Re: [PD-dev] Seeking co-maintainers for Scheme for Pd
Hi IOhannes (and others) my apologies for the slow response, been settling into a new job here. If you are interested in helping out on that external, I would be happy to move it to pd-externals and not own the repo. If I new there was some interest and other people interested in hacking on it, I could find some time to give it some love. So uh, what exactly do I need to do to make this happen? Does it need a special license or anything? s7 is BSD licensed so I chose that to begin with. iain On Tue, Mar 19, 2024 at 5:10 AM IOhannes m zmölnig wrote: > On 3/17/24 06:14, Iain Duncan wrote: > > It occurred to me thinking further that really one doesn't need to know > > much about Scheme or Lisp, provided one is interested, as I didn't when I > > started!

It occurred to me thinking further that really one doesn't need to know

[PD-dev] Seeking co-maintainers for Scheme for Pd
Hello hackers, a couple of years ago I made Scheme for Pd, a sibling
project of my Scheme for Max external that allows scripting Pd (and Max) in
s7 Scheme. I'm now into a PhD and am (surprise, surprise) rather busy, but
there are some things that could be done with the Pd version that would be
interesting. In a nutshell, it's like a cross between Max's JS object (but
able to run temporally accurate code) and Common Music 3 (much of which it
can run, same Scheme interpreter).
For the initial release, I was only interested in solo development as it
was a master's project. This is a call to see if there are people
interested in joining on the project so I can bring it back to life. It
requires a fairly good understanding of writing externals in C and of
Scheme. It does not (yet) do DSP, only message stuff. There are a number of
recent developments in the Max version that would be neat to port over if
there is interest.
The project page is here:

[PD-dev] Question about right hand generic inlet creation
Hi folks, I'm not sure if I'm understanding the externals tutorial properly. It seems to me that it is saying that one cannot make a generic inlet past the first one, as in something that passes any incoming message to the same handler as an array of atoms. Is that the case or am I totally misunderstanding that?

[PD-dev] s4pd packaging: issues with [declare -path]
Hi folks, I'm still working on the packaging of s4pd with regard to finding scheme files, and am almost there, but having some weirdness with [declare -path]. It was recommended to me that I advise people in the docs to put a [declare -path s4pd] in their patches so that finding scm files would "just work". My understanding is that this would add the s4pd path to their file path, meaning that files in that dir should get found, just as if one had put it explicitly into the Pd path preferences. However, this doesn't seem to do that on MacOS. I run make install, and it puts my stuff in ~/Library/Pd/, so that there is a directory, ~/Library/Pd/s4pd, with all the files, at the same level as the external. But if I try to use a patch with an s4pd object and a [declare -path s4pd], the declare path appears to make no difference: I still need to go add ~/Library/Pd/s4pd to file preferences for the files to be found. Hopefully someone can clear up what is happening here, or my misunderstanding of what the declare is supposed to do. thanks! ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev

[PD-dev] another file path question for sp4d
Hi folks, I want to solicit opinions from the broader Pd dev community
before figuring out how to fix this bug report from Alex:
https://github.com/iainctduncan/scheme-for-pd/issues/15
His point was that a relative path didn't do what he expected, situation
- an s4pd object created as "sp4d scm/my-file.scm"
So this is what I think should happen for file searching, but will change
my mind if it is not in accordance with what users would expect. The
handling rules will be the same whether from a a "read {file}" message or
an arg to the object:
Proposed Rules:
- absolute paths - opened
- single file name paths:
- first look in the canvas directory
- then search all Pd paths
- relative path names (i.e. "s4pd scm/foo.scm"):
- search in the canvas directory
- do *not* traverse through all directories on the Pd search paths
Does that sound right? Or would the expectation be that it would search for
scm/foo.js on all the search paths?
Related, should it know how to do the right thing to convert unix style
paths on windows?
Please feel free to comment here or on the github ticket.

Re: [PD-dev] Packaging question for Scheme for Pd
Thanks, IOhannes, that sounds sensible. So in order to make it as
homogenous as possible between people who build from source and those who
install the package (as ultimately I would like this to be extension
friendly at the C level), do you think it would be best to just have the
scm files live in the same directory as the C files in the source? Or is
there some suggested approach when using pd lib builder to make this
simple?

