[Glass] Basic questions regarding GemBuilder for Smalltalk, GemTools, and tODE

[James Foster]

Hi Mariano,

Others have given good answers, but I'll offer my input as well! 

See http://programminggems.wordpress.com/2013/10/01/jade/ for a blog post and https://www.youtube.com/watch?v=dnRB5rBbkiI for a screencast showing how to load Seaside 3.0 and Magritte3 into GemStone/S 3.1.0.4. Also this gives a demo of Jade, a GemStone/S IDE for Microsoft Windows that has been in development and use for about 10 years and has good network performance.

But there isn't any GemBuilder for Pharo (only VW and VA). I also thought part of GemBuilder was to map certain kernel classes of the client language to GemStone, to retrieve objects from GemStone into my smalltalk client vm..etc.

That means that GemBuilder is optional and I could use Topaz only. If I use Topaz directly, it means that I don't need any GemBuilder at all for Pharo? If true, how then it happens that "mapping of certain kernel classes" that I read somewhere?  in other word, why would I not need a GemBuilder for Pharo but do need it for VW and VA? Just because there is no UI and all we have is seaside running? And if I run Seaside in VW then I don't need GemBuilder for VW?

I guess this is not a very big problem because I would use that image only to load my code into GemStone and maybe for other small issues. Still, I will continue developing my app in Pharo 2.0 and I will keep having my ConfigurationOfXXX with the proper load for GemStone. Right?
