Error using Array span field in Julia 1.11.1

[danielmatz]

I was just trying Julia 1.11.1 with snail, but it seems that JuliaSnail.jl references some Array internals, which have changed?

julia> JuliaSnail.start(10011) ; # please wait, time-to-first-plot...
MethodError(convert, (Tokenize.Lexers.Lexer{Base.GenericIOBuffer{Vector{UInt8}}, Tokenize.Tokens.RawToken}, Tokenize.Lexers.Lexer{IOBuffer, Tokenize.Tokens.RawToken} at position: 0), 0x0000000000006885)

That’s looks like a return value from CSTParser. Can you check the version you have? If it’s not 3.4.2, can you try to downgrade?

I had this error with julia 1.11.1, then upgraded julia-snail to 20240812.840 and it went away.

I can reproduce the problem with obsolete julia-snail 20231026.2200 .

[danielmatz]

My Manifest.toml had CSTParser 3.3.6, even though the Project.toml had a compat bound ~3.4.2. I manually ran pkg> update and it seems to work now. This is with the latest master.

I guess I thought that Snail would update its environment itself if needed. Does it not do that?

I didn't dig into it too much, but here's my experience. I did not manually update any environments and it worked. When updating julia-snail, I see Messages that new julia packages are being copied. I see that a new environment with new files has been created in my /tmp files.
