Free Compiler Construction Tools: Lexers, Parser Generators, Opt. If you are thinking of creating your own programming language, writing a compiler or interpreter, or a scripting facility for your application, or even creating a documentation parsing facility, the tools on this page are designed to (hopefully) ease your task.
These compiler construction kits, parser generators, lexical analyzer / analyser (lexers) generators, code optimzers (optimizer generators), provide the facility where you define your language and allow the compiler creation tools to generate the source code for your software. If you want a (printed) book on compiler construction, you might want to check out the famous Compilers: Principles, Techniques, and Tools by Aho, Sethi and Ullman. The "Dragon book", as it is affectionately called by some, is regarded by many as the standard book on writing compilers.

Bash by example, Part 3. Enter the ebuild system I've really been looking forward to this third and final Bash by example article, because now that we've already covered bash programming fundamentals in Part 1 and Part 2, we can focus on more advanced topics, like bash application development and program design.
For this article, I will give you a good dose of practical, real-world bash development experience by presenting a project that I've spent many hours coding and refining: The Gentoo Linux ebuild system. I'm the chief architect of Gentoo Linux, a next-generation Linux OS currently in beta. One of my primary responsibilities is to make sure that all of the binary packages (similar to RPM packages) are created properly and work together. As you probably know, a standard Linux system is not composed of a single unified source tree (like BSD), but is actually made up of about 25+ core packages that work together. Back to top Why bash? Bash is an essential component of the Gentoo Linux ebuild system. . #! #! #! $ . Popular RFC Title Index 1. How to Design Programs. Programming Texts/Tutorials. Biggus Biggus is a pure-Python library for handling very large (i.e. too large for system memory) n-dimensional arrays.
It has two main components: Representation, lazy indexing, and conversion to persistent files and NumPy arrays; andLazy calculation. At the core of Biggus is the Array which provides a simple, consistent, NumPy-esque interface to n-dimensional data which avoids reading data until explicitly requested by user code. Commonly these Array objects are created by wrapping "concrete" data sources such as HDF5 variables, netCDF4 variables, or even just NumPy arrays. Once created, Array objects can be concatenated and stacked to form new Array objects, which can themselves be concatenated and stacked as required. In addition, all Array objects can be indexed to extract subsets. User code may request any Array object be saved to a "concrete" data form (e.g. Linkers and Loaders. These are the manuscript chapters for my Linkers and Loaders, published by Morgan-Kaufman.
See the book's web site for ordering information. The text in these files is the unedited original manuscript. M-K has fine copy editors, who have fixed all the minor typos, spelling, and grammar errors in the printed book, but if you come across factual errors I'd still appreciate help getting all the details of linking and loading as complete and correct as possible. I will collect errata and fix them in subsequent printings. The figures here are scans of hand-drawn sketches which have been redrawn for the book.

For the last twelve years, I've made my living writing computer games and selling them over the Net using the marketing technique that was once charmingly known as shareware. What this means is that I start with a blank screen, start coding, and, a few tens of thousands of lines of code later, I have something to sell. This means that, if I make a stinky mess, I'm doing it in my own nest. When I'm chasing down a bug at 3 a.m., staring at a nightmare cloud of spaghetti code, and I say, "Dear God, what idiot child of married cousins wrote this garbage? ", the answer to that question is "Me. " Courses - Google Code University - Google Code.
