Re: Mixed Languages Programming
I have just thought about dynamic "Rosetta Code" - some software that generates simple code for the target language, compiles it and tests the result. It might be useful to learn a new language. For example, in PowerShell, there is some awkward syntax for an array of array wherein : (,(1,2)) If the preceding comma is omitted, it will not be treated as an array of array. My idea is to write some simple code in the language one is familiar and let the program translate it to some other language, while using Guix to summon the necessary compiler for the target language > On Mar 14, 2021, at 10:30, raingloom wrote: > > On Thu, 11 Mar 2021 00:26:41 +0100 > Léo Le Bouter wrote: > >>> On Thu, 2021-03-11 at 08:23 +0900, Yasuaki Kudo wrote: >>> Hello! >> >> Hello! >> >> I think you can use JSON-RPC libraries as modern alternatives to that. >> Also gRPC.

Another interesting possibility is to run everything on WASM without an MMU.

Re: Mixed Languages Programming
Thank you both, It feels like using the web API as the interface between the languages would be the simplest. Guix might come in really handy if the web services are all running on the same Guix machine in which they can share the resources of the OS such as the file system. Then, using RAM-based or the real disk, different processes compiled in different languages can efficiently exchange data! That's something that Guix and Nix can do more easily than using Docker web services on other OSes?

Say Visual Basic, Java, Racket, Haskell, etc I am aware of 3 different kinds of approaches: - writing programs in different languages, with one programming language occupying a whole process (so, web services as you say, or scripts, or an org-mode file, for instance); - extending a "managed" programming language with C or C++ code; in theory it could be possible to do the same for two different programming languages and link both C interfaces together; this is what SWIG (http://swig.org/) does, but using some language in another language that way feels a lot like coding in C; - using a common virtual machine as the target for the compilation of many different languages (like elisp and scheme for guile).

Mixed Languages Programming
Hello! Does anyone have an insight into mixing different programming language? Say Visual Basic, Java, Racket, Haskell, etc I thought one way would be to convert each program into web services but I wonder if there is a more intimate way - I heard of something called Corba long time ago and there is Microsoft's .NET and Java JVM? Is this a topic that is particularly interesting to the Guix community because of interoperability, mixing packages, etc? Cheers, Yasu
