Re: [Pharo-users] [ANN] Headless support for Cog Cocoa VM

by Sven Van Caekenberghe

Hey Mariano, Work perfectly for me (10.8.2) : $ ./CogVM-release-noflash-noArgs.app/Contents/MacOS/CogVM Pharo-20472.image eval 'ZnServer startDefaultOn: 9999. [ (Delay forSeconds:1000) wait ] repeat.' Thanks, a useful addition !

If you don't want headless, put it to false or don't even put the key. If you don't set LSBackgroundOnly to 1 but send -headless, the VM will still be headless but you will see a little flash.

You should run the image with something like RFB or Seaside or whatever you can and then confirm if it is working even if you are headless. As a matter of testing, I saved an image with seaside running in the port 5555. You can get both, this Seaside image and the VM with headless from: https://www.dropbox.com/sh/r7qk49bxywk2xce/6N7-fdyx6V > So if you run the VM headless with that image and go to localhost:5555, you should see that Seaside is running. > > I would appreciate if you can test it.

[ANN] Headless support for Cog Cocoa VM

by Mariano Martinez Peck

Hello there, For a long time, Pharaoers and Squakers have been asking for headless support in the Cocoa VMs just as we have with Carbon VMs. Carbon is becoming a legacy framework so people needed this. I wanted to thanks Square [i] International <http://www.square-i.net/> for sponsoring me to implement such a support. Not only have they sponsored the development but they have also agreed to release it under MIT license for the community. This headless support will be included in the official Pharo VM and will be, therefore, accessible to everybody. The project is not yet finished but I do have a demo/prototype that I wanted to share with you so that you can test it and give me feedback. This VM should only work starting at OSX 10.6. *How to use it?* Basically it works this way: to have headless, just edit the Info.plist and set the flag LSBackgroundOnly to 1 (add the key if it is not present): <key>LSBackgroundOnly</key> <true/> When doing this, you don't even need the -headless anymore since, setting LSBackgroundOnly to 1, will cause the same effect (being the flag almost mandatory). If you don't want headless, put it to false or don't even put the key. If you don't set LSBackgroundOnly to 1 but send -headless, the VM will still be headless but you will see a little flash. If this flash bothers you, then set the flag. I am trying to get a way to avoid the "flash" while also avoiding to set LSBackgroundOnly to 1, but I still couldn't find it. Anyway, I think we can live with the current situation. *How to test it?* You should run the image with something like RFB or Seaside or whatever you can and then confirm if it is working even if you are headless. As a matter of testing, I saved an image with seaside running in the port 5555. You can get both, this Seaside image and the VM with headless from: https://www.dropbox.com/sh/r7qk49bxywk2xce/6N7-fdyx6V So if you run the VM headless with that image and go to localhost:5555, you should see that Seaside is running. I would appreciate if you can test it. And please let me know in which version of OSX you tried. Of course, the more of you who can test it, the better. Notice that this VM was compiled with LLVM GCC 4.2 and it may have some problems in older OSX versions (but I think it shouldn't).

Do you know if HTML5 would be handled as ill-formedness? Apart from that I'm interested if kind of a document model is emitted or what it does. Well, I'll have a look. thanks, Norbert

Not sure if it works in Pharo etc, but this one was very good earlier at dealing with baaad HTML: http://www.squeaksource.com/htmlcssparser.html I used it in a scraper robot successfully. regards, GÃ¶ran
