A fast Transcript
by Eliot Miranda May 11, 2015

May 11, 2015

Hi Juan, I see that your new transcript is indeed much faster but is also not editable. I wonder if it would be possible to have the best of both worlds and arrange that, when active, the transcript is editable. For example, selecting the TranscriptWIndow could put it into a mode where the transcript's state was imported into a more conventional editable text morph, and then when the window was exited, reverted to the standard fast output mode. As you can infer I like having an editable transcript. I can do without it, because Squeak's slow transcript is indeed a PITA, but I'm not sure that speed need preclude editability.

[Request]: Feed MetaRepoForXyz Configs Back to Projects
by Sean P. DeNigris May 11, 2015

May 11, 2015

For example, Soup's config was updated to declare a stable version for 4.0. It was committed to MetaRepoForPharo40, but not to PharoExtras/Soup. It was confusing that loading from the config browser worked, but loading via another config as a dependent project did not (since we use the canonical repo in that use case). Specifically, I am asking that if we update a config, and it's not Pharo xyz-specific (i.e. may break other platforms), that we commit back to the canonical repo or notify the maintainer if we don't have repo access. This policy would obviously be especially easy for any project owned by the Pharo team. Thanks :) ----- Cheers, Sean -- View this message in context: http://forum.world.st/Request-Feed-MetaRepoForXyz-Configs-Back-to-Projects-… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Pending OS-X Cocoa Squeak VM build
by John McIntosh May 11, 2015

May 11, 2015

Morning. I've taken some time to integrate various Pharo and Pyonkee changes into the Squeak OS-X and iOS cocoa source tree, along with converting the code base to ARC and modern Obj-C. Earlier today I ran a Squeak4.5-13680 32bit image on a 64bit client 3488 run, 3421 passes, 23 expected failures, 43 failures, 0 errors, 1 unexpected passes However I need some folks to step forward and validate the results, document what might be broken, look for behaviour anomalies, and refine exactly what plugins are needed in the base system. I also need someone to try this on a 32bit host with 32bit image, and with a current 64bit image (which I don't have) on a 64bit host. Drop me a note and I"ll forward a link to a binary for testing. Shortly I will be integrating these changes into the Cog branch and create an XCode project for building a 64/64 Cog/etc VM. -- =========================================================================== John M.
