execute external command?

by Johan Brichau

Hi list, In another thread, Sven pointed me to the environment variables access from within Pharo3 (using Smalltalk os environment). This already eliminates one use case we have for OSProcess, but I fail to find a replacement for the other one: invoking external commands. So, my question: is OSProcess the only way to perform an external command from within Pharo3 ? thanks for the info Johan

Font chooser broken (12704)

by Nicolai Hess

Sean, can you look at my latest submission for 12704. There were some types in your slice := instead of = or each value: aBlock instead of aBlock value:each And an error with Announcements for FontChooser that were sent to the PluggableListMorph too. nicolai

Re: [Pharo-dev] Null Object Pattern

by Carlo

Tried in Pharo3.0 update: #30651 and the following worked: 1. OCASTTranslator class>>initialise Removed line referring to the selector and then re-initialise. 2. RBMessageNode>>isInlineIfNil Removed the reference to the ifNil:ifNotNil: selector so not picked up as inlined. 3. Created a class NullWorld and overrode the #ifNil:ifNotNil 4. Ran a quick test and it seemed to be working. Cheers Carlo On 24 Jan 2014, at 4:13 PM, Sean P.

If I can't do it effectively with the compiler, that could be a good compromise.

Re: [Pharo-dev] asReactiveVariable ????

by Sean P. DeNigris

I agree that it did not belong in a feature-freeze phase. I'm sorry. I didn't realize it would create such a problem (reminds me of substring -> subString ha ha). There are however, valid reasons for changing the name, so let's discuss after the release. ----- Cheers, Sean -- View this message in context: http://forum.world.st/asReactiveVariable-tp4739110p4739127.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Athens Font Problem

by J.F. Rick

While trying to use fonts with Athens is no longer crashing my up-to-date Ubuntu Pharo image (sweet!), there is a weird phenomenon of fonts varying in size. I've created some simple code to showcase it and capture what it looks like: Cheers, Jeff -- Jochen "Jeff" Rick, Ph.D. http://www.je77.com/ Skype ID: jochenrick
