Yes we should probably have a look at method trailer with you but first we should build the infrastructure and test it. Stef

[Pharo-project] Weird OB accept behavior

by Schwab,Wilhelm K

I am using a 1.1.1 image with SystemBrowser defaultOpenBrowser OBSystemBrowserAdaptor I am debugging some code that I have not used for a while, so a few growing pains would not be a surprise. What DOES surprise me is the following: (1) select #plotFrom:to:using:keepGoing:plots: and accept the code; no errors are reported; fair enough (or is it?). (2) edit the source (even just adding a harmless new line) and accept, and the compiler (correctly, it appears) complains that arguments are already defined. I suspect the arguments are indeed stomping on instance variables that I added during the past year, and that confusion is the source of some seriously strange looking behavior. The point is that accept is apparently doing nothing or failing silently until I actually edit the source. I greatly prefer the error messages to silence; I assume the silence is related to a desire to get code loaded intact rather than having MC bark mid-load?? Bill

[Pharo-project] Alien + Cog VM

by Ken Treis

What's the status of Alien in the new Cog VM? I was able to load Alien into Pharo 1.1.1 running Cog, and some simple callouts worked (e.g. `CRLibrary libraryVersionString` in CairoGraphics. But every callout with arguments failed in primFFICallResult:. Alien works perfectly for me in Pharo 1.1 using JMM's VMs when I load the Pharo 1.1 version from ConfigurationOfAlien, but I admit I haven't tried 1.1.1 in this arrangement. Is there something that's changed in Cog's Alien primitive implementation? -- Ken Treis Miriam Technologies, Inc.

Or there are some better way to install it? Yes, the version in MetacelloRepository isn't working for any combination of Pharo and Magma versions, so I proposed: http://lists.squeakfoundation.org/pipermail/magma/2010-August/001587.html You can use that for installing it in a Pharo image. Note that with the new Metacello features that Dale released a few days ago this will be obsolete and more likely the MetacelloRepository will work again. For the time being, use the directions of the previous link, and when I have a little time to update the Magma Configuration with Dale's features, I will announce it on this list.

[Pharo-project] Loading Magma in Pharo 1.1

by Giuseppe Luigi Punzi

Hi all, I get a warning about dependencies of Flaptab installing Magma with: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfMagma'; load. (Smalltalk at:#ConfigurationOfMagma) project latestVersion load: 'Server'; load: 'Client'. Is safe installing anyway? Or there are some better way to install it?

[Pharo-project] VM Plugins that are important for performance?

by Stefan Marr

Hi all: >From your experience, what are the important VM plugins to gain a snappy and responsive Pharo image. Stef mentioned the Font plugin, but will this improve the user experience or is it just nice to have to support different kinds of fonts? The reason for my question is the 'performance hit' I have to take with the RoarVM for the moment. So, if there are things typically done in plugins which now running in Smalltalk on the RoarVM, then I guess I could benefit by including those plugins.
