资源说明:ABC language examples and docs
This repository contains implementations and examples for the ABC programming language, a predecessor of Python designed by Leo Geurts, Lambert Meertens and Steven Pemberton. The implement/ directory contains implementations downloaded from the book Web site [1]. The text and URLs below are from the same source. [1] http://www.idhub.com/abc/. The steven/ directory contains a mirror of HTML and PDF files from Steven Pemberton's homepage at CWI [2], accessed in October 2011. [2] http://homepages.cwi.nl/~steven/abc/ The CWI FTP server mentioned in some links cannot be found (as of Oct. 2011), but some of the papers mentioned can be found via OAI-PMH at the CWI OAI server [3], or via CiteSeerX [4].

[5] http://homepages.cwi.nl/~steven/abc/implementations/abc-windows.zip The workspaces/ directory was created by hand, but the workspaces/abc/ directory and its contents were created by the ABC environment as the system was used, after the HOME variable in ABC/abc.bat was changed to point to workspaces. The directory workspaces/abc/first contains the >first default workspace. Read the FILES section in ABC/abc.hlp for a description of the files that hold workspaces. ############################################################## ABC Programmer's Handbook ABC is a programming language designed from the ground up to be easy to use. Every single thing about it has been well thought out. The result is a language that is ideal for teaching and learning about programming, but also a language that is uniquely powerful and flexible. ABC Programmer's Handbook The user friendly programming language; powerful and easy to use. ‘An incredibly elegant and powerful language, aimed at non-professional programmers’ Guido van Rossum – ABC team member and creator of Python Everybody knows about designing web sites and computer systems so that they are easy to use, but what would happen if you designed a programming language with the same goals? The answer is ABC; a language that was designed on a ‘clean sheet’ with the goal of delivering an easy-to-use language ideal for teaching and learning about programming. ABC is more readable than other languages; no obscure commands. It is more concise than other languages; equivalent programs written in C are five times as long. It is more powerful than other languages; its perfect choice of high-level data types make it an idea tool for serious programming. ABC was one of the inspirations for the Python programming language and Python shares key ideas and features of ABC. This book provides a hands-on introduction to the language including many programming examples along with a users guide and a complete definition of the language. The language is available free to run on PCs, Macs and UNIX. (See below). This book is published by Bosko Books 2005. (ISBN: 0954723945) Download ABC You can download these implementations of ABC for free. They are copyrighted (ie. not public domain), but they are free. This means that you may give them to – or get them from – your friends. PC: http://www.idhub.com/abc/implement/pc/abc-pc.zip This is a new version with much better memory handling than the previous version. Included are two .pif files for running abc on Windows 98 and Windows 2000. Unpack it in c:\Program Files\ABC (or read the file readme.txt). UNIX: http://www.idhub.com/abc/implement/unix/abc-unix.tar.Z For Unix (These are sources: also compilable on other machines if you have the right environment, such as Cygwin for the PC). LINUX: http://www.idhub.com/abc/implement/linux/abc-redhat-linux.tar Binaries compiled under Redhat 7.3. See the readme for where to put the files. MAC: http://www.idhub.com/abc/implement/mac/abc-mac.sit.hqx For the Mac (not tested on newer Macs).
