@terasakisatoshi
Is it possible to wrap and release sjulia and juliar as Julia apps?

22

You mean cargo install --path subset_julia_vm --features repl ?

Kind of.

I think it is possible to register it as a Julia package/app so we don’t need to install and compile it via Rust.

EDIT:

Like:

pkg> app add sjulia

Trying out the AOT compiler:

This is a tad faster than vectorized Python and R but still slower than Julia.

@terasakisatoshi note that my example script did not transpile to Rust correctly so I had to manually edit the emitted output.rs file.

Main issues with the code:

  • It ignored the time macro (perhaps this on purpose?) so I added equivalent code manually
  • It emitted an empty pub fn main() so I had to manually add loops and calls to test()

Also, should rand be added to cargo.toml? I added --extern rand to the build command as a workaround to get random numbers working.

But aside from these issues, pretty amazing to see things working.

I’ve released v0.9.5 GitHub - AtelierArith/julia-vm-oss: Let's run Julia everywhere from mobile to web. · GitHub

Compared to the old sjulia, it can probably do a lot more now, and I think it runs much faster too. If you get a chance, I’d love for you to give it a try.

It’s been a while so I forgot how to use it.

But I don’t think it expects Windows:

PS C:\projects\julia-vm-oss> ./target/release/juliars.exe --minimal-prelude examples/dummy_timing.jl --emit-binary target/dummy    
error: missing escaped value, expected `b`, `e`, `f`, `n`, `r`, `\`, `"`, `x`, `u`, `U`

sjulia has this issue - not sure if it’s a configuration issue on my end:

julia> 1 + 1                                                                      
ERROR: Load error: module 'InteractiveUtils' not found in LOAD_PATH
28

That’s wired let me investigate the issue including Windows one.

I could reproduce the error you reported. Thank you. This is going to take a long time.

Maybe solved.
