I don’t have any experience with other languages, and I was surprised to see “Hello World” produces this big standalone executables in Node.js. Julia is not far off then.

PackageCompiler.jl v2.1.5 + julia 1.9.0-rc2 + "Hello World!" = 408 MB = 309 MB (julia 1.9) + 99 MB (sys.dll) + 76 KB (JuliaHello.exe)

[image] woclass: PackageCompiler.jl v2.1.5 + julia 1.9.0-rc2 + "Hello World!" = 408 MB = 309 MB (julia 1.9) + 99 MB (sys.dll) + 76 KB (JuliaHello.exe) Hopefully will get there with attempts in 1.10 and more focus on this goal going onward. [image] jling: 8.4KB Yeah but we don’t get …

What language features do you want for a program that just prints “Hello, world”? If you want a small executable you can get it, but then you don’t get the language runtime features (but you don’t need them). If you want all the language runtime features you can have those but that’s a big binary.

A program could take just those parts of the runtime that it uses, and help the programmer understand where in the program they’re requiring each feature.

If we’re going to figure this out, we need to find a better example than “Hello, world”. There are a dozen languages that can do “Hello, world” better than Julia, including COBOL. IDENTIFICATION DIVISION. PROGRAM-ID. hello. PROCEDURE DIVISION. DISPLAY "Hello, world!…

Not that it matters, but in what sense is that better?

More modern, user-friendly syntax, no doubt about it.

[image] Do Garbage Collectors necessarily make code slow? Well, the executable only 17 KB, for starters. So twice the size of the executable from StaticCompiler.jl :wink:

Exactly. We can already make a smaller Hello world program than that from Julia and the program is considerably simpler.
