Re: [Pharo-users] Conveying the usage of an object

by Sergio Fedi

The only other way I can think of doing this is via the virtual categories (which Pharo seems to have) and make them look for "Public" at the beggining of the first comment. Not fancy, but practical. â

Re: [Pharo-users] Conveying the usage of an object

by Mariano Martinez Peck

Sergio, a few times I also wanted that. And the only way of doing it I found was by doing defining protocols like 'public' , 'public - subcategoryX', 'public - subcategoryY' , etc... not sure powerful but simple.

Conveying the usage of an object

by Sergio Fedi

Hi, In other smalltalks, which had the capability of marking a method with more than one category, I could make a method public/private AND it's functional category (accessor, printing, etc) I did this to explicitly show the user which methods I expect to be sent to the object and which ones I don't. It didn't seem to me I can assign more than one category in Pharo, so my question is: How can I deal with this problem? Which is "the Pharo way" to accomplish this?

Re: [Pharo-users] Where to channel questions

by Peter UhnÃ¡k

Sometimes people also post on StackOverflow and then send link to mailing list. SO is generally oriented more on concrete problems and solutions... e.g. "How do I sort a collection?". General discussions, debates, opinions and other are discouraged and downvoted â it doesn't belong there; so best ask such questions here.

Just by chance (have been there before :-( )... Are you starting by double clicking on the image or on the app (and then choose the image). I got bitten by something similar where Pharo didn't pick up the library. Took me some tracing to find out that Mac OS X was using another VM to start the image than the one I was adding the library to :-) After starting the image ry something like $ ps aux | grep Pharo to verify which VM gets picked. If this doesn't help lsof and Instruments are your friends :-) CU, Udo

Oracle FFI - External module not found on OS X

by recursive68＠gmail.com

Thanks, it's giving this, so it's appears to be 32 bit (I compiled with CFLAGS=-m32): /usr/local/lib/libocilib.dylib: Mach-O dynamically linked shared library i386 I think the library is ok, it's just not being found by Pharo when I launch it as an application from the Finder dialog. If I launch Pharo from a terminal window,like ./Pharo, it finds the library using DYLD_LIBRARY_PATH and DYLD_FALLBACK_LIBRARY_PATH, it doesn't even need a sym link in the Pharo Plugins directory and the library is found by Pharo and works. If I create a sym link in the Plugins directory or copy the dylib to the Plugins directory and launch Pharo via the Finder dialog window, it fails with "External module not found", so it appears to be how Pharo and/or OSX sets it library path when launched as an Application that is causing the issue. Thanks.

That is a mistake. We will answer questions on StackOverflow, but it is not our community nor our data, and there is a significant chance questions are closed & deleted.

Could you make sure that you actually have an 32bit or universal version of OCILib? You can check with "file libraryname.dylib". If this is an 64bit-only lib only you'll get that error even if the lib is found. 64bit Only lib: $ file /usr/local/lib/libjpeg.dylib /usr/local/lib/libjpeg.dylib: Mach-O 64-bit dynamically linked shared library x86_64 "Universal" lib: $ file /usr/local/lib/libnanomsg.dylib /usr/local/lib/libnanomsg.dylib: Mach-O universal binary with 2 architectures /usr/local/lib/libnanomsg.dylib (for architecture i386): Mach-O dynamically linked shared library i386 /usr/local/lib/libnanomsg.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 CU, Udo
