Destructive copy in #replaceFrom:to:with:startingAt:
by James Foster Aug. 10, 2019

Aug. 10, 2019

After many hours of debugging Iâve finally discovered that Pharoâs implementation of #replaceFrom:to:with:startingAt: does not make any check for overlapping regions to avoid destructive operations. | bytes | bytes := #(1 2 3 4 5 6 7 8) copy. bytes replaceFrom: 4 to: 7 with: bytes startingAt: 1. bytes "#(1 2 3 1 2 3 1 8) in Pharo" "#(1 2 3 1 2 3 4 8) in GemStoneâ Essentially, Pharo has taken a memcpy() approach rather than a memmove() approach (https://fresh2refresh.com/c-programming/c-interview-questions-answers/what-… <https://fresh2refresh.com/c-programming/c-interview-questions-answers/what-…>). While it isnât the implementation I would choose, at least now I know! James Foster

Catalogue Browser - Bootstrap 4
by Jeff Gray Aug. 9, 2019

Aug. 9, 2019

So Bootstrap 4 has just come on to my radar - thanks Esteban. I usually look for things in the Catalogue Browser. Is that no longer the place to go? Do I need to get into searching Git instead? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Pharo 1.4 porting
by dario.trussardi65 Aug. 8, 2019

Aug. 8, 2019

Ciao, i have a old Pharo1.4 Latest update: #14445 run on MacBook with Mac OS X 10.7.5 ( Lion ). In this system the Pharo image run fine. I copy the relative folder on a MacBook with Mac OS X 10.14.6 ( Mojave ). Now in this system, when i double click on the relative folder icon the system open a empty black foreground window. The System Application don't report any Pharo application. I need to register - install a Pharo application? In this last system i also copy a Pharo GemTools-1.0-beta.8.7-3101 folder. It run without problem. Any consideration is welcome. Thanks, Dario

A Canticle for Smalltalk

A big fan of my work created this rogue video: https://drive.google.com/file/d/1opveHaukFK8WbQ8wg8b14wuKJsjoOZfO/view I appreciate the homage, but I can't take credit for it. It's really quite beautiful, though. I'm using it as part of my evangelism.

Can I control the location of the PharoDebug.log
by Dale Henrichs Aug. 7, 2019

Aug. 7, 2019

It appears that the PharoDebug.log can be dropped into the directory from which a Pharo image is launched ... I would have expected it to be dropped into the local directory, but that does not appear to be the case ... I've looked in the Settings Browser and there does not appear to be a way to influence the location of the PharoDebug.log. I am currently using the `st` command line handler if that is important. I've googled for PharoDebug.log to no avail. Any help will be appreciated, Dale
