In any case, the DBusPlugin is a wrapper for libdbus so I'd expect it to just work ... there is a DBus port for Windows; Emacs support it, for example. I don't know about other platforms. Stef |

MIDI plugin [was: Google Summer Of Code 2010 news!!!]

In reply to this post by Stéphane Rollandin
actually I have not made myself clear about the MIDI support:
currently I'm developing a musical composition framework on Windows, where the MIDIplugin works fine. on linux, there is no MIDIplugin built in the VM so I have this test: | plugins | plugins _ (SmalltalkImage current listBuiltinModules, SmalltalkImage current listLoadedModules) collect: [:pn | (pn findTokens: ' ') first asSymbol]. self assert: (plugins identityIncludes: #MIDIPlugin). ... which fails in linux, and I would like to have it green, and use the MIDIplugin exactly as in Windows. is this possible now ? is it possible from the code you gave me ? best, Stef |

But be aware that your test is faulty. #listLoadedModules only lists loaded plugins and does not find available external plugins. You should remove #listBuiltinModules from your test, and ensure the plugin was loaded before (by calling any primitive in that module). - Bert - |

thanks, I will fix it. still, my question remains: can we at the moment have a MIDI support in linux ? like, just be able to use SimpleMIDIPort ? AFAIK this has been missing for years. regards, Stef |

I don't know. Try it. Report back if it loads the plugin, and if it works. > AFAIK this has been missing for years. Interest has been low. But the ALSA MIDI support was added 3 years ago and nobody much cared. If you really care, dig into the C code and make it work - the VM maintainers happily accept patches. :) - Bert - |

Stef, I don't know the status of MIDIPlugin support on Linux but I can tell you that the plugin does compile, and I think that it is distributed as a builtin plugin in Ian's latest VM at http://squeakvm.org/unix/. I'm afraid that I know very little about MIDI, and I don't have any actual MIDI devices to test on (*), but if you (or someone else) are in a position to do the testing, perhaps we can collaborate to get it working. I think that this plugin was done originally for Windows, so it might be necessary to do some work mapping it properly to device names on Linux. We did something like this recently for the SerialPlugin to make it work with USB serial devices, and I'm sure it would be possible to do something similar for MIDI if that is the issue. Dave (*) Actually maybe I do have such a device, I'll have to go read the manual and see if I can figure out what it does. |

Report back if it loads the plugin, and if it works. oh, it doesn't. there is no MIDI support in the linux VM, I have already said so a few times now, let's say it's the last time I say it :) > If you really care, dig into the C code and make it work - the VM maintainers happily accept patches. :) no, I won't, sorry, it's not trivial and I have no experience in that domain. cheers, Stef |

hi,
thanks for your help ! actually no special hardware is needed to test the MIDI plugin, packages timidity and pmidi are enough Timidity is a soft synth; it can be started in server mode with command timidity -iA -B2,8 -Os1l -s 44100 now we have a list of available MIDI ports with command pmidi -l in my system this lists 6 ports. one is enough for testing: in a Squeak workspace, evaluate SimpleMIDIPort primPortCount I get 0, because the primitive failed. there is indeed a so.MIDIPlugin file in the VM library folder, but to my eyes it does not seem to work. any help appreciated... this is with the latest VM, 3.11.3-2135 best, Stef |

In reply to this post by Gilad Bracha
the question is, do you have projects to be part of GSoC Gilad ?
If true, send me the title of the project, a description and if possible, titles as "Technical Details", "Benefits to the Student" and "Benefits to the Community". The deadline is....2 or 3 days :) Ahh each project needs a mentor. Those projects without mentors will be discarded. The same mentor cannot be in more than one project.

OK, I'll have a look at it. Thanks for the pointers. I tried running "pmidi -l" on my laptop, and get this: lewis@linux-6xfc:~/squeak> pmidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0 So that probably means I have a midi device on my sound card. I guess that should be all I need to test the plugin, right? Dave |

I think this project could be a good idea for GSoC. As I said, I would love if it (optionally at least) could not to block the complete VM while a function is being called. I would also love what you said: parse .h of libraries and automatically create the wrapper for Smalltalk. At least create the invocations to the functions, and map the structures to objects... We need to write a title, a little description and if possible titles like "technical details", "benefits to the students" and "benefits to the community". If you are interested please send it to me and I add it to the list. We also need a mentor (and a student, of course)...anyone is willing to do it ? Cheers Mariano |

I'm all for it, and hope that John or Eliot can mentor. Datapoints I'll add:
There is some support for parsing C headers in the Newspeak system. Aliens have been ported to Strongtalk as well as Squeak.
Finally - what licensing would apply if GNU Smalltalk were used? GPL is a big problem. Even LGPL elicits an immune response in a lot of commercial contexts. Is there a GSoC policy on this?

Yes, as you can read here: http://socghop.appspot.com/document/show/gsoc_program/google/gsoc2010/faqs#licenses it says:
That depends on your mentoring organization. All code created by student participants must be released under an Open Source Initiative approved license. It's also extremely likely that your mentoring organization will have a preferred license(s) and that you will need to release your code under the license(s) chosen by that organization. And as you can read in the link, LGPL seems to be accepted...so, from the GSoC point of view there is no problem with the license. Cheers Mariano

Well I do not know anybody writing code under LGPL in Smalltalk. So this is an issue. I think that having a license mess will not help. So we do not care about the fact that the project use a apporved license, we care that people can/will use it afterwards. So LGPL is not a good idea.
