Feature #8601


Win32API.rb long life plan

Added by arton (Akio Tajima) almost 9 years ago. Updated 6 months ago.

Target version:


Win32API.rb sits on ext/dl/win32/lib in the source tree.
But DL is deprecated on Ruby 2.0.1, so I'd like to move it from ext/dl/win32/lib to ext/win32/lib because the library is fundamental for Win32 platform.
Also it's required to fit Fiddler.

Attachment is the patched version of Win32API.rb for both DL and Fiddle based on mirich (

Wouldn't it be better to move it out of StdLib into separate gem?

Updated by arton (Akio Tajima) almost 9 years ago

No. Many of Windows users use ruby on enterprise environment that is disconnected from the network. So pre-installed library is required especially fundamentals such as Win32API.

And lib/rubygems/user_interaction.rb and lib/securerandom.rb depend on it.

lib/rubygems/user_interaction.rb has code to use io/console already.

Hello Arton,

In rb-readline project we used DL be able to access Windows API due the warning/removal of Win32API.rb after 2.0

Park Heesob wrote some wrapper on top of DL, and a few days ago we received a pull request that uses Fiddle:

I would love get this sorted out in Ruby itself so we don't have to fake it.

Assigning to Usa for final decision.

Thank you.

Win32API.rb should be removed at 2.1.0.

Hello usa,

This doesn't go against what nobu and arton said?

I can modify both RubyGems and SecureRandom to use Fiddle (for newer versions) but not sure about the enterprise environments that have no access to gems.

Thank you.
