[problems] Dynamic loader on OSX
by Yves Degoyon 22 May '02

22 May '02

hi, i've been trying today to install and test a full-featured PD on OSX ( with most externs and libraries ). apart from some keyboard problems ( it doesn't seem to catch "~" from the french iBook layout ( yeah, it's tricky : keys are : <alt>n ) + missing <apple>C/<apple>V for cut & paste ), i have more serious issues with the dynamic loader : a/ although i start it with the command : "pd -path externs" and that my objects are all there ( in externs/*.pd_darwin ), it seems that after one loading or two, the path is lost and it doesn't find my objects anymore.....sh****! b/ the dynamic loader also firmly refuses to load two objects which define the same symbol..... too bad.... all LADSPA plugins define the same routines.... they won't load....yes, the good news here is that i compiled LADSPA plugins for OSX and even the plugin~ which needed some modifications. so, finally, very few patches are working : i can only load 2/3 objects and i have to be cautious with the ones i choose : they should not define the same routine. any OSX guru out there ?? thanx for providing some workarounds. cheers, yves

hi, so, to repeat myself in Pd-jargon: wouldn't it make sense to give messages with text the selecton "symbol" and messages with white space the selector "list"?

PD Documentation project
by Dupras, Martin 22 May '02

22 May '02

The thread on the PD documentation project seems to have died, and I presume that it is because no one is really sure how to go about it, or no one is willing to commit to actually steer it. I am willing to put myself forward for some of the work, but as with anyone, my time is limited. Unless someone has a better idea, I would like to propose this following chain of actions. 1) discussion on list of the break up and format of the documentation; what outputs should the documentation be delivered as (HTML, RTF?, others?); how should the documentation be indexed, markup'ed and stored (docbook? XML?) what volumes/books/chapters should the documentation divided into [e.g.: book: PD chapter: pd syntax/principles (as per existing docs) chapter: object list (as per Max reference manual) book: GEM chapters... book: Source Code info chapter: how PD works chapter: how to compile PD subsection: how to solve the compilation problems in RH 7.x chapter: how to program externals book: specific subjects in PD (kind of like the Csound book) etc. ] what existing documentation should be adapted/modified/recycled to fit in above 2) division of the work between volunteers as: - editors, coordinating the documentation project - documentation specialists (for lack of a better term) who will supervise and adapt how the documentation is stored, modified, maintained, version'ed, etc. - writers, who will write the actual documentation and reference In a dream world, I would personally like to see a centrally maintained, always up-to-date, moderated on-line system, through which submissions can be made (with online forms, say); it would be beneficial to facilitate inline graphics (such as jpeg) for diagrams and screenshots; there should be automated links to object names and such; and there should be a way for people to annotate or add corrections online (and credit them of course.) I have had a look at existing documentation projects and systems, and so far I haven't really found anything that does everything in one package. However it is obvious that XML should be the underlying format for storing the content of the documentation, although I don't see what the best way is to do that. - martin

Hi, it seems, you need [list skidoo 23( --> [$2 until $1( Now, wouldn't it make sense to interpret messages with text as symbols, and messages with spaces as lists? I'm sure there's a reason why not.. or is there? J. > hi, > > somehow related is this problem I stumbled over recently: > > dollar signs in messages seem to react strange when they get a two-part > message that starts with a symbol instead of a float. In the attached > patch, I used the example from the html-docs: [23 skidoo( sent to > [$2 until $1( which works fine this way, but not the other way around: > > [skidoo 23( ---> [$2 until $1( > > results in "error: $2: argument number out of range" > > Is this the intended behaviour? > > ciao,

command - value parsing
by Ben Bogart - FMPM/F1999 22 May '02

22 May '02

Hello all, I'm trying to get a simple command - value relationship to work in PD with difficulty. Basically I want a message to have a simple syntax like R 10 which would set the red value of an object to 10. So basically I wanted to use a route to sort the messages according to the first symbol "R" for example. So I have a pack s f which I take it should pack the "R" and the value into one list. problem is that when I put a "print" on the output, rather than getting "R 10" I get "list R 10". Seems to me I'm missing some vital logic about symbols.. Any help would be appriciated. (Oh course I could use other floats as the "commands") but that would be a lot less readable. "0 10" ) Thanks Ben B. Bogart ---------
