Luxor in notebook on Julia 0.6 = world error

[KristofferC]

Tried to use Luxor but something seems a bit odd:

Not sure if the problem is here but thought I would post an issue anyway...

Thanks, Kris, looks strangely familiar... :). I wonder whether this is just general v0.6 flakiness, or something else. I've been struggling to get some other basic packages working too - I've been getting QuartzIO errors, for example. But this one seems OK:

(Note that you probably want to choose a non-white color for text.)

[KristofferC]

Okay, maybe it is something strange with my setup then. Anyway, it seems that the problem is not here. Sorry for noise :)

[cormullion]

No problem - nice that someone's trying to use it.😀

This hasn't gone away like I thought it might. Julia v0.6 should be stable by now. So it might be fixable here.

I tried using Luxor in Juliabox with a 0.6 kernel. At first I had problems (like infinite freeze), but then I ran Pkg.add("ImageMagick") and the following works:

using Luxor
@png begin
        fontsize(50)
        circle(O, 150, :stroke)
        text("hello world", halign=:center, valign=:middle)
     end

But if I use @svg instead of @png the text is unreadable.

Should ImageMagick be in REQUIRE?

@ggggggggg I've not tested Luxor on JuliaBox (my experiences with JBox haven't been encouraging†) but I'll have another look tomorrow.

† INFO: Upgrading Luxor: v0.8.6 => v0.9.1
GitError(Code:ERROR, Class:OS, cannot extend packfile '/home/juser/.julia/v0.6/Luxor/.git/objects/pack/pack_git2_bHHsuZ': No space left on device)

I've never installed ImageMagick locally, though...

I finally managed to get JuliaBox working again, but to me it's the SVG that works OK, and the PNG format that might need some help from ImageMagick on Linux. (ImageMagick isn't needed on macOS.)

I'll find out how to add conditional dependencies (require ImageMagick only on Linux...).

More about world age errors on this Discourse post. I've no idea how to stop the error appearing though...

JuliaLang/IJulia.jl#609 , but now presumed to be problem in FileIO.jl (JuliaIO/FileIO.jl#142). Hopefully fixed by commit d333473 (release v0.10.2).
