Fix compatibility issue

[vavrines]

Current setup in Project.toml can trigger incompatibility in Julia 1.5. Fixed in this branch.

Thanks for the pointer. This is a tedious thing to get right in my experience (of course, I might do something wrong). I remember I played a long time to get the current version of Project.toml to compile with Julia 1.1 - 1.3. I also wanted to use the >= notation, but SpecialFunctions always plays the devil...

Here's a solution: check what versions of the required packages works for Julia 1.4 and 1.5, and then add them to Project.toml manually.

As I said -- unfortunately, I found no better way around yet.. =/

Yes, something still goes wrong in travis. I think it's related with SpecialFunctions. I'll have a look there.

Thanks a lot!

SpecialFunctions has given me a lot of headaches to get right.. Perhaps it works if you use the old entry from Project.toml for SpecialFunctions?

[vavrines]

Quite weird: I copied the old Project.toml exactly into my fork, but the travis build stills fails for julia 1.0 and 1.1...

Are you positive it's the same toml file? The problem is and remains

ERROR: LoadError: UndefVarError: loggamma not defined

which is due to SpecialFunctions... =/

should be the same since I directly ctrl c/v there..

[timueh]

This is strange indeed. I guess we should ask for help on discourse? As I said, I can't really count the hours I spent trying to fix this..

I am still on paternal leave and can't really take care of it. If you want, go ahead and post it. If you don't want to---which would of course be fine---I'll go ahead in the next weeks.

I think a reasonable solution is to take the version of the Project.toml that works for Julia >= 1.3, and stop supporting Julia 1.0 and 1.1.. It's kind of a cheap way out but unless you want to spend hours on fixing the toml that's what I suggest.. ^^

That's also exactly what I was thinking about.
SpecialFunctions made a quite big change from 0.7 to 0.10 due to some built-in functions in Julia, and now they only do test on Julia 1.4. As other dependencies update, it could get harder in the future for the compatibility. Supporting 1.3 upwards is a good idea.

[timueh]

That should be fairly straightfoward then. All I need to remember is to also compile the documentation with Julia 1.3 or above.

I hope to get this done soon.

Thanks for the input!

i released polychaos as version 0.2.3 which fixes the issues you mentioned.

once again, thanks.
