I’m sad to hear my recent bad Merrills we’re not a one-off. I know people who swear by Keen, but I can’t stand the toe box. Might have to try to get used to it for the next pair.

(1) Test coverage has dramatically improved. (2) Improved, and to some degree a matter of taste (Julia is not statically checked, so some errors can only be discovered at runtime) (3) There has been significant refactoring since 2014 to imp

Yeah, I finally got windows version to download (cut out a few times, HN overload?). The win download is an online installer, so the size makes much more sense. I didn’t check the install directory, but it took 2 minutes to retrieve on slow

I am curious about final package size on various platforms when using this project. The download bundles for the related "fman" project vary considerably -- Win: 1MB; macOS: 23MB; Ubuntu: 39MB. The last number matches my experienc

LuaJIT’s DynASM would go a long way there; might even have reusable stubs. Or slightly crazier, if 520K isn’t too big a burden: wrap the LuaJIT cffi ...from C... and embed all of LuaJIT. (by the way: thank you for libffi!)

I believe other languages could use this without Python, in principle. It is currently distributed as a Python package to provide functionality similar to the existing cffi package. The Python wheels are 18MB and statically linked -- so no

The LGPL requirement is relinkability, which implies either distributing object files for your application (rare, inconvenient), or, more commonly, linking the LGPL library as a shared object. But that shared object could be stripped down t

The other thing to keep in mind is that a similarly script-extensible Qt application carries the weight of Qt shared libraries, plus scripted wrapper shims. This can easily run 25-40 MB in Python-Qt systems, at which point 70 MB for Electro

Julia's meta-programming functionality is ideal for implementing such domain-specific languages (the popular JuMP suite is a flagship example in a different domain: https://jump.readthedocs.io/en/latest/ ). S

Parse error on my part, excuse the pedantry :) Tcl is such a weird and wonderful language, and I occasionally miss it (though I don't miss working with a GUI written in C++ wrapped around tk ).

Julia JIT compiles C calls via LLVM, so there's no libffi performance overhead (similar to LuaJIT's CFFI, though that does not use LLVM).

This is totally fair. Even the Julia creators regularly mention "stay with existing tools for now, if you are happy." Julia is an increasingly attractive option for greenfield, high-performance development, but for folks who aren&

They expose an FFTW-compatible API, but as far as I know it's an independent implementation.
