[Pharo-project] example preferences startup script Re: 1.4 - better from Jenkins

by Ben Coman

I just realized that clearing up those two ShouldBeImplementeds from DosFileDirectory did not really prove that startup preferences worked on MS Windows. So I found the StartupLoader class>>example method and did get... 'I should only be displayed once' ...one time only and do get... 'I should be displayed each time' ...each time I start Pharo. So its good :) !! However the 'each time' also dialog comes _every_ time I save the image. Is that desired behaviour? or is it just not finished yet? btw, I was a little confused at first by how to use StartupLoader class>>example. Initially I copied the whole text of that method into pharo/1.4/startup.st and the started the image - and the 'once' and 'each time' messages did appear - but also a number of errors. It wasn't until I notice and wondered about the created file pharo1.4.st that I worked out that 'StartupLoader class>>example' should have just been executed rather than manually copied.

[Pharo-project] move to gemstone!

by Camillo Bruni

again as squeaksource was down today I think everybody should move their projects to gemstone... as mariano pointed out in his blog this is fairly easy to do if you have a configuration: conf := #ConfigurationOfSoup. ss := 'Soup'. ss3 := 'soup'. gofer := Gofer new package: conf. gofer copy squeaksource: ss; load. project := (Smalltalk at: conf) project latestVersion. project packages do: [:spec| gofer package: spec name. ]. gofer copy squeaksource: ss; fetch. gofer copy url: 'http://ss3.gemstone.com/ss/', ss3; push. best cami

So. I think it is useless to try extending fuel with metadata. if people want to have metadata, they should make it by own, in the way they see fit. I think fuel should do one thing : serialize/materialize stuff. Lets not turn it into "i can do everything to please you" library. -- Best regards, Igor Stasenko.

Btw, javier i cannot load your package to check what you did: This package depends on the following classes: NBXLibConstants You must resolve these dependencies before you will be able to load these definitions: NBGLXContextDriver supportsCurrentPlatform createContext: On 10 February 2012 19:34, Igor Stasenko <siguctua(a)gmail.com> wrote: > On 10 February 2012 19:19, Lawson English <lenglish5(a)cox.net> wrote: >> Is that code even ready for consumption? >> >> I was told that until there is a new ConfigurationOfNBOpenGL ready, to not >> load the new packages. >> > > you could try :) > > but this is what i working on now (slowly integrating the parts of > Javier's code, > because not everything which he did i like ;) > > >> L. >> >> >> On 2/10/12 10:12 AM, Javier PimÃ¡s wrote: >> >> I'm trying to create an OpenGL context on linux but glxChooseVisual fails. >> Maybe there's someone there experienced with this that can help. >> >> The code I'm trying is: >> >> display := NBXLibDisplay open. >> window := display defaultRootWindow. >> visualInfo := NBXLibVisualInfo fromPointer: (gl chooseVisual: display >> screen: display defaultScreen attributes: {GLX_RGBA.
