Just create -// a new file and start hacking. -// -// The first few files (00*) are independent of what this program does, an -// experimental skeleton that will hopefully make it both easier for others to -// understand and more malleable, easier to rewrite and remould into radically -// different shapes without breaking in subtle corner cases. The premise is -// that understandability and rewrite-friendliness are related in a virtuous -// cycle. Doing one well makes it easier to do the other. -// -// Lower down, this file contains a legal, bare-bones C++ program. It doesn't -// do anything yet; subsequent files will add behaviors by inserting lines -// into it with directives like: -// :(after "more events") -// This will insert the following lines after a line in the program containing -// the words "more events". -// -// Directives free up the programmer to order code for others to read rather -// than as forced by the computer or compiler. Each individual feature can be -// organized in a self-contained 'layer' that adds code to many different data -// structures and functions all over the program. The right decomposition into -// layers will let each layer make sense in isolation. -// -// "If I look at any small part of it, I can see what is going on -- I don't -// need to refer to other parts to understand what something is doing. -// -// If I look at any large part in overview, I can see what is going on -- I -// don't need to know all the details to get it. -// -// Every level of detail is as locally coherent and as well thought-out as -// any other level." -// -// -- Richard Gabriel, "The Quality Without A Name" -// (http://dreamsongs.com/Files/PatternsOfSoftware.pdf, page 42) -// -// Directives are powerful; they permit inserting or modifying any point in -// the program. Using them tastefully requires mapping out specific lines as -// waypoints for future layers to hook into. Often such waypoints will be in -// comments, capitalized to hint that other layers rely on their presence. -// -// A single waypoint might have many different code fragments hooking into -// it from all over the codebase. Use 'before' directives to insert -// code at a location in order, top to bottom, and 'after' directives to -// insert code in reverse order. By convention waypoints intended for insertion -// before begin with 'End'.

Directives -// are shaded dark. Notice the references to waypoints lower down in this -// file. -// -// Layers do more than just shuffle code around. Past the initial skeleton of -// this program (currently 00*-02*), it ought to be possible to stop loading -// after any file/layer, build and run the program, and pass all tests for -// loaded features. (Relevant is http://youtube.com/watch?v=c8N72t7aScY, a -// scene from "2001: A Space Odyssey".) -// -// This 'subsetting guarantee' ensures that this directory contains a -// cleaned-up narrative of the evolution of this codebase. Organizing -// autobiographically allows a newcomer to rapidly orient himself, reading the -// first few files to understand a simple gestalt of a program's core purpose -// and features, and later gradually working his way through other features as -// the need arises. Each step should be as simple as possible (but no simpler). -// -// Programmers shouldn't need to understand everything about a program to hack -// on it. But they shouldn't be prevented from a thorough understanding of -// each aspect either. The goal of layers is to reward curiosity. - -// Includes -// End Includes - -// Types -// End Types - -// prototypes are auto-generated; define your functions in any order -#include "function_list" // by convention, files ending with '_list' are auto-generated - -// Globals -// End Globals - -int main(int argc, char* argv[]) { - if (argc > 1) { - // Commandline Options - } - - setup(); - return 0; // End Main -} - -void setup() { - // End Setup -} - -// Without directives or with the :(code) directive, lines get added at the -// end. |
