[ANN] LMGTWTY: Web Sockets Library for Rack+Rainbows!

[ANN] LMGTWTY: Web Sockets Library for Rack+Rainbows!

[Eric Wong]

LMGTWTY is a Rainbows! (and Zbatery) Rack library for Web Sockets.  It
uses unofficial extensions in rainbows.git for Rack which are subject to
change, but it appears to work well enough for the echo_client.py
example shipped with pywebsocket.

It has not been tested against normal web browsers, though there's
no reason it shouldn't work.

It currently depends on the git version of Rainbows.

http://git.bogomips.org/cgit/lmgtwty.git
http://git.bogomips.org/cgit/rainbows.git

There are no releases yet, just grab from git
(install the wonderful "iobuffer" gem, too).

The API is subject to change (like Web Sockets itself (I think)).  This
was done completely on a whim tonight, with no thought or planning
beforehand.  So I can't say I'm completely happy with the API.

At least I believe I finally understand Ruby 1.9 encodings
after writing Lmgtwty::IO (having read and reread article after
article on it over the past few years)...

Just send and email and follow instructions to subscribe.

One more thing, for both of them, if you have RubyGems 1.3.5,
"make install-gem" works (or "make gem" and then manually
installing the file).

Of course "make install" works too if you're not worried
about uninstalling.

[PATCH] env["hack.io"] for Fiber*, Revactor, Thread* models

[Eric Wong]

This exposes a client IO object directly to the underlying
application.

  In case you already have an installation and just want to patch that,
  this is the patch I made for Rainbows! that exposes the ability to
  be used with LMGTWTY

Testing, all my mails to this ML seem to be getting rejected based on content type, seems Mail.app isn't sending plain, when I tell it to, or it doesn't like my S/MIME

Hi James,

Only text/plain is allowed at the moment.  And looking at your S/MIME
signatures on rack-devel, they're humongous compared to the size of the
message.

This name was too hard to remember for most folks, so
I'm renaming it to Sunshowers:

  sunshowers-TBHja+091Wbby3iVrkZq2A@public.gmane.org

I'd forgotten adding S/MIME to a message means it's not text/plain.

Fair call.
