Go is not an easy language

• Nim

  346 16,060 9.9 Nim

  Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

  

If you think of Cython as a "new but related" language rather than just a Py compiler then you can sprinkle enough C-like `cdef` code into your Cython so that, when compiled, your code can run much faster than Go..as fast as any C, really.

That said Nim [1] provides nicer metaprogramming features than Cython and very nice overall ergonomics..I think more ergonomic than Python with, e.g. UFCS. Nim has almost all the safety/speed of Rust with better ergonomics than Python. What is not to love?

https://github.com/golang/go/wiki/SliceTricks I was reading through this, which was referenced from the article. This just seems insane. None of any of that seems intuitive.

It won't be ready for production use for a while, but https://github.com/python/mypy/tree/master/mypyc is being worked on.

If you’re ok with s/python/ruby Crystal is great, LLVM compiled and has a couple of cool web frameworks coming up.

  Discontinued A collection of useful middleware for Go HTTP services & web applications 🛃

  

Study the generic reader/writer implementations in the io module. (On my system, those sources are in /usr/lib/go/src/io.) The io.Reader and io.Writer interfaces are very simple, but very powerful because of how they allow composition. A shell pipeline like `cat somefile.dat | base64 -d | gzip -d | jq .` can be quite directly translated into chained io.Readers and io.Writers.

Another example of this is how HTTP middlewares chain together, see for example all the middlewares in https://github.com/gorilla/handlers. All of these exhibit one particular quality of idiomatic Go code: a preference for composition over inheritance.

Another quality of idiomatic Go code is that concurrent algorithms prefer channels over locking mechanisms (unless the performance penalty of using channels is too severe). I don't have immediate examples coming to mind on this one though, since the use of channels and mutexes tends to be quite intertwined with the algorithm in question.

Thank you, I’ve been looking for something more actively used than https://github.com/google/grumpy.
