Nested classes

by Charles Monteiro

Hi, perhaps a bit off topic, but I was wondering from those that brought Traits to ST, what are their thoughts of the use of nested classes such as used in Ruby and other languages. Good idea? If so should Smalltalk integrate these? Why? Why not ? thanks in advance -Charles www.nycsmalltalk.org -- -- View this message in context: http://forum.world.st/Nested-classes-tp3125667p3125667.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Z3950 on OSX: module yaz3 not found

by laurent laffont

Hi Hernan, the strace equivalent on OSX seems to be dtruss (yes I'm learning OSX too :) sudo dtruss -p [pid of process] in the trace I have this: stat("/Users/laurentlaffont/Downloads/Seaside.app/Contents/Resources/yaz3.bundle/Contents/MacOS/yaz3\0", 0xBFF59440, 0xBFF5AB28) = -1 Err#2 stat64("/Users/laurentlaffont/Downloads/Seaside.app/Contents/Resources/yaz3.bundle/Contents/MacOS/yaz3\0", 0xBFF5892C, 0xBFF5AB28) = -1 Err#2 stat("/Users/laurentlaffont/Downloads/Seaside.app/Contents/Resources/yaz3\0", 0xBFF59440, 0xBFF5AB28) = 0 0 stat64("/Users/laurentlaffont/Downloads/Seaside.app/Contents/Resources/yaz3\0", 0xBFF5892C, 0xBFF5AB28) = 0 0 open("/Users/laurentlaffont/Downloads/Seaside.app/Contents/Resources/yaz3\0", 0x0, 0x0) = 12 0 pread(0xC, "\317\372\355\376\a\0", 0x1000, 0x0) = 4096 0 close(0xC) = 0 0 stat("/Users/laurentlaffont/Downloads/Plugins/yaz3.bundle/Contents/MacOS/yaz3\0", 0xBFF59440, 0x1000) = -1 Err#2 stat64("/Users/laurentlaffont/Downloads/Plugins/yaz3.bundle/Contents/MacOS/yaz3\0", 0xBFF5892C, 0x1000) = -1 Err#2 stat("/Users/laurentlaffont/Downloads/Plugins/yaz3\0", 0xBFF59440, 0x1000) = -1 Err#2 stat64("/Users/laurentlaffont/Downloads/Plugins/yaz3\0", 0xBFF5892C, 0x1000) = -1 Err#2 so it looks like the VM is trying to find yaz3 at non standard Unix places (I don't know if it's SqueakVM or OSX related). I've created Contents/Resources/yaz3.bundle/Contents/MacOS/, put yaz lib there, ln -s libyaz.3.dylib yaz3 but no success. I've read good post http://forum.world.st/FFI-Documentation-td2225150.html : Module Location - where the external library file lives - depends on the platform - Mac - pre Snow Leopard - checks VM path and common library paths - Snow Leopard - only looks in VM bundle's Resources file, you must either [5]: - store all external libraries there - ln -s path/to/library path/to/VM/Resources/library_name - Change the VM's Info.plist "SqueakPluginsBuiltInOrLocalOnly" key from "true" to "false." For this SqueakPluginsBuiltInOrLocalOnly I suppose I need to compile a VM ?

Hi Laurent I've read there is a couple of system calll monitors in MacOS, ktrace and dtrace (http://en.wikipedia.org/wiki/Ktrace , http://en.wikipedia.org/wiki/DTrace) so you may attach to the VM and see what's missing?

On 64bit systems you just need to load the 32bit libs by installing the package 'ia32-libs'. On Debian and Ubuntu you can just apt-get install ia32-libs then the one-click app will work just fine. I imagine its the same package name on other distros but I don't know for sure.

Incorrect cursor behavior in right-to-left scripts

by Alex Albitov

Hi all, I noted incorrect cursor behavior in right-to-left script. When right-to-left script (Hebrew for example) is used the cursor should not advance to next character, but stay in its position and let the characters advance as the text is being inserted. Does anybody knows how to change the cursor's behavior? Thank you, Alex Albitov

Thanks Hernan. It still doesn't work. I've also tried to play with LD_LOAD_PATH / LD_LIBRARY_PATH no success.... I want to make it work so I need to learn :) For the mangled function names, on Linux and OSX there's nm. Here's what I get: $ nm -g libyaz.3.dylib | grep ZOOM_connection_create 0000000000046a30 T _ZOOM_connection_create Cheers, Laurent On Sun, Dec 19, 2010 at 6:23 PM, HernÃ¡n Morales Durand < hernan.morales(a)gmail.com> wrote: > Hi Laurent, > > Thanks for reporting.

Re: [Pharo-users] [Pharo-project] serial driver

On Unix/Linux systems you can just read/write the respective device files. That worked in my case.

Pharo on Linux 64bit system

by Alan Rodas

Hello, I recently updated my system to a 64bit one I had trouble running Pharo. I made the one click image run by adding manually the missing libraries to /usr/lib32 but its quite annoing to do that. So I would like to ask Is there a 64 bit vm? Is there a linux package that contains all necessary lib files to run Pharo in a 64 bit linux? I made a zip file with all this libraries so if there's nothing better let me know and I will upload it. Cheers -- Alan Rodas Bonjour