[PD-dev] Packaging question for Scheme for Pd
Hi folks, I need some advice on what is the expected way for a package to
be laid out to avoid confusing users when they try to install. The
situation is that s4pd requires the external, and scm files that come in
the package. In development, I have those in an scm dir, and if you
build from source, that dir needs to be in the Pd search paths. For a non
developer user, I want install to be as simple as possible. Should a
downloadable package just put the scm files and external in the top level
of the package ('s4pd') so that this can simply be put in the Pd/externals
directory? I just need to know what "normal" is for a release package.
thanks
iain

[PD-dev] equivalent of Max attributes for optional keyword object args?
Hi folks, I want to add an optional argument for object creation time to Scheme for Pd to allow setting the starting heap size, which can dramatically lower garbage collector times. In Scheme for Max 0.3 I added the @heap attr. I'm not sure what the normal way to do this kind of thing is in Pd. The catch is that this arg needs to be optional (beginners shouldn't have to worry about it) and needs to be set at object creation time because you can't change the starting heap size after creating the s7 interpreter. So I'm somewhat reluctant to just add a 3rd integer arg. Suggestions welcome! thanks! iain ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev
Re: [PD-dev] plans for next Pd release
On the topic of minor message related improvements, I hope it's ok to chime in here, and I apologize if this has been hashed to death already and there are good reasons for the current state.. I'm doing a lot of making messages out of other objects to send to Scheme for Pd, and one thing I use all the time in Max is the right hand inlet for message boxes as a way to set the contents of a message. I'm curious whether there has been thought about adding that to Pd message boxes. It's a small thing, but very handy for the kind of patches I wind up making. thanks! iain On Tue, Jul 13, 2021 at 11:15 AM Miller Puckette via Pd-dev < pd-dev@lists.iem.at> wrote: > YEah, while I'm meessing with hovering I want ot do something like that > (but probably just graphical - I don't want to blow anyone out of his/her > seat > by accident :) > > On Tue, Jul 13, 2021 at 07:11:04PM +0100, Andy Farnell wrote: > > On Tue, Jul 13, 2021 at 10:22:17AM -0700, Miller Puckette via Pd-dev > wrote: > > > > > PS more ideas of mine (among many): > > > hot-reloading externs via a message to Pd > > > use a "unix binding" socket between Pd and pd-gui instead of localhost > > > generalize number/symbol box to allow displaying entire messages or > lists > > > > All good things, thanks Miller. > > While we're dreaming: tooltip style message inspection - when > > active, hover over a wire to see what's flowing or audition audio > > (maybe through compressor/limiter :) > > best, > > Andy > > > > > cheers > > > Miller > > > > -- > > > > ___ > Pd-dev mailing list > Pd-dev@lists.iem.at > https://lists.puredata.info/listinfo/pd-dev > ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev
[PD-dev] Question about prepping Scheme for Pure Data external for Deken?
Hi folks, I'm able to spend some time on Scheme for Pure Data again over the next couple of weeks, and just wanted to check on what I need to have done to make it easy to install through Deken. For Max, I had to have successfully compiled binaries for Mac, Windows 32, and Windows 64. Is it the same for Pd? I assume Linux users will get things either by compiling from source or a a linux package manager? thanks! iain ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev

Re: [PD-dev] s4pd help: portable uid-like thing in C?
Hi Christof, you are right, it was a bad idea, but the good news is that in the hours since I posted that I managed to get it to work properly. It's been a while since I did data structures manually in C... :-) I went for maintaining a double-linked list of clock_info structures that just stores them as they come in. If the interpreter is reset, or object freed, or we make a cancel-clocks request, that just gets walked with all clocks unset, freed, and the memory for the clock info nodes freed. In normal operation, no extra walking needs to happen as the (not cancelled) callback takes ownership of the pointers and cleans up as part of it's execution. The implementation could certainly be more elegant, but it seems to be robust (not sure I even need the double linking, but it helped me think about it...) I made a fuzzy tester that assaults the object with variable tempo'd delay requests, requests to cancel 1 delay, and requests to cancel all, and resets and I can't make it crash anymore, even recreating the object. Phew! Thanks for the help everyone. Will post to the list when the next cut is ready. iain On Sat, Jun 12, 2021 at 2:28 PM Christof Ressi wrote: > Hi, > > this is a bit of a XY question.

[PD-dev] More clock questions
I have a couple more clock/schedule related questions after rereading the comments from Miller and Seb. 1) Is the Pd clock scheduler only accurate to the ms or does it operate at higher than ms accuracy? (As in, if I wanted to role my own mechanism closer to what Seb did, how frequently should my master time go off?) 2) Miller made reference to the linked list of clocks that pd iterates through. Is that something I could access directly? (and if so, where would it live? 3) if anyone knows good books or online resources for learning more about writing scheduler related code, I'm all ears! :-) thanks iain ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev
[PD-dev] s4pd help: portable uid-like thing in C?
Hi folks, i'm wrestling away with the schedule functions for Scheme-for-Pd, and I think I can make things a lot more reliable if I let every instantiation (or restart) of the scheme interpreter have a uid of some sort so that on a reset we can just ignore clocks running out on a previous instance instead of trying to clean them all up with manual memory management. (which approach is giving me segfaults because I'm screwing something up) Can anyone tell me what a smart way of getting a unique identifier would be? It doesn't need to be unique across the world, just the local machine, so something that was seeded from system time would be fine.

