Please, not even a mantainance release in almost a year, so should we spend our time even trying it out any more?

Maybe the souces stored here(https://github.com/IronLanguages/main) would be the newest.

Commented Issue: Rails >=3.0.9 broken because of the Json gem [6553]

MagmaiKH — Sun, 12 Feb 2012 00:18:43 GMT

The json implementation has decided to branch off in two directions as of 1.0: one that is pure ruby and one that is faster and based on C extensions. Because of this, IronRuby can only support Rails <=3.0.8. We should figure out the best way to move forward since Rails is the main reason that people come to Ruby. If it means creating an official fork of Rails to use json_pure then maybe that's the best way to go. Thoughts anyone?

Commented Issue: installing rspec gem fails [5326]

MagmaiKH — Sat, 11 Feb 2012 23:58:54 GMT

igem install rspec leads to the following error message: "can't convert NilClass into String". This is with ironruby 1.1.1. It also means that the ruby gem project template fails when it tries to install the missing gems
Comments: ** Comment from web user: MagmaiKH **

I encountered a lot of non-sense getting this setup and working on Windows 7 x64.

The default installation location of C:\Program Files (x86)\IronRuby 1.1\ appears to cause problems.
Install to C:\IronRuby instead (I think it's the spaces in the path.)
Ensure your environment path includes C:\IronRuby\bin
Close any processes (cmd-shell or MSVC) and relaunch them as administrator.
This will pick-up the new environment path and change the security-whatever to admin.
Then it is possible to successfully install gems and will cut down on many nil-string errors.

The latest rails does not work with IronRuby because the latest json gem uses native C.
See https://github.com/rails/rails/issues/3413
Install rails 3.0.8 as a work-around:
igem install rails -v 3.0.8 -V --no-ri --no-rdoc
This will be -V[erbose] so you'll see what actually fails.
Dump the ri & rdoc, you don't need them (even if they'd be "nice to have").
I just setup a new PC and just did this (2-11-2012) and it works.

Alternatively one could try hacking the rails gem and change the require from json to json_pure (which does not use any native-C).

I'm pressing on with v3.0.8 for now.
Once I learn how all of this web stuff works and the basics of my site working I may take a look at the daunting task of adding native-C support to IR. Windows ~does~ have a POSIX sub-system that can be installed as a component though it is based on BSD, results may be fast/better achieved leveraging cygwin.

Created Issue: regular expression: nested group matching [6723]

igambin — Tue, 24 Jan 2012 12:03:00 GMT

any idea when iron ruby will fully support oniguruma regex (in this case: nested group matching) ?
e. g. stupid example IP-Address-match ... would be quicker the standard way, but its just to show what i mean. This works in ruby
"123.0.0.1".match( /(?<byte>2[0-4]\d|25[0-5]|[01]?\d\d?){0}(?<one>\g<byte>)(?:\.(?<two>\g<byte>))(?:\.(?<three>\g<byte>))(?:\.(?<four>\g<byte>))/)

Commented Issue: GetExecutable always fails in Linux/Mono [3927]

venecia — Thu, 08 Dec 2011 21:01:00 GMT

IronRuby version - IronRuby 0.9.4.0 (1.0 RC2)
Platform - Ubuntu 9.10, Mono 2.4.2.3

Issue description:

GetExecutable always fails. For example this Ruby code
`ls`
produces error:

IronRuby.Libraries:0:in `GetExecutable': ls (Errno::ENOENT)
from IronRuby.Libraries:0:in `CreateProcess'
from IronRuby.Libraries:0:in `CreateProcess'
from :0:in ``'
from (ir):1

In Windows XP / Net v 3.5 this issue is not reproducible
Comments: ** Comment from web user: venecia **

There is a workaround you can do for this using system(). Similar issue is on IronRuby Kernel.system() calls can occasionally not be executed. So i wrote this override:

module Kernel

alias :oldSystem :system

def system(str)

segs = str.split(" ")

program = segs[0]

arguments = segs[1..segs.length-1].join(" ")

process = System::Diagnostics::Process.new()

process.StartInfo.FileName = program

process.StartInfo.Arguments = arguments

process.StartInfo.UseShellExecute = false

process.Start()

process.WaitForExit()

return process.ExitCode()

end

this essentially overrides the system() call with a similar call using C# libraries. It does not set $? though but does return the exit code. A similar equivalent for `cmd` could be written fairly easily i'd imagine.
