[BUG] ImageIO not automatically flagged as dependency for Javis.jl
New Julia and Javis user here. Found my way here after exploring Luxor.jl. Thx for this package as animation is such an effective tool for conveying ideas.
Just wanted to report a very small error I received following Tutorial 1 instructions. When I ran render(...), I get
Fatal error:
ERROR: LoadError: ArgumentError: Package ImageIO not found in current path:
- Run `import Pkg; Pkg.add("ImageIO")` to install the ImageIO package.
The fix for me was easy, just add the ImageIO package. But if there a simple fix in the Javis code that flags the ImageIO package as a dependency, then future users may be saved this extra step and small hiccup when using Javis for the first time.
Hi Adam,
thanks for joining the community. We actually have ImageIO as a dependency but we might need to do something else there. I'll try to test this on my end. Will let you know when I found out how to solve it.
Unfortunately I'm not able to reproduce this issue. I tried it in a new environment, in the latest Julia version where I don't have ImageIO installed. Do you mind giving me some more information? What is the output of:
] status Javis
What is the output of
versioninfo()
Thanks in advance!
Wow. That is fast service. My Julia install is very new and I do not have many packages installed.
Here is ] status Javis:
Status `C:\Users\ajf\.julia\environments\v1.5\Project.toml`
[78b212ba] Javis v0.4.0
and here is versioninfo()
versioninfo()
Julia Version 1.5.3
Commit 788b2c77c1 (2020-11-09 13:37 UTC)
If it makes a difference, the only deviation I had from the tutorial was I added a using Luxor command after using Javis.
I still have my terminal open and can go back through my history. When I installed Javis, it looks like ImageIO gets installed. Here is the relevant section of my REPL output:

All errors:
===========================================
ArgumentError: Package ImageIO not found in current path:

Oh okay I would have expected other problems when you use using Luxor and using Javis at the same time.
Javis does export the same functions as Luxor for you so it might mess some things up.
Do you mind double checking with uninstalling ImageIO and maybe even Javis so starting from the previous state without the using Luxor to check whether the error still persists?
I uninstalled ImageIO and Javis. Reinstalled only Javis. Left out the using Luxor and no problem - it works fine. I then added the using Luxor back in and the problem resurfaced. So this using Luxor is problematic.
So is Javis a superset of Luxor and they should not be loaded simultaneously? Or, is there some coding tweaks that should be done to have them play nicer together?
Thanks for warm welcome to the community and for all the help :-)
That's great to hear. We might want to state that in the documentation as well then so I'll leave the issue open for now.
Yes Javis is a superpackage of Luxor if that makes sense. Basically for everything you can do with Javis you need Luxor and we found it a hassle to always include both of them. Therefore we reexport all the functions provided by Luxor ourselves and for some of them we actually override their method to enhance Javis itself. As an example for animating text fields we overwrote the text function to hijack it and get more information that is needed for animating it which would be available for us when one would call Luxor directly if that makes sense.
If you want to follow some Javis updates feel free to join us in the Julialang zulip as we have a Javis stream there.
I am a little skeptical of the superpackage approach. Here is why.
My goal as a user of these packages is to make images and animations to convey ideas ... these images and animations would often be in the same notebook or script. Hence, to be a superpackage, everything I want to do in Luxor should be readily available by using Javis. So I tested this concept and got two errors on the first two things I tried:
Error1 using setline():

My thinking is that inter-operability of the two packages is more than a documentation isssue ... rather, it should be a feature request. Wouldn't you agree or am I missing something that might be obvious to more experienced Julia users?
Thx again for the package, I think it is really cool.
I think it's a drawback yes but I think that the other way around would be even harder as we would still need to have the same functionality. I'm not sure whether there is a good way for both of these different workflows. I either have a one frame gif or write the the frames to a folder and then display that or load Luxor in a different file. The latter might be harder to work with in a notebook though. Do you know a workaround for it @TheCedarPrince ?
Hey @Wikunia and @flyaflya - I was actually able to reproduce this error on a fresh installation of Julia (Julia 1.6.0 rc3) and when I tried to install Javis. For me, the error manifested when I was installing and running the Javis test suite for #303. I believe there may be a compatibility issue. Will continue digging into this right now.