[PD-dev] Scheme-for-Pd, how to release beta versions, call for testers
Hi folks, I'm only a few days away (I think!) from a first beta release for Scheme-for-Pd, and am wondering what I'm supposed to do for releasing to the early testers given I don't want to put it on Deken until it's had the tires well kicked... Things I need to sort - answers or pointers to where to read both appreciated: Is it pretty common that people know how to build or should I prepare a binary for OSX and Windows? If so, how is that normally bundled up? I need people to have external, the help patcher and also a set of scm files on their pd search path for it all to work. Is there anyone who would be interested in testing out building and running, both from zipped up packages and cloning and building? There's a pretty extensive help file, and everything in it should "just work".

Re: [PD-dev] using the PD filepath in an external?
Thanks Miller. Looking at that example, this seems to be a way to open and read in the whole file into C, which I could do, but the path of least resistance for me so far has been to pass the actual loading to s7. Is there a way to just get the full path for a file found from the Pd filepath? (if not, I suppose I'll read the file in and the eval_string on it or something...) thanks! iain On Wed, Jun 9, 2021 at 3:13 PM Miller Puckette wrote: > open_via_path() should do it.

[PD-dev] using the PD filepath in an external?
Hi folks, I tried to google this, but of course am swamped with results on how to load things in the patcher instead of what I'm looking for. Can anyone point me at how to use the filepath to load files in an external? In Max I have s4m find the fullpath for the bootstrap files and then load them up through s7s native load function with the fullpath. If anyone has an example of something similar for Pd, that would be lovely! thanks ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev

Re: [PD-dev] Creating delayed functions in Pd external?
Ah, ok. I also just realized (necessity being the mother of and all that) that I can probably be storing these on the scheme side too, as the actual function object is stored there anyway in a hash-table. Related: in Max they recommend using sysmem_newptr instead of malloc, is there a recommended cross-platform Pd replacement for malloc I should be using? thanks! iain On Sun, Jun 6, 2021 at 6:52 PM Miller Puckette wrote: > Well, Pd's own scheduler for clocks keeps them in a linked list and chases > down it to set and unset them.

Re: [PD-dev] Creating delayed functions in Pd external?
Thanks Miller. That brings up one more question.. ;-) In Scheme for Max, the way I do it is I keep a hash-table in C going with keys that are created on Scheme delay calls, so that one can cancel clocks by fetching them from the hashtable. In Max, there's a cross-platform hash-table implementation that I'm using. Is there something similar for Pd, or if not, is there an approach you would recommend for keeping a key-value store in C for the clocks by a symbolic key? I guess a good question might be if this is even necessary, given there can't be *that* many clocks scheduled for the future. And association list type thing might do just as well. thanks for the help, it's going well, now that I can finally work on it! ought to have a first alpha folks can play with in the next couple of weeks. iain On Sun, Jun 6, 2021 at 5:36 PM Miller Puckette wrote: > clock() is the only mechanism - for repeats, the easiest thing is often > to just re-use a clock() and re-set it each time it goes off (as in > the metro obejct).

Re: [PD-dev] Creating delayed functions in Pd external?
Ah fantastic, thanks. I was looking in pipe and not seeing it, but was probably just lost in other new details and not seeing the forest for the trees. :-) Couple of follow ups: - is there a separate facility for making a repeated callback (ie not one-shot), or does one just do both with clock? - is it safe to make clocks as we need them (ie during a method call, not necessarily at object instantiation time), or is this the kind of thing where for real time use one needs to make a clock pool and a pool manager and all that? thanks! iain On Sun, Jun 6, 2021 at 5:12 PM Miller Puckette wrote: > Yep, clock_delay() .

