- Well, it's finally happened. The ACE source code has been released under
- the Gnu Public Lisence. In fact, the complete distribution has. This
- represents version 2.4 of the compiler, and the later update to db.lib
- (version 2.61). See docs/history for the details. The primary ACE document
- (ace.doc/ace.fmt/ace.guide) has been annotated with recent changes, e.g.
- re: contact information.
-
- I developed ACE between November 1991 and September 1996. In preparing the
- archive I was reminded again of how much work I've put into this project.
- It was a labour of love, which was driven by my desire for simplicity and
- power in a programming language, but for a variety of reasons I moved on
- to other things. If you want to know more about this, go to my web page to
- see an interview with me a couple of years ago re: the state of ACE, the
- Amiga, and me.
-
- ACE was the first large C project I worked on and I learned so much, but
- made plenty of mistakes along the way.
-
- There are a number of things I feel I should apologise for.
-
- First, for the time it's taken me to make the ACE source code available.
- For a long time, I wasn't sure that I _would_ do so. But since I'm not
- working on it any longer, I want others to have the chance to do this if
- they wish, but not to exploit it by making money from ACE without sharing
- the benefits with others. That's what the GPL gives us.
-
- Second, the source code is a mixture of C and assembler, mostly C. The
- bad news is that it's in K&R C rather than ANSI C. I developed ACE
- using an old but stable C compiler: Sozobon C v1.01. See the ZC directory.
- I had plans to convert it to ANSI C but never got around to it. I recall
- seeing at least one freeware utility for doing this conversion however.
-
- Third, my coding style has changed considerably over the last few years,
- and you'll notice the evolution in some of the ACE sources. My commenting
- tends to be more fanatical nowadays also, although it's adequate in most
- of the ACE sources.
-
- Fourth, there's no makefiles. I used a few scripts (see make directory) to
- generate the compiler and libraries. This works fine, but compared to
- what I'm used to now, it's primitive. It wouldn't be hard to write some
- makefiles for ACE though.
-
- Fifth, no source control system was used. I just kept each version in
- separate directories.
-
- Sixth, there's a single common header file for the whole compiler. These
- days I generally use one header per C file and conditional compilation.
-
- Lastly, there's one small object module (src/lib/obj/LoadIFFToWindow.o) to
- which there is no source code. That's because it's a shared library stub
- for ilbm.lib (which ACE regenerates at run-time). It's used in one place
- (src/lib/c/iff.c)
-
- That's all the negative stuff I can think of. The good news is that the
- source code compiles and produces a compiler and libraries that work. I'm
- not pretending that there are no bugs though. I didn't use bug tracking
- software, so another task I should carry out is the conversion of my
- paper-based problem logs to electronic format. I didn't want to delay
- releasing the ACE source any longer in order to do this.
-
- I also have paper-based plans for how ACE could be improved and expanded,
- which I'm also willing to make available (after suitable conversion) if
- there's demand for it.
-
- I am willing to make this kind of information available and to answer
- questions about the ACE source code and about ACE in general.
-
- I need to thank Daniel Seifert for supplying the necessary guilt level to
- release the ACE source code and I'd like to thank everyone who's been involved
- with ACE since it came into being eight years ago. It was a wonderful
- experience. I came to know many fine people in the Amiga Community during
- the course of the project. I also want to thank my wife Karen, for putting
- up with me during those years when I lived, breathed, and ate ACE.
-
- There's nothing much left to say except that if anyone decides to keep
- developing ACE, or use the source code for some other purpose, I hope
- you spend more time thanking me than cursing me and that you send me
- some mail letting me know what you're doing.
-
- Enjoy.
-
- Best regards
