Lazy macro loading seems to be breaking on Julia v1.9.0-rc1

[singularitti]

I am trying this in my startup.jl:

@lazy_startup using Unitful @u_str

But it does not seem to be loaded on Julia v1.9+.

Hey, I can't reproduce it.

false

m

true

OK, it seems to be happening since I have the following lines in my startup.jl:

using REPL
atreplinit() do repl
    if !isdefined(repl, :interface)
        repl.interface = REPL.setup_interface(repl)
    end
    REPL.ipython_mode!(repl)
end

This is the IPython mode that v1.9 introduced (see JuliaLang/julia#46474). It may change the environment in REPL. I tried to put these lines before using LazyStartup: @lazy_startup, but no effect.

I have met a similar issue before, maybe this link will help: KristofferC/OhMyREPL.jl#279

Thanks, I will look into it later.

I believe that the reason for the issue is due to the ipython_mode which breaks the ability to load a package and using macros provided by that package in a single input line in the REPL. See JuliaLang/julia#49041.

Please try 0.2.0 with

atreplinit() do repl
    if !isdefined(repl, :interface)
        repl.interface = REPL.setup_interface(repl)
    end
    REPL.ipython_mode!(repl)
    lazy_startup_init!()
end

Note, the lazy_startup_init! must be after the REPL.ipython_mode!.

It works for me, thank you!
