I'm assuming this is the 0.3 release from Rubyforge, is that correct?
In the newest build of IronRuby, @textfield.text.strip and @textfield.text.trim
both work. It also appears we have fixed the String creation bug you mention
(note that '' is a ClrString and "" is a Ruby String):
[11] > rbd
IronRuby 0.3.0.0 on .NET 2.0.50727.4913
Copyright (c) Microsoft Corporation. All rights reserved.
>>> require 'temp.dll'
=> true
>>> Foo.bar
=> 'hello world'
>>> r = Foo.bar
=> 'hello world'
>>> r.trim
=> 'hello world'
>>> r.strip
=> "hello world"
>>> s = System::String.new "fubar"
=> 'fubar'
>>> exit
C:\temp
[12] > gc temp.cs
public static class Foo {
public static string bar() {
return "hello world";
}
}
C:\temp
This build can be built from sources at
http://github.com/ironruby/ironruby.git, or we should have a release in the
next week or so.
