Doru, "/Now pay attention class categories will not exist in the future./" I already know about system categories (categories of classes) and method categories within a class. I understood you to mean system categories. What are class categories and why will they be removed? --Trygve On 21.09.2014 15:36, Tudor Girba wrote: > What do you mean? > > Doru > > On Sun, Sep 21, 2014 at 2:42 PM, Trygve Reenskaug <trygver(a)ifi.uio.no > <mailto:trygver@ifi.uio.no>> wrote: > > > On 20.09.2014 14:51, stepharo wrote: >> This is cool I blog about it. >> Now pay attention class categories will not exist in the future. >> >> Stef > Any ref to this development? > > > > > -- > www.tudorgirba.com <http://www.tudorgirba.com> > > "Every thing has its own flow"

Seeing that Sven's prebuilt Reddit image has Glorp and PostgresV2, today I set about to integrate NBSQLite3 into it. After spending an afternoon mucking around with the dialect and database interfaces, I think it doesn't look *too* challenging to add new drivers. With a small class, I hooked Glorp up with NBSQLite3 and just under half of the 887 tests passed on the first run. Probably the majority of these tests have nothing to do with talking to actual databases! :-) But for sure an SQLite database was created and worked on by the tests. I did bypass one level of indirection used with PostgresV2. Let's see whether the NBSQLite3 interface needs this additional indirection eventually. Will post again when I go somewhere with this.

Not much of a script as such. Put your Pharo image, changes and sources files in your home directory. create/edit a file called .xinitrc containing only "exec pharo-vm-x" (without quotes) within your home directory. Start the X session by issuing "startx" at the command line, and the GUI should be up with Pharo as the only application, no need for even a window manager. Next, just set the Pharo session to use full-screen mode by bringing up the "World" menu inside Pharo, go to the "Windows" sub-menu, and choose "Toggle Full Screen mode", and voila, you have a Pharo full-screen session, as if it's your GUI, remember to save the changes when you quit the Pharo session (which will drop you back to your *nix shell). The next time you issue "startx" within your home directory, the GUI presented would be Pharo. :) Still working on making Pharo the only shell running directly atop the Linux kernel with X as the windowing system, yeah, tried Linux FB, failed.

It already does. But the RPi is not that small by some definitions (512MB RAM, 4GB HD, 32-bit, full linux), while for others it might be a baseline. > ~Mayuresh > > > On 2014-09-20 09:45, S Krish wrote: >> try the TCL + Pharo stuff.

I have built Linux systems which fit in 8MB of disk space (along with the GUI). Google around for "NevyOS". Building a tiny Linux system isn't what worries me, it's the probable high resource consumption of Pharo which is scary. Would Pharo be able to run in the limited compute resources offered by low cost computers like the Raspberry Pi? ~Mayuresh On 2014-09-20 09:45, S Krish wrote: > try the TCL + Pharo stuff.

try the TCL + Pharo stuff. It is simple and easy to hook up. Tiny Core gets it down to around 20 MB for a bare bone linux + Pharo can be similar to Android if one goes down the path.
