Re: [Pharo-users] Invoking external processes/IPC

by Marcin Tustin

Following Mariano's advice, I just tried installing Alien (using Pharo-1.1-11406-rc3 with the Seaside RC3 image; this is a sane version, not affected by previous package loading problems). I loaded ConfigurationOfAlien (ConfigurationOfAlien-KenTreis.26) using Monticello, then executed ConfigurationOfAlien loadCore (as per the instructions). That resulted in an error: 'SystemDictionary>>recreateSpecialObjectsArray appears incompatible' raised from ensureInSpecialObjectsArray. The cause appears to be that Alien wants to be in the special objects array at 53, but the array is created to be size 50. Proceeding through the error results in the predictable subscript out of bounds error. running loadCore once more (second time) does the same thing. Doing it a third time results in a message not understood 'initScannerForTokenization' from Parser>>ParseSelector:. Any ideas?

funny idea Symbol vs. Selector

by stephane ducasse

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Mariano, Thanks for this. I belive CommandShell depends on OSProcess. I am using windows, so I guess neither is a runner anyway. I'll try FFI/AlienFFI.

Re: [Pharo-users] Freetype package breaks preferences browser?

by Marcin Tustin

Thanks. I was under the impression from SqueakSource that the plugin needs to be compiled. Is there another site for the project that is more up-to-date/helpful/official? Given the screwy results once I loaded my changed version, I'm hesitant to submit them.

Which OS are you? because I think OSProcess is not working on Windows. And I also think there are binaries for it, so you don't need to generate .c from VMMaker neither compile c code to binary.

I guess you don't need this package if you won't compile the plugin by yourself. Second, Pharo 1.0 or Pharo 1.1 ? I guess Pharo 1.1.

Further to the below, I tried just fixing all the instances of _, and resulted in #messagenotunderstood 'or' exceptions being generated every second or so, until the VM locked up.
