"UndefRefError: access to undefined reference" in 1.11 beta

[numbermaniac]

Following the installation guide, I have this in my startup.jl file:

atreplinit() do repl
    try
        @eval using OhMyREPL
    catch e
        @warn "error while importing OhMyREPL" e
    end
end

In Julia 1.11 beta 1, I see the following message when starting a repl now:

┌ Warning: error while importing OhMyREPL
│   e =
│    InitError: UndefRefError: access to undefined reference
│    during initialization of module REPLExt
└ @ Main ~/.julia/config/startup.jl:5

I didn't see this message in 1.10, so I'm guessing it's something to do with 1.11 specifically. The error message means that none of the syntax highlighting works.

Interestingly if I do using OhMyREPL after the repl has started up, then there are no import errors and all syntax highlighting works. So it seems like something is broken here.

I tried slimming down my startup.jl file to just using OhMyREPL but I get the following error when entering Pkg mode and try to add a package:

I am not sure if this error is related to this issue.
Here is my setup:

Another thing I noticed is that, if I do @eval using OhMyREPL a second time to make it work (as mentioned in my first comment), it breaks the ability to hit ] to enter the Pkg REPL. Instead, it just types a ] into the Julia REPL now.

The bug is also present in 1.11.0-rc1.

[huangyxi]

Take a try:

# ~/.julia/config/juliaup.jl
if isinteractive()
	try
		using OhMyREPL
	catch
	end
end

[KristofferC]

I think this has to do with Pkg moving out of the sysimage, this part of the code should maybe move to an extension.

[jlapeyre]

I find no error and that OhMyREPL works properly if I load Pkg first. For example:

using Pkg: Pkg
atreplinit() do repl
    try
        @eval using OhMyREPL
    catch e
        @warn "error while importing OhMyREPL" e
    end
end
