'packages' module and versioning
by Hans-Christoph Steiner 15 Oct '03

15 Oct '03

I just committed the first files to the new 'packages' module in CVS: 'win32_inno". Its the start of a installer maker for the whole Pd package a la the MacOS X installer. Soon I hope to have 'debian_deb' and 'planetccrma_rpm' (or 'redhat_rpm'?) in there from Guenter and Nando. I'll be moved 'darwin_pkg' to there as well. Once these are all in place, we can start making coordinated releases with version numbers instead of dates. We need to create a versioning scheme for releases from CVS, something like 0.37 rel 1. Miller uses a '-' in his versions, so it won't work here. So it would be something like this: 0.37 rel 1 0.37-1 rel 5 0.37-cvs rel 2 Just a thought... there is probably a better way. .hc zen \ \ \[D[D[D[D

Non-branching clipping algo...
by Luigi Castelli 13 Oct '03

13 Oct '03

Hi, I am trying to find a way to clip incoming values to a range from 0.0 to 1.0 without using branching. I found a bunch of algorithms on musicdsp.org to achieve clipping without branching but none were satisfactory. What I am really aiming for is to find a way to modify the tabfudge technique used in d_osc.c to achieve clipping instead of wrapping. Is that possible ? Thanks for any help or suggestion. - Luigi ===== Luigi Castelli superbigio(a)yahoo.com __________________________________ Do you Yahoo!? The New Yahoo!

'packages' modules
by Hans-Christoph Steiner 11 Oct '03

11 Oct '03

I created the 'packages' module in CVS. I'll move 'darwin_pkg' to it soon. It would be great to have a 'debian_deb' folder in their with everything needed to compile the .debs of Pd and all the CVS goodies. .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

Patch to fix up man page installation under Linux.
by Luke Yelavich 10 Oct '03

10 Oct '03

Hi all Attached is a patch to fix up a problem when it comes time to install the man pages. On my system at least, being Slackware 9.0 with latest CVS, the man pages are being dumped in /man, instead of prefix/man, in this case prefix being /usr. The patch also fixes the problem with man pages not being removed correctly. One extra man/ was in the uninstall procedure. Hope this is of some use.

pd.tk question
by Hans-Christoph Steiner 09 Oct '03

09 Oct '03

I can pretty much understand pd.tk at this point, I just have one lingering question: on lines starting with "pd", what is being called? Here are some examples: proc menu_vradio {name accel} { pd [concat $name vradio $accel \;] } proc menu_vumeter {name accel} { pd [concat $name vumeter $accel \;] } proc menu_mycnv {name accel} { pd [concat $name mycnv $accel \;] } My guess is that it is calling "static int pdCmd(ClientData cd, Tcl_Interp *interp, int argc, char **argv)" from t_tkcmd.c, but I don't entirely understand how. Any pointers would be appreciated. .hc ________________________________________________________________________ ____ There is no way to peace, peace is the way. -A.J. Muste

CVS pd linux build updated and inventory of changes
by guenter geiger 08 Oct '03

08 Oct '03

Hi, I have updated the linux build on CVS, basically disabling portaudio builds as it is done in the official 0.37 version. We might have to add portaudio at some point, could be that it solves some problems that we have with alsa. Other than that I read through the differences, and here is what makes the CVS version different from upstream: - some t_int int issues, that caused build failures on 64 bit architectures - array drawing dirty flags - experimental quoting with '"' as in "hello world" .. but this is a hack and has probably to go away Don't ask who did that :) - SIMD functions for Windows (added by Thomas) I think the SIMD functions are a great thing, and eventually it would be good to have these on all architectures. In this case it would be nice to have the assembler blocks in macros, and eventually in a different file (might be a .h as well). Otherwise the code will get terribly fragmented and hard to read. What do you think ? is this feasable ? Greetings, Guenter
