Sources for "Object-Oriented Programming with ANSI-C" (rerelease 02-01-04) Copyright (c) 1993 Axel T. Schreiner, University of Osnabrueck, Germany contact ---------------------------------------------------------------- mail: Axel T. Schreiner, Department of Computer Science, Rochester Institute of Technology, room 10-1188, 102 Lomb Memorial Drive, Rochester NY 14623-5608 USA http://www.cs.rit.edu/~ats/, phone +1.585.475.4902, fax +1.585.475.7100 mailto: ats@cs.rit.edu legalese --------------------------------------------------------------- While you may use this software package, neither I nor my employers can be made responsible for whatever problems you might cause or encounter. While you may give away this package and/or software derived with it, you should not charge for it, you should not claim that ooc is your work, and I have published my own book about ooc before you did. The same restrictions apply to whoever might get this package from you. executive summary ------------------------------------------------------ ooc is a technique to do object-oriented programming (classes, methods, dynamic linkage, simple inheritance, polymorphisms, persistent objects, method existence testing, message forwarding, exception handling, etc.) using ANSI-C. ooc is a preprocessor to simplify the coding task by converting class descriptions and method implementations into ANSI-C as required by the technique. You implement the algorithms inside the methods and the ooc preprocessor produces the boilerplate. ooc consists of a shell script driving a modular awk script (with provisions for debugging), a set of reports -- code generation templates -- interpreted by the script, and the source of a root class to provide basic functionality. Everything is designed to be changed if desired. There are manual pages, lots of examples, among them a calculator based on curses and X11, and you can ask me about the book. ooc as a technique requires an ANSI-C system -- classic C would necessitate substantial changes. The preprocessor needs a healthy Bourne-Shell and "new" awk as described in Aho, Weinberger, and Kernighan's book. ooc was developed primarily to teach about object-oriented programming without having to learn a new language. If you see how it is done in a familiar setting, it is much easier to grasp the concepts and to know what miracles to expect from the technique and what not. Conceivably, the preprocessor can be used for production programming but this was not the original intent. Being able to roll your own object-oriented coding techniques has its possibilities, however... technical details ------------------------------------------------------ Most sources should be viewed with tab stops set at 4 characters. The original system ran on NeXTSTEP 3.2 and older, ESIX (System V) 4.0.4, and Linux 0.99.pl4-49. This rerelease was tested on MacOS X version 10.1.2 and Solaris version 5.8. You need to review paths in the script 'ooc/ooc' before running anything. Make sure the first line of this script points to a Bourne-style shell. Also make sure that the first line of '09/munch' points to a (new) awk. The rereleased 'ooc' awk-programs have been tested with GNU awk versions 3.0.1 and 3.0.3. Previous versions did not support AWKPATH properly (but this is not essential). The makefiles could be smarter but they are naive enough for all systems. This is a heterogeneous system -- set the environment variable $OSTYPE to an architecture-specific name. 'make' in the current directory will create everything by calling 'make' in the various subdirectories. Each 'makefile' includes 'make/Makefile.$OSTYPE', review your 'make/Makefile.$OSTYPE' before you start. The following make calls are supported throughout: make [all] create examples make test [make and] run examples make clean remove all but sources make depend make dependencies (if makefile.$OSTYPE supports it) Make dependencies can be built with the -MM option of the GNU C compiler. They are stored in a file 'depend' in each subdirectory. They should apply to all systems. 'makefile.$OSTYPE' may include a target 'depend' to recreate 'depend' -- check 'makefile.darwin1.4' for an example. contents --------------------------------------------------------------- The following is a walk through the file hierarchy in the order of the book: makefile dispatch standard make calls to known directories make/ Makefile.* boilerplate code for */makefile */ depend make dependencies makefile create and test 01/* chapter 1: abstract data types sets Set demo bags Bag demo: Set with reference count 02/* chapter 2: dynamic linkage strings String demo atoms Atom demo: unique String 03/* chapter 3: manipulating expressions with dyn. linkage postfix postfix output of expression value expression evaluation infix infix output of expression 04/* chapter 4: inheritance points Point demo circles Circle demo: Circle: Point with radius 05/* chapter 5: symbol table with inheritance value expression evaluation with vars, consts, functions 06/* chapter 6: class hierarchy and meta classes any objects that do not differ from any object ooc/* ooc preprocessor ooc command script; review 'home' 'OOCPATH' 'AWKPATH' awk/*.awk modules awk/*.dbg debugging modules rep/*.rep reports rep-*/*.rep reports for early chapters man/ooc.1 manual page (for final version) 07/* chapter 7: ooc preprocessor; use ooc -7 points Point demo: PointClass is a new metaclass circles Circle demo: Circle is a new class queue Queue demo: List is an abstract base class stack Stack demo: another subclass of List 08/* chapter 8: dynamic type checking; use ooc -8 circles Circle demo: nothing changed list List demo: traps insertion of numbers or strings 09/* chapter 9: automatic initialization; use ooc -9 munch awk program to collect class list from nm -p output circles Circle demo: no more init calls list List demo: no more init calls man/munch.1 manual page 10/* chapter 10: respondsTo method; use ooc -10 cmd Filter demo: how flags and options are handled wc word count filter sort sorting filter, adds sort method to List 11/* chapter 11: class methods value expression evaluator, based on class hierarchy value x memory reclamation enabled man/retrieve.2 manual page c.12/* chapter 12: persistent objects value expression evaluator, with save and load 13/* chapter 13: exception handling value expression evaluator with exception handler except Exception demo 14/* chapter 14: message forwarding makefile.etc (naive) generated rules for the library Xapp resources for X11-based programs hello LineOut demo: hello, world button Button demo run terminal-oriented calculator cbutton Crt demo: hello, world changes into a crun curses-based caluclator xhello XLineOut demo: hello, world xbutton XButton demo with XawBox and XawForm xrun X11-based calculator with callbacks man/* manual pages *.1 tools *.2 functions *.3 some classes *.4 classes in chapter 14 hp700 hp/ux ------------------------------------------------------------ c.07 Object.dc extern ... static ... draws a warning, but uses static. c.08 does not trap type checking use _SIGBUS rather than SIGBUS c.12 munch botched -- nm does not output static data symbols. it looks like we have to generate fake things with ooc or we have to produce classes.c on another architecture.

Symbol.dc strerror() does not exist. Object.dc/retrieve() stdlib.h declares char * bsearch(), rather than void *.
