Sure! Mono::Unix::Native::Passwd[http://www.go-mono.com/docs/index.aspx?link=T:Mono.Unix.Native.Passwd](http://www.go-mono.com/docs/index.aspx?link=T:Mono.Unix.Native.Passwd)and Mono::Unix::Native::Group[http://www.go-mono.com/docs/index.aspx?link=T:Mono.Unix.Native.Group](http://www.go-mono.com/docs/index.aspx?link=T:Mono.Unix.Native.Group)that are returned from the Mono::Unix::Native::Syscall[http://www.go-mono.com/docs/index.aspx?link=M:Mono.Posix.Syscall.getusername(System.Int32](http://www.go-mono.com/docs/index.aspx?link=M:Mono.Posix.Syscall.getusername(System.Int32)functions have UInt32, System.String, and System.String[]. System.String is no biggie, and I’m finding .to\_i on a System.UInt32 is still displayed as System.UInt32, so I suppose that’s not an issue, either. MRI displays Fixnum as the type, and I was trying to get the correct types back from the functions. That leaves MRI’s Array to Mono’s System.String[]. My current implementation is just a Ruby module wrapping calls to the Mono functions and returning the appropriate types. Most of it is working, though without being able to run tests easily, I’m testing from the command line. I still need to add conditionals to return nil if it’s run on Windows. I suppose I also need to conditionally load the Mono.Posix.dll if it’s on Windows, too. I’m about to finish the basic implementation and post to github[http://github.com/panesofglass/ironruby/blob/linux/Merlin/External.LCA\_RESTRICTED/Languages/IronRuby/Etc/IronRuby.Libraries.Etc/etc.rb](http://github.com/panesofglass/ironruby/blob/linux/Merlin/External.LCA_RESTRICTED/Languages/IronRuby/Etc/IronRuby.Libraries.Etc/etc.rb).

Nice work. A few suggestions: - ``` You can move the file to ``` C:\M0\Merlin\Main\Languages\Ruby\Libs. - ``` Use System::Environment:: ``` System::Environment.OSVersion.Platform to detect the OS (see e.g. Win32API.rb in Libs). - ``` Rather than check for the platform in every method it might ``` be better to define the methods differently on Windows.

I’ve posted all the type fixes, but since I can’t compile master, I’m hesitant to rebase. What should I do? Also, I still haven’t gotten to the tests. Looks like the current ones all expect nil and assume Windows. Are those the real rubyspec specs? Sent from my iPhone ---

If you run “mspec ci library\etc”, that runs the real RubySpec specs. irtests does run a command like “mspec ci lib” which will run the Etc RubySpec specs. [http://wiki.github.com/ironruby/ironruby/rubyspec](http://wiki.github.com/ironruby/ironruby/rubyspec) might be useful to you about how these scripts work. The RubySpecs are supposed to be working on all platforms. The specs use checks like “platform\_is :windows” or “platform\_is\_not :windows” to have versions for all OSes. I am surprised that the current ones expect nil. You can fix them to have versions of the specs that work on Unixes. You can run the tests against MRI using “mspec –tr” to ensure that the spec you add is correct. If you can streamline the development process for Mono, that will be great so others have an easier time in the future… From: [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) [[mailto:removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)] On Behalf Of Ryan R.

Great. I’ve been working on cleaning up the file paths so that I can run the specs (and irtests). The problem seems to be just having ‘\’ hard-coded everywhere. I’m changing this to File.join(“abc”,“xyz”). I’ve still got a few remaining, notably ir.cmd and irtests.rb. Then I’ll get on the specs for Etc. Those really shouldn’t be hard to write up as I’ve typed them over and over into the REPL the last few days. 🙂 Cheers, Ryan ---

You should add new/updated specs to MERLIN\_ROOT/../External.LCA\_RESTRICTED/Languages/IronRuby/mspec/rubyspec so that all IronRuby devs will immediately start running the new/updated specs (after your changes get pulled into the IronRuby master repo). Jim will then periodically push these back to the RubySpec git repo.

[http://wiki.github.com/ironruby/ironruby/rubyspec](http://wiki.github.com/ironruby/ironruby/rubyspec) might be useful to you about how these scripts work. The RubySpecs are supposed to be working on all platforms. The specs use checks like “platform\_is :windows” or “platform\_is\_not :windows” to have versions for all OSes. I am surprised that the current ones expect nil. You can fix them to have versions of the specs that work on Unixes. You can run the tests against MRI using “mspec –tr” to ensure that the spec you add is correct. If you can streamline the development process for Mono, that will be great so others have an easier time in the future… From: [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)[mailto:removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) [[mailto:removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)[mailto:removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)] On Behalf Of Ryan R.

The fact that etc is a class is my bad. I was just getting enough implemented in order to pass some specs and use libraries that expected the nil on Windows.

I’ve posted an initial “complete” implementation, though I have only done basic testing. I have a couple of TODO’s remaining and some cleanup, as well as writing actual specs. I still don’t have tests running. You can find the module here: [http://github.com/panesofglass/ironruby/blob/linux/Merlin/External.LCA\_RESTRICTED/Languages/IronRuby/Etc/IronRuby.Libraries.Etc/etc.rb](http://github.com/panesofglass/ironruby/blob/linux/Merlin/External.LCA_RESTRICTED/Languages/IronRuby/Etc/IronRuby.Libraries.Etc/etc.rb) Not the prettiest thing in the world, but I just wanted to get it working.

System.String is no biggie, and I’m finding .to\_i on a System.UInt32 is still displayed as System.UInt32, so I suppose that’s not an issue, either. MRI displays Fixnum as the type, and I was trying to get the correct types back from the functions. That leaves MRI’s Array to Mono’s System.String. My current implementation is just a Ruby module wrapping calls to the Mono functions and returning the appropriate types. Most of it is working, though without being able to run tests easily, I’m testing from the command line. I still need to add conditionals to return nil if it’s run on Windows. I suppose I also need to conditionally load the Mono.Posix.dll if it’s on Windows, too. I’m about to finish the basic implementation and post to github[http://github.com/panesofglass/ironruby/blob/linux/Merlin/External.LCA\_RESTRICTED/Languages/IronRuby/Etc/IronRuby.Libraries.Etc/etc.rb](http://github.com/panesofglass/ironruby/blob/linux/Merlin/External.LCA_RESTRICTED/Languages/IronRuby/Etc/IronRuby.Libraries.Etc/etc.rb).
