Here is a new release of GridFlow (a multi-dimensional dataflow processing library for Ruby, jMax and PureData, specialized in pictures and video)

version 0.6.3 (2002.12.06):
- removing the custom leak detector ("Valgrind" program used instead)
- removed all (?) memory leaks
- videodev: new options: frequency, transfer [read|mmap], noinit
- profiler summary code rewritten
- profiler wrapper code removed
- x11: option setcursor <0-63>, option hidecursor
- x11: outlet 0 tells cursor position / button state
- more C++ification of the code
- many bugs fixed
former version 0.6.2 was released on 2002.09.17

I found a bug in the file reader that causes it to always rewind after the first picture when there are several pictures in the same file. But since the bug is in scriptable code, then you can fix it yourself easily by putting this code in ~/.gridflow_startup :
require "gridflow/format/main"
GridFlow::GF_VERSION=="0.6.3" and
module GridFlow
class Format
def rewind_if_needed
thispos = (@stream.seek 0,IO::SEEK_CUR; @stream.tell)
lastpos = (@stream.seek 0,IO::SEEK_END; @stream.tell)
thispos = 0 if thispos == lastpos
@stream.seek thispos,IO::SEEK_SET
rescue Errno::ESPIPE # just ignore if seek is not possible
end
end
end

if anyone has trouble installing GridFlow, please tell me.
in particular, i would like to know whether "make install" fails to overwrite the former version of gridflow.so; this results in "gridflow version 0.6.2" being shown in the jMax/PD log, and most of the problems of 0.6.2 showing up even though the real 0.6.3 is many times more stable.
if this is the case, tell me which version of Ruby you are using, and you may remove the old gridflow.so manually by doing this:
rm -i find /usr/lib/ruby -name gridflow.so
make install
(if ruby is not in /usr/lib/ruby then replace that name by the appropriate name, maybe /usr/local/lib/ruby)
I would get that problem fixed by next release.

Some notes about 0.6.3 :
I still have no evidence the aforementioned problem actually exists. I've had one report and assumed it was something else... however that "something else" only occurred when reinstalling from a shared filesystem when the clock is not synchronised, and that i was reinstalling too often... Ruby's installer will only install a newer file on top of an older file. I can circumvent that if people think it's a good idea to.
Now, another thing: I have gotten almost no feedback about this version of GridFlow. There's something I might not have advertised properly: 0.6.3 is _NOT_ crashy; it's possibly 1000 times less so than the previous version, which had a real problem with that.
So, for PureData users: this is the first version of GridFlow that actually works quite well with PureData. The main differences with the jMax side are now only:
- only 2 examples for PD; 17 examples for jMax
- 8 abstractions are still jMax-only
- the list syntax is uglier in PD

version 0.6.4 (2002.12.23):
- can now decode JPEG (using libjpeg.so)
- many bugs fixed (especially in file formats)
- operators: log* added; tanh renamed to tanh*
- @two,@three,@four are no longer specific to the jMax side
- format grid: option headerless for reading any kind of file
- format grid: option headerful (revert to actual .grid format mode)
- fixed problems with GNU C++ version 3
- format ppm: accelerated writing
- format modifier gzfile: gzip support also works with [@out]
- format x11: the "here" specifier is now optional
- added @checkers
- [@scale_by {y x}] for different y,x scale factors
- [@in blah blah] means "open blah blah" -> [@in] (and same with @out)
- added @downscale_by with or without smoothing
- format targa: can now decode 32 bit RGBA
- @layer: combines RGBA foreground with RGB background, yielding RGB.
- format grid options: endian big, endian little, endian same
- formats ppm,grid: use 'option rewind' to overwrite same file (by default, rewind is no longer done after each frame) ('option rewind' also rewinds on reading)
(the previous version was released on 2002.12.06)
