Serialport IO and OS X Lion
by Robert Rice 21 Sep '11

21 Sep '11

Hi devotees, I was using an Obj-C wrapper for serial port IO written by Paolo Bosetti but I found that it no longer works in Lion. Does anyone know what might have changed? Does MacRuby have a better solution for serial IO yet than using an Obj-C wrapper? Thanks, Bob Rice

Hi guys, I'm attempting to use the mysql2 gem with mac ruby. I do a "macruby install mysql2" then copy the gem directory to my vendor directory. when I require vendor/mysql2 I get this error: `<main>': uninitialized constant Encoding::Windows_1250 (NameError) Am I doing something wrong? Thank you very much!

List configuration and Gmail spoofing paranoia
by Eric Christopherson 20 Sep '11

20 Sep '11

Since Google implemented some new anti-spoofing measures in Gmail recently (a few months ago?), messages from certain people to this list show text like this in Gmail: This message may not have been sent by: mattaimonetti(a)gmail.com Learn more Report phishing Matt, I notified you of this when I first noticed it. Laurent, this warning also comes up on your messages. I wonder if there's something slightly wrong with the way the list is set up. I don't get these warnings on any other lists I'm on.

-twolevel_namespace issue?
by Jeremy Hinegardner 18 Sep '11

18 Sep '11

Hey all, I develop the Amalgalite gem[1] and it ships with its own copy of SQLite. It does this as it adds in additional compile-time features, and I try and keep it as current as posssible. The problem is that since MacRuby is linked to CoreServices etc, the sqlite library that ships with OSX gets linked at runtime before the sqlite library that is built into the amalgalite gem extension. I've encountered this before[2] with amalgalite, when it was loaded with my 'hitimes' gem (which on osx links against -framework CoreServes). I am wondering what the appropriate approach is here. I was able to fix this in MRI by compiling MRI with -twolevel_namespace and I think there is an open ticket with ruby-core to see if MRI on osx should be compiled with that flag. I attempted to compile MacRuby with -twolevel_namespace to resolve this, and I was unsuccessful. There appeared to be other flags that conflicted with it. I would expect something like this may also affect the nokogiri gem as limxml2 is also a system library on osx, and may conflict with the version that nokogiri expects. Thoughts? Opinions? I'm sure this is a rare case, Amalgalite may be the only project that could experience an issue like this. What is the best way to handle this in the MacRuby ecosystem? enjoy, -jeremy [1] - https://github.com/copiousfreetime/amalgalite [2] - https://github.com/copiousfreetime/amalgalite/blob/master/lib/amalgalite/sq… -- ======================================================================== Jeremy Hinegardner jeremy(a)hinegardner.org

linking an NSTextView with my AppDelegate
by Brice Ruth 18 Sep '11

18 Sep '11

Good afternoon - I saw a thread from August indicating that there was an issue with Xcode 4 on Lion w/r/t linking in IB (matched exactly what I'm seeing). I went and grabbed the latest Xcode 3.x and installed it on Lion - I now have the old IB, but I still can't seem to see the attrs defined in my AppDelegate when I try to link the TextView. Not sure what I'm doing wrong ... would anyone mind stepping me through in a little more detail or pointing me to a more detailed walk through? I was using Xcode 4 on Snow Leopard and everything seemed to be working peachy ... I'm now on Lion, working on a new NSTextView and I can't get it to link to anything anymore. I saw one response indicating that you need to tell IB to read the files - I see a "Read class files ..." option in the menu - when I point that at my AppDelegate, I get an error dialog in IB, when I point it at main_rb, I don't get an error, but it still doesn't appear to work. I can't make heads or tails of the XML in the .xib, either - so no hope there. Much obliged, Brice Ruth, FCD Software Engineer, Madison WI

macruby produces strings with encodings that differ from MRI
by Steve Clarke 18 Sep '11

18 Sep '11

Code ======== ABC='ABC' puts "ABC[0] encoding is #{ABC[0].encoding}" puts "?\\xff encoding is #{?\xff.encoding}" Output ======== MRI output ABC[0] encoding is US-ASCII ?\xff encoding is ASCII-8BIT macruby output ABC[0] encoding is UTF-8 ?\xff encoding is UTF-8 The encodings reported above did not seem to be effected by the encoding of the source file. I tried both ASCII and UTF-8. When the same code is executed in (mac)irb the results are the same for macirb as they are for macruby. irb for MRI however produces UTF-8 strings in both cases! This seemed very odd but I'm fairly sure it's because I have an environment variable: LANG=GB.UTF-8 When I changed to LANG=GB.US_ASCII irb for MRI rendered 'abc'[0] with US_ASCII encoding. macirb still used UTF-8. (I discovered this when trying to get ruby-mysql to work with macruby. It doesn't work as-is but seems to work with a few mods that use force_encoding to make MRI and macruby produce the same outputs). I abandoned my earlier attempts to use postgres with macruby via the pg gem. It failed regularly but in unpredictable ways associated, as far as I could tell, with memory management problems.
