Aaargh!

Well, after a lot of work, the command line version of my program is now functional. It still needs some polishing, and a lot of testing. Plus there’s a GUI to do, and a manual to write…
But, nevertheless, it lives!
I’ve been getting annoying warnings from Apple’s GDB recently about out-of-date symbol files that it is ignoring, and I couldn’t find any way to sort it out… until today, I noticed that one of them had a path associated with it, so I went snooping.
Anyway, to cut a long story short, if you start getting these warnings, the command you need is
sudo /usr/libexec/gdb/cache-symfiles
I think we need an FAQ for the Apple Cocoa-dev mailing list, so I’ve written a draft for people to peruse and comment upon.
This FAQ is seriously out of date, so I’ve removed it.
One thing that seems to annoy people about NSImage is the fact that although
you can get TIFF data by using the -TIFFRepresentation method,
there is no obvious way to turn one directly into a PDF. This seems like an
odd omission when you consider that Quartz directly supports PDF…
anyway, I thought I’d rectify the situation by posting some code that
implements a -PDFRepresentation< method.
If you want to take a look, it’s in my mercurial repository.
Older programs (and older programmers) sometimes use octal (base-8) to represent characters, so I added some additional numbering on the chart to help you out if you’re given (or want) an octal representation of an ASCII character. I’ve put the revised version of my ASCII chart where the original was.
Another useful thing to have if you’re a C programmer is an ASCII chart; sadly there aren’t very many readily-available charts that contain all the information you might want, so, in the immortal words of Blue Peter, “here’s one I made earlier”.
Far too many people don't know how the operator precedence works for C, Objective C or C++, which means they write code that would scare even a Lisp programmer (i.e., far, far too many parentheses [that's brackets, for those that don't know]). This isn't helped by the fact that it's hard to find a precedence table; even the specification doesn't contain one (the precedence information is encoded in the grammar rules in the spec.).
Anyway, here's a precedence table that I've written based on the C99 spec.
Well, it’s nearly the end of August and I’m still bashing away at the keys trying to get my program to a state where I can sell it. There have been some interesting challenges so far and I can see a few more lurking on the horizon; still, it shouldn’t be too long now.
I’m just hoping that people will want to buy it when I’ve finished. On the plus side, I’ve had a few more ideas whilst I’ve been working on this project, so I’ve certainly got some interesting work ahead of me :-)
What a cool game :-) Unfortunately, the install program doesn’t seem to be very reliable… I don’t think it’s setting the file date stamps correctly, which caused me problems when I tried to upgrade to version 1.31 using the patch MacSoft just released.
If only MacSoft had followed Apple’s guidelines and made it a drag-n-drop installation. Still, never mind. If you’re having the same problem with the 1.31 patch that I was, then go to the terminal and enter
cd /Applications/Neverwinter\ Nights
touch -d "May 8 2003" dialog.tlk
touch -d "Feb 7 2003" patch.key
touch -d "Feb 7 2003" data/patch.bif
then run the update installer. In my case, it thought it had finished after updating just patch.bif; if this happens to you, just run it again (or click “Continue”). If all goes well, it should have updated the files listed here. The dates on the dialog.tlk and patch.key files were still wrong when I’d finished, but it seems to have updated them.
Just in case you want to check, here are the MD5 sums of the files I have after installing the patch:
