Error UndefVarError: @compiler_options not defined

[CourtA96]

The @compiler_options macro is no longer defined in Base.Experimental, which causes an UndefValError when precompiling MLStyle. I forked the package and changed every line that read:

if isdefined(Base, :Experimental)
    @eval Base.Experimental.@compiler_options optimize=0 compile=min infer=no
end

to

if isdefined(Base.Experimental, :compiler_options)
    @eval Base.Experimental.@compiler_options optimize=0 compile=min infer=no
end

and that seemed to fix the issue for me. I don't know if this fix impacts the functioning of the package though.

Your fix seems correct.
I don't have an idea if Base.Experimental is always available since Julia 1.0?
Anyway thanks for your notification! I will investigate this soon, and PRs are welcome!

Hello. I've just started working on this. I found that in the master branch of julia repo, stdlibs are still referencing this under @compiler_options under Base.Experimental. Could you please provide more information about your working environment?

[CourtA96]

I was using the default environment for Julia 1.3.1. The older versions of Julia don't have @compiler_options defined in Base.Experimental. When I raised this issue, I hadn't realized that I had reverted to an older version, so I assumed @compiler_options must have been deleted. Now that I'm back to Julia 1.6.1 the error doesn't occur.

I'm sorry for the confusion!

I am using GeneralizedGenerated.jl in my package and GeneralizedGenerated.jl depends on MLStyle.jl. My package stopped working under julia-1.3.1 do to this issue. Any hope of getting this issue resolved?

[thautwarm]

@hofmannmartin can you try the latest version of MLStyle?

[hofmannmartin]

works like a charm with the latest Version. Thank you.

@CourtA96 I think 0.4.13 works for Julia 1.0-1.8, could you help verify this? I want to close this issue.

[CourtA96]

Yes, it's working for me now in Julia 1.3.1. Thanks!
