"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

Version 1.11.0-rc3 and nightly,
@numbermaniac , @osimonn

This isn’t only an issue with OhMyREPL. I have the same with InteractiveCodeSearch.

[cena]

Error persists with 1.11.1 (2024-10-16), works with @jlapeyre 's using Pkg: Pkg addition to startup.jl.

[cena]

Just another data point:

Warning with 1.12-DEV.1680:

┌ Warning: error while importing OhMyREPL
│   e =
│    ArgumentError: Package OhMyREPL not found in current path.
│    - Run `import Pkg; Pkg.add("OhMyREPL")` to install the OhMyREPL package.
└ @ Main ~/.julia/config/startup.jl:6

---

Adding import Pkg; Pkg.add("OhMyREPL") to startup.jl (and removing 'using Pkg: Pkg') works on both this version and 1.11.1.

[jlapeyre]

My recollection is that I found OhMyREPL was using something in an extension in Pkg. Maybe it was moved out of Pkg and into an extension, and any package that depended on that something being there would break.

[jlapeyre]

Adding import Pkg; Pkg.add("OhMyREPL") to startup.jl (and removing 'using Pkg: Pkg') works on both this version and 1.11.1.

Looks like you might be confused about the message. If you started 1.12 for the first time, OhMyREPL would not be in your default environment. Doing import Pkg; Pkg.add("OhMyREPL") just once is enough to take care of it. This doesn't belong in your startup.jl.

For practical purposes, using Pkg: Pkg and import Pkg are doing the same thing. After having installed OhMyREPL (once), either one will do.

Ah! @jlapeyre - thank you for your correction of this hapless newbie - the kindness + education is much appreciated. :)
