcode and \juliaconc working.

Awesome, thanks!

JunoLab/Weave.jl#151

FWIW, temporary solution is to run the code but hide it off the page:

\begin{textblock*}{\textwidth}(50cm,0cm)
    \begin{juliaconsole}
        using InteractiveUtils
    \end{juliaconsole}
\end{textblock*}

pythontexcustomcode and \pythontexcustomc with juliacon, and juliaconcode should now work as expected.

[tawheeler]

You're awesome! We're incorporating it now. Will close the issue.

Does it make sense to tag a new release at this point? This is pretty nice functionality to have in the version on CTAN.

[gpoore]

@mykelk Yes, a new release on CTAN is long overdue. There's a pull request that will add support for all Jupyter kernels, and I'm hoping to get a new release out once that is merged.
