I have the following simple example of an inter-thread communication problem: I want to run arbitrary "anytime" algorithms in a background thread. An anytime algorithm performs some computation of result type T incrementally, i.e., it sporadically produces newer, more precise results. In Nim parlance, they are probably best represented by an iterator. In the main thread, I now want to wrap such iterators each in its own thread, with the possibility to query the threads for things like "is there a new value available" or "what is the current computation result". Since I'm not familiar with Nim

Going through the second part of Nimrod's tutorial I've reached the part were macros are explained. The documentation says they run at compile time, so I thought I could do some parsing of strings to create myself a domain specific language. However, there are no examples of how to do this, the debug macro example doesn't display how one deals with a string parameter. I want to convert code like: instantiate(""" height,f,132.4 weight,f,75.0 age,i,25 """) …into something which by hand I would write like: var height: float = 132.4 var weight: float = 75.0 var age: int = 25 Obviously this example

I'm trying to emulate in C++ a distinct type from the Nim programming language . The following example won't compile in Nim because the compiler catches the variables e and d having different types ( Error: type mismatch: got (Euros, float) ) despite both being a float at the binary level: type Euros = distinct float when isMainModule: var e = Euros(12.34) d = 23.3 echo (e + d) One way to do this in C++ would be to write a wrapper class for floats. But this doesn't work well with APIs which export the type because the size won't be the same as float. Or even if a class' size matches the

I've been lately using templates and macros, but i have to say i have barely found information about these important types. This is my superficial understanding: typed/expr is something that must exists previously, but you can use .immediate. to overcome them. untyped/stmt is something that doesn't to be defined previously/one or more statements. This is a very vague notion of the types. I'd like to have a better explanation of them, including which types should be used as return. The goal of these different parameter types is to give you several increasing levels of precision in specifying
