CritBit-Tree implementation for pike
by Tobias S. Josefowitz 03 Mar '11

03 Mar '11

We have been working on a CritBit tree implementation for pike. We would like to get it upstream, however we have made a few changes elsewhere that may need discussion: precompile.pike templating: we added a simple template support to precompile.pike. It basically replaces a set of identifiers in the template file before precompilation. The syntax is admittedly not very beautiful. Autodoc to support global paths in AUTODOC_SRC_IN: we could not figure out how to make the autodoc generator to extract docs from several .cmod files without the AUTODOC_SRC_IN feature applied on the generated .c-files with absolute paths. You can check it out using git from http://fortranland.com/git/pike. The branch is called critbit. We have not done any testing on non x86 machines. It would be nice if someone could run the testsuite on some big endian machine. Also, we only compiled on linux machines. There might be problems on other environments because of the gcc intrinsics we are using for prefix searches. Currently there are trees supporting float, integers and pike strings and two derived types for ipv4 ip addresses and date objects. The lookup, insert and delete operations are comparable in speed to pike mappings (1.X slower in our tests). In worst case scenario critbit trees can be slow in insert and lookup (e.g. keys like "a"*i). However, critbit trees should be more memory efficient in many cases because of the mapping overhead. Also, they support several operations that mappings don't offer, namely, iteration in lexicographical order, range lookup and finding biggest/smallest index, etc. We have written quite extensive tests and a complete documentation, which you can find at http://fortranland.com/refdoc/modref/ex/predef_3A_3A/ADT/CritBit.html Any hints, suggestions, bugreports and comments are welcome. arne and tobias

SDL.get_video_info() docs
by Matthew Clarke 31 Jan '11

31 Jan '11

Hi Slow week again :( but I got this one function done. I haven't changed the return type but I'm sure it's not right. It's given as void|object but I can't see how it would ever not return anything. If the video device is uninitialized, Pike returns 0 (the original C function returns NULL). Wouldn't that be a special type of (null) object rather than void? Thanks & regards, larcky.

when installing pike 7.8.530, dumped .o files are installed only with user permissions

hi, when installing pike, dumped .o files are installed only with user permissions: i am building and installing pike on fedora 12: the same is the case for the previously released 7.8.352 ls -la /usr/local/pike/7.8.530/lib/modules/*.o -rw------- 1 root root 16734 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Arg.pmod.o -rw------- 1 root root 42028 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Array.pmod.o -rw------- 1 root root 570 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/__builtin_dirnode.pmod.o -rw------- 1 root root 60 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/__builtin.pmod.o -rw------- 1 root root 2060 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Colors.pmod.o -rw------- 1 root root 1077 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Error.pmod.o -rw------- 1 root root 409 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Float.pmod.o -rw------- 1 root root 30 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Fuse.pmod.o -rw------- 1 root root 12260 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Getopt.pmod.o -rw------- 1 root root 30 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/GTK2.pmod.o -rw------- 1 root root 30 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/GTK.pmod.o -rw------- 1 root root 13077 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Gz.pmod.o -rw------- 1 root root 3032 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/_Image_DWG.pmod.o -rw------- 1 root root 14587 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/_Image_PSD.pmod.o -rw------- 1 root root 14475 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/_Image_PS.pmod.o -rw------- 1 root root 9857 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/_Image_TIFF.pmod.o -rw------- 1 root root 25185 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/_Image_XCF.pmod.o -rw------- 1 root root 9100 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/_Image_XPM.pmod.o -rw------- 1 root root 5624 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Int.pmod.o -rw------- 1 root root 29270 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Java.pmod.o -rw------- 1 root root 1809 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Local.pmod.o -rw------- 1 root root 4488 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Mapping.pmod.o -rw------- 1 root root 10856 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Math.pmod.o -rw------- 1 root root 112 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Multiset.pmod.o -rw------- 1 root root 201 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Object.pmod.o -rw------- 1 root root 16228 2011-01-26 17:49 /usr/local/pike/7.8.530/lib/modules/Process.pmod.o -rw------- 1 root root 784 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Program.pmod.o -rw------- 1 root root 3608 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Regexp.pmod.o -rw------- 1 root root 186 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/System.pmod.o -rw------- 1 root root 17363 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Thread.pmod.o -rw------- 1 root root 2510 2011-01-26 17:48 /usr/local/pike/7.8.530/lib/modules/Yp.pmod.o greetings, martin.

'make doc' doesn't work
by Matthew Clarke 23 Jan '11

23 Jan '11

Hello I hope this isn't just my machine that's playing up because I'm using my netbook at the moment rather than my main PC, but... With the latest Pike checked out from git, 'make doc' fails with this error message: PikeParser: expected identifier, got "(" (/home/matthew/Downloads/Pike-devel/pike/src/builtin.c:5611) Hope someone can make sense of that! Regards, larcky P.S. no problems at all with 'make' and 'make install'

SDL
by Matthew Clarke 23 Jan '11

23 Jan '11

Hi Not done much this week but here's some documentation for SDL.blit_surface(). I've left out some of the subtleties in the original C docs and just filled in the basics. I hope I'm right in changing the method signature: I had a look at the PIKEFUN in SDL.cmod and tried out a small example and it seems you can set those last two args (srcrect & dstrect) to '0' or leave them out to get default behaviour. Also, with SDL.Rect, is this the only way you can initialize an SDL.Rect object to, say, values 50, 50, 100, 100? SDL.Rect r = SDL.Rect(); r->x = 50; r->y = 50; r->w = 100; r->h = 100; Before I tried this: SDL.Rect r = SDL.Rect( 50, 50, 100, 100 ); but it didn't compile, presumably because there's no create() method matching that pattern? Would that be a useful thing to add, or is there a smarter way of setting the initial values? Thanks and regards, larcky :)

SDL docs
by Matthew Clarke 15 Jan '11

15 Jan '11

Hi I'm still working through the SDL module - please find attached my latest diff file for documentation. As well as adding things I've also fixed a few minor typos and added some examples in places. I noticed that SDL.get_key_state() refers to SDL.pump_events() but that method isn't in the SDL.cmod file. I took the liberty of adding it as it's a simple C function to call (no args and no return value). Hope that's OK - I've tested it and it works fine on my system. Thanks & best wishes, larcky

Object - XML - object

I'm looking for code to translate objects to XML and back with absolutely NO pike specific encoding of any kind. Is this already available or do I have to make this myself? -- Met vriendelijke groet / With kind regards / mit besten Grüßen, Coen Schalkwijk Software Engineer coen.schalkwijk(a)rtl.nl <mailto:coen.schalkwijk@rtl.nl> coen(a)rtlinteractief.nl <mailto:coen@rtlinteractief.nl> +31 (0)35 671 8915

SDL.Music
by Matthew Clarke 11 Jan '11

11 Jan '11

Hi I did some doc comments for Pike's very nice SDL.Music module - please see attached. I also fixed a couple of typos in the SQLite cmod file. I only mention that because it was stopping 'make doc' from finishing :( I left out SDL.Music->fading() because you really need the constants MIX_NO_FADING, MIX_FADING_OUT and MIX_FADING_IN for it to make sense, but Pike doesn't seem to have bindings to them. Thanks, larcky
