garbled list digests?
by Dan Wilcox 29 Mar '16

29 Mar '16

Is anyone using Mac Mail having issues with MIME digests from the pd-list? Occasionally, a digest comes in garbled and unreadable for me. I switch to plain text but quickly missed the attachment handling in the html/MIME messages. -------- Dan Wilcox @danomatika <https://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Hello Dan, I get plaintext digests and I haven't noticed any inconsistencies, although I admit I haven't paid too close attention to the formatting. Perhaps that's an option? Although you do miss out on the benefits of MIME... Derek ===================== Derek Kwan www.derekxkwan.com

Re: [PD] can signal inlets that aren't the main inlet have float or message methods?

Thanks, John, I'll take a look myself and yeah, I'm not super-optimistic either. There are calls to class_addcreator for "scope~" and "cyclone/scope~" but yeah, "Scope~" is a weird one... Derek ===================== Derek Kwan www.derekxkwan.com

utf-8 symbols in OS X
by Roman Haefeli 28 Mar '16

28 Mar '16

Hey all I was trying out a patch on OS X 10.10 with Pd 0.46-7. The patch contains some cnv objects with labels containing utf-8 geometric shapes (namely ▶ and ●). The symbols are displayed correctly on Windows and Linux, but not on OS X. Instead, they show a crossed box (like [X]). The same symbols are displayed in OS X' Terminal app or TextEdit app. Maybe it's an issue with the font in Pd? The problem not only appears in Pd canvases, but also in the Pd console which uses a different font. The decoration of the zexy greeter also shows those boxes instead of white hearts (♡). Roman

Sorry about the huge attachments. I just read the netiquette page and will use links next time.

can signal inlets that aren't the main inlet have float or message methods?
by Derek Kwan 27 Mar '16

27 Mar '16

Hello, Thanks for pointing me to the concept of proxy inlets. I've tried to implement a test external using this code: http://puredata.info/Members/mjmogo/proxy-example-for-pd.zip/view In the linked code, they're basically making another class of type t_proxy: typedef struct _proxy { t_pd l_pd; // if you want to maintain a pointer to your main class, // if not, besure to change the 'init' function void *yourclass; } t_proxy; This struct is declared as a member of the main class's struct: typedef struct _yourclass { t_object x_obj; t_proxy pxy; } t_yourclass; and the new inlet is created in the "new" method of the main class (yourclass_new) but with the destination pointing to the proxy rather than the main class. This is done via: inlet_new(&x -> x_obj, &x -> pxy.l_pd, 0, 0); with no selectors passed. However, this only makes a control inlet. Trying out: inlet_new(&x -> x_obj, &x -> pxy.l_pd, &s_signal, &s_signal); makes a signal inlet, but it seems like the signal values are only accessible via the main class's dsp/perform methods and not via the dsp/perform methods i tried to make for proxy (I call CLASS_MAINSIGNALIN in both the setup of the main class and the proxy class). That's not a huge deal, but I also declared a float method within proxy's setup via class_addfloat(proxy_class, (t_method)proxy_post); where proxy_post just posts to the pd window whenever it receives a float and this method only seems to be called when I declare the inlet the first way with no selectors (when it's a control inlet) and not the second way passing the signal selectors (making it a signal inlet). In the second way, the float just acts like a substitute for a signal (which is what I don't want). My main goal is to have a second signal inlet that can also accept floats not as a substitute for a signal but calls a separate method. Any ideas? Thanks! Derek -- www.derekxkwan.com

can signal inlets that aren't the main inlet have float or message methods?
by Derek Kwan 26 Mar '16

26 Mar '16

Hey y'all, I'm actually the one that needs this, I've been working with Alexandre on updating Cyclone. If further info is needed, the method I've been trying to use is inlet_new. The part of documentation that seems to drive the nail in the coffin is this bullet-point: "It is not possible to add methods for more than one selector to a right inlet. Particularly it is not possible to add a universal method for arbitrary selectors to a right inlet." found on this page: http://pdstatic.iem.at/externals-HOWTO/pd-externals-HOWTOse8.html#x10-41000C -------------------------------- www.derekxkwan.com

strange result with netsend/netreceive
by Jack 26 Mar '16

26 Mar '16

Hello, when i send a float '1000001' with 'netsend', 'netreceine' get '1000000'. Is it a normal behavior ? Configuration : Pd 0.46.5 Ubuntu 15.10 ++ Jack PS : i find a workaround by sending the number as symbol.

Edit Pd file to change coordinates. pdlua or other language?
by João Pais 25 Mar '16

25 Mar '16

Dear list, I wanted to edit some Pd files so that I can change the coordinates of *some* lines. For example, if in a pd file there is the content: #N struct 1164-element float x float y float nr float index float nr-show float tick-show; #N canvas 168 80 670 664 gui 0; #X obj 186 548 textfile; #X obj 167 328 openpanel; #X obj 395 878 delay; #X obj 474 838 expr 60*$f1/$f2*1000; #X msg 166 668 stop; #X obj 293 207 hradio 17 1 0 6 \$0-instructions \$0-colord-i empty 0 -6 0 8 -134268 -1 -1 0; I wanted: a) in the lines beginning with "#X obj", to change the 2 fields afterwards to a general value I'll give in the command (e.g. all lines are changed "#X obj 100 100 ...") b) to exclude from this operation the line numbers I supply, preferably in an expression such as "5 10 20-30" etc. To give an example, with the command "100 100 4-6", the text above would be changed to #N struct 1164-element float x float y float nr float index float nr-show float tick-show; #N canvas 168 80 670 664 gui 0; #X obj 186 548 textfile; #X obj 167 328 openpanel; #X obj 395 878 delay; #X obj 100 100 expr 60*$f1/$f2*1000; #X msg 166 668 stop; #X obj 100 100 hradio 17 1 0 6 \$0-instructions \$0-colord-i empty 0 -6 0 8 -134268 -1 -1 0; where all lines starting with #X obj were change, except for lines 4-6. Further numbers or ranges after 4-6 would indicate other lines to exclude from the replacement. I know this isn't a task which can be done in Pd, but much better in a language such as lua or python. As I don't know any of these languages, I would appreciate some guidance on how to start, and maybe I could myself continue the work. Preferably I would like to try it in lua, so that I could process it in pdlua. But any suggestions are welcome. Except using grep, as I only have access to an ms-dos console, no bash or similar ones. Thanks, jmmmp
