It's OK, I was lurking through that whole thread and directly found your posts in it to be useful. So the effort was not for naught.

From here if it exists in java, certainly some one needed it in another language and ported it or wrote one like that. a advice from me, after 10 years of programming, don't limit your thinking to one language. knowing programming make you to be able to learn any language you want very quick.knowing a language, is not so easy to learn programming.more over, best solutions in programming are composed from parts writen in different languages.----- Original Message ----- From: "Tyler Littlefield" <tyler@xxxxxxxxxxxxx>To: <programmingblind@xxxxxxxxxxxxx> Sent: Tuesday, July 14, 2009 3:46 PMSubject: Re: game development question:reading and writing game data to and from filesJust because something exists in one language doesn't mean it will exist in another.

You can not exclude what's happening in the other languages world, saying that I am using c/c++ why do you speak about java. In my work time i solved a lot of problems in dpotnet seeing java examples. Viceversa, I've liked very much the aspnet concept "code separation" and I searched for something similar in java and I found jsf. ----- Original Message ----- From: "Tyler Littlefield" <tyler@xxxxxxxxxxxxx>To: <programmingblind@xxxxxxxxxxxxx> Sent: Monday, July 13, 2009 11:20 PMSubject: Re: game development question:reading and writing game data to and from filesI'm not using java...----- Original Message ----- From: "black ares" <matematicianu2003@xxxxxxxxxxx>To: <programmingblind@xxxxxxxxxxxxx> Sent: Monday, July 13, 2009 2:06 PMSubject: Re: game development question:reading and writing game data to and from filesjava has the serialization concept, so for it use ObjectOutputstream and objectinputstream. You can give write(obj) and that is all.regardless of the type of the object. Sure, it can be a map, an array list, etc.Also java implements the java.util.properties class and concept where files with key/value pairs can be saved and loaded easily. Just search and don't try to get complex things for simple tasks.That is the reason that I've told that I see that solution as a over engineered.You want to use bison flex and co, which are powerfull parsing tools, for simply write some data and read it back.This is like I will use a spaceship to go from londra to new york.----- Original Message ----- From: "Tyler Littlefield" <tyler@xxxxxxxxxxxxx>To: <programmingblind@xxxxxxxxxxxxx> Sent: Monday, July 13, 2009 6:40 PMSubject: Re: game development question:reading and writing game data to and from filesum, a very very very long line, possibly? I know you could fwrite the struct, but that's kind of rough, no?I guess I could write in all the data, then I'd have to read it all back, but I'm not quite sure how to do a binary dump of multiple maps. I'd like to get this done kind of soonish, as it's the only thing holding me up, though. ----- Original Message ----- From: "Sina Bahram" <sbahram@xxxxxxxxx>To: <programmingblind@xxxxxxxxxxxxx> Sent: Monday, July 13, 2009 9:33 AMSubject: RE: game development question:reading and writing game data to and from filesHow is this not a oneliner in c, c++, java, python, perl, or lisp?

It's similarif I prefer a binary dump.The fact that C++, Java, and other languages don't have this simple feature blows me away. How hard is it to auto-traverse your data and print it to a file, and to load that same file later? I'm amazed atthe waste of effort and time programmers spend on this automatible task. Anyway, for the vast majority of programmers without such simplesolutions available, here's what I recommend. Print your data to afile. If flex/bison is too complex, then use fscanf. It's really that simple. Extra credit if you make your save file a list of commands that recreate your data when executed.

However, be warned, it will make your brain hurt. I do a semi-object-oriented style of C, based on a database code generator I maintain at datadraw.sf.net. It keeps all the data in-memory rather than on disk, and has an interface somewhat like mysql, but with speed that's faster than plain C. When I want tosave, I have the database manager write out an ASCII database, similar to what you get with mysqldump. As users take actions that modify the database, I log the commands that modified it to a log file, so to get to the current state, I load the ASCII database, and replay the log file. If I wanted all this automated, I'd use a persistent DataDraw database, but I prefer the version where I replay commands from thelog file.I would recommend you don't do what I do. It's way cooler and moreefficient and easier in the long run to deal with than a Mysql database, but then again, I wrote the DataDraw tool, and am the leading expert in it's use.For multiple users interacting with a server, I use a simple tool Iwrote called Command Serialiser, at comserial.sf.net. It allowsfront-end tools (typically in PHP for web pages) to connect in a way similar to mysql. My back-end engine reads commands from it one at a time, so it can be single threaded, and uses a simple console stylecommand interface. The overall architecture, I feel, is far more secure, many times faster, and easier to write and maintain thantypical LAMP applications. However, LAMP runs the world. My system currently runs only one web site, and learning it will turn you intoan alien.

An ASCII file that mirrors your classes well has many advantages. You can edit it easily, and it's fairly simple to maintain backwards compatibility with previousversions.
