Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

Tested this sample with Nim 1.0.6 on Windows 8.1

Install Nim Game Library

nimble install nimgl

Get glfw3.dll Go to GLFW web site, go to Download page and download Windows pre-compiled binaries. Unzip it and copy glfw3.dll to where you run sample program.

Let's Destroy C

I have a pet project I work on, every now and then. CNoEvil.

The concept is simple enough.

What if, for a moment, we forgot all the rules we know. That we ignore every good idea, and accept all the terrible ones. That nothing is off limits. Can we turn C into a new language? Can we do what Lisp and Forth let the over-eager programmer do, but in C?

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).

	import tables, options, sugar

	type
	Constraint*[V, D] = ref object
	# Base class for all constraints
	variables*: seq[V] # The variables that the constraint is between
	satisfied*: proc (assignment: Table[V, D]): bool

	Csp*[V, D] = object
	# A constraint satisfaction problem consists of variables of type V

	import asynchttpserver, asyncdispatch, os


	proc handler(req: Request) {.async.} =
	echo "request for path ", req.url.path
	let cwd = getCurrentDir()
	let file = cwd / req.url.path
	if fileExists(file):
	await req.respond(Http200, file.readFile())
	else:

	# nim c -r --threads:on --gc:orc

	import cpuinfo, os, random, locks, deques

	type
	WorkReq = ref object
	id: int

	WorkRes = ref object
	id: int
