[ pure-data-Feature Requests-1084656 ] Add proper "delete" or "clear" message to pd-[patchname]

Bogart (bbogart) Assigned to: Nobody/Anonymous (nobody) Summary: Add proper "delete" or "clear" message to pd-[patchname] Initial Comment: For those of us doing dyanmic patching (where a patch constructs itself) It would be really handy to delete the contents of a subpatch without it opening! Currently if you want to delete the contents of a subpatch called "array" you need to send this message: ; pd-array vis 1, selectall, cut And the "array" subpatch must open for the delete operation to work. If you omit the "vis 1" message the contents of the subpatch are not deleted and PD prints a message about the patcher not being found like: "invalid command name .x442b65.m.edit" ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478073&aid=1084656&group_…

Windows GUI question
by joerg piringer 11 Dec '04

11 Dec '04

i am trying to write an external to open a new window similar to a gemwin. i basically copied the gemwincreatent file contents to my external. the problem is that once i opened the window it doesnt react to messages. the windowproc only gets called when i do it manually via updatewindow for example. it does not react to key presses or mouse events. what could be the problem? i also tried to create my window with mfc but that crashes pd. when i debug the mfc i seems that there is no afxthread (whatever that could be). another question: is it possible to draw directly on the patcher window? without tcl/tk? best joerg -- http://joerg.piringer.net http://www.transacoustic-research.com http://www.iftaf.org http://www.vegetableorchestra.org/

EEK! I think I spoke too soon: I just tried running a rradical patch and crashed due to multiple definitions: dyld: /Users/tigital/puredataDev/pd-0.38-0test10/bin/pd multiple definitions of symbol _grow_nodata /Users/tigital/Desktop/pdPatches/pixelTANGO-pre-release-v0.1/externals/ prepend.pd_darwin definition of _grow_nodata /Users/tigital/puredataDev/externals/mixed/bin/tosymbol.pd_darwin definition of _grow_nodata Program received signal: "SIGTRAP". ...so, I guess this means we either need to recompile all externals with -two_level_namespace, or go back to the drawing board? jamie

[ pure-data-Bugs-1082938 ] sys_load_lib() on OSX too limited?
by SourceForge.net 10 Dec '04

10 Dec '04

Bugs item #1082938, was opened at 2004-12-10 06:23 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1082938&group_… Category: puredata Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: sys_load_lib() on OSX too limited? Initial Comment: ...externals are loaded and linked as NSModules, but it seems that we may be limiting ourselves by using the NSLINKMODULE_OPTION_PRIVATE flag? This flag came to my attention while I was trying to compile pdp2gem.pd_darwin, which acts as a bridge between pdp and gem: ie. it requires linking to symbols from both libraries, which should be done at module load time...this is not possible with the PRIVATE flag, but it does work with out it... ...so, I'm wondering if there's a general rational behind this that isn't obvious, or if we can just go ahead and remove it? Preliminary testing has not showed any obvious problems with multiple libraries... ...here's the relevent docs from xcode: options An unsigned long value. Pass one or more of the following bit masks or NSLINKMODULE_OPTION_NONE to specify no options. NSLINKMODULE_OPTION_BINDNOW The dynamic linker binds all of the undefined references immediately, rather than waiting until the references are actually used. All dependent libraries are also be bound. NSLINKMODULE_OPTION_PRIVATE Do not add the global symbols from the module to the global symbol list. Instead, you must use the NSLookupSymbolInModule function to obtain symbols from this module. NSLINKMODULE_OPTION_RETURN_ON_ERROR If an error occurs while binding the module, return NULL. You can then use the function NSLinkEditError to retrieve information about the error. Without this option, NSLinkModule calls the linkEdit error handler you have installed using the NSInstallLinkEditErrorHandlers function. If you have not installed a link edit error handler, NSLinkModule prints a message to the standard error stream and causes a breakpoint trap to end the program. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1082938&group_…

I think this has to be solved in the pd internals first, in the Okay - you are right :( ! > Let me guess: his name is Mario ?

Yep, I also thought about this that way. The IDs of the objets don't have to be numbered (in the XML format) - they could only be strings. But, of course, then the problem is, that all the objects must be registered somewhere in pd!