[PD-dev] Creating delayed functions in Pd external?
Hi folks, I'm hoping someone can point me in the right direction here. I'm porting Scheme for Max to pure data and I'm stuck figuring out how to get delayed functions going. In Max, the SDK has a facility to make register a callback to executed at some point in the future, a few different ways. Is there a Pd equivalent, and if so, could anyone point me at resources or code for it? I basically just need to be able to have a callback fire off at the right time with one argument, which can be void pointer to the rest of the stuff i want to get. thanks! iain ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev

[PD-dev] pd-lib-builder question (on osx)
Hi devs, I'm trying to get pd-lib-builder working, but I think my lack of C building experience has me stuck. I was able to get my empty helloworld working ok, but not managing to link in S7. My project has one C file, and needs to also include s7.h and build s7.c I've included my (not working) Makefile below. When I try the below s7 does get compiled, producing an s7.o file, but instead of static linking I get an s7.pd_darwin file with all of the S7 stuff (it's big) and a tiny s4pd.pd_darwin file. And the external tries to load an s7 function and fails. Any tips much appreciated! thanks, Iain My Makefile: # library name lib.name = s4pd # tried these too, to no avail #lib.setup.sources = s7.c #common.source = s7.c # input source file (class name == source file basename) class.sources = s4pd.c s7.c # all extra files to be included in binary distribution of the library datafiles = README.md # include Makefile.pdlibbuilder from submodule directory 'pd-lib-builder' PDLIBBUILDER_DIR=pd-lib-builder/ include $(PDLIBBUILDER_DIR)/Makefile.pdlibbuilder ___ Pd-dev mailing list Pd-dev@lists.iem.at https://lists.puredata.info/listinfo/pd-dev
Re: [PD-dev] implementing pools of clocks?
Ok cool. Thanks Miller, I will definitely look at the pipe code. Is there an external that has become the defacto version of a transport or anything like that? I would like to support common use cases in the most helpful way possible.

Re: [PD-dev] implementing pools of clocks?
Thanks Christof, that is helpful again, and also encouraging as it
describes pretty well what I've done so far in the Max version. :-)
I've enabled both one shot clocks (storing them in a hashtable owned by the
external) and periodic timers. The one shot clocks exist in both a
transport aware and transport ignorant format for working with and
quantizing off the Max global transport, and there are periodic timers for
both too. (The transport time stops when the transport is stopped, the
other is just a general X ms timer). I have also ensured the callback
handle gets passed back so that any timer or clock can be cancelled from
Scheme user-space. (is there such a thing as a global transport in PD?)
I was actually planning on something like you described in Scheme space: a
user defined scheduler running off the timers. I will look into priority
queues. I had one thought, which I have not seen much, and was part of the
reason I was asking on here about schedulers. I would like to ensure the
user can run multiple transports at once, and hop around in time without
glitches. I was thinking that instead of using just a priority queue, I
would do something like a two stage structure, perhaps with a hashmap or
some other fast-read-anywhere structure with entries representing a time
period, and holding priority queues for each period. This would be to
enable the system to seek instantly to the bar (say) and iterate through
the queue/list for that bar. Wondering if anyone has used or seen this type
of pattern or has suggestions? Basically I want to make sure random access
in time will work ok even if the number of events in the schedule is very
high, thus allowing us to blur the lines between a scheduler and a full
blown sequencer engine. Thoughts, suggestions, and warnings are all welcome.

[PD-dev] implementing pools of clocks?
Hi folks, I'm working on an external for Max and PD embedding the S7 scheme interpreter. It's mostly intended to do things at event level, (algo comp, etc) so I have been somewhat lazy around real time issues so far. But I'd like to make sure it's as robust as it can be, and can be used for as much as possible. Right now, I'm pretty sure I'm being a bad real-time-coder. When the user wants to delay a function call, ie (delay 100 foo-fun), I'm doing the following: - callable foo-fun gets registered in a scheme hashtable with a gensym unique handle - C function gets called with the handle - C code makes a clock, storing it in a hashtable (in C) by the handle, and passing it a struct (I call it the "clock callback info struct") with the references it needs for it's callback - when the clock callback fires, it gets passed a void pointer to the clock-callback-info-struct, uses it to get the cb handle and the ref to the external (because the callback only gets one arg), calls back into Scheme with said handle - Scheme gets the callback out of it's registry and executes the stashed function This is working well, but I am both allocating and deallocating memory in those functions: for the clock, and for the info struct I use to pass around the reference to the external and the handle. Given that I want to be treating this code as high priority, and having it execute as timing-accurate as possible, I assume I should not be allocating and freeing in those functions, because I could get blocked on the memory calls, correct? I think I should probably have a pre-allocated pool of clocks and their associated info structs so that when a delay call comes in, we get one from the pool, and only do memory management if the pool is empty. (and allow the user to set some reasonable config value of the clock pool). I'm thinking RAM is cheap, clocks are small, people aren't likely to have more than 1000 delay functions running concurrently or something at once, and they can be allocated from the init routine. My questions: A) Am I right, both about being bad, and about clock pre-allocation and pooling being a decent solution? B) Does anyone have tips on how one should implement and use said clock pool? I suppose I should probably also be ensuring the Scheme hash-table doesn't do any unplanned allocation too, but I can bug folks on the S7 mailing list for that one...
